gpu's arent just good for vision and computation - some clever folks have started using them for games as well. ;) har har linux-games.net

7 Years of Graphics Card History

Page design based on Blosxom (which was used originally before the move to sourceforge).

Framebuffer Objects

Framebuffer objects can be used to provide a render-to-texture functionality on Linux systems. This will hopefully save the time spend executing a CopyTexSubImage2D() when the results from a fragment program need to be re-used as a texture. FBO's instead allow rendering to a texture.

Being able to 'feedback' the results to another rendering pass quickly is important to achieve best GPU processing speed. Since I wasn't able to easily find any simple programs to demonstrate this, I hacked one out that seems to work, and I thought I'd provide it in case others might find it instructive too.

Please email me (fungja [[at]] eyetap.org) if anything is amiss.

Make sure you have the newest NVIDIA drivers, and that the glxinfo output contains the string "GL_EXT_framebuffer_object"

Here's a link to a downloadable C file

Compile it with something like :

gcc simpleFBO.c -lglut

Update: 19Feb2008: Added glutInit() calls.

Multiple Render Targets with Render to texture functionality

This is basic example where a fragment program is used to render to two different textures in a single pass, an example of multiple rendering targets achieved using the framebuffer object extension. See top of file comments for more information.

LInk to accompanying Cg Fragment Shader Program

Compile it with:

gcc multiFBO.c -lglut -lCg -lpthread -lCgGL

Update: 19Feb2008: Added glutInit() calls.
