lunetta Junior Member Offline Posts: 77	openGL + blur ? Jul 6th, 2005, 7:20pm   Hello all Has anyone ever achieved a "working" motion blur at p5 GL mode? I'm just failing miserably here, not sure if it's possible at this point... I found some documentation on the "Accumulation buffer" but I really don't know how to use it ( http://www.opengl.org/resources/tutorials/advanced/advanced96/node38.html) thanks!

Reply #1 - Jul 11th, 2005, 10:41pm   one thing that i've found works pretty well in some situations is the ol Code: noStroke(); fill(0, 10); rect(0, 0, width, height); trick.  to make anything in openGL work with no background calls, however, you need to clear the depth buffer: Code: gl.glClear(GL.GL_DEPTH_BUFFER_BIT); if that's not enough of a blur for you, you can just call the rect(0, 0, width, height) less often, say once every few frames.
