hello everybody, can anyone tell me how to access the pbuffer under mac os x. i can’t find a proper extension… (i’m using a geforce4 ti)
thanx in advance.
What’s a PBuffer?
If you create a second context (sharing textures, display lists, &c with your first), attach that context to a window you never show (to get acceleration), you can then texture from the second context to the first using aglSurfaceTexture() or -[NSOpenGLContext createTexture:fromView:internalFormat:]
A GLX version check using glXQueryVersion returned 1.2 which does not support PBuffers (I’m using Mac OS X 10.2.4). However, looking into glxtokens.h I noticed that GLX_VERSION_1_3 is defined (1.3 is required for PBuffers support). I’m confused. What is going on?
I was assuming that pinsky was using the standard OpenGL APIs, not X11.
