Option to de/serialize btPersistentContactManifolds and fix lossy conversion during btMultiBody de/serialization of base world transform
(serialize the quaternion, not the converted 3x3 matrix)
There are still several caches not taken into account, and btMultiBody links/constraints are not deserialized yet etc.
See examples\pybullet\examples\saveRestoreState.py for an example.
For OSX:
cd build
./premake_osx xcode4
for iOS:
cd build
./ios_build.sh
./ios_run.sh
Also integrated the branches/StackAllocation to make it easier to multi-thread collision detection in the near future. It avoids changing the btCollisionObject while performing collision detection.
As this is a large patch, some stuff might be temporarily broken, I'll keep an eye out on issues.
void btCollisionWorld::contactPairTest(btCollisionObject* colObjA, btCollisionObject* colObjB, ContactResultCallback& resultCallback)
cmake: improve feedback for Maya Plugin handling if the Maya base path is not detected
The user should derive its own class from ContactResultCallback and implement the following callback (similar to the gContactAddedCallback):
virtual btScalar addSingleResult(btManifoldPoint& cp, const btCollisionObject* colObj0,int partId0,int index0,const btCollisionObject* colObj1,int partId1,int index1) = 0;
move debugDrawWorld to btCollisionWorld.
improved CollisionInterfaceDemo, show how to perform a closest point query for objects that are not in the collision world.
removed a bit of garbage from the debug drawer
+ use default convex drawing instead of special cylinder drawing (caps are wrongly drawn)
+ allow camera translation using middle-mouse button in SoftDemo
+ add/removeCollisionObject virtual
Thanks Ola for this suggestion
Usage: set RayResultCallback.m_flags to kF_FilterBackfaces, optionally combined with kF_KeepUnflippedNormal.
Thanks Andy O'Neil for the patch!
Remove the force_inline for some internal constraint solver methods, it makes re-use easier.
Workaround/avoid MSVC 2005 compiler error in LibXML/trionan.c
It is a fast way to keep track of overlapping objects in an area, and doing rayTest and convexSweepTest for overlapping objects, instead of btCollisionWorld::rayTest/convexSweepTest.
Updated KinematicCharacterController to use btPairCachingGhostObject.
rename AddSingleResult to addSingleResult
moved collision filtering for btCollisionWorld::rayTest and btCollisionWorld::convexSweepTest from argument to the callback needsCollision
+ improved btSubsimplexConvexCast, btContinuousConvexCollision and btGjkConvexCast to support configuration that start in touching/penetration, required for 'sliding'.
+ added files to CMakeLists.txt for CharacterController
+ bump up version to 2.70 (preparation for beta)
Some dynamic memory allocations have been replace by pool allocation or stack allocations.
quantized aabb versus quantized aabb overlap check is made branch-free (helps a lot on consoles PS3/XBox 360)
Collision algorithms are now created through a new btDefaultCollisionConfiguration, to decouple dependency (this is the API change):
Example:
btDefaultCollisionConfiguration* collisionConfiguration = new btDefaultCollisionConfiguration();
m_dispatcher = new btCollisionDispatcher(collisionConfiguration);
It leads to problems with certain compilers, when Bullet/src is located in a long pathname.
Keep include path starting with "LinearMath/, "BulletCollision/, or "BulletDynamics/
btCollisionWorld.h line 139 (version 2.48) it reads:
m_localShapeInfo(m_localShapeInfo),
which should be:
m_localShapeInfo(localShapeInfo),
Thanks frinkiac8
