db3122233f remove that odd triangle in the origin of samurai castle (VR) 
add rolling/spinning friction to cube, remove it from plane/samurai.urdf
URDF2Bullet: support joint limits for revolute and prismatic, only if defined (if upper < lower, disable limit)
add some profiling markers to improve performance

1d88cf71e4 separate spinning friction (torsional friction around contact normal) from 
rolling friction (orthogonal to contact normal)

e5a8eb2425 rolling friction -> combine using rolling*normal friction, add for both objects. 
rolling friction -> only along the normal, until we have separate rolling friction coefficients on normal and non-normal directions
Don't teleport with grasping controller (VR)
Tune VR grasping a bit.

85fd7f560c add first draft of contact point query in shared memory API 
b3SharedMemoryCommandHandle b3InitRequestContactPointInformation(b3PhysicsClientHandle physClient);
void b3SetContactFilterBodyA(b3SharedMemoryCommandHandle commandHandle, int bodyUniqueIdA);
void b3SetContactFilterBodyB(b3SharedMemoryCommandHandle commandHandle, int bodyUniqueIdB);
void b3GetContactPointInformation(b3PhysicsClientHandle physClient, struct b3ContactInformation* contactPointData);
Implemented for PhysicsClientSharedMemory, not for PhysicsDirect yet.

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.

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)

99acea9594 btVoronoiSimplexSolver::inSimplex can return when first 'found=true' is set instead of going through all points, since found is never set to false in any other condition. 
PersistentManifold replaceContactPoint set the same values for m_appliedImpluse; remove redunant set.

workaround for wrong gjk/epa contact normal, add 'replay' command log feature: no mouse interaction during replay etc.

d6464ce40d add 'replay' command log feature: no mouse interaction during replay, and use a fixed number of sim steps in stepSimulation. 
workaround for reversed separating normal in gjk/epa when using very small shapes, detect case and revert normal.
use smaller world size (10 units versus 100) for higher resolution shadow map
use a hard-coded rolling friction of 0.2 for objects in physics server (will make this configurable)
fix loading of command log files, when platform features are different (64bit/32bit)
