9141caf67e Add joint limit example. 
The demo artifically exceeds joint limit due to numerical errors caused
by large ratio.

5d60c274c4 Add an example of a stack of boxes of large mass ratio. The default 
solver cannot solve it effectively.

fast createMultiBody batch creation, more deep_mimic work
 2019-02-12 12:10:10 -08:00
erwincoumans
85ee4c2934 allow batch creation of objects through PyBullet.createMultiBody, see createMultiBodyBatch.py example. 
expose minGraphicsUpdateTimeMs through PyBullet.connect(p.GUI, options="minGraphicsUpdateTimeMs=32000"), by default OpenGL rendering runs at 4000microseconds intervals.
allow a maximum of 128k objects
fix meshScale for PyBullet.createCollisionShape for custom mesh
expose Pybullet.setPhysicsEngineParameter(minimumSolverIslandSize=...), larger minimum batches group solver constraints together in the same island, to reduce calling overhead (even if they are not related)

erwincoumans
9bddca873c allow pybullet_envs.deep_mimic.testrl --arg_file run_humanoid3d_backflip_args.txt to perform a backflip. Can only backflip twice, then drops on ground. 
this deepmimic is still very slow, due to slow mass matrix/inverse dynamics computation. once spherical motor drive is enabled, it should be fast(er)
move pd_controller_stable to pybullet_utils for easier re-use
add plane_transparent.urdf to pybullet_data
allow spacebar in keyboardEvents (Windows for now)

9553892770 PyBullet / BulletRobotics: 
Implement collisionFilterPlugin, use setCollisionFilterPair to enable or disable collision detection between specific pairs of objects.
Also, expose setCollisionFilterGroupMask as PyBullet API and in urdf using the tag <collision group="1" mask="2"/>.
See examples/pybullet/examples/collisionFilter.py for an example.
PyBullet default: Lower the warmstarting factor, for maximal coordinates rigid bodies for more stable simulation.
Add btCollisionWorld::refreshBroadphaseProxy to easier recreate the broadphase proxy without adding/removing objects to the world.

0efc67841d allow pybullet to connect to GRPC server. (need to use flag --enable_grpc in premake build system) 
add grpcPlugin, it can work in GUI, SHARED_MEMORY_SERVER, DIRECT and other modes.
example script to start server from pybullet:
import pybullet as p
p.connect(p.GUI)
#if statically linked plugin
id = p.loadPlugin("grpcPlugin")
#dynamics loading the plugin
#id = p.loadPlugin("E:/develop/bullet3/bin/pybullet_grpcPlugin_vs2010_x64_debug.dll", postFix="_grpcPlugin")

#start the GRPC server at hostname, port
if (id>=0):
	p.executePluginCommand(id, "localhost:1234")

Only in DIRECT mode, since there is no 'ping' you need to call to handle RCPs:
numRPC = 10
while (1):
	p.executePluginCommand(id, intArgs=[numRPC])

c062bfc2d5 Removes visual shape data when a body gets removed. 
Problem description:
When you add a body, remove it and then add a new
body, the body id may be reused by Bullet.
Because the visual shape data was not being removed when a body was
removed, requesting the visual shape data for a 'recycled' body id
results in both the visual shape data of the new body as well as the old
one.
Removing the visual shape data when the body gets removed fixes this.

Changes the btAlignedObjectArray for visual shapes to a hashmap, so
that removing is faster. Additionally, functions like getNumVisualShape
don't perform a linear search anymore.

b5495e789d Change constraint solver threshold-based termination condition on residual of velocity threshold, not on residual of impulse threshold. 
This avoids issues with systems with large mass ratios.

Test: add this to BasicDemo/BasicExample.cpp in initPhysics

	m_dynamicsWorld->getSolverInfo().m_numIterations = 1000;
	m_dynamicsWorld->getSolverInfo().m_leastSquaresResidualThreshold = 1e-4;

9c7aa3a863 Changes UserData to use global identifiers and makes linkIndex optional. 
This removes the need to specify the body id/link index when retrieving a user data entry.
Additionally, user data can now optionally be set to visual shapes as well.

The following public pybullet APIs have changed (backwards incompatible)
addUserData and getUserDataId
  Makes linkIndex parameter optional (default value is -1)
  Adds optional visualShapeIndex parameter (default value is -1)

getUserData and removeUserData
  Removes required parameters bodyUniqueId and linkIndex

getNumUserData
  Removes required bodyUniqueId parameter

getUserDataInfo
  Removes required linkIndex parameter
  Changes returned tuple from (userDataId, key) to (userDataId, key, bodyUniqueId, linkIndex, visualShapeIndex)

b84eb8af74 Several fixes for the parallel raycasts 
- Limits the maximum number of threads to 64, since btThreadSupportPosix
and btThreadsupportWin32 don't support more than 64 bits at this moment,
due to the use of UINT64 bitmasks. This could be fixed by using
std::bitset or some other alternative.
- Introduces a threadpool class, b3ThreadPool, which is a simple wrapper
around btThreadSupportInterface and uses this instead of the global task
scheduler for parallel raycasting. This is actually quite a bit faster
than the task scheduler (~10-15% in my tests for parallel raycasts),
since the advanced features (parallelFor) are not necessary for the
parallel raycasts.
- Puts 16*1024 of MAX_RAY_INTERSECTION_MAX_SIZE_STREAMING in
parentheses, since it otherwise causes problems with other operators
of equal precedence and introduces a smaller constant for Apple targets.
- Refactors the parallel raycasts code and adds some more profiling.

08409cae9f Adds multithreading support for batch ray casts. 
To enable the feature, enable the BULLET2_MULTITHREADING option.

Increases the number of rays that can go in a batch request by storing
them in the shared memory stream instead of the shared memory command.
Adds the API b3RaycastBatchSetNumThreads to specify the number of
threads to use for the raycast batch, also adds the argument numThreads
to the pybullet function rayTestBatch.
Rays are distributed among the threads in a greedy fashion there's a shared
queue of work, once a thread finishes its task, it picks the next
available ray from the task. This works better than pre-distributing the
rays among threads, since there's a large variance in computation time per ray.

Some controversial changes:
- Added a pointer to PhysicsClient to the SharedMemoryCommand struct, this
was necessary to keep the C-API the same for b3RaycastBatchAddRay, while
adding the ray to the shared memory stream instead of the command
struct. I think this may be useful to simplify other APIs as well, that
take both a client handle and a command handle.
- Moved #define SHARED_MEMORY_MAX_STREAM_CHUNK_SIZE to
SharedMemoryPublic. This was necessary for the definition of
MAX_RAY_INTERSECTION_BATCH_SIZE.
