Collision Lags

Post by JanK »

Hi there

Although Bullet 2.76 does solve the sliding issues, i still get the lags when a rigid-body that is quite fast moving collides with something else (static geometry in my case). Erwin already mentioned that this is the case due to velocity clamping (or something like that) when continuous collision is enabled.

To be more precise: The rigid-body (sphere) moves fast, collides with a wall, it then suddenly stops entirely for a few frames (the app does not halt, it's only the rb that stops), then it bounces back off the wall and continues properly (sliding along the wall, etc.).

This is a most annoying artifact in my app, because the sphere is used for the camera, which means the user notices it all the time.

Is there any plan to resolve this issue in the near future?

Thanks,
Jan.
