1bd82e7d81 allow rendering of (textured) heightfield in TinyRenderer and EGL. 
Also update normals, if heightfield is updated.

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.)

d88d0e92ef also update m_jointLowerLimit/m_jointUpperLimit in multibody link. 2020-07-07 19:49:29 -07:00
Erwin Coumans
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
