Erwin Coumans c6a350b807 BulletInverseDynaimcs: re-applied fix 
PyBullet: increase humanoid training from 30 to 300M (need to figure out the right hyperparameters...)

 2018-01-15 11:59:00 -08:00
Erwin Coumans 79051b7611 allow to use colors from MJCF file as option (default to random Google colors), use p.loadMJCF(filename, flags=p.URDF_MJCF_COLORS_FROM_FILE 
fix quadruped.py example.
add PyBullet.isConnected() API, more friendly than PyBullet.getConnectionInfo()["connected"]
 2018-01-11 21:04:08 -08:00
erwincoumans 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.
 2018-01-10 11:16:50 -08:00
erwincoumans c4b1b84687 Enable 'global absolute velocities' by default for btMultiBody. See 8.3.2B Proposed resolution Jakub Stepien PhD Thesis 
https://drive.google.com/file/d/0Bz3vEa19XOYGNWdZWGpMdUdqVmZ5ZVBOaEh4ZnpNaUxxZFNV/view?usp=sharing
Fixes crashes due to rendering of softbody wireframe in the wrong thread (needs to be in 'debug' rendering section)

Erwin Coumans e97b751781 further work on urdfEditor.py, fix some serialization issues 2018-01-08 12:25:56 -08:00
Erwin Coumans c59a3763e5 tweak ImportMJCFSetup.cpp example MJCF humanoid a bit, clamp target positions to be within joint limits to avoid solver problems (conflicting constraints) 
add humanoid_manual_control.py PyBullet example which is similar to ImportMJCFSetup.cpp
 2018-01-04 13:14:11 -08:00
Erwin Coumans 4c6df650d4 skip serialization of empty contact manifolds. 2017-12-31 11:28:22 -08:00
Erwin Coumans f104765c47 added some template to restore (syncMultiBody, syncContactManifolds) for single float and double precision, in 'pybullet.restoreState' 2017-12-31 11:19:29 -08:00
Erwin Coumans 20e00d11d8 further work on saveRestoreState.py 2017-12-30 21:57:42 -08:00
Erwin Coumans 4084c1cc71 also add serializeContactManifolds to btSoftMultiBodyDynamicsWorld.cpp and btDiscreteDynamicsWorld. 2017-12-30 14:20:20 -08:00
Erwin Coumans 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.
