Bump Mapping on the ATI Rage128 with
OpenGL
|
|
|
The Rage128Bump sample program uses multitexturing via ARB_multitexture and EXT_texture_env_combine to perform the popular emboss style of bump mapping. This example program uses a bump mapped sphere from Blinn's original paper on bump mapping.

Building and Running Rage128Bump
In order to build Rage128Bump, you must have a gl.h file that contains the necessary defines for both the ARB_Multitexture extension and the Texture_Env_Combine extension. Likewise to run the app you must have OpenGL drivers that implement these extensions. Please see the page Building OpenGL Samples for more information on this and other general information.
