A Variation on Lightmaps, Gloss Mapping
Texture controls specular contribution
- Lightmaps modulates diffuse lighting
- Gloss mapping modulates specular lighting
- Examples
- Shallow puddles of water on a floor
- A pencil’s shiny metal and glossy yellow paint versus its non-glossy pink eraser
- Glossiness can be hidden in the alpha component of textures and the frame buffer.
