I am trying to figure out how to apply a texture map to various polyhedra which I define (i.e. not using built in primatives) like the tetrahedron, octahedron, cube, icosahedron, etc.
I want to use the earth.jpg texture (Earth image) used by the Java Demo ConicWorld. I can't figure out how to define the vertex coordinates to map the rectangle of the texture image onto the polyhedra. So I thought I would try TexCoordGeneration, but I can't seem to figure out the correct parameters to use. I get multiple copies of the texture image, rather than one world image projected (wrapped) onto the polyhedron. Does anyone have an example of using a texture map to wrap around a shape once? Also, I have my polyhedra spinning like in ConicWorld. Using TexCoordGeneration, the texture *does not spin* as the polyhedron is spun. This is a cool effect, but not what I want. I want the texture to spin with the object. Any help? How do you take the rectange of the texture map and wrap it around the polyhedra to make it look like the World projected onto the polyhedra? (Particularly when the North/South Poles are not vertices of the polyhedron.)
