Here are my notes for today's lecture on making surfaces bumpy.
Updated: here are some demos of bump mapping:
- Nvidia has a nice demo of parallax mapping.
- This Nvidia page has several bump mapping demos, including normal and parallax mapping.
- Nvdia references this displacement mapping demo.
- Here is a simple normal mapping demo.
- This gamedev.net CG demo lets you compare normal mapping to texture differencing hacks.
Also, Nvidia has these nice discussions:
Best,
Ben
