8e496036c6 More work on the C/C++ plugin system for pybullet/C-API: 
Add preTickPluginCallback/postTickPluginCallback
User pointer for b3PluginContext, to store objects (class/struct instances)
Pass ints and floats as optional argument for plugin executePluginCommand

815a56c9bc Allow to load a urdf file in the testplugin.cpp, as first quick test, example pybullet script: 
import pybullet as p
p.connect(p.GUI)
pluginUid = p.loadPlugin("E:/develop/bullet3/bin/pybullet_testplugin_vs2010_x64_debug.dll")
commandUid = 0
argument = "plane.urdf"
p.executePluginCommand(pluginUid,commandUid,argument)
p.unloadPlugin(pluginUid)

eb97e06280 fix minitaur.urdf: move lower-leg inertia to center, add missing collision for one of the motors, add contact parameters for friction_anchor, spinning friction, compliance (stiffness/damping) 
fix in indexing for maximal coordinates (unused by default, still experimental, requires many iterations for Minitaur due to extreme mass-ratio, hence use of reduces/generalized coordinates)
modify quadruped.py to test maximal coordinates
wrap angular servo (positional) target within [-PI,PI] in btGeneric6DofSpring2Constraint
add 'j' key to show body frames in wireframe/debug mode
 2017-09-02 01:05:42 -07:00
erwincoumans
ee30479a28 add option to log joint torques (due to user applied torques and/or motor torques) 
See quadruped.py for an example:
p.startStateLogging(p.STATE_LOGGING_GENERIC_ROBOT, "genericlogdata.bin", maxLogDof = 16, logFlags = p.STATE_LOG_JOINT_TORQUES)
