71d4a90c98 btMultiBody: fix indexing issue causing wrong friction to be reported (has no effect, since we don't use warmstarting for multibody) 2018-10-06 15:25:22 -07:00

ab8f16961e Code-style consistency improvement: 
Apply clang-format-all.sh using the _clang-format file through all the cpp/.h files.
make sure not to apply it to certain serialization structures, since some parser expects the * as part of the name, instead of type.
This commit contains no other changes aside from adding and applying clang-format-all.sh

Erwin Coumans
b5495e789d Change constraint solver threshold-based termination condition on residual of velocity threshold, not on residual of impulse threshold. 
This avoids issues with systems with large mass ratios.

Test: add this to BasicDemo/BasicExample.cpp in initPhysics

	m_dynamicsWorld->getSolverInfo().m_numIterations = 1000;
	m_dynamicsWorld->getSolverInfo().m_leastSquaresResidualThreshold = 1e-4;

22b4809891 leave m_useGlobalVelocities to false, until enabled, for backward compatibility 
use URDF_GLOBAL_VELOCITIES_MB flag in PyBullet loadURDF.
fix robot_bases.py due to new fields in getJointInfo.
backward compabitibility: BulletMJCFImporter, keep creating btMultiSphereShape for MJCF capsules with fromto, instead of shifted btCapsuleShapeZ, unless if CUF_USE_IMPLICIT_CYLINDER is used.

0326fa93a8 made some progress in saving and restoring the state during the simulation, with identical results. 
Option to de/serialize btPersistentContactManifolds and fix lossy conversion during btMultiBody de/serialization of base world transform
(serialize the quaternion, not the converted 3x3 matrix)
There are still several caches not taken into account, and btMultiBody links/constraints are not deserialized yet etc.
See examples\pybullet\examples\saveRestoreState.py for an example.
