erwin.coumans 1526691f89 fixed memory leaks in ForkLiftDemo/VehicleDemo 
Thanks to mi076 for report+fix: http://bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2652
Minor syntax error fix in a Jamfile
 2009-05-14 17:03:42 +00:00
erwin.coumans e260bcd1b2 Added initial Smoothed Particle Hydrodynamics implementation (SPH), for CPU and CUDA. 
This software is contributed under the ZLib license by Rama Hoetzlein, http://www.rchoetzlein.com
We plan to integrate the SPH into the core Bullet library, including interaction with rigid bodies and soft bodies.

erwin.coumans 0cd0529c4a the component of the up axis needs to be scaled, to reduce roll. 2009-03-09 03:53:16 +00:00
erwin.coumans 700db838b1 Add 1D and 2D support for Bullet: using rigidbody->angularFactor(const btVector3& factor) and body->setLinearFactor(const btVector3& linearFactor); 
For example, to only allow linear motion in the X-Z plane, and only rotation around Y axis use:
	body->setLinearFactor(btVector3(1,0,1));
	body->setAngularFactor(btVector3(0,1,0));
Fix build issues with CodeBlocks, when generating projectfiles using CMake 2.6:
${OPENGL_glU_LIBRARY} should be ${OPENGL_glu_LIBRARY}
Fix build issue with CodeBlocks, comment out xmlfree in Extras/COLLADA_DOM/src/modules/LIBXMLPlugin/daeLIBXMLPlugin.cpp (will leak memory)

 2009-03-03 18:43:01 +00:00
erwin.coumans 90f96aec27 Introduced btActionInterface. This makes it easier to extend user-defined actions, such as vehicles and characters. 
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.
Some cosmetic cleanup: changed sourceforce/sf.net url to bulletphysics.com.
 2009-03-03 16:18:23 +00:00
erwin.coumans 459c22e7cb Synchronized changes of Bullet, from Blender. 
Added optional flag btSoftBody::appendAnchor(	int node,btRigidBody* body, bool disableCollisionBetweenLinkedBodies=false), to disable collision between soft body and rigid body, when pinned
Added btCollisionObject::setAnisotropicFriction, to scale friction in x,y,z direction.
Added btCollisionObject::setContactProcessingThreshold(float threshold), to avoid collision resolution of contact above a certain distance.
Avoid collisions between static objects (causes the CharacterDemo to assert, when a dynamic object hits character)
 2009-03-03 06:47:52 +00:00
erwin.coumans 5be9f8f301 basic implementation of self-collision for btSoftBody with collision clusters: perform regular soft body versus soft body, but disable collision detection between clusters that are connected/share any node (vertex). 
currently self-collision is always enabled for soft bodies that use clusters collision detectoin. to disable, call 'softbody.m_clusterConnectivity.clear' after 'generateClusters(...) call.
 2009-03-02 05:13:26 +00:00
erwin.coumans 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.

erwin.coumans 2a10a61f50 Some work-in-progress on making btDbvtBroadphase deterministic. When using the btSortedOverlappingPairCache, it seems deterministic now. todo: when using btHashedOverlappingPairCache. 2009-02-10 03:50:58 +00:00
erwin.coumans 98436a85c3 Fix issues with btSortedOverlappingPairCache, both for btAxisSweep3 and btDbvtBroadphase. 2009-02-09 22:57:52 +00:00
erwin.coumans cf751f5493 Add a convenience method to control the number of single-shot contact points for convex-convex collision detection, using the perturbation method.

erwin.coumans bcbe730471 Perform several rotation pertubations, to create multiple collision contact. works for convex versus plane. todo: convex versus convex. 
See issue http://code.google.com/p/bullet/issues/detail?id=20:

Note that the default number of pertubation iterations (10) and pertubation angle (0.05) can be modified through the collisionConfiguration:

	btConvexPlaneCollisionAlgorithm::CreateFunc* func = (btConvexPlaneCollisionAlgorithm::CreateFunc*)collisionConfiguration->getCollisionAlgorithmCreateFunc(BOX_SHAPE_PROXYTYPE,STATIC_PLANE_PROXYTYPE);
	func->m_numPertubationIterations = 0;
	func = (btConvexPlaneCollisionAlgorithm::CreateFunc*)collisionConfiguration->getCollisionAlgorithmCreateFunc(STATIC_PLANE_PROXYTYPE,BOX_SHAPE_PROXYTYPE);
	func->m_numPertubationIterations = 0;

erwin.coumans 0e3b04d952 Add COLLADA physics support for GImpact (allowing dynamic moving rigid bodies using concave collision shapes) in ColladaDemo, and ColladaConverter (import and export) 
Note: ColladaConverter will export a btGImpactConvexDecompositionShape the same as a btCompoundShape, so importing an exported btGImpactConvexDecompositionShape (roundtrip) creates a btCompoundShape

erwin.coumans 6db1b932fd Make the btDbvtBroadphase deterministic/reproducable, by sorting the btBroadphasePair using unique ID, instead of proxy address. 
The btAxisSweep3 didn't suffer from this issue, because proxies were always allocated in-order, as part of an array.
 2008-12-08 20:16:29 +00:00
erwin.coumans 65cdd7146f Use placement new for copy constructor of arrays. Thanks to M. Reuvers for the patch. 
http://bulletphysics.com/Bullet/phpBB3/viewforum.php?f=9

Generally, however, it is best to avoid copying entire arrays, but use a 
reference.

typedef btAlignedObjectArray<btSomeClass> Array;

Array a;
Array b = a;//avoid this whenever possible

This is much better:
Array& b = a;//use a reference
const Array& b = a; //or const reference

Thanks to Ole for reporting

Fix a bug , causing some deep penetrations to be missed. Not likely to have impacted many users, as such deep penetrations should have prevented in the first place.
Thanks a lot to Andy O'Neil for reporting and reproduction case.

erwin.coumans 7341c6ee7e Minor fixes to keep trunk compiling, while doing the refactoring. 2008-12-01 06:55:27 +00:00
erwin.coumans e80feca36b Big work-in-progress refactoring of the constraint solver: 
1) Add fast branchless SIMD support for constraint solver (Windows only until we get other contributions).
See resolveSingleConstraintRowGenericSIMD in Bullet/src/BulletDynamics/ConstraintSolver/btSequentialImpulseConstraintSolver.cpp
resolveSingleConstraintRowGenericSIMD can be used for all constraints, including contact, point 2 point, hinge, generic etc.

2) During this refactoring, all constraints support the obsolete 'solveConstraintObsolete' while we add 'getInfo1' and 'getInfo2' support.
This interface is almost identical interface to Open Dynamics Engine, to make it easier to port Dantzig LCP solver.

3) Some minor refactoring to reduce huge constructor overhead in math classes.

erwin.coumans e26b11ea5a fixed IBM Cell sdk build + demo (need to review related patch), thanks Jochen for reporting the issues. 2008-11-26 19:34:20 +00:00
erwin.coumans 82047e601e updated Bullet sequential impulse constraint solver, so it matches 100% ODE PGS quickstep solver innerloop, mainly by renaming variables... 2008-11-26 00:27:35 +00:00
erwin.coumans 7dda192bfc duplicate class name causes crashes, thanks to Nado and mickey for the report

erwin.coumans bdea80f2ca added missing Jamfile 2008-11-20 08:10:05 +00:00
erwin.coumans bab2854e16 minor update in Bullet user manual (needs a lot of work) 2008-11-20 07:52:24 +00:00
erwin.coumans decf91a34d Made btCollisionWorld::convexSweepTest and btGhostObject::convexSweepTest consistent. Both have an optional last argument for allowedCcdPenetration. 
Bugfix due to recent change in friction in constraint solver.
 2008-11-19 19:55:14 +00:00
erwin.coumans 50344c4a23 Add support for broadphase acceleration of convex cast (re-use rayTest implementation with an added aabb min/max, zero for rays) 
Add Concave Convexcast demo back in AllBulletDemos, and tweaked it a bit.
Fix view frustum of ForkLiftDemo (caused picking to fail)
Removed innerloop profiling for ray and convex casts, it hurts performance.
Set default #aabb's in CDTestFramework to 8192
