Hi,
some questions about glTexGen*. You pass for each texture coord dimension a reference plane which is the yz-plane for the s-coord and so on. In GL_OBJECT_LINEAR mode then for every vertex in world-space the distance to each reference plane is computed and based on this distance the texture coord is assigned. Right?
But what is going on in GL_EYE_LINEAR? Is the near clipping plane the eye-plane?
