GLGraphicsOffScreen not working in linux?
Mar 19th, 2009, 9:19pm  
So I've just downloaded the great glgraphics library for processing, and all the examples run perfecty except the offscreen buffer example.  Wouldn't you know this is exactly the reason I need this library...

Has anyone else experienced problems with this in linux?

I figured out that processing 1.0.1 works fine with GLGraphicsOffScreen.  1.0.2 and 1.0.3 have broken this feature of the glgraphics library.  At least for me.

Not true...

You just have to use:
size(800, 600, GLConstants.GLGRAPHICS);

instead of:
size(800, 600, OPENGL);

Hello,

I think the problem is due to an issue with the noFill() function (http://dev.processing.org/bugs/show_bug.cgi?id=1222), and a workaround is to reset the fill state with a call to fill(0) after using noFill().

Anyways, I just uploaded a newer version of glgraphics (0.8.9.6) that includes an update Offscreen example. Download from here:

release_id=672886
