Real-Time Physics Simulation Forum

Hi: I'm looking for some serialization from bullet to blender etc. I have my own rigid body dynamics controller implemented in bullet application (works in every step simulation), and I want to make the animation looks better than just a debugger displays. I think that the easiest way to achieve the...

Hello. While setting joint configuration, I have come up with a question... Can I fix the joint translation and make it won't move? Because when I setup a ball joint, and gave some forces, two rigid bodies eventually fell apart when forces were increased to certain magnitude. Small discrepancy is ex...

Hi! I had trouble with the friction. Previously, I could not get the lateral values (post: http://bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=9&t=7906 ) Examining through btSequentialImpulseConstraintSolver , I understood how to update friction values. It's interesting to learn how these var...

With several tests, I found to get a lateral impulse data. All I need to do is adding flags into btContactSolverInfo.h: SOLVER_USE_FRICTION_WARMSTARTING SOLVER_USE_2_FRICTION_DIRECTIONS Second flag is for preventing crash due to the array size. Still, I'm not sure what these 2 direction means.. is t...

Hi. I'm testing some collision objects using Bullet, and there's a problem I can't get now. I want to know about the contact force applied on the rigid body. Found btManifoldPoint has m_appliedImpulse, so I can get the applied Impulse on the normal contact direction of two rigid bodies. The friction...
