PBuffer Rendering
+ +
+Basically, FBconfigs and PBuffers allow you to do off-screen rendering +with OpenGL. The OSMesa interface does basically the same thing, but +fbconfigs and pbuffers are supported by more vendors. +
+ +
+PBuffers are getting more use nowadays, though they've actually been +around for a long time on IRIX systems and other workstations. +
+ +
+The +GL_SGIX_fbconfig +and + +GL_SGIX_pbuffer extensions describe the functionality. +More recently, these extensions have been promoted to ARB extensions (on +Windows at least). +
+ +
+The Mesa/progs/xdemos/ directory has some useful code for working +with pbuffers: +
+ +
- pbinfo.c - like glxinfo, it prints a list of available + fbconfigs and whether each supports pbuffers. +
- pbutil.c - a few utility functions for dealing with + fbconfigs and pbuffers. +
- pbdemo.c - a demonstration of off-screen rendering with pbuffers. +
+ +
+Mesa 4.1 and later support GL_SGIX_fbconfig and GL_SGIX_pbuffer (software +rendering only). +
