340a8f4704 add sigaction handler to Example Browser, to always shutdown shared memory
make GUI_SERVER more reliable
next attempt to connect to SHARED_MEMORY in Gym envs, if available, before DIRECT/GUI
allow software rendering fallback, even if ER_BULLET_HARDWARE_OPENGL is chosen in getCameraImage

ee30479a28 add option to log joint torques (due to user applied torques and/or motor torques)
See quadruped.py for an example:
p.startStateLogging(p.STATE_LOGGING_GENERIC_ROBOT, "genericlogdata.bin", maxLogDof = 16, logFlags = p.STATE_LOG_JOINT_TORQUES)
Thanks to JulianYG, in pull request https://github.com/bulletphysics/bullet3/pull/1273

bcc60224f0 all methods (except connect, obviously) have the physicsClientId argument, even if they don't use it. This makes it easier to create a wrapper API to store the physics client. This allows easier multi-threaded versions with multiple Bullet DIRECT instances (or SHARED_MEMORY, TCP, UDP etc).
See for example https://github.com/bulletphysics/bullet3/blob/master/examples/pybullet/gym/pybullet_envs/bullet/bullet_client.py and https://github.com/bulletphysics/bullet3/blob/master/examples/pybullet/gym/pybullet_envs/bullet/minitaur.py

60b60ef9fd add pybullet.connect(pybullet.GUI_SERVER) option. This allows shared memory connections, acting as a physics server. You can connect using SHARED_MEMORY to this GUI_SERVER. 2017-08-14 17:02:20 -07:00

88897cc744 implement pybullet.changeTexture. For now, the width/height has to match the target texture unique id, otherwise crashes may happen (a check for width/height match will be added)

a7aed37632 work on pybullet/C-API createMultiBody (still preliminary, only sphere/box collision shapes, no links/hierarchies yet, soon)
pybullet/C-API, expose linear/angular damping
fix some warnings (param name needs to be same in .h and .cpp)
fix potential startup threading issue (args were deleted in main thread while still possibly use in child thread)

db008ab3c2 Improve debug text/line rendering, can be use to draw frames and text in local coordinate of an object / link.
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

pybullet.setPhysicsEngineParameter(enableFileCaching=0)
