I recently had an idea, but I'm not sure it's very usefull or even clever.
Here is the deal : when you texture sphere-like objects, there is a large loss of texture space due to polar tris, and distorsion. So I thought : why not model a sphere from a box, and make each side of the box cover the entire texture space. The texture would reeat six time on the sphere, but there would be less deformation and much better resolution for the texture.
While allowing a texture to tile on a flat surface is no problem, texturing a cube began to be mind boggling... It cobe posible to make sure each side of the textue would tile to with the other three, but I wasn't quite sure the result would have been worth it, so I looked for a way to make each side to tile with only one other side
Solution was the following : side A would tile with B, and C would tile with D reversed. Once smoothed, the cube turns into a sphere, and the texture tiles just fine.
Problem now : I'm pretty sure someone has thought of this before me, and I'm pretty sure this is totally useless.
Any thought ?
