11cfbc489d upgraded version, fixed compiling issues 2007-09-10 01:25:09 +00:00
ejcoumans
b054f375bc - Added serialization to btBvhTriangleMeshShape/btOptimizedBvh. See ConcaveDemo for example usage. 
- added bt32BitAxisSweep3, which co-exists without recompilation, using template class. This broadphase is recommended for large worlds with many objects (> 16384), until btMultiSwap is finished.
- Fixed some recent issues in Bullet 2.57 related to compound (thanks Proctoid) and memory allocations

87df3d0f32 Based on feedback from another professional game company, there are several improvements, including some API change... 
Some dynamic memory allocations have been replace by pool allocation or stack allocations.
quantized aabb versus quantized aabb overlap check is made branch-free (helps a lot on consoles PS3/XBox 360)
Collision algorithms are now created through a new btDefaultCollisionConfiguration, to decouple dependency (this is the API change):
Example:
	btDefaultCollisionConfiguration* collisionConfiguration = new btDefaultCollisionConfiguration();
	m_dispatcher = new	btCollisionDispatcher(collisionConfiguration);

ec22825e65 added parallel solver (work in progress) and made modifications to demo/constraints to allow for getting the type without using virtual functions (needed on CELL SPU processors) 2007-08-12 17:27:33 +00:00

b6cd61a5e1 preparation for multi SAP broadphase 2007-08-03 01:39:36 +00:00
ejcoumans
1f7646f72a Refactoring to enable multi SAP broadphase. 
This was already planned, and Pierre Terdiman recent thread motivated me to decouple the paircache from the sweep and prune.

ejcoumans
177b6f5ce2 Added btUniformScalingShape (including support for debug rendering etc) 
This allows to re-use a convex shape, while each instance can re-scale it (with a uniform scalar factor)

2d038c8f49 added RagdollDemo (needs a bit more work, the initial constraint setup 'flips') 2007-07-27 20:23:54 +00:00
ejcoumans
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

5f8873c339 support diamondsubdivision (thanks Jay for contribution) 
support user-defined broadphase collision filtering (thanks Marten)
make sure btSimpeDynamicsWorld doesn't use cache friendly optimization in the solver (added an assert, and updated BasicDemo)

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} 
This allows MinGW32/MSYS makefiles (using cmake -G "MINGW Makefiles") to build (used to have a link error against gluLookAt etc)

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.

9546633ade Added 'cache friendly' tree traversal format, and traversal. Array of subtrees with specified maximum size. This is useful to fit tree traversals on SPU. 2007-03-27 21:02:45 +00:00

c1a54d9edc Attempts to improve performance. Not much gain yet, but good to experiment what has effect and what hasn't.

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
