"There must be a proper theory of place other than 'To Find Kalamazoo, look in F3'."--from Euclid's Window, The Story of Geometry from Parallel Lines to Hyperspace, by Leonard Mlodinow

You Are Here...There...Everywhere

To determine Latitude, imagine a Little Earth, and 3 Little Points. {This should sound familiar to You, since You dreamt it when You were 8}.

Take one point P1 and put it at the North Pole, and the second point P2 and put it at the Center of the Little Earth, and use the third point P3 to Mark where you are on the Little Earth.

Now draw a line from the North Pole straight through the point at the Center, to the other end of the Little Earth. This First line, Line 1, forms the Little Earth's axis of Rotation.

Then draw a line from the Point where You are standing through the point at the Center of the Little Earth, Line 2,  to form an angle, α , with the Little Earth's axis of rotation, that first line You drew.

The two lines act like a Protractor and that angle α is a generic way to determine Your Latitude.

Determine Latitude Using
The Little Earth
A Portion of the Fano Plane

Which is a great way of thinking of where You are, but will not help Us find each other.

For that We have to imagine a Big Earth (Way Way Bigger than Our Little Earth). Something on the Cosmic scale, that would be the Celestial Sphere, the map of Stars that circles the globe.

Imagine the Big Earth around the Little Earth, the globe that is now the Core (where You are standing & spinning) of the Celestial Sphere.

This will help to determine Longitude, sinceYou are not a Flatlander and need at least these 2 coordinates to determine where You are exactly in 3D.

Remember, since the Earth Rotates 360 degrees in 24 hours, the Stars over Your head are going to move about 15 degrees every hour, so that someOne standing West of You will See the Same Sky an hour later. Which has direct associations to the Fano Plane (diagram below. see also 'kissing circles' and Appolonian Network):

If You are at the Equator (to help me do the math) that translates to distance of about 1000 miles in that much time.

So, You look up at the Sky over where You are standing, and pick a star--any star, that You may be familiar with and note the local time it rises above the horizon, its Right Ascension (RA).  The reference, or baseline is the star γ Aries at 0 hours RA, the First Star in Aries where it crosses the Celestial Equator on the First Day of Spring.

Since there are Apps for this, just point Your PDA at Triangulum Australis, I think He Said 'The Second Star on the Left' and make a note of its RA in Hours-Minutes-Seconds (this presumes that You may be somewhere in the Southern Hemisphere of the Little Earth). {But if I got that wrong, since I heard this while under duress, and wish I had written it down to be sure so many years ago, make a note of the Second Star on the Right RA , too.}

Triangulum Australis
A Constellation in the Southern Hemisphere
No matter what, He Will Find You. You already know His Voice, so don't think too much about what He may look like, since there is usually some type of distortion due to Projection, but I can assure You, He is either Your Heavenly Father or Your Brother, and Either One will take You where You belong--to be with the Ones who love You.{Knowing that no matter who or what it is You think is going on around You, and what ever disinformation or misinformation is propagated through rumor mills or media channels, they are collectively  Nothing but Remnants, Effigies, Residue of things and people gone by, because they lie in order to sever Our Ties of Kinship and in so doing work corruption on the Little Earth

فَهَلْ عَسَيْتُمْ إِن تَوَلَّيْتُمْ أَن تُفْسِدُوا فِي الْأَرْضِ وَتُقَطِّعُوا أَرْحَامَكُمْ (47:22  

47:22 Would you, perchance if You were given Dominion in the Earth, work corruption and Sever Your Maternal Bonds (bonds of kinship, literally, 'sever/cut off Your wombs/matrices/'Places of Mercy')?

Which is exactly what they do when they spread their conspiracy theories of UFOs  and aliens.

Recall that God made everything first, then He Created the Human Being--meaning that the Human Being was to be the Ultimate Creation--meant to Evolve or Reach the Highest form of Creation, but now what have We?}

And the reason that no matter how far You wander off or how big the Universe gets, it's no big deal for Him to find You?--The simplest, 2D planar point group, the Fano Plane PG(3,2)!
{I just answered my own question, must be another from of insanity}.

Can You imagine how it feels to an ant when it ventures off that ant hill? Apparently, even the ants know that As Above, So Is Below...{oops, did it again.}

And He Probably Triangulates with nothing more sophisticated than using 2 Dimensional finite geometry to wend His Way throughout the 'flat, not moving Earth' and the infinite (Multi-Dimensional) Cosmos--->
What is the simplest, smallest, ...perfect universe...a complex universe of breathtaking, abstract, beauty...consisting of only 7 points, 7 lines and their dual? 
{I'll let someone who knows what He's talking about answer that one..} 
According to one Mathematician, (paraphrasing): 
'The 2D planar point group, the Fano Plane PG(3,2) is......the smallest, perfect universe...a complex universe of breathtaking, abstract, beauty...consisting of only 7 points and 7 lines; the smallest project space over the field Z2  with 15 points,  35 lines and 15 planes.  
A space whose overall design incorporates and improves many of the standard features of the 3D Euclidean space we think we live in..the smallest 3D projective space...that plays an important and core role in many fields of mathematics, inlcuding combinatorics, group theory, and geometry'--Burkard Polster, 2001
In non-Euclidian geometry parallel lines meet (intersect) at a point (just like when drawing a perspective of train tracks on paper, they seem to meet at the 'vanishing point'), and that is why the Fano plane is a good 2D small-scale model of the larger 3D Celestial Sphere with the Little Earth at its Core (Your 'Big Earth/Little Earth' dream).

In fact, the Fano plane is the smallest projective plane and probably why the Pyramids were built and are still standing. And it is no mere chance that the projective plane is sometimes called a 'twisted sphere'--'a surface without boundary derived from a usual plane by addition of a line at infinity

'Just as a straight line in projective geometry contains a single point at infinity at which the endpoints meet, a plane in projective geometry contains a single line at infinity at which the edges of the plane meet.  
Lio Comic Strip August 28, 2012
A projective plane can be constructed by gluing both pairs of opposite edges of a rectangle together giving both pairs a half-twist (The Reverse would be Unfolding such a surface). It is a one-sided surface, but cannot be realized in three-dimensional space without crossing itself.'

Projective Plane From A Sphere

A finite projective plane of order n is formally defined as a set of n^2+n+1 points with the properties that:
1. Any two points determine a line,
2. Any two lines determine a point,
3. Every point has n+1 lines on it, and
4. Every line contains n+1 points.
(Note that some of these properties are redundant.) 
A projective plane is therefore a symmetric (n^2+n+1n+1, 1) block design. 
An affine plane of order n exists iff a projective plane of order n exists.

Innie_ Audi Belly Buttons
The 3 points at each vertex of the triangle defining the Fano plane, represent these vanishing points (You took technical drawing classes so You get this).  They serve to define 'Outside' because, as You know, there is no way to define the 'Inside' without SomeThing or SomeOne being on the 'Outside'. {kind of like there is no way to know Up from Down in outer space; now, You know why You were so facinated by your belly button when You were 2 years old}.

But since we are still biding our Time in the 'Real' world, having missed our ride out of here so many years ago, I suspect we are to put this to more pragmatic, concrete use than just appreciating its abstract beauty---I mean, really, what do mathematicians know? --they, too, are still stuck on the ground.

Stereographic Projection When
Representing the Earth as a Flat Surface

The Lehmers (1974) found an application of the Fano plane for factoring integers via quadratic forms. Here, the triples of forms used form the lines of the projective geometry on seven points, whose planes are Fano configurations corresponding to pairs of residue classes mod 24 (Lehmer and Lehmer 1974, Guy 1975, Shanks 1985). The group of automorphisms (incidence-preserving bijections) of the Fano plane is the simple group of group order 168 (full automorphisms== 7 generators x  the 24 automorphisms of the tetrahedron symmetry group).--excerpt from Wolframalpha

Rand & McNally Cartogrophers  Extraordinaire
A long time ago, Ptolomy published Geographia, and used a similar method, like stereographic projection, to represent the Earth as a Flat Surface, and he used Latitude and Longitude coordinates to locate about 8000 places he knew of at the time and gave instructions for map making (cartography).

It served as as standard reference for 100 years, but made no progress under Roman rule. When a Christian mob sacked the library at Alexandria, Geographia disappeared along with other math and Greek works (never mind how they disposed of the Greek worker Hypatia).

With the fall of the Roman Empire, "the new age found a civilization as much in the dark about describing their place in space as was about the theorems and relations among spatial objects."--That's why We take care of books...

Anyhow, using 'irrational' numbers was also lost and this 'bad math' did not resurface until Cantor and Dedekind rediscovered it in the late 19th century (that's probably the punishment they deserved for what they did to Hypatia).

From the Middle Ages until that time scientists and mathematicians had been using them "happily, if awkwardly, anyway for the simple reward of getting the right answer outweighing having to wield unpleasant numbers 'that did not exist'."

This 'illegal' math is quite common today and we take it for granted. 

There was also Dirac's delta function which posed a quandary for mathematicians; one that is simply =0 everywhere except at 1 point, where the value is infinity, but when applied in calculus or certain math operations typically gives us finite non-zero answers. Then the mathematician Laurent Schwartz (one more thing we can thank the French for) came along and showed that 'the rules of math can be redefined to allow using the delta function, opening up a whole new discipline of math and later buttressing 'illegal' physics concepts like quantum field theories, as well.  

As of 2001, no one had yet successfully shown that, 'mathematically speaking, such theories legally exist.'

Which is just as well, since from God's Point of View (wayy out there on the Outside, at Infinity), Nothing Really Happens; according to Mom and Psalm 93:1 "...for God hath established the world, which shall not be moved." What most people don't realize, is the tacit caveat, 'unless God moves it'. 

An antipode to the stance taken by the general population, and teenagers (who think they know everything) without stopping to consider that even the greatest minds throughout history had reason to know better. 

When we next see each other, You can let me know if You had chanced on anyone of that ilk.

And for practical purposes, geometry found more inroads as people tried to describe in comprehensive terms what they saw in the world around them. One instance being that of motion in different frames of reference, like a deck hand on a boat who slides his hand down a mast appears to the seaman as though his hand is moving in a vertical direction (perpendicular to the deck), but to someone watching from the shore the deck hand's motion is running on a diagonal while the boat traverses the water.

The story continues, that Decartes translated space into numbers (quantitatively, not simply by construction), or phrased geometry in terms of algebra. Decartes distance formula being deeply tied to Euclidean Geometry and key to understanding both Euclidean and non-Euclidean geometries; serving as the basis for much of his contribution to physics.

Yet, Rene delayed publishing for 19 years--in fact, "...he delayed publishing anything until he was 40. What was he afraid of? The usual suspect. The Catholic Church."

Then came Gauss, who contributed to the development of non-Euclidean hyperbolic space.
"Through the centuries, mathematicians who attempted to prove the parallel postulate (Euclid's 'parallel lines never meet') as a theorem came close to discovering a strange and exciting new kind of space, but each of them was hampered by a simple belief: that the postulate was a true and necessary property of space."
...everyone but Gauss, who basically acceded to his own observation that a line is a curve of some sort, rather than clinging to Euclid's postulate, which in turn led to the rediscovery of curved spaces. A property that Gauss had to propose when applying the basic tenet that "superposition is a way to check for congruence or equivalence of geometric shapes."
There are other examples of non-Euclidean geometries.

In turn, Poincare developed his model of hyperbolic space, which was not just the 'model', but hyperbolic space in 2D, concluding that all possible mathematical descriptions of hyperbolic planes are isomorphic, in other words, 'the same.'

Poincare's lines are analogous to great circles, a rediscovery of what the Ancients knew about geodesics. The Equator being a curve of constant latitude.
"The view from outer space is not the view of the indigenous people of Noneuclid (a fictional professor sending her students out to measure distance across the globe). To her, there is no 'center of the earth', and as Gauss showed possible, there is no 'outer space.'...the non-Euclidean, not hyperbolic space, but the space appropriate to the surface of the globe: elliptical space."
Meaning, the great circles intersect, and the sum of the angles of the triangle on such a surface is greater than 180 degrees, (as compared to that for hyperbolic space being less than 180 degrees, and for Euclid in a plane it is equal to 180). The Geo-metrics that define what we think of  as 'hyperspace', 'subspace', and 'flat earth'.

And these concepts laid the foundation for Riemann's differential geometry in 1915, in the vernacular having to define 'place vs. space', where place is 'part of a space' occupied by a specific object:

"The question of the valididty of related to the question of the internal basis of metric [distance] relationships of the space...we must seek the ground of its metric relations outside it, in the binding forces which act on it..."--Georg Friedrich Bernhardt Riemann

And then breakthroughs by Klein, Piola, and Hilbert following soon after, applying tensor mathematics and algebraic curves.

Godel's theorem proved that in a system of sufficient complexity, such as the theory of numbers, there must exist a statement that cannot be proved either true of false.

A corollary of which: 
There must exist a true statement that cannot be proved. 
Example: There Is A God.
And all this ground-breaking, thought-provoking, formulations, rediscoveries and challenges swung like a pendulum back to the Flat Earth, again, considering what Clifford had proposed in 1870:

William Kingdon Clifford maintained:
"I hold in fact:
  1. That small portions of space are of a nature analogous to little hills on a surface which is on average flat.
  2. That the property of being curved or distorted is continually passed on from one portion of space to another after the manner of a wave.
  3. That this variation of the curvature of space is really what happens in that phenomenon which we call the motion of matter..." 
And while Clifford professed his position based on instinct alone, he got it right! Which in turn inspired Einstien's space-time and warpage ideology encapsulated in his Relativity theories.

Eventually leading to concepts like supersymmetry and string theory.

As for them-thar-hills Clifford was intuitively talking about-- be they mounds, mountains or dunes...Quran anticipated someone wondering about them.

Ok, Ok... SO, Let's try a W-Curve...

A Pantograph is a jointed device for copying a plane figure to any desired scale. It incorporates a pair of face bows fixed to the jaws, used for inscribing centrically related points and arcs leading to the points on segments relatable to the three craniofacial planes.

فَكَانَ قَابَ قَوْسَيْنِ أَوْ أَدْنَى (53:9) 
53:9 Until He (Gabriel) was 2 Bow's Lengths or Lower (Closer) 

A throw –  in German ‘wurf’, refers to a series of four points on a line which trace the 1-Dimensional motion of a point on a projective line, the W-curve.
The etymology for the ‘W-curve’derives from the German "Weg-Kurve" meaning "pathcurve", which include conics, logarithmic spirals, exponentials (i.e., y = x3 ), logarithms and the helix, but not sinusoidal functions.  

The term Throw (Wurf) was first introduced to avoid the metrical implication of a ratio. The Algebra of Throws provides an approach to numerical propositions, usually taken as axioms, but proven in projective geometry.
In the diagram ..., it turns out that the cross-ratio of a series of 4 points, taken in afixed order, does not depend on the choice of a line L, and is said to be invariant of the 4-tuple of lines {Li}.This can be understood as follows: if L and L′are two lines not passing through Q then the perspective transformationfrom L to L′with the center Q is a projective transformation thattakes the quadruple {Pi} of points on L into the quadruple {Pi′}of points on L′. Therefore, the invariance of the cross-ratio under projective automorphisms of the line implies (in fact, is equivalent to) the independence of the cross-ratio of the four collinear points {Pi} on the lines {Li} from the choice of the line that contains them. 
For points on a projective line (like the W-curve), the cross-ratio, (aka, double ratio and anharmonic ratio), is a special number associated with such a series of an ordered quadruple of collinear points.
If the four points are represented in homogeneous coordinates by vectors (ie., objects that transform like first-rank tensors) a,b,c,d such that c=a+b and d=ka+b, then their cross-ratio is k.
The cross-ratio is essentially the only projective invariant of a quadruple of points, it being preserved by fractional linear transformations, which underlies its importance for projective geometry. If four points lie on a straight line L in R2 then their cross-ratio is a well-defined quantity, because any choice of the origin andeven of the scale on the line will yield the same value of the cross-ratio.
In the Cayley–Klein model of hyperbolic geometry, the distance between points is expressed in terms of a certain cross-ratio.
Since the cross-ratio is invariant under projective transformations, it follows that the hyperbolic distance is invariant under the projective transformations that preserve the conic C. Conversely, the group G acts transitively on the set of pairs of points (p,q) in the unit disk at a fixed hyperbolic distance.
{ For a generalized conic, in this case a unit circle, any two points in the unit disk, pq, the line connecting them intersects the circle in two points, a and b. The points are, in order,apqb.  The distance between p and q in the Cayley–Klein model of the plane hyperbolic geometry can be expressed as
... (the factor 1/2 is needed to make the curvature −1).}

In the language of group theory, the symmetric group S4 acts on the cross-ratio by permuting coordinates. The kernel of this action is isomorphic to the Klein four-group K. This group consists of 2-cycle permutations of type  (ab)(cd)  (in addition to the identity), which preserve the cross-ratio. The effective symmetry group is then the quotient group S_4/K, which is isomorphic to S3.
There are a number of definitions of the cross-ratio. However, they all differ from each other by a suitable permutation of the coordinates. In general, there are six possible different values the cross-ratio ( z1 z2 z3 z4) can take depending on the order in which the points zi are given.

Since there are 24 possiblepermutations of the four coordinates, some permutations must leave the cross-ratio unaltered. In fact, exchanging any 2 pairs of coordinates preserves the cross-ratio:

Cross-Ratio Symmetries, Equivalent Permutations

Using these symmetries, there can then be 6 possible values of the cross-ratio, depending on the order in which the points are given. These are: 
The 6 Possible Values of the Cross-Ratio

For certain values of  λ there are fewer than 6 possible values of the 6 possible values of cross-ratio due to  enhanced symmetry. These values of λ correspond to fixed points of the action of S3 on the Riemann sphere (given by the above 6 functions); in other words, those points with a non-trivial stabilizer in this permutation group.
The first set of fixed points is {0, 1, ∞}. However, the cross-ratio can never take on these values if the points {zi} are all distinct. These values are limit values as one pair of coordinates approach each other:
Limit Values of Cross-Ratio
Due to Enhanced Symmetry Corresponding to Fixed Points

The second set of fixed points is {−1, 1/2, 2}--what is classically called the harmonic cross-ratio, and arises in projective harmonic conjugates

In the real case, there are no other exceptional orbits (See About the Myth-tery, projection/buruj/zodiac).

The most symmetric cross-ratio occurs when 

l = e±ip/3

...the only possible values of the cross-ratio.
The addition of points and multiplication of points, as one would do when adding distances, comprises von Stuadt's work ‘wurftheorie’ or the "algebra of points".
Given the same starting point, find the point midway between their terminal points, aka the harmonic conjugate of infinity with regard to their terminal points, and then find the harmonic conjugate of the initial point with regard to this mid-point and infinity. Generalizing this to add throws (CA,BD) and (CA,BD' ), then finding M the harmonic conjugate of C with regard to D and D' , and then S the harmonic conjugate of A with regard to C and M :(CA,BD) + (CA,BD') = (CA,BS) .\
A definition of the product of two throws is derived in a similar fashion.
A summary statement is given by Veblen & Young given by Theorem 10: "The set of points on a line, with P removed, forms a field with respect to the operations previously defined". 
Another affirmation harmonic conjugates given by the theorem:
The only one-to-one correspondence between the real points on a line which preserves the harmonic relation betweenfour points is a non-singular projectivity.

Excerpt From: Mathematical Approaches To Biomolecular Structure and Dynamics, by Jill P. Mesirov, Klaus Schulten, DeWitt L. Sumners
The complexity of a knot is measured in a natural way by the lattice invariants. In an intuitive manner, M(K), A(K), N(K) as well as m(k), n(K) and r(k), measure the relative lengths, or areas necessary to realize a given knot. 
These measures are all of a sub-additive nature, and the authors conjecture that the last three are all additive. 
Table I (excerpt below) indicates the relative complexities of knots, as measured by M(K). It is instructive to compare this table with rankings obtained by other measures, such as the Mobius energies of knots (reference). That spectrum generally reflects the ranking in Table I, but since energies are real numbers (Re), the ranking contains no ties.

{In knot theory, the crossing number is the minimal number of crossings of any diagram of the knot. It is a knot invariant.
By way of example, the unknot has crossing number 0, the trefoil knot 3 and the figure-eight knot 4.
There are no other knots with a crossing number this low, and just two knots have crossing number 5, but the number of knots with a particular crossing number increases rapidly as the crossing number increases.
Tables of prime knots are traditionally indexed by crossing number, with a subscript to indicate which particular knot out of those with this many crossings is meant (this sub-ordering is not based on anything in particular, except that torus knots are listed first). The listing goes 31 (the trefoil knot), 41 (the figure-eight knot), 51, 52, 61, etc. This order has not changed significantly since P. G. Tait published a tabulation of knots in 1877.}
Excerpt from Table I: In order of increasing energies, the knot crossing numbers are: 
01, 31, 41, 51, 52, 61, 62, 63, 71, 72, 73, 819, 74 
The knot 819 , which one would reasonably expect to have a higher energy than any knot with crossing number 7, appears nevertheless before some knots with crossing number 7. The ranking by M(K) compares well with this progression, except the 819 appears even earlier in the sequence. [Refer to fractional linear groups LF(4,2)]

Surah 77 Mursalat (Transmitters, The Winds, Carriers)
انطَلِقُوا إِلَى ظِلٍّ ذِي ثَلَاثِ شُعَبٍ (77:30
77:30  Experience (split, separate, disassociate) to a Shadow (of) 3-Branches (people, states, listeners, etc.)

Sign 77:30 is Nothing, if not Fascinating. 

Literally, and in context, it directs the reader to experience that very thing they are wont to deny; that being the Resurrection or the capacity for that Final Justice we hear so much about, but seems rarely ever experienced during our stay on Earth. 

And in order to be able to do so, the Person is made to 'split' or 'separate', 'shoot' (as in be discharged rapidly, like firing off a gun, and that's where some classically interpret it as the noun 'fire' or 'flame'), 'divorce'  (oneself of a situation, the antonym for which is 'marriage') in order to experience a  'shadow' or ظِلٍّ , tthil.n of a 3-fold nature, a triad, of sh3b شُعَبٍ.  

The primary meaning of شُعَبٍ  includes 'people,'  'state,' 'folk,' 'rank-and-file (soldiers, workers, columns), 'audience,' 'branch,' 'tree branch'; and the verb form implies 'to pay money,' 'to branch off,' or 'ramify'. 

To ramify means to divide into branches but with the unintended consequence of making a situation more complicated, and making the end result more difficult to achieve (becomes asymptotic).

While I know this isn't about me, I can't help but wonder why this unGodly, reprehensible thing happened to me anyway since I never contested the validity of the Resurrection, or God, or anything that would make me a likely candidate to Experience 77:30 first hand, but I suppose it always goes back to 'them' and so it must be for 'their' benefit.

Surah 16 Bees (An.nahl)
أَوَ لَمْ يَرَوْاْ إِلَى مَا خَلَقَ اللّهُ مِن شَيْءٍ يَتَفَيَّأُ ظِلاَلُهُ عَنِ الْيَمِينِ وَالْشَّمَآئِلِ سُجَّدًا لِلّهِ وَهُمْ دَاخِرُونَ 16:48
16:48 Or can they not see (are they so unaware) that whatever God Creates of anything its shades (shadows) meet from the Right and the Left (var. the North), prostrating humbly to God (دَاخِرُونَ  var. while they are unassuming, or when they are separated, partitioned, set apart (the 3 states are not united, so that they are not fully aware? See Sign 77:30 above about partitioning shadows/columns).

My only consolation is that similar things have happened to better people. Some of whom may have slipped under the Radar. Like Enoch, for example, while in Genesis we get to learn the names of many progenitors, how long they lived, the children they had and that they 'died', Enoch didn't get to 'die' but got to take a walk with God and became 'Not'. (Like Mariam, Elijah, others throughout time who 'died' without a name, and perhaps even the Queen of Sheba).

Genesis 5:24
Enoch walked with God; and he was not, for God took him.

And while Enoch went for a 'walk', Elijah got taken for a 'ride.'

2 Kings 2:11

As they were going along and talking, behold, there appeared a chariot of fire and horses of fire which separated the two of them. And Elijah went up by a whirlwind to heaven.

And while in 'broad strokes' there is a reference that it was not much fun for Mother Mary, either, at least she had a head's up warning, which is more consideration than what I got, and She got a Fair Baby out of the Deal, and we all know not to even say word one about my baby, okay.

{Aside: That's why I tried my best to keep this from happening to any other unsuspecting mark, and since they didn't even take the trouble to make sure I was totally unconscious when they did this (and other unmentionable things to me), I must insist that You Do Not Resuscitate, (if they haven't got around to remanding the body to its family, which they should have done back in 2000).

For one thing, just saying, 'It's not happening to you', while I surfaced to see what they were doing, doesn't mean I could ever forget it or that by magic it didn't happen--so thanks for making me too dirty to ever hope for anything but kissing the dirt). That's Why, if it turns out that I am wrong, and there really is no God, they will all find themselves in a position where they Pray There Is One in earnest...Dad?What are You so proud of bringing her down? Was I ever such a high flyer?!!! Just take a look around.}

In  A Fourier Theory for Cast Shadows, (Ravi Ramamoorthi, Melissa Koudelka, and
Peter Belhumeur, IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE, VOL. 27, NO. 2, FEBRUARY 2005 Feb. 2005), the authors uncover the mathematical convolution structure of cast shadows and analyze them using mathematical convolutions and Fourier basis functions.

Abstract- [paraphrase] Cast shadows are important in computer vision applications, such as lighting-insensitive recognition and surface reconstruction.
Due to nonlocal interactions in non-convex regions, formal analysis is difficult.

Real instances that map closely to canonical configurations like a wall, a V-groove structure, or a pitted surface-- in particular, 3D textures whose surfaces include canonical configurations like V-grooves can serve as a basis to develop formal analysis of cast shadows.
Theoretically, many configurations can be mathematically analyzed using convolutions and Fourier basis functions.

The authors’ analysis uncovers the mathematical convolution structure of cast shadows and shows strong connections to recent signal-processing frameworks for reflection and illumination.
Considering lighting variability over nearly flat textured surfaces such as a wall or moss, assuming a fixed Point Of View, the expectation is that variation in illumination (the same purpose the Sun serves as it courses the Sky throughout the day) should correspond to a simple Lambertian cosine-dependent relationship. Cast shadows play a major role, however, that leads to effects that are quantitatively described and mathematically explained here.
Surah 25 Al. Furqan (The Criterion, 'The Norm, Standard, Gauge/Gage, Principle, which to decide/discern/judge/establish... wrong from right (True from False; Light from Shadow)')
أَلَمْ تَرَ إِلَى رَبِّكَ كَيْفَ مَدَّ الظِّلَّ 
وَلَوْ شَاء لَجَعَلَهُ سَاكِنًا
 ثُمَّ جَعَلْنَا الشَّمْسَ عَلَيْهِ دَلِيلًا (25:45   
25:45 Do You See How Your God (Lord, Sustainer) Extends (Lengthens) the Shadow (Shade), and if He Wills He Can Make it Stand Still; and then We Made the Sun to Have Influence Over it (its guide, pilot, director).
Cast shadows have a simple convolution structure amenable to Fourier analysis, meaning a strong link between the mathematical properties of visibility and those of reflection and illumination (but ignoring cast shadows) for which Basri and Jacobs and Ramamoorthi and Hanrahan have recently derived signal-processing frameworks.  
The incident flux of radiant energy per unit area, or irradiance, is a convolution of the lighting and the clamped cosine Lambertian reflection function, an analogous result for cast shadows as convolution of the lighting with a Heaviside step function canalso be realizedwhich also generalize Soler and Sillion’s convolution results for shadows when source, blocker, and receiver are all in parallel planes—for instance, V-grooves that do not contain any parallel planes.  
The paper builds on a rich history of previous work on reflection models, and the properties of 3D textures. While the analytic formulae are derived considering the standard V-grooves used in many of these previous reflection models, it differs in considering cast shadows because of complex illumination, deriving a convolution framework, and analyzing the eigenstructure of visibility, aiming to derive a particular convolution formula for shadows directly, rather than considering a general integral involving the illumination, reflective properties of the surface, and visibility.  
To make the math simple, the authors begin in Flatland, a 2D slice through the viewpoint. A V-groove model, where the visibility is locally monotonically changing, serves as the model to develop the Convolution Formula for Shadows to find the irradiance E(x,β) as a function of groove angle β= [-β1, +β2] and the distance along the groove, x. 
Four Common Shadow Scenarios

Without loss of generality, only the right side of the groove is taken into consideration and the incident cosine term is neglected. {This cosine term may be folded into the illumination function if desired, as the surface normal over a particular face (side) of the V-groove is constant.} 

In a nutshell formalizing the idea of convolution for cast shadows suggests using the frequency space basis but that many more basis functions are required above the order 2 harmonics that are adequate for irradiance. And the results indicate a theoretical link between cast shadows and convolution formulae for their dual--irradiance, and more general non-Lambertian materials.

The authors derived the following orthonormal basis functions as being useful for analyzing cast shadows in 3D textures:

Orthonormal basis functions for 3D cast shadow analysis.
Boundary Conditions (Limits) for Odd Legendre Polynomials are automatically satisfied since they vanish at θ= π/2 or cos θ=0.
 Using only odd terms is similar in some ways to spherical harmonic constructions over the hemisphere.

Since the derived basis functions involve Legendre polynomials over q and Fourier basis functions over φ they are closely related to spherical harmonics but specialized to the hemisphere. Using only odd (sum  odd) Legendre Polynomials inhibits representing non-zero functions at  θ= π/2, but this may partially be corrected by adding a zeroth order basis term or a constant.

Their form is a simple product of 1D functions in q and φ and is simpler than for Zernike polynomials, spherical harmonics, or hemispherical harmonics. And for diffuse textures, due to visibility and shading effects, the intensity goes to 0 for lighting at grazing angles. Simply adding extra basis functions for the even Legendre Polynomials (that go to 0 at θ= π/2) precludes orthonormalization, and leads to slow convergence or inaccuracies, however, numerical methods such as Gram-Schmidt orthogonalization procedure are available to enable this practice.The hemispherical basis functions for cast shadows were constructed in three ways:

  1. adapted from a domain of cylinder topology;
  2. using Zernike polynomials that are adapted from the disk;
  3. and hemispherical harmonics adapted directly from the sphere.
In developing a parametric for cast shadows, the main analytic results made it clear that the Net Visibility of Irradiance is a simple Convolution of the Incident Illumination with the Heaviside Step Function that accounts for cast Shadow effects.(Makes it easy to see Your Mom, which means You don't need to look too hard to find your Dad, since He is usually right behind her or just ahead of her, if He's not raiding her panty-drawer).

This naturally led to deriving a product formula in the Fourier or frequency domain:
