I'm looking for suggestions on this
Say you have a cube map. You want to rotate it as efficiently as possible.
You can render the cube map, rotate the camera, and render the scene to another cube map.
But it would be faster to rotate the cubemap by operating on the texels.
I'm using D3D11, and I need to read the texels in the code (so I can't use the OpenGL "Texture Matrix"!)
