I want my cube maps move with the camera position, not with the camera rotation, like in this demo:
How do I do this in OpenGL? If the camera position is x,y,z, what do I do to the texture matrix to make my cube map move? (I am using GL_REFLECTION_MAP).
-Most explanations I read say to rotate the texture matrix by the camera rotation. This makes no sense. The reflection should only change with position, not camera angle.
-I am not using a modelview matrix, really, because I am rendering static brush geometry, i.e. the BSP walls and floor of a map.
-Play the "Chrome" map in UT2004 and look at the walls. THAT's what I want. Or just download the demo above.
