Jean Pierre Charalambos recently released the version 1.0 of his Proscene library. Proscene is a Processing library that handles camera and coordinate system transformations in order to simplify the creation of interactive 3D scenes. In principle, Proscene can use any 3D renderer in Processing (P3D, OPENGL, GLGraphics), but we have been working together to allow for a better integration of Proscene and GLGraphics, in particular for offscreen rendering.

Integrating Proscene and GLGraphics 4 comments
GLGraphics update compatible with Processing 0148+ Leave a comment
The opengl rendering/threading mode in Processing received some major changes in version 0148. These changes are incompatible with old releases of GLGraphics, but this is solved in the latest release, 0.8.2. This release adds a new class, GLGraphicsOffScreen, which implements off-screen rendering to texture. The downloads are available here.
Another advantage of 0.8.2 is that there is no more need of installing a hacked version of opengl.jar, so things like applets and exported applications that use glgraphics should work fine.
Off-screen fixes for ATI on OSX Leave a comment
A few days ago some people noted that the off-screen mode of the GLGraphics object would not work on ATI cards (see the thread in the Processing forum). A new release of the GLGraphics library (0.8.1) that fixes this issue is available for download here.
First of all, it seems to be a problem related to the opengl drivers on OSX, since I tested the off-screen rendering on a ATI 1550 on Windows XP (using catalyst drivers 6.7), and worked ok.
