121fd7808e Changed BulletMultiThreaded Thread Support to be passed in, rather then global 'Win32ThreadSupport'/'Libspe2ThreadSupport' etc. 
This allows developer to hookup Bullet to a custom task scheduler, by deriving from btThreadSupportInterface.

5c80ff1f7d improved performance by adding constructors to btTransform/btMatrix3x3 to avoid conversions, compoundshape returns const references (instead of duplicate objects) 
Thanks Marten Svanfeldt, Starbreeze Studios

59cb275c9c basic support for height fields. They are producing temporary triangles, similar to the plane shape. 
VehicleDemo demonstrates heightfield support.

cf2337ed7b - Fixed a bug in btAxisSweep3 (sweep and prune) related to object removal. Only showed up when at least one btStaticPlaneShape was inserted. 
Thanks tbp for more details on reproducing case.
- Fixed issue with full 32bit integers in btAxisSweep3 (define BP_USE_FIXEDPOINT_INT_32), it used only 65536 for quantization, it should use full integer space (0xffffffff)
- Added 'getForwardVector' and getCurrentSpeedKmHour utility functions to btRaycastVehicle
- Fixed local scaling issues (btConvexTriangleMeshShape, btBvhTriangleMeshShape, removed scaling from btMatrix3x3). Thanks Volker for reporting!
- Added second filename search, so that starting BspDemo and ConvexDecompositionDemo from within Visual Studio (without setting the starting path) still works

ceee6d7e14 renamed ${OPENGL_glU_LIBRARY} into ${OPENGL_glu_LIBRARY}

2db8bfa3d6 Fix (needs more testing) in btRigidBody::setCenterOfMassTransform, assign m_interpolationWorldTransform = xform; instead of m_worldTransform; 
Thanks Jay for reporting
Added braking capability to btRaycastVehicle, see Bullet/Demos/VehicleDemo/VehicleDemo.cpp
Added glutKeyboardUpFunc, for vehicle demo (keep accelerating/breaking, until key released/UP). Hope this is compatible with most GLUT implementations.

897d1491fa enable aabb compression in ColladaDemo btTriangleMesh. 2007-03-12 23:20:41 +00:00
ejcoumans
054d672592 - removed STL from the Bullet library: replace std::vector by btAlignedObjectArray. Also removed the std::set for overlapping pair set, and turned it into an overlapping pair array. The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal). 
- added heap sort and binary search/linear search to btAlignedObjectArray
- fixed wrong cast, thanks Hamstray, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=1015

b73900bc60 Improved performance of convex collision shapes, cache local AABB instead of recomputation. This fixes issue with very slow performance in larger .bsp levels. 
Moved some asserts into 'btFullAssert', which is disabled by default (see btScalar.h to enable them). This is to speed-up debugging.

e610598d33 - Added compressed/quantized AABB tree, 16 bytes per node, while supporting 32-bit (triangle) indices. Should be faster and smaller then original version (quantized aabb check is done in integer space) 
Original aabb nodes are 44 bytes (with full floating point precision and additional part index)
- added meter-unit scaling support in ColladaConverter.cpp

581468ceec Added btCapsuleShape. This could already be simulated by simply adding 2 spheres to the btMultiSphereShape, but this was bad documented/unknown. 
For tapered capsules, you can still use btMultiSphereShape, just pass 2 spheres with different radius.

e9b21e21a6 Pathnames between #include files that are intended to be used within application code should not depend on the paths to the subdirectories being known to the compiler because this will not always be the case when an end-user includes your headers.

bf591b44ec Replaced most STL std::vector with btAlignedObjectArray. 
Same interface but less features (push_back, pop_back, clear, size, [] etc).

b6d1b4c94e Added btNearCallback. This is similar to Open Dynamics Engine (ODE) dNearCallback, but important differences: 
- contact points are persistent (lifetime more then one frame, for warmstarting/incremental contact point management)
- continuous collision detection, time of impact
Added btRigidBody::isInWorld(), returns true if btRigidBody is inside a btCollisionWorld/btDynamicsWorld derived class
Added angularFactor to btRigidbody, this helps some character control (no angular impulse applied)

* Unused variables.
* Missing newlines at ends of #included files.
* signed int loop variables where the termination condition is an unsigned 'get number of' function.
* 'NULL' used inappropriately for an integer or character constant (NULL is a pointer)
* abstract base classes with no virtual destructor.
* Floating point constants used to initialise integer variables.

Did some tests with 3000 rigidbodies, works much smoother now :)
