62103c94de fixed growing of hash table, to avoid hard limit on overlapping pairs 2007-10-12 05:53:27 +00:00
ejcoumans
eff4fe8ec8 more work on hashed pairmanager. growing doesn't work yet, so need to allocate enough room for the overlapping pairs in advance. 
boxbox reports contact point in B, rather then average point
box, cylinder use halfextents corrected for scaling and margin. made the margin in this halfextents explicit in the 'getHalfExtentsWithMargin' and 'getHalfExtentsWithoutMargin'
integrated changed for ODE quickstep solver
replaced inline with SIMD_FORCE_INLINE
some minor optimizations in the btSequentialImpulseConstraintSolver

added cone drawing (for X,Y,Z cones)

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

23a197b3dc add alignment for broadphase proxy/handle. need to benchmark this, and check it doesn't degrade the performance on other platforms. Otherwise make it conditional only when USE_LIBSPE2 is defined 2007-10-03 00:41:55 +00:00

1d43b5ebae changed default stack size to 2 MB. This is still overly conservative probably. Need some deeper investigation on default memory sizes... 2007-09-30 04:43:34 +00:00

a38de566c6 make sure aligned structures/classes use the btAlignedAlloc/btAlignedFree, by overriding the operator new/delete for that struct/class.

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);
 2007-09-08 05:40:01 +00:00
ejcoumans
30b1887f40 added configuration files for collision detection. 
this allows to use different collision algorithms by default, and avoid linkage issues.

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.

5279f9e129 BulletMultiThreaded (SPU/multi-core): added compound shape support and concave-convex (swapped case). Thanks to Marten Svanfeldt 2007-08-02 20:16:58 +00:00

871521dd6a updated CMake build for btUniformScalingShape/btConvexInternalShape 2007-07-28 21:31:32 +00:00
ejcoumans
38b7f474c3 Added better support for btUniformScalingShape, by moving some data that is not shared from btConvexShape to btConvexInternalShape. This reduces the sizeof btUniformScalingShape to 16 bytes (from 64). 
This is good when having lots of re-used shapes with different sizes.

Convex shapes will need to derive from btConvexInternalShape (which is a subclass of btConvexShape). We could have renamed btConvexShape to 'btConvexShapeInterface' (can still do that later)
 2007-07-28 21:10:21 +00:00
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)

a1fabc4b91 ray hitnormal is already in worldspace for convex objects, but not for trianglemeshes (ray is transformed in local space) 2007-07-27 23:52:33 +00:00

bf967a458a applied patches from Marten (Starbreeze) for per-rigidbody sleeping thresholds, access to constraint references. 
Also added assert, to make sure users don't delete rigidbodies while constraints point to them.

685138d033 include paths should not be relative starting with "../ 
It leads to problems with certain compilers, when Bullet/src is located in a long pathname.
Keep include path starting with "LinearMath/, "BulletCollision/, or "BulletDynamics/

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