Real-Time Physics Simulation Forum

I noticed a ways back that the compound algorithm has a few places where it gets pretty slow, and I had to make some pretty major modifications to get it to perform better. What platform are you working on? If you can send me some sort of performance capture I might be able to help.

Has anybody seen any strange popping issues between a cylinder and triangle? I have a strange issue where ever so often a cylinder collision will cause some pretty strange forces, but haven't been able to track it down. Disabling the cylinder in the rigid body seems to get rid of the issue though..

Hey Erwin,

I am having a pretty strange crash that seems to pop up in a few places on the 360. I wasn't sure if you had access to a 360 dev kit for duplication purposes, so I thought I would ask that first. I have everything you should need to reproduce if you do.

Hey Everyone, I have just upgraded to 2.74 beta, and discovered that the constraints have vastly improved, thanks Roman! Unfortunately, I do have one problem that I am not quite sure how to approach. I have a moving object (vehicle) with hinge constraints attached to various parts (door, hood, trunk...

Hey Erwin, When I posted earlier, I said that I managed to get the simulation deterministic, but I said that things were not colliding so well. Well, I finally managed to track down the issue, or at least the source causing the issue. Basically, if I go back to the previous revision of the btCompoun...

Well, good news and bad news. Good news is that this thing is definitely Deterministic now. I had to upgrade to 2.73, as the adding of the clear didn't fix it alone (I was trying to be lazy). Bad news is, things aren't colliding so well. Looks like the broadphase is screwy for some reason, as they s...

We are working on a game that requires the use of replays. We have been working with ODE for several years now, and the replays work fine, so the internal game code is solid, but for some reason, I can not seem to get bullet to be deterministic. I have attempted everything that I can think of at thi...
