62eb2f7788 Disable velocity calculation in kinematic multibody mode by default 
We haven't implemented this for the multi body joints. To be consistent, let's disable it for the base as well, and let user to set the velocities.

re-use existing code path for streaming plugin return data (work-in-progress)
 2020-10-07 08:24:33 -07:00
Erwin Coumans
954ceff2ec Add an option for a plugin to report return data after calling executePluginCommand. Also add python binding. 
Currently the return data has to fit in shared memory, 8MB (Linux, Windows) or 1MB (Apple)
Preparation for streaming is added (to allow unlimited return data, see CMD_CUSTOM_COMMAND_STREAM_RETURN_DATA)

New C-API: b3GetStatusPluginCommandReturnData
PyBullet reports return data if available, in pybullet_executePluginCommand

For the plugin developer:
plugin can provide additional return data for executePluginCommand in the b3PluginContext, during executePluginCommand.
Lifetime of this m_returnData pointer is minimum of next call to the next executePluginCommand or plugin termination.

Add <inertia> for missing links in a1.urdf 
Currently a few collision frames in a1.urdf ("{FL/FR/RL/RR}_upper_shoulder") do not have <inertia> defined, and pybullet loads as if they have 1kg mass. This leads to inaccurate simulation results.

1452cae641 * add textured models of ball.vtk (obj/mtl) and torus (obj/mtl) and cloth. 
1) allow to render deformables in 'getCameraImage', for TinyRenderer (tested OK) and EGL (untested)
2) allow to have textures for deformables. See deformable_ball.py, deformable_anchor.py and deformable_torus.py for examples
3) deformables: allow to request simulation mesh data (even if there is a render mesh) See deformable_anchor.py for an example usage
   data = p.getMeshData(clothId, -1, flags=p.MESH_DATA_SIMULATION_MESH)
4) fix deletion of deformables, thanks to Fychuyan, https://github.com/bulletphysics/bullet3/pull/3048
5) allow to enable and disable double-sided rendering, p.changeVisualShape(objectUid, linkIndex, flags=p.VISUAL_SHAPE_DOUBLE_SIDED)
6) fix GripperGraspExample, model not found
7) Fix deformable anchor not attaching to multibody with object unique id of 0
8) Fix issue with assignment of unique ids in TinyRenderer/EGL renderer (always use broadphase uid)
9) Avoid crash/issue of simulation with pinned vertices (mass 0) in btDeformableBackwardEulerObjective::applyExplicitForce
10) Store uv/normal in btSoftBody::RenderNode to allow textured meshes
11) (uncomment in btSoftBodyHelpers.cpp): dump vertices and indices in obj wavefront format, when loading a VTK file, for quicker creation of a (textured) surface mesh
12) allow interpolateRenderMesh also for old position-based soft bodies (not only the shiny new FEM deformables)
13) fix a few premake targets
14) update build_visual_studio_vr_pybullet_double_cmake.bat so it suits c:\python37 and installs locally
    for local install of Bullet, see also this example https://github.com/erwincoumans/hello_bullet_cmake

Requires a modified setup.py (or use premake4 to compile)

Example script:
import pybullet as p
import time
p.connect(p.GUI)
plane = p.loadURDF("plane_with_collision_audio.urdf")
box = p.loadURDF("cube.urdf",[0,0,1])
p.setGravity(0,0,-10)
while (1):
  p.stepSimulation()
  time.sleep(1./240.)
