Environment-Mapped Bump Mapping (EMBM) effect summary

DirectX implements bump mapping using a technique best described as "environment-map bump mapping". This method can only be used on systems with hardware that specifically supports it. In DirectX 6, bump mapping is implemented using two textures (not including the object’s base texture). The first is a bump map which contains slope information (you can think of it as a height differential map), rather than height information, as is the case with the embossing method. (The bump map is generated by comparing adjacent texels in the height map). Hardware that supports DirectX 6 bump mapping uses these values to perturb the texel coordinates used in the lookup into a second texture (as opposed to using the data to alter the polygon’s normals). The second texture is an environment map, which is rendered onto the original polygon using these perturbed UV coordinates.[1] Matrox Millennium G400 was the first commercially available 3D accelerator to support Environment-Mapped Bump Mapping.[2][3]
