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);

0df4cedc3e added 'getConstraintSolver' and ability to 'reset' (set randseeds back to zero, and clear internal caches) 2007-07-27 23:54:22 +00:00

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)

82c8687881 - initialize m_unusedW to avoid some warnings. 
- added angularFactor to 'cachefriendly' constraint solver

bc3f9535ad cleaned up, removed warning under MSVC2005 (Level 4) 
Mostly related to alignment and unused variables

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

b8ce13adb1 bugfix, also convert rigidbody into solverbodies for constraints (without contact manifolds), and do additional check for validity 2007-03-17 08:29:05 +00:00

2b87104184 more solver optimizations, can be disabled using solver->setSolverMode(SOLVER_RANDMIZE_ORDER) 2007-03-17 07:59:27 +00:00

151cd4b9da prepare and added constraint solver optimizations, not activated yet. 2007-03-17 00:09:12 +00:00

adfdea5ca6 replaced #include "new.h" to #include <new> 2007-03-06 23:40:06 +00:00

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.

bf68a742cc by default, disable warmstarting, enable random ordering, 
user can override this using solver->setSolverMode(...)

7dc6aa215a some more fixes to get msvc6 happy, and constraint solver: make non-randomizing solver default 2006-11-23 02:57:38 +00:00

b07bb88a2d Added new EPA penetration depth solver 
improved gjk/minkowski sampling pd method
added original solver variant, use btSequentialImpulseConstraintSolver2
Added Pierre Terdimans PD testbed

23c64fb0db more solver experiments, randomize the order of contact points, not just manifolds 
use #defines for constants, rather then const btScalar

07873854a4 more small refactoring: some methods were still upper-case. 2006-11-03 04:32:48 +00:00
ejcoumans
4050da0e2f One of the last parts of the refactoring (hopefully), made most members of btCollisionObject protected. 
Also did some work on improving the constraint solver.

3fe3b11924 use Dispatcher in ConcaveConvexCollisionAlgorithm (so it uses the registered collision algorithm, not hardcoded convexconcave) 
improved performance of constraint solver by precalculating the cross product/impulse arm
added collision comparison code: ODE box-box, also sphere-triangle
added safety check into GJK, and an assert for AABB's that are very large
write partid/triangle index outside of GJK

2b1657b1dd Refactoring: another huge number of changes, renamed methods to start with lower-case. 2006-09-28 01:11:16 +00:00
ejcoumans
eb23bb5c0c merged most of the changes from the branch into trunk, except for COLLADA, libxml and glut glitches. 
Still need to verify to make sure no unwanted renaming is introduced.

0e04cfc806 First stage in refactoring Bullet: moved Bullet Collision and Dynamics and LinearMath into src folder, and all files in Collision Detection and Dynamics have bt prefix. 
Made all buildsystems to work again (jam, msvc, cmake)
