Re: performance of collisions of 'voxel' shapes

There's only a single unit-sized cube shape reused everywhere. Once I make a proper benchmark I can compare any possible effect it can have. Now the "VoxShape" sounds interesting. I've found the "Voxels collision" topic on this forum: https://pybullet.org/Bullet/phpBB3/viewtopic.php?t=11358 but as I...

Re: performance of collisions of 'voxel' shapes

Hi, thanks for suggestions. Yes, i'll definitely optimize the shapes. However I would expect the number of shapes to go lower a couple of times only, at least with the naive implementation of optimization that I'll be able to come up with. Still, it's puzzling for me that with as little cubes as I h...

performance of collisions of 'voxel' shapes

Hi, I have some rigid bodies each with collision shape consisting of many cubes (in compound shape) looking like, say, chunks of Minecraft-like ground. When these objects start to collide I get heavy performance drops (below 1FPS). This happens even when there are only a few (<10) such objects (thou...
