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)

d5f5ddf2f1 Bullet debug draw added
It is off by default, see attributes of dSolverNode to turn it on

e459145b91 Crash bug when "mesh" applied twice fixed
Constraints reworked - all of them could now work with one or two bodies

Modification of constraint frames and initial positions of rigid bodies
now allowed at start frame only

Plugin version is set to 2.76

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

d67aa861f2 Add support for childshape index for btCompoundShape during ContactAddedCallback,
see example in Bullet/Demos/ConvexDecompositionDemo
Removed some warnings

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
Thanks linzner http://code.google.com/p/bullet/issues/detail?id=260

d9c4529a26 + bugfix in btAlignedObjectArray, not calling destructors on resize to smaller array.
Thanks Benoit for pointing this out, and bugfix: http://code.google.com/p/bullet/issues/detail?id=218

+ Added point to point, hinge, slider and generic 6dof constraints to Maya Dynamica plugin
Thanks to Herbert Law for the constribution: http://code.google.com/p/bullet/issues/detail?id=221

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
