5158c1ae98 add python dumpLog.py utility to view log files created using 'startStateLogging'
don't enable <CTRL> for hotkeys yet
add some more profile markers
log objectId and linkIndex as signed int ('i') and not unsigned int 'I'
fix issue in startStateLogging: number of parameters was wrong

suppress lack of 'plane' visual support in urdf/sdf import
getBodyName default to "" to avoid breaking cloudsim
expose bodyName when requesting body info (sdf/mjcf import)

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

80a0b51a1d MJCF: fix cylinders in MJCF, also (possibly) fixes capsules in tiny renderer 2017-03-22 00:36:28 +03:00
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)

63486a712c VR video recording, use command-line --mp4=videoname.mp4
tune gripper grasp example with tefal pan, 800Newton force.
URDF importer: if using single transform 1 child shape, don't use compound shape.
if renderGUI is false, don't intercept mouse clicks
add manyspheres.py example (performance is pretty bad, will look into it)

fdd517e00f First step towards a MuJoCo MJCF importer for Bullet. It can load the humanoid.xml, ant.xml and some other OpenAI GYM asset files. Not all fields are converted, so it is work-in-progress. This is useful for Reinforcement Learning experiments, and would also help integration with DeepMind Lab. 2016-12-30 18:32:57 -08:00

82995a8343 pybullet, more robust multi-server connections
Windows shared memory: allow to use custom key.
Improve GUI performance on Windows, submit letters in text as a batch (fewer draw-calls)
quadruped.py: first try to connect to SHARED_MEMORY, if it fails (<0) use GUI
increase Chrome about://tracing json export capacity (press 'p' in Example Browser)
UDP physics server: add --port and --sharedMemoryKey command-line arguments
PhysicsServerExample: add --sharedMemoryKey command-line option (for VR example too)
ExampleBrowser: sleep a few milliseconds if rendering is too fast, use --minUpdateTimeMicroSecs=0 to disable
