Bump map in direct3D

Recommended Posts

Depending on your target card, you may need to convert the bump map to a normal map. Then, use dot product formula to your advantage in lighting, and for bumped environment mapping, offset the envmap texture coordinates appropriately per texel with the normalmap.

If this is not clear, then i suggest you study some more theory behind bumpmapping.

Kind rgds,
