329a1f5a74 PyBullet: move TinyRenderer into a plugin, default statically loaded. You can also dynamically load a render plugin, as shown in renderPlugin.py example. premake has a way to compile the tinyRendererPlugin. 2018-01-17 12:48:48 -08:00

79051b7611 allow to use colors from MJCF file as option (default to random Google colors), use p.loadMJCF(filename, flags=p.URDF_MJCF_COLORS_FROM_FILE
fix quadruped.py example.
add PyBullet.isConnected() API, more friendly than PyBullet.getConnectionInfo()["connected"]

22b4809891 leave m_useGlobalVelocities to false, until enabled, for backward compatibility
use URDF_GLOBAL_VELOCITIES_MB flag in PyBullet loadURDF.
fix robot_bases.py due to new fields in getJointInfo.
backward compabitibility: BulletMJCFImporter, keep creating btMultiSphereShape for MJCF capsules with fromto, instead of shifted btCapsuleShapeZ, unless if CUF_USE_IMPLICIT_CYLINDER is used.

Fixes crashes due to rendering of softbody wireframe in the wrong thread (needs to be in 'debug' rendering section)
Use btCapsuleShapeZ instead of btMultiSphereShape when converting MJCF MuJoCo capsules using fromto

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

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

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
