ff43cea263 Fix some deactivation issues with btMultiBodyDynamicsWorld, should also improve performance for PyBullet with larger worlds
(even when sleeping is disabled, islands are split)

a69442d119 Some optimizations for btMultiBodyJointMotor (skip constraint generation if maxImpulse/maxForce = 0) and
skip constraint row generation if joint limit is not violated.

75e86051c2 Add inverse kinematics example with implementations by Sam Buss.
Uses Kuka IIWA model description and 4 methods:
Selectively Damped Least Squares,Damped Least Squares,
Jacobi Transpose, Jacobi Pseudo Inverse
Tweak some PD values in Inverse Dynamics example and Robot example.

6e9eb13235 implement joint reaction forces for mobilizer motor/limit, by passing the constraint forces as 'external forces' and going through the Articulated Body Algorithm
minor refactor for forwardKinematics, store the cached world transform in each btMultiBody::link

89edc40d61 First step in btMultiBody joint force/torque feedback. There is still some work to be done for 'mobilizer limit/motor'.
See examples/MultiBody/TestJointTorqueSetup and examples/Constraints/TestHingeTorque for joint feedback.

7151865c16 Introduce kF_UseGjkConvexCastRaytest, and make kF_UseSubSimplexConvexCastRaytest the default for btCollisionWorld::rayTest See https://github.com/bulletphysics/bullet3/issues/34
Add btCollisionObject::setIgnoreCollisionCheck to disable collisions between specific instances, without having a btTypedConstraint. See https://github.com/bulletphysics/bullet3/issues/165

Make btMultiBody and btMultiBodyJointMotor backwards compatible with Bullet 2.82 API (single-DOF API)

0024c87316 move the m_maxAppliedImpulse into base class, and use it for motor strength/point to point constraint strength 2013-10-22 21:49:52 +00:00

488dd44835 Added btMultiBodyPoint2Point, it can be used between btMultiBody vs btMultiBody or btMultiBody vs btRigidBody
Allow picking of btMultiBody, using a btMultiBodyPoint2Point constraint, with limited strength to avoid adding too much energy to the system (= blowup)
Add btMultiBodyJointMotor, it can be used in combination with joint limit (just add the joint limit after the motor, to avoid jitter)
