add optional flags in pybullet.resetSimulation.
fix compile issue due to SKIP_DEFORMABLE_WORLD
fix issue in .obj importer (todo: replace with tiny_obj_loader)
todo: replace std::ifstream fs; by fileIO usage.
expose minGraphicsUpdateTimeMs through PyBullet.connect(p.GUI, options="minGraphicsUpdateTimeMs=32000"), by default OpenGL rendering runs at 4000microseconds intervals.
allow a maximum of 128k objects
fix meshScale for PyBullet.createCollisionShape for custom mesh
expose Pybullet.setPhysicsEngineParameter(minimumSolverIslandSize=...), larger minimum batches group solver constraints together in the same island, to reduce calling overhead (even if they are not related)
Apply clang-format-all.sh using the _clang-format file through all the cpp/.h files.
make sure not to apply it to certain serialization structures, since some parser expects the * as part of the name, instead of type.
This commit contains no other changes aside from adding and applying clang-format-all.sh
Implement collisionFilterPlugin, use setCollisionFilterPair to enable or disable collision detection between specific pairs of objects.
Also, expose setCollisionFilterGroupMask as PyBullet API and in urdf using the tag <collision group="1" mask="2"/>.
See examples/pybullet/examples/collisionFilter.py for an example.
PyBullet default: Lower the warmstarting factor, for maximal coordinates rigid bodies for more stable simulation.
Add btCollisionWorld::refreshBroadphaseProxy to easier recreate the broadphase proxy without adding/removing objects to the world.
add grpcPlugin, it can work in GUI, SHARED_MEMORY_SERVER, DIRECT and other modes.
example script to start server from pybullet:
import pybullet as p
p.connect(p.GUI)
#if statically linked plugin
id = p.loadPlugin("grpcPlugin")
#dynamics loading the plugin
#id = p.loadPlugin("E:/develop/bullet3/bin/pybullet_grpcPlugin_vs2010_x64_debug.dll", postFix="_grpcPlugin")
#start the GRPC server at hostname, port
if (id>=0):
p.executePluginCommand(id, "localhost:1234")
Only in DIRECT mode, since there is no 'ping' you need to call to handle RCPs:
numRPC = 10
while (1):
p.executePluginCommand(id, intArgs=[numRPC])
- Limits the maximum number of threads to 64, since btThreadSupportPosix
and btThreadsupportWin32 don't support more than 64 bits at this moment,
due to the use of UINT64 bitmasks. This could be fixed by using
std::bitset or some other alternative.
- Introduces a threadpool class, b3ThreadPool, which is a simple wrapper
around btThreadSupportInterface and uses this instead of the global task
scheduler for parallel raycasting. This is actually quite a bit faster
than the task scheduler (~10-15% in my tests for parallel raycasts),
since the advanced features (parallelFor) are not necessary for the
parallel raycasts.
- Puts 16*1024 of MAX_RAY_INTERSECTION_MAX_SIZE_STREAMING in
parentheses, since it otherwise causes problems with other operators
of equal precedence and introduces a smaller constant for Apple targets.
- Refactors the parallel raycasts code and adds some more profiling.
Use btCylinderShapeZ for URDF cylinder, instead of converting it to a btConvexHullShape.
Implement PyBullet.getCollisionShapeData
Extend PyBullet.getDynamicsInfo / b3GetDynamicsInfo, remove flag (don't rely on API returning a fixed number of elements in a list!)
Extend PyBullet.getJointInfo: add parentIndex
Over time, some of those functions can be moved into separate plugins, similar to vrSyncPlugin (either statically/dynamically linked plugins or dynamically loaded at run-time)
Add preTickPluginCallback/postTickPluginCallback
User pointer for b3PluginContext, to store objects (class/struct instances)
Pass ints and floats as optional argument for plugin executePluginCommand
fix in b3HashString
remove many unused dependencies from kuka_grasp_block_playback.py (time,math, datetime ,numpy,pylab ,sys, os, fnmatch,argparse were not used!)
move block_grasp_log.bin from Bullet3/data to Bullet3/examples/pybullet/examples/data folder.
PhysicsServerCommandProcessor, derive from CommandProcessorInterface to prepare for different back-end implementation
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
Expose COV_ENABLE_VR_RENDER_CONTROLLERS, to enable/disable rendering of controllers (and some frames) in VR
Expose COV_ENABLE_RENDERING to enable/disable rendering.
Fix some multi-threading issues (potential crashes), related to debug drawing/rendering in one thread, while changing the dynamics world/removing/resetSimulation in a different thread.
For example: URDF_USE_INERTIA_FROM_FILE flag. By default, URDF2Bullet will re-compute the inertia tensor based on mass and volume, because most URDF files have bogus Inertia values.
add missing 1.sdf for Bullet/data/kitchens/1.sdf
add support for getting keyboard events (pybullet.getKeyboardEvents and b3RobotSimulatorClientAPI::getKeyboardEvents)
vrevent.py: add a Tiltbrush-style drawing example using pybullet
Expose getVREvents to pybullet / shared memory API, access to any VR controller state & state changes.
Improve performance of user debug lines (pybullet/shared memory API) by batching lines with same color/width
expose rayTest to pybullet/shared memory API (single ray for now)
add pybullet getMatrixFromQuaterion
add UDP network connection for physics client <-> server.
also set spinning friction in rolling friction demo (otherwise objects may keep on spinning forever)
//Use at own risk: magic things may or my not happen when calling this API.
This allows to enable/disable robot assets (samurai world, gripper, KUKA robot etc) in Physics Server (and App_PhysicsServerVR etc)
1 = create robot assets
2 = create experimental box-vr-gui
Add optional command-line parameter for App_PhysicsServerVR, --norobotassets, to start with an empty world, no assets in VR (no gripper, no kuka)
Expose inverse dynamics to Bullet shared memory API, through b3CalculateInverseDynamicsCommandInit and
b3GetStatusInverseDynamicsJointForces command/status. See PhysicsClientExeample or pybullet for usage.
Add option for Windows and Linux to set python_lib_dir and python_include_dir for premake and --enable_pybullet option
Expose inverse dynamics to pybullet: [force] = p.calculateInverseDynamics(objectIndex,[q],[qdot],[acc])
Thanks to Jeff Bingham for the suggestion.
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.
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.
