Posted: October 11, 1999 Written by: Dan "Tweak Monkey" Kennedy Cube Enivronment Mapping Another unique feature of the GeForce 256 is cube enivornment mapping. This is actually fully supported by OpenGL and by DirectX7, so you can relax and know that games will use it in the future. The goal in using cube environment mapping is to deliver perfect, real-time reflections and specular lighting. What's wrong with the image below?  The reflection looks fine except the viewpoint. The reflection in the sphere actually shows the pool that it is blocking. This is impossible in real life, so something is wrong. The addition of cube environment mapping removes such issues and also adds real time reflections/specular lighting for free, meaning there is virtually no real performance loss. What's better about cube environment mapping is that they take less memory and are actually somewhat easier to incorporate than conventional methods. I will have more screenshots of cube environment mapping in a few weeks. Stay tuned for more information. Here are some of the developers that have announced they will support cube environment mapping and other GeForce 256 features:
