7a2a98078a Fixes for broadphase/paircache determinism.
Revert definition for ATTRIBUTE_ALIGNED16, and try to force sizeof(btSolverConstraint) by using unions with btScalar, for non-btScalar data types.
Use btAssert and not assert.
Don't access btAlignedObjectArray elements, for zero sets

2162f6663d disable help text by default in AllBulletDemos (text slows down many graphics cards)
improve CollisionDemo.cpp, show multi-contact generation using perturbation
improve ColladaConverter: add hinge/point 2 point constraint conversion support, add btScaledTriangleMeshShape support
Fix Dynamica MayaPlygin: remove 'active' flag, it has to be replaced by mass=0 for active, mass<>0 for passive
Added missing projectfiles
Fixed single-shot contact generation. it is disabled by default to improve performance
Bugfixes for character controller, thanks to John McCutchan for reporting
Constraint solver: better default settings
btDefaultAllocator: aligned allocator uses non-aligned allocator (instead of directly malloc/free)
disable memalign by default, use Bullet's aligned allocator

0754876d77 Calculate multiple contact points (for convex-convex and convex-plane) when less then 3 points exist in the persistent manifold.
Uses the normal pertubation method, described by Gino van den Bergen:  http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=4&t=288&p=888#p888
Made btRigidBody::getInvInertiaDiagLocal const, thanks to abhikp (http://code.google.com/p/bullet/issues/detail?id=183 )

bcd0f48c28 some doxygen updates, added some comments to classes, fix broken links, rename some prefix some internal GIMPACT collision structures using (for example use GIM_AABB instead of BT_AAABB),
removed obsolete btGjkEpa (it was replaced by btGjkEpa2 ages ago)

d16c1b615f pass in reference to actual contact point in cache, rather then temporary value, should fix issue 53
http://code.google.com/p/bullet/issues/detail?id=53
Thanks Alex Silverman for reporting and suggested fix
Changed addContactPoint to lowercase

fe4e81ebff - support both 32bit and 16bit indices in ColladaConverter
- added triangle part/index into btManifoldPoint

0405ce278a use size_t instead of int, for allocator
added hashtable based PairManager, thanks Pierre Terdiman and Erin Catto
improved friction in 'cachefriendly' solver
moved 'refreshcontactpoints' into collision detection, instead of solver
avoid linear search for contact manifolds, by storing an index
ignore margin for sphere shape (its entire radius is already margin)
avoid alignment checks in BVH serialization, they don't compile on 64-bit architectures
made 'bomb' box more heavy

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);

df9230327c Contribution to add optional double precision floating point support. Define BT_USE_DOUBLE_PRECISION for all involved libraries/apps. 2006-12-16 05:51:30 +00:00

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.

b14ccdaa57 rename treshold into thresold (spelling mistake)
added cr/linefeed at end of btDefaultMotionState.h

dd8297c86e refresh contact points, even when they are already persistent. needs a bit more work (a 'replacedContactCallback' where optionally the user can carry over the persistent contact data) 2006-10-30 04:51:17 +00:00

33b3ec94f1 more fixes, related to introduction of btMotionState, and using realtime timestep 2006-10-18 04:01:07 +00:00

bf847b839a another large series of changes, related to the refactoring.
CompoundShapes are tricky to manage with respect to persistent contact points and swapped order of btCollisionObjects,
During dispatch, finding an algorith etc. order can be swapped.
fixed several other issues, related to SimpleBroadphase (removing a proxy was not working)

d38549aa54 more refactoring, removed PhysicsInterface, cleaned up demos to make use of btDynamicsWorld derived classes.
removed two cached optimizations, type in btTransform and cached inverse transform (todo: test performance impact)
committed fixes that make the code adhere to 'who creates it, also destroys it'

2b1657b1dd Refactoring: another huge number of changes, renamed methods to start with lower-case. 2006-09-28 01:11:16 +00:00

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)
