pybullet.changeVisualShape(obUid,linkIndex,specularColor=[R,G,B]) and Bullet C-API b3UpdateVisualShapeSpecularColor
Bug fixes in b3ResourcePath::findResourcePath resolution.
add stadium.sdf and roboschool/models_outdoor/stadium assets https://github.com/openai/roboschool/tree/master/roboschool/models_outdoor/stadium
minor fixes to obj2sdf
example:
kuka = p.loadURDF("kuka_iiwa/model.urdf")
p.getNumJoints(kuka)
pybullet.addUserDebugLine([0,0,0],[0,0,0.1],[0,0,1],trackObjectUniqueId=2,trackLinkIndex=6)
pybullet.addUserDebugText("tip", [0,0,0.1],textColorRGB=[1,0,0],trackObjectUniqueId=2,trackLinkIndex=6)
Also allow to render text using a given orientation (instead of pointing to the camera), example:
pybullet.addUserDebugText("tip", [0,0,0.1],textColorRGB=[1,0,0],textOrientation=[0,0,0,1], trackObjectUniqueId=2,trackLinkIndex=6)
Add drawTexturedTriangleMesh, for drawing 3d text.
Expose readSingleInstanceTransformToCPU, to extract position/orientation from graphics index.
updateTexture: allow to not flip texels around up axis
for GLInstancingRenderer (OpenGL3+) and SimpleOpenGL2Renderer (OpenGL2)
Refactored the add/remove object pool in Bullet3Common/b3ResizablePool.h
Added CommonRigidBodyBase::deleteRigidBody, also removing its graphics instance.
tune gripper grasp example with tefal pan, 800Newton force.
URDF importer: if using single transform 1 child shape, don't use compound shape.
if renderGUI is false, don't intercept mouse clicks
add manyspheres.py example (performance is pretty bad, will look into it)
[pybullet] expose contactBreakingThreshold
- 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)
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.
add test for VR HUD/sub-titles
fix issue in previous commit, partial string use %.8s not %8.s
use long long int in b3Clock
fix warning/error in pointer alignment in serialization
Fix pybullet Windows compilation.
