add UDP network connection for physics client <-> server.
also set spinning friction in rolling friction demo (otherwise objects may keep on spinning forever)
- fixing various race conditions throughout (usage of static vars, etc)
- addition of a few lightweight mutexes (which are compiled out by default)
- slight code rearrangement in discreteDynamicsWorld to facilitate multithreading
- PoolAllocator::allocate() can now be called when pool is full without
crashing (null pointer returned)
- PoolAllocator allocate and freeMemory, are OPTIONALLY threadsafe
(default is un-threadsafe)
- CollisionDispatcher no longer checks if the pool allocator is full
before calling allocate(), instead it just calls allocate() and
checks if the return is null -- this avoids a race condition
- SequentialImpulseConstraintSolver OPTIONALLY uses different logic in
getOrInitSolverBody() to avoid a race condition with kinematic bodies
- addition of 2 classes which together allow simulation islands to be run
in parallel:
- btSimulationIslandManagerMt
- btDiscreteDynamicsWorldMt
- MultiThreadedDemo example in the example browser demonstrating use of
OpenMP, Microsoft PPL, and Intel TBB
- use multithreading for other demos
- benchmark demo: add parallel raycasting
-------------------------------------
This commit implements speeding up and slowing down examples. The
example can be influenced by the parameters. A separate example will be
added to show off the capabilities of the TimeWarpBase for other
examples.
The walkers work quite well, a successful evolution was run over night
and reached a walker distance of 7.2m.
URDF/SDF: add a flag to force concave mesh collisiofor static objects. <collision concave="yes" name="pod_collision">
VR: support teleporting using buttong, allow multiple controllers to be used, fast wireframe rendering,
Turn off warnings about deprecated C routine in btScalar.h/b3Scalar.h
Add a dummy return to stop a warning
Expose defaultContactERP in shared memory api/pybullet.
First start to expose IK in shared memory api/pybullet (not working yet)
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.
See bullet3/examples/Importers/ImportURDFDemo/DefaultVisualShapeConverter.h
Give the kuka_iiwa/model.urdf some blue color, not just orange, to mimick the original a bit better
Preparation for the CMD_CAMERA_IMAGE_COMPLETED command, to expose a virtual camera to the robotics API
Summary of changes:
1) Changed include paths to be relative to the current sources (affected
files: LoadMeshFromObj.cpp, Wavefront2GLInstanceGraphicsShape.h/cpp)
2) Added new tutorials in the ExtendedTutorials folder
3) Modified the main_opengl_single_example.cpp file to enable picking
support in standalone demos
example usage:
int main(int argc, char* argv[])
{
btInProcessExampleBrowserInternalData* data = btCreateInProcessExampleBrowser(argc,argv);
while (!(btIsExampleBrowserTerminated(data)))
{
}
btShutDownExampleBrowser(data);
return 0;
}
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.
