Program 11 – Environment mapped bump mapping (EMBM)
20.02.2004
EMBM is mapping environment to mirror bump surface. It is advanced method of environment mapping. It isn’t computed per vertex as sphere or cube mapping, but this is computed per pixel. This uses reading from texture depended on other texture. First texture is sphere map texture, second texture is bump map texture.
Request: operator BUMPENVMAP (bump environment map) and 3 texture units for multitexture.
