5e6cfd70b5 iOS platform and Android don't have __thread local storage, so avoid multi-threaded profiler on those (only on _WIN32, __linux__ and __APPLE__ and not TARGET_OS_IPHONE
Add a Sleep(0) for Windows to yield threads (and not Sleep(1))

fdd517e00f First step towards a MuJoCo MJCF importer for Bullet. It can load the humanoid.xml, ant.xml and some other OpenAI GYM asset files. Not all fields are converted, so it is work-in-progress. This is useful for Reinforcement Learning experiments, and would also help integration with DeepMind Lab. 2016-12-30 18:32:57 -08:00

82995a8343 pybullet, more robust multi-server connections
Windows shared memory: allow to use custom key.
Improve GUI performance on Windows, submit letters in text as a batch (fewer draw-calls)
quadruped.py: first try to connect to SHARED_MEMORY, if it fails (<0) use GUI
increase Chrome about://tracing json export capacity (press 'p' in Example Browser)
UDP physics server: add --port and --sharedMemoryKey command-line arguments
PhysicsServerExample: add --sharedMemoryKey command-line option (for VR example too)
ExampleBrowser: sleep a few milliseconds if rendering is too fast, use --minUpdateTimeMicroSecs=0 to disable

9ee1c4ec24 regular OR wireframe rendering, not both
add option to perform filtering of 'getClosestPoints' using linkA/linkB.
don't use 'realtimesimulation' as default
add/remove debug items within same thread
pybullet, report contact points and normal as [x,y,z] triplet/vector, not 3 scalars
separate 'getClosestPointsAlgorithm': box-box doesn't report closest points with positive distance, and the query shouldn't impact regular 'closesst points'

1c3686ca51 MultiThreaded Demo:
- 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

f0f694145d Implement TimeWarpBase.
-------------------------------------
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.
