There is a typo in Extras/BulletMultiThreaded/SpuParallelSolver.cpp:31:
Code: Select all
#include "LinearMath/btQuickProf.h"
when it should be
Code: Select all
#include "LinearMath/btQuickprof.h"
Note the small 'p'-character in the second version. Or rename the mentioned header file
Bug in convexTest stuff...

The convexTest hits a triangle mesh, the m_hitNormalLocal in the convexResult is already in world space, but the code in AddSingleResult() is transforming it again thinking it's not in worldspace (the bool param normalInWorldSpace is false).

I found this bug too. Cost me 2 days debug my program, and finally found that's a bug in Bullet. ( 2.67Alpha has this bug too.)
Code: Select all
bool btContinuousConvexCollision::calcTimeOfImpact(
const btTransform& fromA,
const btTransform& toA,
const btTransform& fromB,
const btTransform& toB,
CastResult& result)
{
....
n = pointCollector.m_normalOnBInWorld;
....
result.m_normal = n;
}
the normal is in world, but btCollisionWorld::objectQuerySingle call addsingleresult with wrong parameter when collisionShape->isConcave:
Code: Select all
bool normalInWorldSpace = false;
return m_resultCallback->AddSingleResult(convexResult,normalInWorldSpace);
btw: I think btCollisionWorld::objectQuerySingle's code is copied from btCollisionWorld::rayTestSingle. But they have little different make this bug.

Thanks for the bug report. A fix has been committed to SVN.
