Performance differences with POINTS between 1.11 and 2.0

Let me point out that in the examples that do collision detection, they are “lossy” in that only the last particle in a texture grid location is stored. If A and B are in the same grid cell, A will write its id, then B will overwrite it. When they resolve their collision, A will see B in its cell and bounce off of it, but B will only see itself and so not bounce.

Oh, that’s how that works! I did decipher part of the the grid stuff but I didn’t quite understand the id stuff. That is pretty clever

Thank you for those documentation links, I will start going through them. p5 1.11 uses WEBGL 1, right? Does p5 2.0 use WEBGL 2? Is there a big difference between the two?
