Quick question, to get started with GLSL do I first need to know about pbuffers? Do GLSL programs require using a pbuffer? Thanks. [Edited by - sjf on January 20, 2006 4:18:00 PM]

No, you don't need it.
The GLSLang allows you to use openGL "in the same way" (replacing the common fixed operations, like vertex transformation, light & color calculation, etc) that you use with the fixed function pipeline, so if you need to programming an effect that requires pixel-bufers such HDR then you need to implement it.

i wouldnt recommend using the pbuffer for HDR. its way to slow. if you have support for it, i would use FBOs. they are renderable targets on the graphics cards which can be used similarly to image buffers.
