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 | - +-----------------------------------------------------------+ - -*/ - - -#include <stdlib.h> -#include <stdio.h> -#include <string.h> -#include <math.h> -#include <unistd.h> - -#include <directfb.h> -#include <directfbgl.h> - -#include <GL/gl.h> - - -/* the super interface */ -IDirectFB *dfb;
