We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I have a for loop that I am running on the CPU to draw thousands of 2D circles per frame, using ellipse(). Could I pass the locations of all of these ellipses to a shader somehow and see a good performance increase?
It seems like this should be easy to do with a frag shader but I am pretty inexperienced and can't find any examples of doing anything similar in processing.
edit: I think the PixelFlow customParticles example has everything, just not very straightforward adapting it
