25c5e87dc2 PyBullet.loadURDF, expose flags=URDF_INITIALIZE_SAT_FEATURES 2018-06-13 15:35:56 -07:00
erwincoumans
97c6937388 Simplify GJK. Still needs double precision for large differences of feature scales. 
Extract faces directly from btConvexHullComputer (in initializePolyhedralFeatures), instead of reconstructing them, thanks to Josh Klint in #1654
PyBullet: use initializePolyhedralFeatures for convex hulls and boxes (to allow SAT)
PyBullet: expose setPhysicsEngineParameter(enableSAT=0 or 1) to enable Separating Axis Test based collision detection for convex vs convex/box and convex versus concave triangles (in a triangle mesh).

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.

26d32f2aa8 improve loading performance of large textures: 
option to disable tinyrenderer, use p.configureDebugVisualizer(p.COV_ENABLE_TINY_RENDERER,0)

single memcpy of entire texture in tinyrenderer, instead of per-pixel copy (memory layout is the same)
