optimize collisions in a particle system
Apr 16 2014 | 3:09 pm
I need to do a particle system with about 800 spheres. The patch runs quite well while collisions are off (55 fps), but I soon as I turn it on, it slows quite a lot (13 fps).
I need to optimize my patch to make it run smoothly.
I don't need to detect the collisions between each sphere, I just need the collisions between the spheres and the 3 walls. Is there a way to avoid the patch to calculate the collisions between the spheres of the jit.phys.multiple? It would save a lot of CPU I guess...
cheers

I just don't need the collisions information about them colliding between them. So, I guess, I'm going to need to look to another way to do it as you suggested me in that post… https://cycling74.com/forums/particles-ofprocessing-vs-max6
