97547eda0d preliminary work towards saveState/restoreState and saveRestoreState.py example (not implemented yet)
allow multiple options in connect, for example: p.connect(p.GUI, options="--width=640, --height=480")

a9b59b4511 Finally refactored the PhysicsServerCommandProcessor::processCommand switch statements into over 50 separate functions.
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)

8e496036c6 More work on the C/C++ plugin system for pybullet/C-API:
Add preTickPluginCallback/postTickPluginCallback
User pointer for b3PluginContext, to store objects (class/struct instances)
Pass ints and floats as optional argument for plugin executePluginCommand

aafaa7e33e Expose optional "globalScaling" factor to pybullet.loadURDF and pybullet.loadSDF. This will scale the visual, collision shapes and transform locations.
Fix two_cubes.sdf (was lacking collision shape for second cube)

83f910711a Prepare/allow for non-Bullet2-based physics command processor in pybullet/Bullet-C-API
!!! Make sure to add examples/SharedMemory/PhysicsServerExampleBullet2.cpp to your build system, if needed
Bump up pybullet to version 1.0.9

5436b8f048 print better error warning, in case the physics client/server version mismatch.
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

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

433d11d8cf Add a btIDEbugDraw::clearLines, helps multi-threaded rendering of lines (while updating those lines in a dynamics world in a different thread)
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.

2a2c18e959 add more tinyaudio preparation, some test wav files, play sound on collision events. Will expose this in the C-API to pick wav files and collision threshold levels etc. Use the premake --audio flag to try it out. The TinyAudio example in the ExampleBrowser works on Mac, Linux and Windows, you can play notes by pressing keys. 2017-04-29 10:32:30 -07:00

4911916937 Expose 'flags' option for loadURDF, to allow customization of the URDF loading process while maintaining backward compatibility.
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.

cfd35840f0 initial implementation of state logging.
see examples/pybullet/logMinitaur.py for example. Other state logging will include general robot states and VR controllers state.

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)

9708392322 work-in-progress
add UDP network connection for physics client <-> server.
also set spinning friction in rolling friction demo (otherwise objects may keep on spinning forever)

c2ca88bf44 added b3PhysicsParamSetInternalSimFlags command, and pybullet setInternalSimFlags API.
//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)

a9b1544a9f Add premake support to build pybullet, Windows and Linux tested, will enable Mac in next commit.
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.

c28cd03fbd OpenVR controller can pick/drag objects. Instructions, Windows only:
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.
