e97b751781 further work on urdfEditor.py, fix some serialization issues 2018-01-08 12:25:56 -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

4743d2770a fix recently introduced crashing bug in MJCF reader 
due to https://github.com/bulletphysics/bullet3/pull/1484 (Issue 1484)

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

97547eda0d preliminary work towards saveState/restoreState and saveRestoreState.py example (not implemented yet)

eb35cba740 expose local inertia diagonal in C-API, PyBullet, through the 'getDynamicsInfo' 
render the inertia boxes in examples/pybullet/examples/quadruped.py and examples/pybullet/examples/reset_dynamic_info.py
fix an issue where the original margin (0.04) was used to compute the inertia, instead of latest margin

cec8da3d85 Implement first draft of pybullet.createVisualShape and add createVisualShape.py example 
add normals to duck.obj for nicer appearance

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

eb97e06280 fix minitaur.urdf: move lower-leg inertia to center, add missing collision for one of the motors, add contact parameters for friction_anchor, spinning friction, compliance (stiffness/damping) 
fix in indexing for maximal coordinates (unused by default, still experimental, requires many iterations for Minitaur due to extreme mass-ratio, hence use of reduces/generalized coordinates)
modify quadruped.py to test maximal coordinates
wrap angular servo (positional) target within [-PI,PI] in btGeneric6DofSpring2Constraint
add 'j' key to show body frames in wireframe/debug mode
