Re: Bullet development updates

Great news! Bullet is a very good simulation engine. On the other hand, the documentation is lacking. I think there should be some effort to document the API and internals, and add some extra comments to the code before any new features are added. Bullet is IMHO severely undervalued and overlooked b...

Implementing proper damping in springs

I have tried to implement proper second order damping in the spring constraint. For linear motion damping the following code works well: inline btVector3 get_linear_velocity(double time) { btVector3 vel= (m_calculatedLinearDiff-old_pos1)/time; return vel; } for(i = 0; i < 3; i++) { if(m_springEnable...

Hello, I am trying to define a slider constraint along a line defined by two points, using the btGeneric6DofConstraint method. So given point A and point B, the body should move in the straight line connecting the points. Has anyone solved this problem before? The documentation on the subject is pre...
