Note: ColladaConverter will export a btGImpactConvexDecompositionShape the same as a btCompoundShape, so importing an exported btGImpactConvexDecompositionShape (roundtrip) creates a btCompoundShape
Please see HfFluidDemo.cpp for examples of how to use the height field fluid along with buoyant collision shapes.
The implementation is still lacking in my ways:
1) Need to complete more collision algorithms for buoyant collision shapes
2) Support compound buoyant shapes
3) The buoyancy model isn't that great
4) Fluid volume can be lost over time
Thanks to Ole for reporting
Fix a bug , causing some deep penetrations to be missed. Not likely to have impacted many users, as such deep penetrations should have prevented in the first place.
Thanks a lot to Andy O'Neil for reporting and reproduction case.
1) Add fast branchless SIMD support for constraint solver (Windows only until we get other contributions).
See resolveSingleConstraintRowGenericSIMD in Bullet/src/BulletDynamics/ConstraintSolver/btSequentialImpulseConstraintSolver.cpp
resolveSingleConstraintRowGenericSIMD can be used for all constraints, including contact, point 2 point, hinge, generic etc.
2) During this refactoring, all constraints support the obsolete 'solveConstraintObsolete' while we add 'getInfo1' and 'getInfo2' support.
This interface is almost identical interface to Open Dynamics Engine, to make it easier to port Dantzig LCP solver.
3) Some minor refactoring to reduce huge constructor overhead in math classes.
Add Concave Convexcast demo back in AllBulletDemos, and tweaked it a bit.
Fix view frustum of ForkLiftDemo (caused picking to fail)
Removed innerloop profiling for ray and convex casts, it hurts performance.
Set default #aabb's in CDTestFramework to 8192
1) creating a broadphase proxy -> adding pairs during insertion. But during this pair insertion, the btGhostObject broadphase handle isn't set yet (it is done in step 2)
2) assign the broadphase proxy to btGhostObject
Thanks to ihar3d for the report http://bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2864
Fix issues with btDbvt: use ATTRIBUTE_ALIGNED16
Removed several places where variable was declared within for statement: for (int i=0; should be int i; for (i=0
Disable libxml LIBXML_MODULE_EXTENSION
Fixed include path in btConeTwistConstraint (it should be relative to src folder, not using ../../ )
Thanks to ejtttje, http://code.google.com/p/bullet/issues/detail?id=129
Don't create a todo list for doxygen by default (the chaotic todo's would confuse most developers)
Improve support for small objects, by having dynamic contact breaking thresholds. Still needs small internal timestep and some GJK improvements.
Add CMake install support for libbulletmath,libbulletcollision,libbulletdynamics,libbulletsoftbody,and toplevel include files
Options to enable/disable BUILD_DEMOS and BUILD_ETRAS
Fixed compile issue in BulletMultiThreaded
Fixed double-precision issues with btMatrix3x3::getEulerZYX
Fixed recently introduced issue: can't re-use stack as member variable (to reduce memory allocs) in btDbvt, due to recursion.
remove btGjkEpa.* from Makefile.am, Makefile and CMakeLists.txt
avoid division-by-zero in ODE boxbox contact reduction
