- 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
add wsg50 gripper with modified r2d2 gripper tip
expose a fudge factor to scale inertia, to make grasping more stable
(until we have better grasping contact model/implementation)
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.
Fix uninitialized variable jointDamping/jointFriction in SDF importer
Add SDF <pose> parsing in visual, inertial, collision elements.
Slight improvement in TinyRender loading performance of largish meshes (30k vertices)
Reduce #define MAX_SDF_BODIES to 500, due to some issue in client code, todo: figure out what the issue is.
b3RobotSimAPI support SDF file loading
Tiny improvement in OpenGL hardware renderer lighting, to distinguish faces without textures
------------------------------------------------
The slider applies the selected displacement force according to the chosen scalar and falls back to zero when moved below an absolute value of 0.2.
add an example using 'direct'
fix the send-desired-state commands, to add flags for arguments set, using default values.
Start exposing SDF loading in shared memory api, not fully implemented yet.
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
