Simulation with a lot of objects
Posted: Mon Jul 27, 2015 11:55 am
Hi All
What is a best way(s) to handle scenes with a lot (100K and more) of objects? Like a rain, snowblind, falling sand etc. I realize such simulation can take a significant time, it's not a catastrophe. Clear that I need to use a simplest shapes (such as sphere, cube) and, most probably, disable self-collisions. But are there more things to make it faster and to reduce RAM using?
- is it a rational idea to convert slept dynamic bodies into a static mesh(es)?
- can I use a very simplified/primitive collision detection, for example just cast a ray along speed vector? If so how?
- other ways/secrets that I don't know?
Thx
