df89ce6f92 small refactor of LinkVisualShapesConverter / TinyRendererVisualShapeConverter, it allows to use it in a Python module and in a PyBullet plugin. 2018-01-16 17:58:19 -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.

fdd517e00f First step towards a MuJoCo MJCF importer for Bullet. It can load the humanoid.xml, ant.xml and some other OpenAI GYM asset files. Not all fields are converted, so it is work-in-progress. This is useful for Reinforcement Learning experiments, and would also help integration with DeepMind Lab. 2016-12-30 18:32:57 -08:00
