cb6b7a7c38 PyBullet: expose flags to createMultiBody 2018-06-02 11:37:14 -07:00
erwincoumans
edc70582dd implement accurate inverse kinematics in C++. PyBullet.calculateInverseKinematics gets "maxNumIterations=20", "residualThreshold=1.04" to tune 
allow to provide current joint positions in IK, overriding the body joint positions, also IK target will be in local coordinates.
expose b3ComputeDofCount in C-API

77c332bd88 PyBullet: add option to cache graphics shapes for URDF files, handy for benchmarks with many duplicate robots 
See https://github.com/erwincoumans/pybullet_robots ANYmal.py for an example.
PyBullet: Expose p.setPhysicsEngineParameter(solverResidualThreshold=1e-2) (b3PhysicsParamSetSolverResidualThreshold), increases solver performance a lot
PyBullet: Expose p.setPhysicsEngineParameter(contactSlop) Set it to zero, to avoid issues with restitution.
PyBullet: Expose isNumpyEnabled, return True is PyBullet was compiled with NUMPY support for 'getCameraImage'.
PyBullet: Expose p.ChangeDynamics(objectUid, linkIndex, contactProcessingThreshold), to avoid issues of speculative/predictive contacts with restitution.

e5a9b42f9a expose PyBullet.setPhysicsEngineParameter(jointFeedbackMode) 
use p.JOINT_FEEDBACK_IN_JOINT_FRAME if you want the joint feedback expressed in joint frame (instead of link inertial frame)
use p.JOINT_FEEDBACK_IN_WORLD_SPACE if you want the joint feedback in world space coordinates, instead of local link/joint coordinates.
Example: p.setPhysicsEngineParameter(jointFeedbackMode=p.JOINT_FEEDBACK_IN_WORLD_SPACE+p.JOINT_FEEDBACK_IN_JOINT_FRAME)

ddf304ca78 PyBullet: expose internal edge utility, to adjust edge normals to prevent object penetrating along triangle edges of concave triangle meshes 
(due to local convex-triangle collisions causing opposite contact normals, use the pre-computed edge normal)
PyBullet: expose experimental continuous collision detection for maximal coordinate rigid bodies, to prevent tunneling.

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
