Description: This program displays a torus rendered with "cartoon lighting". The dot product between the normal and light vector is performed in object space, and used as a lookup into a 1D texture with "sharp lighting" values. The dot product is computed manually, or using a vertex program. The back faces are then drawn in wireframe mode to create an outline.
The download for this project contains two separate versions, one using NV_vertex_program to perform the lighting calculations and one using ARB_vertex_program.
Requirements:
EXT_compiled_vertex_array
EXT_texture_edge_clamp
Required for vertex program calculations:
NV_vertex_program/ARB_vertex_program

Keys:
F1 - Take a screenshot
Escape - Quit
1 - Use manual cartoon lighting calculations
2 - Use vertex program
Up Arrow- Increase outline width
Down Arrow- Decrease outline width
Use the mouse to spin the object.
