Torsional and rolling friction for btMultiBody
 2016-09-01 14:57:46 -07:00
erwincoumans
85fd7f560c add first draft of contact point query in shared memory API 
b3SharedMemoryCommandHandle b3InitRequestContactPointInformation(b3PhysicsClientHandle physClient);
void b3SetContactFilterBodyA(b3SharedMemoryCommandHandle commandHandle, int bodyUniqueIdA);
void b3SetContactFilterBodyB(b3SharedMemoryCommandHandle commandHandle, int bodyUniqueIdB);
void b3GetContactPointInformation(b3PhysicsClientHandle physClient, struct b3ContactInformation* contactPointData);
Implemented for PhysicsClientSharedMemory, not for PhysicsDirect yet.
Add btCollisionObject::setUserIndex2

4094b9f0df Disable 'm_robotSim.setNumSimulationSubSteps' because it is not needed at the moment 
Fix issue in contact/friction between btMultibody and btRigidBody (external force/torque of btRigidBody was not taken into account during contact/friction setup)
Allow 0.1 mm slop in contact, to avoid loosing contact. Todo: allow contacts with positive distance in multibody solver.

c5164e503f fix in structure alignment of btMultiBodyLinkDoubleData and btMultiBodyDoubleData 
causing serialization issue in  URDF/SDF loading in double-precision mode on Windows 32bit.
(it was fine on Mac/Linux 64bit)
bump serialization version to 2.85, as we change the file format
fix in name clash in makesdna.cpp -> intptr_t is already defined.

ba8964c4ac [InverseDynamics] Support for Jacobians & derivatives 
This change adds support for calculating Jacobians and
dot(Jacobian)*u terms, along with the required support for
the 3xN matrices in the standalone math library.
It also adds functions to compute kinematics only (position, velocity, accel).
To facilitate tests, the Cl also adds a RandomTreeCreator to create
randomized multibody trees.
Thanks to Thomas Buschmann for this contribution!

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.
