Fixes in FractureDemo (mouse picking constraint needs to be removed, otherwise constraint solver crashes/asserts)
Note that it can easily introduce instability at regular (60Hertz) simulation steps so it is generally best to not use the option.
If needed, use a very small internal step, such as 1000 Hertz (world->stepSimulation(dt,100,1./1000.f); or stepSimulation(1./1000.,0);
(make sure to merge islands based on those predictive contacts too, added some check in the solver)
This fixes Issue 356.
Use same solver settings for AllBulletDemos
Make sure to embed the setCcdSweptSphereRadius inside the actual collision shape (for shoot box)
This should improve 'ccd' handling when using world->getDispatchInfo().m_useContinuous = true;body->setCcdSquareMotionThreshold(...); body->setCcdSquareMotionThreshold(...)
shoot smaller boxes (test)
use yellow instead of orange for contact point normals
tweak default erp and erp2 values, now split impulse is on by default (need to check it)
Applied picking cloth patch. Fixes Issue 646. Thanks to Dongsoo.
Applied patch Softbody updateConstraints. Fixes Issue 503. Thanks to Dave Bruce Phillips and Dongsoo.
Fix various warnigns under Mac OSX.
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.
in VoronoiFractureDemo (store intermediate values in memory to avoid problems)
@todo: rewrite the island management to avoid sort for better performance
Thanks to Peter Kyme for the report, fixes Issue 607
fix in infinite recursion in quickSort, exclude the pivot in each sub partition
disabled constraints don't merge simulation islands, and they don't disable collision between linked rigid bodies either.
Fix in btBulletWorldImporter: load friction/restitution and patch radius of btCapsuleShape (it needs to embed the margin)
Partly apply a modified patch to make the SerializeDemo_AMD work, but avoid breaking the MiniCL version. See Issue 594
Rename member numerator to m_numerator in btConvexHullComputer.cpp to avoid confusion (Thanks to Ian for the feedback)
Add btSoftBody::addAeroForceToNode and btSoftBody::addAeroForceToFace, thanks to Dongsoo Han/Saggita
Move btSoftBodySolverData.h to src/BulletMultiThreaded/GpuSoftBodySolvers/Shared/btSoftBodySolverData.h
Attempt to re-enable MiniCL version of OpenCLClothDemo (cloth-capsule collision still broken)
Add optional OpenCL acceleration to SerializeDemo (just for cloth)
