After some investigation, I think for my purpose I can simply make a modified version of PGraphicsGL to include abilities to set up the GLCapabilities and make calls to glDrawBuffer().

I may be interested in helping you sort out some of those issues though ... have you thought of opening this initiative as a collaborative project?

Hopefully I'll be able to get it to a stage where the changes I've made make sense. But it's a bit of a shambles at the moment, and I'd be embarrased for it to be public in the state it is Smiley

My OPENGL renderer is nearly finnished, it passes all the commands from processing directly to OPENGL, i also included a shape object for simple use of display lists. It seems that everything is working fine so far, but I am looking on different things to increase performance. So I put the primitives sphere and box in display lists for example. I hope to release the stuff within in the next two weeks.

I have recoded more methods of the renderer. For example pixel operations like copy and blend are now done by opengl, like ben already recommended in the source code comments. The results of the blend look a bit different to that of P3D but work much faster.

The next step could be to implement the filter methods as OPENGL pixel shader, I started to have a look an that but any help would be appreciated.

To release the renderer I have to wait for the new processingversion, as I need access to some field of PGraphics that are currently private.

Hi Ben

I need all the color attributes for tint, fill and stroke to be set to protected. Maybe you have a better idea, but to me it seems to be the best way of colorhandling for my renderer.

cheers christian

actually, those have already been fixed for the next release, though i wouldn't use the version that's in subversion just yet, as naming for some of the classes are changing, and we haven't decided on the final names yet.

yepp I recognized that, so what are you plans for the new version. Any release date? Are there a lot of changes with the renderers?
