15cda75130 add <restitution> in <contact> settings of URDF/SDF
allow 'useMaximalCoordinates' and 'useFixedBase' in pybullet.loadURDF.
enable split impulse for btRigidBody, even in btMultiBodyDynamicsWorld.
allow initialization of velocity and apply force for btRigidBody in pybullet/shared memory API.
process contact parameters in URDF also for btRigidBody (friction, restitution etc)
add pybullet.setPhysicsEngineParameter with numSolverIterations, useSplitImpulse etc.

2fc0358750 Expose a better API to allow any render engine to be used for the physics simulation when loading URDF/SDF files.
See bullet3/examples/Importers/ImportURDFDemo/DefaultVisualShapeConverter.h
Give the kuka_iiwa/model.urdf some blue color, not just orange, to mimick the original a bit better
Preparation for the CMD_CAMERA_IMAGE_COMPLETED command, to expose a virtual camera to the robotics API

e7bafbc71c make Bullet URDF parser more similar to the ROS URDF parser. There is still a difference in ordering of links,
due to the use of different hash-map implementations, with a difference in iterator order
(btHashMap versus std::hashmap)

d830681674 add option for rigid body/typed constraint to set target velocity
compare joint feedback between multi body and rigid body. initial results are promising (not exactly the same, but reasonably close)
