Why would you wanna do that? Then there's no point in using a pbuffer.

There are number of uses of glCopyTexImage2D with pbuffers. Using textures biger then your viewport and limitations to number of pbuffers are just two of them.

Just sounded to me, like he wanted to render directly to the pbuffer... Avoiding gopypixels.
But thanks for the info :)

A 3D texture contains information in three dimensions as opposed to two. The addition of the third dimension allows developers access to a depth component of texture information, as well as width and height. NVIDIA’s 3D textures enables developer to think in new ways when texturing objects.
