Re:

Thanks for this release!!!! Are there any examples how to use Bullet in parallel? Is it difficult to use custom portable thread system with Bullet? Because for now it seems to support only Win32, how about Win64, Mac, Linux???? Yes, several of the bullet demo apps can be switched to parallel mode v...

Interesting results. Me and a college have discussed two different ways of achieving a hierarchical broadphase utilizing SAP, mainly to solve the problem of having dense clusters of objects moving semi-coherently within a sparse world and that of additions/removals due to loading/unloading of parts ...

I've submitted a patch to Erwin which fixes the problems building in double precision mode. Hopefully it gets applied as soon as he wakes up and gets to work etc :)

So maybe something like this would fix it? void btDiscreteDynamicsWorld::removeConstraint(btTypedConstraint* constraint) { m_constraints.remove(constraint); if(constraint->getRigidBodyA()) constraint->getRigidBodyA().removeConstraintRef(constraint); if(constraint->getRigidBodyB()) constraint->getRi...

Re: [Bullet 2.53] Issues in btAlignedObjectArray.h

It depends which platform and compiler. I tried compiling it under Mac OSX/gcc, Linux gcc, and Windows Visual Studio 2005 and all work fine. Using <new> doesn't work on some of those platforms. Note we need both memcpy and placement new. So... which platform/compiler combo is broken right now? Than...

Hi, I've found two issues in btAlignedObjectArray.h in latest version (2.53) 1. Placement new is declared in header <new>, not <memory.h>. 2. reserve(int) method check capacity() < _Count twice. The first one cause a compilation error, second one just cosmetic (and possibly two cycles or so on reser...
