ewjordan Ex Member	Accumulation Buffer in OpenGL Sep 10th, 2006, 10:05am   Has anyone here had any luck getting the accumulation buffer working from within Processing?  If I recall, it's necessary to initialize OpenGL in the proper way to use this buffer, but the initialization code is behind the scenes in Processing, so I'm not exactly sure what to do. Thanks, Eric

Re: Accumulation Buffer in OpenGL Reply #1 - Sep 10th, 2006, 3:57pm   I have doneit, but it does need you to edit PgraphicsGL.java frmo the processing source, and re-build it. You'll need something like: Code: GLCapabilities capabilities = new GLCapabilities(); capabilities.setAccumRedBits(8); capabilities.setAccumGreenBits(8); capabilities.setAccumBlueBits(8); capabilities.setAccumAlphaBits(8); canvas = new GLCanvas(capabilities); Then you should be able to use the glAccum functions.
