ae07ce2ea7 * add BT_USE_INVERSE_DYNAMICS_WITH_BULLET2 2017-03-29 17:11:26 +03:00
Erwin Coumans
7503418c72 Split Bullet/src/LinearMath/btSerializer.cpp into btSerializer64.cpp to make it easier to rebuild serialization structure. 
Add several MSVC optimization flags to cmake.
Bump up VERSION because serialization format changed
Expose btScalar& jointMaxForce, btScalar& jointMaxVelocity to 'getJointInfo2' API, add backwards compatibility to examples\Importers\ImportURDFDemo\URDFImporterInterface::getJointInfo.

pybullet: expose 4 more fields to getJointInfo: jointLowerLimit/jointUpperLimit/jointMaxForce/jointMaxVelocity

61b28621ea minor fix in friction anchors for btMultiBody 2017-03-21 09:24:00 -07:00
Erwin Coumans
0c874aa43a fix issue introduced in previous commit, related to 
btMultiBodyConstraintSolver friction/penetration handling
 2017-03-20 19:38:59 -07:00
Erwin Coumans
0b017b0f53 fix issue with btMultiBody friction in combination with soft contacts (friction should not re-use normal contact cfm/erp) 
implement friction anchors, position friction correction, disabled by default. Use colObj->setCollisionFlag(flag | CF_HAS_FRICTION_ANCHOR); See test/RobotClientAPI/SlopeFrictionMain.cpp. In URDF or SDF, add <friction_anchor/> in <contact> section of <link> to enable.
PhysicsServer: properly restore old activation state after releasing picked object
btMultiBodyConstraintSolver: disable flip/flop of contact/friction constraint solving by default (it breaks some internal flaky unit tests)

4ee09c264c Avoid using unitialized values. 
m_gravity was used before it was initialized. Simplest way to avoid
it is to call any method first after all values are initialized.

1c3686ca51 MultiThreaded Demo: 
- fixing various race conditions throughout (usage of static vars, etc)
 - addition of a few lightweight mutexes (which are compiled out by default)
 - slight code rearrangement in discreteDynamicsWorld to facilitate multithreading
 - PoolAllocator::allocate() can now be called when pool is full without
     crashing (null pointer returned)
 - PoolAllocator allocate and freeMemory, are OPTIONALLY threadsafe
     (default is un-threadsafe)
 - CollisionDispatcher no longer checks if the pool allocator is full
     before calling allocate(), instead it just calls allocate() and
     checks if the return is null -- this avoids a race condition
 - SequentialImpulseConstraintSolver OPTIONALLY uses different logic in
     getOrInitSolverBody() to avoid a race condition with kinematic bodies
 - addition of 2 classes which together allow simulation islands to be run
   in parallel:
    - btSimulationIslandManagerMt
    - btDiscreteDynamicsWorldMt
 - MultiThreadedDemo example in the example browser demonstrating use of
   OpenMP, Microsoft PPL, and Intel TBB
 - use multithreading for other demos
 - benchmark demo: add parallel raycasting

ba8964c4ac [InverseDynamics] Support for Jacobians & derivatives 
This change adds support for calculating Jacobians and
dot(Jacobian)*u terms, along with the required support for
the 3xN matrices in the standalone math library.
It also adds functions to compute kinematics only (position, velocity, accel).
To facilitate tests, the Cl also adds a RandomTreeCreator to create
randomized multibody trees.

6c9bfce975 Support btMultiBody soft contact using ERP and CFM. Also support custom relaxation parameter to allow successive over relaxation. 
Added demos for rigid and multi body soft (compliant) contact.
Will also add simplified Hertz compliant contact, by dynamically modifying the ERP/CFM to mimic a non-linear spring.
Note that btManifoldPoint is growing too big, we need to implement proper contact constraints derived from btTypedConstraint.
 2016-02-22 18:40:00 -08:00

645a88176d Enable softness for btRigidBody contacts. This is implemented by some value (CFM, constraint force mixing) to the main diagonal of A. 
CFM for contacts use world CFM value by default, and can override with custom CFM value using the
BT_CONTACT_FLAG_HAS_CONTACT_CFM stored in m_contactPointFlags.
Boolean m_lateralFrictionInitialized is replaced 'BT_CONTACT_FLAG_LATERAL_FRICTION_INITIALIZED' flag stored in int m_contactPointFlags in btManifoldPoint.
Enable successive over-relaxation parameter (SOR) for contacts. btMLCPSolver uses global CFM.
In one of the next commits, contact softness will be enabled btMultiBody contacts.
Also need to review use of CFM in btMLCPSolvers (only world CFM is used at the moment)

5d40d90bd0 add btMultiBodyConstraint::finalizeMultiDof API: if you add multi-body constraints to a multi-dof btMultiBody, before it has been finalized using the btMultiBody::finalizeMultiDof call, 
then you have to manually call the btMultiBodyConstraint::finalizeMultiDof for all multi-dof multi body constraints.

92dabdc07d Fix a couple of bugs in 2dConvex Hull algorithm. 
* Need to use atan2 so 3d angles are calculated properly after projection.
* Need to handle case where the first tripple of points is non-convex,
previously this would cause the algorithm to fail with only 1 point.

b1863f7ce2 Refactored GJK, EPA and MPR as a template class, reducing/removing the dependencies 
to the rest of the Bullet code base. This code will replace the original GJK/EPA
in a future commit.

Added btMprPenetration, an implementation of Minkowski Portal Refinement
by Daniel Fiser. Original MPR idea is by Gary Snethen, and the first
implementation is here: https://github.com/erwincoumans/xenocollide
It is an alternative to EPA, although computing the local penetration depth.
EPA computes the global penetration depth. In many cases, MPR is sufficient
and performs better than EPA.

b7699024e2 Fix for use of uninitialized variables. 
m_implicitShapeDimensions was used in setMargin, called from setSafeMargin
from constructors of btBoxShape, btCylinerShape and btBox2dShape,
effectively using uninitialized variable and leading to floating point
exceptions.
It was working correctly only because in the same constructor
m_implicitShapeDimensions was reinitialized after setSafeMargin.
Properly initialize variable before use by first setting it up and only
then using it in setSafeMargin.
