2fb686b937 change btMultiBody to allow removal/changing of links 
(still not easy to modify the link structure of a btMultiBody -> You have to manually re-link parents, copying links around etc)

542c53fb30 Don't pass along unused btStackAlloc everywhere. The API change might user code (derived classes with the old virtual method are not called anymore) 2013-05-08 22:45:35 +00:00

73b217fb07 Apple contribution for OSX SSE and iOS NEON optimizations unit tests, thanks to Jordan Hubbard, Ian Ollmann and Hristo Hristov. 
For OSX:
cd build
./premake_osx xcode4
for iOS:
cd build
./ios_build.sh
./ios_run.sh

Also integrated the branches/StackAllocation to make it easier to multi-thread collision detection in the near future. It avoids changing the btCollisionObject while performing collision detection.

As this is a large patch, some stuff might be temporarily broken, I'll keep an eye out on issues.

729a883b71 attempt to let Maya plugin build under Linux using cmake 
Thanks redpawfx for the feedback, see http://code.google.com/p/bullet/issues/detail?id=221

7a175fb65e Add pairwise collision test: 
void	btCollisionWorld::contactPairTest(btCollisionObject* colObjA, btCollisionObject* colObjB, ContactResultCallback& resultCallback)

5907f81774 Add void btCollisionWorld::contactTest(btCollisionObject* colObj, ContactResultCallback& resultCallback); 
The user should derive its own class from ContactResultCallback and implement the following callback (similar to the gContactAddedCallback):

virtual	btScalar	addSingleResult(btManifoldPoint& cp,	const btCollisionObject* colObj0,int partId0,int index0,const btCollisionObject* colObj1,int partId1,int index1) = 0;

c26f5e4b6e apply patch to allow soft body rayTest. Minor change in patch: test for current hitfraction, so only report hits closer than current closest hit fraction.

fcd2b93a22 fix in box-box contact generation: choose better contact point location (along contact normal) when objects are swapped. 
move debugDrawWorld to btCollisionWorld.
improved CollisionInterfaceDemo, show how to perform a closest point query for objects that are not in the collision world.
removed a bit of garbage from the debug drawer

49a0b479c6 Switch off an optimization by default, to avoid support burden: update all objects AABBs and not just the active objects. 
Call world->setForceUpdateAllAabbs( false) to re-enable the optimization: it will only update active objects (skipping static geometry)

dc4180f1ce + fix bug in SoftDemo: use removeRigidBody for rigid bodies, instead of removeCollisionObject 
+ use default convex drawing instead of special cylinder drawing (caps are wrongly drawn)
+ allow camera translation using middle-mouse button in SoftDemo
+ add/removeCollisionObject virtual

210fe36106 Add backface culling and option to keep unflipped hit normal in case a ray hits a back-facing triangle. 
Usage: set RayResultCallback.m_flags to kF_FilterBackfaces, optionally combined with kF_KeepUnflippedNormal.
Thanks Andy O'Neil for the patch!

Remove the force_inline for some internal constraint solver methods, it makes re-use easier.

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)

4cbb3f2e7b Added btGhostObject and btPairCachingGhostObject functionality. 
It is a fast way to keep track of overlapping objects in an area, and doing rayTest and convexSweepTest for overlapping objects, instead of btCollisionWorld::rayTest/convexSweepTest.

Updated KinematicCharacterController to use btPairCachingGhostObject.

6f80b98a67 - fix issue with convex cast: results further away (larger hitfraction) could overwrite closer results 
- minor naming convention thing (variables start with lower case)
- renamed MotorDemo

ec76f2e0a3 - keep track of all memory allocations (gNumAllignedAllocs/gNumAllignedFree)

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

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);

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.

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/

c791a3192c In the copy constructor initializer list of LocalRayResult in 
btCollisionWorld.h  line 139 (version 2.48) it reads:
m_localShapeInfo(m_localShapeInfo),
which should be:
m_localShapeInfo(localShapeInfo),

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
