Does anyone know detailed information about how to build amesh by yourself (including mapping data).
Or a little example of building a box.
Mesh data ?
Here is a small sample, I modified this from some code from Danilo.
Strictly speaking you'd just need 8 vertices to make a cube, but for texturing reasons I made a 14 one.
It also took me a while to realize how normals work. But after some experimenting I understand now
Hope this helps.
