75e86051c2 Add inverse kinematics example with implementations by Sam Buss. 
Uses Kuka IIWA model description and 4 methods:
Selectively Damped Least Squares,Damped Least Squares,
Jacobi Transpose, Jacobi Pseudo Inverse
Tweak some PD values in Inverse Dynamics example and Robot example.

c28cd03fbd OpenVR controller can pick/drag objects. Instructions, Windows only: 
Compile using premake+visual studio, and compile App_SharedMemoryPhysics_VR
Compile pybullet using cmake using cmake -DBUILD_PYBULLET=OFF -DCMAKE_BUILD_TYPE=Release ..
Create a symbolic link from c:\python\dlls\pybullet.pyd to C:\develop\bullet3\cmp\lib\Release\pybullet.dll
App_SharedMemoryPhysics_VR
Run Python. Here are some Python lines to get going:
import pybullet as p
p.connect(p.SHARED_MEMORY)
p.loadURDF("cube.urdf")
p.setGravity(0,0,-10)
p.setRealTimeSimulation(1)

Allow real-time simulation in physics server, add pybullet command setRealTimeSimulation to control it
Mesh decimation (reduce number of triangles/vertices) using a Blender modifier for Kuka IIWA and Husky
Disabled the 'glFlush' commands in GLInstancingRenderer.
Add VR controller methods to examples\CommonInterfaces\CommonExampleInterface.h
Use the ANSI version in Windows file/string operations instead of unicode, hope this doesn't break builds.

also fixed some memory issue in InverseDynamicsExample (the base class is supposed to delete collision shape memory)

6c9bfce975 Support btMultiBody soft contact using ERP and CFM. Also support custom relaxation parameter to allow successive over relaxation. 
Added demos for rigid and multi body soft (compliant) contact.
Will also add simplified Hertz compliant contact, by dynamically modifying the ERP/CFM to mimic a non-linear spring.
Note that btManifoldPoint is growing too big, we need to implement proper contact constraints derived from btTypedConstraint.
