e755d1ed4e added some comments, to clarify unit-test/brute force implementations. 2007-11-02 01:14:29 +00:00

ea3dfb4ca3 made 'calculateLocalInertia' const, thanks to cgripeos, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1514
- applied a large patch to remove warnings
Thanks to Enrico, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1568
- removed SSE includes, added #incude <string.h> for memset in Extras/quickstep, thanks Eternl Knight
- disabled 16-byte alignement on btQuadWord class, it causes problems under PS3 Linux. Need to check out why.

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

08d036afc7 multi-threading improvements: optionally use software caching (IBM/PS3), move some code from cpp to header to inline. 2007-09-20 22:42:56 +00:00

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);

c1250cd26a Planar triangle meshes with zero extends (in any direction) could cause quantization failures (division by zero).
Added a positive value to quantization AABB (doesn't affect performance).

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

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

7adc0742e3 Added demo code that show recursive traversal on tree data that doesn't have explicit left/right child pointers.
Can also be used as starting point for tree versus tree.

4685f6acc8 Added a refit to the quantized stackless tree, with updated ConcaveDemo. 2007-03-21 02:45:43 +00:00

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

ca973e9322 Fixed AABB tree building, which failed for certain large triangle meshes due to stack overflow.
Now it has a safer check for unbalanced tree, and forces them to be balanced.

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

bf591b44ec Replaced most STL std::vector with btAlignedObjectArray.
Same interface but less features (push_back, pop_back, clear, size, [] etc).
To prepare for SIMD/SSE code: Added 		#define ATTRIBUTE_ALIGNED16(a) __declspec(align(16)) a

323a1046fd Cleaned up/simplified construction of a btRigidBody
Fixed memoryleak in btOptimizedBvh (delete []m_contiguousNodes;)
Changed DemoApplication::localCreateRigidBody, so it adds the rigidbody to the btDynamicsWorld.
Added check for duplicate objects in world when adding.
Added assert to prevent setLinearVelocity on static rigidbodies
Added btCollisionFilterGroups to btBroadphaseProxy
removed duplicate 'btBroadphaseProxy*	m_broadphaseProxy;' in btRigidBody

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)
