Usage:
Also updated pypi to latest, see https://pypi.python.org/pypi?:action=display&name=pybullet&version=0.1.7
Here are a few options for Mac OSX + Anaconda:
1) In the root of the Bullet Physics SDK source tree, run
CFLAGS="-DB3_NO_PYTHON_FRAMEWORK" python setup.py install
2) cmake, add the flag -DBUILD_PYBULLET_MAC_USE_PYTHON_FRAMEWORK=OFF
3) Globally, just use pip or pip3:
CFLAGS="-DB3_NO_PYTHON_FRAMEWORK" pip install pybullet
Option (3) may have an out-of-date pybullet/bullet version.
Add several MSVC optimization flags to cmake.
Bump up VERSION because serialization format changed
Expose btScalar& jointMaxForce, btScalar& jointMaxVelocity to 'getJointInfo2' API, add backwards compatibility to examples\Importers\ImportURDFDemo\URDFImporterInterface::getJointInfo.
pybullet: expose 4 more fields to getJointInfo: jointLowerLimit/jointUpperLimit/jointMaxForce/jointMaxVelocity
fix performance issue in CMD_ACTUAL_STATE_UPDATE_COMPLETED
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
option is disabled by default. When using cmake, use
cmake -DBUILD_PYBULLET=ON -DBUILD_PYBULLET_NUMPY=ON
then both testrender.py and testrender_np.py will work
without numpy only testrender.py works.
The numpy.reshape is likely a no-op when using numpy array,
so we could remove testrender_np.py...
See https://github.com/bulletphysics/bullet3/pull/774
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.
Disable a few Visual Studio warnings:
C4244: conversion from 'type1' to 'type2', possible loss of data
C4267: conversion from 'size_t' to 'type', possible loss of data
Considering the GCC/Clang counterpart '-Wconversion'
(https://gcc.gnu.org/wiki/NewWconversion) is not covered by '-Wall', it
seems to make more sense to disable these two warnings in Visual Studio,
rather than fixing these warnings with hundreds of static_cast<> in the
source code.
Improve CMake Windows support to build PyBullet (BUILD_PYBULLET)
Implement b3LoadSdfCommandInit in shared memory API
Implement pybullet SDF loading binding, in loadSDF API
TODO for SDF support is provide way to query object/link/joint information.
Use this recent cmake version (http://cmakems.codeplex.com/) or future cmake that has the Windows Phone/Store App support
Use the following defines in CMake:
-DCMAKE_SYSTEM_NAME=WindowsPhone or -DCMAKE_SYSTEM_NAME=WindowsStore
-DCMAKE_SYSTEM_VERSION=8.0 or -DCMAKE_SYSTEM_VERSION=8.1
Thanks to Microsoft OSS group for the patch!
It is tested in Aero2 demo (13) of AppSoftBodyDemo. Note that the cloth in Areo2 is not expensive enough to see benefits. Increase segments to see benefits.
Thanks a lot for the contribution.
