Orion's OpenGL Info

Lecture notes on OpenGL Performance, with a focus on geometry rate. This was a 2006/04/20 guest lecture in Dr. Hartman's CS 481.

ARB_fragment_program performance in practice.

OpenGL Example Code

• Fragment shader program, using GLSL (OpenGL Shader Language, or GLslang); last uploaded 2006/04/08 (Directory, Zip, Tar-gzip)
• Fragment shader program, using GL_ARB_fragment_program and GL_ARB_vertex_program; last uploaded 2006/03 (Directory, Zip, Tar-gzip)
• Shadows via several methods: shadow maps, shadow volumes, and several flavors of projected and decal shadows (Directory, Zip, Tar-gzip)
• String processing on the graphics card, using 1D textures, fragment shader, and readback (Directory, Zip, Tar-gzip)
• Tiny OpenGL program, demonstrating geometry and mouse motion (Directory, Zip, Tar-gzip)
