A pbuffer is the GL analog of an offscreen pixmap. The spec is at http://oss.sgi.com/projects/ogl-sample/registry/SGIX/pbuffer.txt Currently we have support for pbuffers in indirect contexts only, which are contexts where the server does the rendering (in our case, in software). Direct contexts under DRI do not yet support pbuffers. Composite enables the compmgr to redirect drawing of a window from the screen to an offscreen pixmap, for normal X windows. GL windows would have to be redirected to a pbuffer in a similar fashion. > I know how Composite is implemented and I use it in our Project Looking > Glass, but my knowledge on GL and DRI is basicly as User not a developer > in DRI. as I will work in this issue I will get slowly inside DRI. > > > > ------------------------------------------------------- > This SF.Net email is sponsored by: YOU BE THE JUDGE.
