bc51ac3f0f Support getCachedReturnData for PhysicsLoopBack 
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.

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

1e8f39b492 improve premake4 build in case X11 headers are missing 
improve video_sync_mp4.py example
allow to create a heightfield from file or programmatically in C++ robotics api. Example:

{
		b3RobotSimulatorCreateCollisionShapeArgs shapeArgs;
		shapeArgs.m_shapeType = GEOM_HEIGHTFIELD;
		bool useFile = true;
		if (useFile)
		{
			shapeArgs.m_fileName = "D:/dev/bullet3/data/heightmaps/gimp_overlay_out.png";
			shapeArgs.m_meshScale.setValue(.05, .05, 1);
		}
		else
		{
			shapeArgs.m_numHeightfieldColumns = 256;
			shapeArgs.m_numHeightfieldRows = 256;
			shapeArgs.m_meshScale.setValue(.05, .05, 1);
			shapeArgs.m_heightfieldData.resize(shapeArgs.m_numHeightfieldRows * shapeArgs.m_numHeightfieldColumns);
			double heightPerturbationRange = 0.05;
			for (int j = 0; j<int(shapeArgs.m_numHeightfieldColumns / 2); j++)
			{
				for (int i = 0; i < (int(shapeArgs.m_numHeightfieldRows / 2)); i++)
				{
					double height = ((double)rand() / (RAND_MAX)) * heightPerturbationRange;
					shapeArgs.m_heightfieldData[2 * i + 2 * j * shapeArgs.m_numHeightfieldRows] = height;
					shapeArgs.m_heightfieldData[2 * i + 1 + 2 * j * shapeArgs.m_numHeightfieldRows] = height;
					shapeArgs.m_heightfieldData[2 * i + (2 * j + 1) * shapeArgs.m_numHeightfieldRows] = height;
					shapeArgs.m_heightfieldData[2 * i + 1 + (2 * j + 1) * shapeArgs.m_numHeightfieldRows] = height;
				}
			}
		}
		int shape = sim->createCollisionShape(shapeArgs.m_shapeType, shapeArgs);
		b3RobotSimulatorCreateMultiBodyArgs bodyArgs;
		bodyArgs.m_baseCollisionShapeIndex = shape;
		int groundId = sim->createMultiBody(bodyArgs);
		int texId = sim->loadTexture(shapeArgs.m_fileName);
		b3RobotSimulatorChangeVisualShapeArgs args;
		args.m_objectUniqueId = groundId;
		args.m_linkIndex = -1;
		args.m_textureUniqueId = texId;
		sim->changeVisualShape(args);

caa8b26ce5 Fixes in TinyAudio, play sound on collision impact, can be configured in URDF/SDF file. 
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.)

c517c434e6 pybullet allow to enable/change joint limits: 
pybullet.changeDynamicsInfo(objectUniqueId, linkIndex, jointLowerLimit=..., jointUpperLimit=...) # jointLowerLimit <= jointUpperLimit

and joint limit max force:
pybullet.changeDynamicsInfo(objectUniqueId, linkIndex, jointLimitForce=...)

For example:
p.changeDynamics(sphereUid,linkIndex, jointLowerLimit=1, jointUpperLimit=3, jointLimitForce=10.5)

add b3ChangeDynamicsInfoSetJointLimit/b3ChangeDynamicsInfoSetJointLimitForce
add getConstraintType for btMultiBodyConstraint
