Re: ConeTwist Constraint: issues and improvements

Nice to see that someone got around to improve on my old constraint, I quit the gaming industry before I hade the chance to do so. Anyways, Before I quit was planning to implement a swing-twist decomposition for the conetwist constraint but in a slightly different manner to what you are describing. ...

Re: How to make a correct limbo-hinge? ( door-wall example )

Dragonlord, Since this is an open-source project you are more than welcome to contribute. These are obviously missing features/bugs and your points are very valid. I assume you already noticed that 90.0f*PI doesn't make any sense for the joint limits. Either one adds a constructor which takes the B-...

Hey Binofet, My guess is that there still are bugs in the code, I'll try to fix them once I've investigated more. Anyways, some return questions: Are you initializing the Hinge Constraint by feeding it a proper frame (btTransform) for each body? The constructor which takes axii as input should mainl...

Network physics

Can anyone here direct me to sources of information on network physics? So far I've come up empty handed and this is indeed a very challenging problem. One setup is to have a central server to handle all simulation, but what if one wants to have multiple clients simulating a local set of rb:s and th...

Maybe it's already been implied in the thread, but there is also the closed form integration technique for quaternions. See for instance htttp://graphics.stanford.edu/~rachellw/files/articulated.pdf. Page 4, eq 1.

Don't remember the exat source of it, think it might be NASA?
