a85a4f387b more work on UrdfEditor.py 2018-01-06 15:00:20 -08:00

c59a3763e5 tweak ImportMJCFSetup.cpp example MJCF humanoid a bit, clamp target positions to be within joint limits to avoid solver problems (conflicting constraints) 
add humanoid_manual_control.py PyBullet example which is similar to ImportMJCFSetup.cpp

79d78a325a Start of a urdfEditor.py, limited support to extract a URDF from a PyBullet body. 
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

9c55b61315 pybullet.createVisualShape: process sphere radius, box half extents, capsule+cylinder radius/length

0326fa93a8 made some progress in saving and restoring the state during the simulation, with identical results. 
Option to de/serialize btPersistentContactManifolds and fix lossy conversion during btMultiBody de/serialization of base world transform
(serialize the quaternion, not the converted 3x3 matrix)
There are still several caches not taken into account, and btMultiBody links/constraints are not deserialized yet etc.
See examples\pybullet\examples\saveRestoreState.py for an example.

81146a4090 pybullet: move RGB,depth, segmentation mask preview windows to the right 
remove some dead code from PhysicsServerCommandProcessor.cpp
 2017-11-18 13:21:20 -08:00
erwincoumans
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)

a57c7e7fcf Fixed setting of m_userConstraintResultArgs (not sure how it ever worked for anyone). It was filling up the userConstraintData with stale memory. 2017-10-08 21:31:29 -07:00

26d32f2aa8 improve loading performance of large textures: 
option to disable tinyrenderer, use p.configureDebugVisualizer(p.COV_ENABLE_TINY_RENDERER,0)
also make sure to use p.configureDebugVisualizer(p.COV_ENABLE_RENDERING,0) before loadURDF, and enable rendering afterwards using p.configureDebugVisualizer(p.COV_ENABLE_RENDERING,1)
reorder 2 loops, making the flip texels twice as fast (cache coherency),
single memcpy of entire texture in tinyrenderer, instead of per-pixel copy (memory layout is the same)
add lots of B3_PROFILE timings, to see where time is going

acbe457d31 add option to statically link a plugin, select the postFix (to avoid naming conflict of multiple plugins functions ('initPlugin' becomes initPlugin_postFix) 
pass events (keyboard, mouse, vr controllers etc) to the plugin, and clear them after the tick callback, so that it doesn't interfere with Python 'getEvents'

ee30ca93c5 [sharedmemory] Fill-out calculateJacobian command. 
The server command processor actually didn't do anything with
the local point that was passed along with the calculateJacobian
command. Added in the necessary bit of math to return the
corresponding jacobian.

Also, fixed a typo in pybullet that was returning the same
jacobian for translation and rotation.
