Yes, it is. See http://code.google.com/p/bullet/source/detail?r=2432

I see that in bFile::parseInternal, the search for 'SDNA' is in all file, not only the header of chunk: char *blenderData = mFileBuffer; int sdnaPos=0; char *tempBuffer = blenderData; for (int i=0; i<mFileLen; i++) { // looking for the data's starting position // and the start of SDNA decls if (!mDa...

Hi Erwin,

I'm sorry but the file size is about 7'7 Mb (compressed) and the size of attachment is limited to 2 Mb. Can I send you by other way?


Thanks,
Nacho.

Hi, I use serialize utility for save my btBvhTriangleMeshShape. Generally, it works. But now I've found a problem: Sometimes, when serializing btQuantizedBvh (btQuantizedBvh::serialize), the values in m_quantizedContiguousNodes .m_quantizedAabbMax[..] and m_quantizedContiguousNodes .m_quantizedAabbM...

In the btCylinderShape class, the virtual method setLocalScaling is no overwrite, and when you call it, the btConvexInternalShape::setLocalScaling is calling, that only set the m_localScaling member. Copy setLocalScaling from btCapsuleShape.h to btCylinderShape.h (for example after getRadius method)...

Hi, Should it be possible to change the draw forms of each primitive from btCollisionWorld::debugDrawObject to btIDebugDraw. Nowadays, in btCollisionWorld::debugDrawObject there are things like: case CAPSULE_SHAPE_PROXYTYPE: { const btCapsuleShape* capsuleShape = static_cast<const btCapsuleShape*>(s...

ups! Indeed, I do that mistake.

Thanks for open my eyes.
Nacho.

Hi, I see that when a capsule collide with a scaled cylinder, the distance1 in btPersistentManifold is erroneous. In btGjkPairDetector::getClosestPointsNonVirtual, before call output.addContactPoint, the data is computed correctly, but in btManifoldResult::addContactPoint, the localA and localB are ...

It's normal to see two pyramids and no, that is not the way bullet makes approximation to a sphere. It's only for render purpose.

See btIDebugDraw::drawSphere. You can derivate your own DebugDrawer class and write your sphere draw function.

In btCollisionWorld::ClosestRayResultCallback there is a member called m_collisionObject (really is member of RayResultCallback class). It tells you the collide object. btCollisionObject* pColObject=ray.m_collisionObject; When you get it, you would want know if it is a rigid body, a ghost...: if( pC...

Congratulations Erwin!!!

The LNK2005 errors are because you are using /MD and /MDd, as you say, but in Bullet lib you are using other runtime lib format (/MT or /MTd). You must use Bullet ReleaseDLL. It generates .lib, no .dll because the only diference is the "Runtime Library" option. If you need MSVCR90.dll libr...

The limits for the quaternion's values are [0,1] when it represent a rotation. The quaternion must be unitary to represent rotation: sqrt(Qx*Qx+Qy*Qy+Qz*Qz+Qw*Qw)=1 If the rotation axis (unitary) for quaternion is ax, ay, az and rotation angle around axis is angle, then, the quaternion's components ...

Thanks!
