fixed some more warnings
added alignment macros to some classes
btPersistentManifold from 128 to 16 bytes aligned
prepare command to select collision filter mode (SIM_PARAM_UPDATE_COLLISION_FILTER_MODE)
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
allow 'useMaximalCoordinates' and 'useFixedBase' in pybullet.loadURDF.
enable split impulse for btRigidBody, even in btMultiBodyDynamicsWorld.
allow initialization of velocity and apply force for btRigidBody in pybullet/shared memory API.
process contact parameters in URDF also for btRigidBody (friction, restitution etc)
add pybullet.setPhysicsEngineParameter with numSolverIterations, useSplitImpulse etc.
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'
always pass in width, hight and viewMatrix, projectionMatrix, optionally lightDir
added helper methods computeViewMatrix, computeViewMatrixFromYawPitchRoll, computeProjectionMatrix, computeProjectionMatrixFOV
see Bullet/examples/pybullet/testrender.py + testrender_np.py for example use
add missing base_link.stl for husky.urdf
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)
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)
increase from 64 to 128 joints in shared memory API/pybullet
fix potential issue in tinyrenderer, related to missing segmentation mask buffer
report error if CMD_REQUEST_ACTUAL_STATE command on a multibody that exceed the number of links,
todo: stream data to allow arbitrary large number of links in shared memory API
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.
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
