Use btSetCustomEnterProfileZoneFunc(CProfileManager::Start_Profile) and
btSetCustomLeaveProfileZoneFunc(CProfileManager::Stop_Profile) to get old behavior.
error_message and warning_message are common strings that are likely to
collide. Renamed to bt_id_{error,warning}_message to more strongly
uniquify.
grep -r error_message -l src/BulletInverseDynamics | \
xargs sed -i -e "s/error_message/bt_id_error_message/g"
grep -r warning_message -l src/BulletInverseDynamics | \
xargs sed -i -e "s/warning_message/bt_id_warning_message/g"
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;
- 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.
(and issue with TaskScheduler/btTaskScheduler.cpp, add JobQueue::exit, call it first, since it uses the m_threadSupport which was deleted before the destrucor was called.
Use a hashmap to store user timers, to avoid allocating many identical strings.
reduce 'm_cooldownTime' from 1000 microseconds to 100 microseconds (overhead in raycast is too large)
If needed, we can expose this cooldown time.
Replace malloc by btAlignedObjectArray (going through Bullet's memory allocator)
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).
return Py_None if no user data found, to pass the test.
enable m_deterministicOverlappingPairs by default.
if m_deterministicOverlappingPairs, sort the collision pairs.
Adds unit test for the UserData functons.
Changes the char pointer in btHashString to std::string. There were
problems where the object owning the string memory would deallocate the
string, making the btHashString object invalid.
