1cd52f3d11 Removed empty constructors for constraints, I don't recall why we added them (possibly SPU) but if we really need them we have to revert this.
Moved static fixed body into a static function 'getFixedBody' to avoid issues when embedding Bullet in C#/CLI managed code.

d58081ce37 Provide easier access to CFM and ERP (and Stop ERP/Stop CFM) for constraints in a similar way to Open Dynamics Engine
virtual	void	btTypedConstraint::setParam(int num, btScalar value, int axis = -1) = 0;
virtual	btScalar btTypedConstraint::getParam(int num, int axis = -1) const = 0;
	
Parameter can be BT_CONSTRAINT_ERP,BT_CONSTRAINT_STOP_ERP,BT_CONSTRAINT_CFM,BT_CONSTRAINT_STOP_CFM
Axis is 0 .. 5, first 3 for linear degrees of freedom, last 3 for angular. If no axis is specified it will take the 'default' degree of freedom. For a btHingeConstraint this would be the hinge axis (5)

0d80aa855e Improved math precision for btHingeConstraint and btSliderConstraint (btAtan2() used instead of btAtan2Fast()) 2009-12-02 00:53:53 +00:00

f919baf03d Improved Slider, Hinge and Generic6DOF constraint setup.
Turned on by default, use m_useOffsetForConstraintFrame = false to use old setup
Use "O" (capital 'o') button to toggle it in SliderConstraintDemo and ConstraintDemo

Total applied impulse copied back from btSolverConstraint to btTypedConstraint

703582f4fa apply fix for btAcosf/btAsinf (numerical issue causes values of X become slightly larger than 1 or smaller than -1, causing NaNs)
manually add some missing files to msvc projectfiles for now
fix in box-box collision detector, preventing it to fail in some rare cases
remove redundant line in btHingeConstraint, thanks to teravus
fix mouse drag camera rotation issue (modulo 360 instead of 180)

5d2cf447e4 Some more minor improvements for PS3 SPU version 2009-08-06 20:03:09 +00:00

3e2529fcb5 Minor constraint refactoring, to allow SPU-side processing for PLAYSTATION 3 (added non-virtual methods)
Also comment-out some code for __SPU__ to reduce code size
Added btContactConstraint (only used on PS3 SPU right now, better to use btPersistentManifold directly for contact constraints)
Improved readblend utility library (see also usage in http://gamekit.googlecode.com with Irrlicht)

Fix for btConvexConvexAlgorithm, potential division by zero

badf723257 Replace all hardcoded 1e30(f) by BT_LARGE_FLOAT, defined in btScalar.h as 1e18(f) so that its square still fits in FLT_MAX

c94cad8cba Added a possibility for btHingeConstraint to use frame of rigid body A as a reference frame at construction time.
It is off by default, so the existing code should work as before

e80feca36b Big work-in-progress refactoring of the constraint solver:
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.

82047e601e updated Bullet sequential impulse constraint solver, so it matches 100% ODE PGS quickstep solver innerloop, mainly by renaming variables... 2008-11-26 00:27:35 +00:00

bcd0f48c28 some doxygen updates, added some comments to classes, fix broken links, rename some prefix some internal GIMPACT collision structures using (for example use GIM_AABB instead of BT_AAABB),
removed obsolete btGjkEpa (it was replaced by btGjkEpa2 ages ago)

ec76f2e0a3 - keep track of all memory allocations (gNumAllignedAllocs/gNumAllignedFree)
All memory allocations in Bullet go through btAlignedAlloc/btAlignedFree

Thanks to Enrico, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1568
- removed SSE includes, added #incude <string.h> for memset in Extras/quickstep, thanks Eternl Knight
- disabled 16-byte alignement on btQuadWord class, it causes problems under PS3 Linux. Need to check out why.

054d672592 - removed STL from the Bullet library: replace std::vector by btAlignedObjectArray. Also removed the std::set for overlapping pair set, and turned it into an overlapping pair array. The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal).
- added heap sort and binary search/linear search to btAlignedObjectArray
- fixed wrong cast, thanks Hamstray, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=1015

bf847b839a another large series of changes, related to the refactoring.
CompoundShapes are tricky to manage with respect to persistent contact points and swapped order of btCollisionObjects,
During dispatch, finding an algorith etc. order can be swapped.
fixed several other issues, related to SimpleBroadphase (removing a proxy was not working)

eb23bb5c0c merged most of the changes from the branch into trunk, except for COLLADA, libxml and glut glitches.
Still need to verify to make sure no unwanted renaming is introduced.
