-POLYHEDRA GENERATION
-
-For the purpose of this program it's not sufficient to know the polyhedra
-vertexes coordinates. Since the morphing algorithm applies a nonlinear
-transformation over the surfaces (faces) of the polyhedron, each face has
-to be divided into smaller ones. The morphing algorithm needs to transform
-each vertex of these smaller faces individually. It's a very time consoming
-task.
-
-In order to reduce calculation overload, and since all the macro faces of
-the polyhedron are transformed by the same way, the generation is made by
-creating only one face of the polyhedron, morphing it and then rotating it
-around the polyhedron center.
-
-What we need to know is the face radius of the polyhedron (the radius of
-the inscribed sphere) and the angle between the center of two adjacent
-faces using the center of the sphere as the angle's vertex.
-
-The face radius of the regular polyhedra are known values which I decided
-to not waste my time calculating. Following is a table of face radius for
-the regular polyhedra with edge length = 1:
-
- TETRAHEDRON : 1/(2*sqrt(2))/sqrt(3)
- CUBE : 1/2
- OCTAHEDRON : 1/sqrt(6)
- DODECAHEDRON : T^2 * sqrt((T+2)/5) / 2 -> where T=(sqrt(5)+1)/2
- ICOSAHEDRON : (3*sqrt(3)+sqrt(15))/12
-
-I've not found any reference about the mentioned angles, so I needed to
-calculate them, not a trivial task until I figured out how :)
-Curiously these angles are the same for the tetrahedron and octahedron.
-A way to obtain this value is inscribing the tetrahedron inside the cube
-by matching their vertexes. So you'll notice that the remaining unmatched
-vertexes are in the same straight line starting in the cube/tetrahedron
-center and crossing the center of each tetrahedron's face. At this point
-it's easy to obtain the bigger angle of the isosceles triangle formed by
-the center of the cube and two opposite vertexes on the same cube face.
-The edges of this triangle have the following lenghts: sqrt(2) for the base
-and sqrt(3)/2 for the other two other edges. So the angle we want is:
- +-----------------------------------------------------------+
- | 2*ARCSIN(sqrt(2)/sqrt(3)) = 109.47122063449069174 degrees |
- +-----------------------------------------------------------+
-For the cube this angle is obvious, but just for formality it can be
-easily obtained because we also know it's isosceles edge lenghts:
-sqrt(2)/2 for the base and 1/2 for the other two edges. So the angle we
-want is:
- +-----------------------------------------------------------+
- | 2*ARCSIN((sqrt(2)/2)/1) = 90.000000000000000000 degrees |
- +-----------------------------------------------------------+
-For the octahedron we use the same idea used for the tetrahedron, but now
-we inscribe the cube inside the octahedron so that all cubes's vertexes
-matches excatly the center of each octahedron's face. It's now clear that
-this angle is the same of the thetrahedron one:
- +-----------------------------------------------------------+
- | 2*ARCSIN(sqrt(2)/sqrt(3)) = 109.47122063449069174 degrees |
- +-----------------------------------------------------------+
-For the dodecahedron it's a little bit harder because it's only relationship
-with the cube is useless to us. So we need to solve the problem by another
-way. The concept of Face radius also exists on 2D polygons with the name
-Edge radius:
- Edge Radius For Pentagon (ERp)
- ERp = (1/2)/TAN(36 degrees) * VRp = 0.6881909602355867905
- (VRp is the pentagon's vertex radio).
- Face Radius For Dodecahedron
- FRd = T^2 * sqrt((T+2)/5) / 2 = 1.1135163644116068404
-Why we need ERp? Well, ERp and FRd segments forms a 90 degrees angle,
-completing this triangle, the lesser angle is a half of the angle we are
-looking for, so this angle is:
- +-----------------------------------------------------------+
- | 2*ARCTAN(ERp/FRd) = 63.434948822922009981 degrees |
- +-----------------------------------------------------------+
-For the icosahedron we can use the same method used for dodecahedron (well
-the method used for dodecahedron may be used for all regular polyhedra)
- Edge Radius For Triangle (this one is well known: 1/3 of the triangle height)
- ERt = sin(60)/3 = sqrt(3)/6 = 0.2886751345948128655
- Face Radius For Icosahedron
- FRi= (3*sqrt(3)+sqrt(15))/12 = 0.7557613140761707538
-So the angle is:
- +-----------------------------------------------------------+
- | 2*ARCTAN(ERt/FRi) = 41.810314895778596167 degrees |
- +-----------------------------------------------------------+
