erwin.coumans 49a0b479c6 Switch off an optimization by default, to avoid support burden: update all objects AABBs and not just the active objects. 
Call world->setForceUpdateAllAabbs( false) to re-enable the optimization: it will only update active objects (skipping static geometry)

erwin.coumans 0ada7cbb1e Fix in btGjkPairDetector, possibly causing a floating point overflow 
Thanks Ole for the report and suggested fix:

Applied Character/btKinematicCharacterController.cpp patch:
Thanks Thomas for the patch!

 - added a normalizedDirection member variable.  This is
     slightly more efficient than recalculating the normalized
     direction every simulation step.

 - I overloaded the m_walkDirection member variable to hold
     either the walkDirection or the Velocity, and used a boolean
     flag to determine which behavior was required.

 - The normalization behavior seemed custom, and I needed it
     twice, so I moved it to a static helper method.

 - I added the setVelocityForTimeInterval() method to the
     base interface class.  This to me is the scariest change
     since people inheriting from it will need to make changes
     (if only to add an empty function).

erwin.coumans badf723257 Replace all hardcoded 1e30(f) by BT_LARGE_FLOAT, defined in btScalar.h as 1e18(f) so that its square still fits in FLT_MAX

erwin.coumans 4ad21d36f9 some fixes in build systems 2009-05-22 19:24:20 +00:00
erwin.coumans fb6146f0be Added MiniCL, a limited subset of OpenCL, the open standard for parallel programming of heterogeneous systems. 
MiniCL includes a cross-platform run-time frontend based on pthreads, Win32 Threads, or libspe2 for Cell SPU.
It is there, to bridge the gap until OpenCL is more widely available.

erwin.coumans 2f1014268b + Internal improvements for collision shapes 
1) add AabbCaching versions of btPolyhedralConvexShape and btMultiSphereShape (this speeds up btMultiSphereShape 'getAabb', and reduces size of btBoxShape)
2) btCylinderShape doesn't derive from btBoxShape anymore
+ Minor fixes in drawing for btMultiSphereShape, btBoxShape.
+ Don't re-generate btDebugFont every frame
+ Disabled velocity prediction for btDbvtBroadphase. Previous default can be restored using btDbvtBroadphase->setVelocityPrediction(1./2.);
