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 (float)Math.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 u(float)Math.sing 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*(float)Math.sqrt(2))/(float)Math.sqrt(3) + CUBE : 1/2 + OCTAHEDRON : 1/(float)Math.sqrt(6) + DODECAHEDRON : T^2 * (float)Math.sqrt((T+2)/5) / 2 -> where T=((float)Math.sqrt(5)+1)/2 + ICOSAHEDRON : (3*(float)Math.sqrt(3)+(float)Math.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 cros(float)Math.sing 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: (float)Math.sqrt(2) for the base +and (float)Math.sqrt(3)/2 for the other two other edges. So the angle we want is: + +-----------------------------------------------------------+ + | 2*ARCSIN((float)Math.sqrt(2)/(float)Math.sqrt(3)) = 109.47122063449069174f 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: +(float)Math.sqrt(2)/2 for the base and 1/2 for the other two edges. So the angle we +want is: + +-----------------------------------------------------------+ + | 2*ARCSIN(((float)Math.sqrt(2)/2)/1) = 90.000000000000000000f 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((float)Math.sqrt(2)/(float)Math.sqrt(3)) = 109.47122063449069174f 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 = 0.6881909602355867905f + (VRp is the pentagon's vertex radio). + Face Radius For Dodecahedron + FRd = T^2 * (float)Math.sqrt((T+2)/5) / 2 = 1.1135163644116068404f +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) = 63.434948822922009981f 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 = (float)Math.sin(60)/3 = (float)Math.sqrt(3)/6 = 0.2886751345948128655f + Face Radius For Icosahedron + FRi= (3*(float)Math.sqrt(3)+(float)Math.sqrt(15))/12 = 0.7557613140761707538f +So the angle is: + +-----------------------------------------------------------+ + | 2*ARCTAN(ERt/FRi) = 41.810314895778596167f degrees | + +-----------------------------------------------------------+ + +*/ + +import java.applet.*;

+ supported by Direct3D, so these real-time rendering algorithms
+ are only really viable with OpenGL.
+
+ The program has modes for disabling the stenciling and polygon

+ * Demo of a reflective, texture-mapped surface with OpenGL.
+ * Brian Paul August 14, 1995 This file is in the public domain.
+ *
+ * Hardware texture mapping is highly recommended!
+ *
+ * The basic steps are:
+ * 1. Render the reflective object (a polygon) from the normal viewpoint,
+ * setting the stencil planes = 1.
+ * 2. Render the scene from a special viewpoint: the viewpoint which
+ * is on the opposite side of the reflective plane. Only draw where
+ * stencil = 1. This draws the objects in the reflective surface.
+ * 3. Render the scene from the original viewpoint. This draws the
+ * objects in the normal fashion. Use blending when drawing
+ * the reflective, textured surface.
+ *
+ * This is a very crude demo. It could be much better.
