graps : capture OpenGL Frames
Tuesday, May 2nd, 2006graps is a tool for grabing frames from openGL application, without editing the application. graps can be used for making video from an opengl application. graps can also be useful for monitoring fps of opengl application.
graps writes the glReadPixel data to file on each glXSwapBuffers call. graps uses the power of LD_PRELOAD to run without modifying the application.
graps is dirty fraps alternative for screen and realtime video capturing and fps monitoring ( hence benchmarking ).
graps can be downloaded from here. See readme.txt for help.
