1b03871b4d use explicit size for name, to avoid issue converting/marshalling data to C#
example to call b3VisualShapeInformation from C# and marshall b3VisualShapeData (after loadURDF)
See examples\pybullet\unity3d\examples\NewBehaviourScript.cs

acbe457d31 add option to statically link a plugin, select the postFix (to avoid naming conflict of multiple plugins functions ('initPlugin' becomes initPlugin_postFix)
pass events (keyboard, mouse, vr controllers etc) to the plugin, and clear them after the tick callback, so that it doesn't interfere with Python 'getEvents'

b1f8eb74a4 bump up shared memory version number
add option to recompute forward kinematics, to be consistent with link velocities in pybullet.getLinkState (..., computeForwardKinematics=0/1), thanks to Jeff Bingham for bringing up this inconsistency

270a036cd7 add experimental vrSyncPlugin, that syncs the position/orientation of a vr controller to a gripper (through a constraint)
This is in C++ and the sync runs at the simulation speed (240 Hz), so there is less lag than in Python.
Modify the pybullet/examples/vr_kuka_setup.py at the end to do this:

plugin = p.loadPlugin("e:/develop/bullet3/bin/pybullet_vrSyncPlugin_vs2010_x64_release.dll")
controllerId = 3
p.executePluginCommand(plugin ,"bla", [controllerId,pr2_cid],[50])

ee30ca93c5 [sharedmemory] Fill-out calculateJacobian command.
The server command processor actually didn't do anything with
the local point that was passed along with the calculateJacobian
command. Added in the necessary bit of math to return the
corresponding jacobian.

Also, fixed a typo in pybullet that was returning the same
jacobian for translation and rotation.

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
