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 References: Cel-Shading by Sami "MENTAL" Hamlaoui. From www.gamedev.net 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.
