virtual void GAS_Integrator::getImpulseMassMatrixSubclass	(	const SIM_Object &	object,
		const UT_Vector3 &	impulseworldpos,
		UT_DMatrix3 &	immatrix
	)			const [protected, virtual]

Gets the impulse mass matrix of an object for an impulse at the provided world space position. The default implementation gets the closest point in the geometry and calls getPointImpulseMassMatrix().

Reimplemented from SIM_Solver.

virtual void GAS_Integrator::getPointImpulseMassMatrixSubclass	(	const SIM_Object &	object,
		int	ptnum,
		UT_DMatrix3 &	immatrix
	)			const [protected, virtual]

Gets the impulse mass matrix of an object for an impulse at the provided point on the geometry of the object. The default implementation finds the world space position of the point and calls getImpulseMassMatrix().

Reimplemented from SIM_Solver.

GAS_Integrator::GETSET_DATA_FUNCS_I	(	SIM_NAME_PRIMARYSOLVER	,

virtual bool GAS_Integrator::solveGasSubclass	(	SIM_Engine &	engine,
		SIM_Object *	obj,
		SIM_Time	time,
		SIM_Time	timestep
	)			[inline, protected, virtual]

Applies this subsolver for a single timestep. Returns true on success

Implements GAS_SubSolver.

Definition at line 106 of file GAS_Integrator.h.

virtual SIM_Result GAS_Integrator::solveObjectsSubclass	(	SIM_Engine &	engine,
		SIM_ObjectArray &	objects,
		SIM_ObjectArray &	newobjects,
		SIM_ObjectArray &	feedbacktoobjects,
		const SIM_Time &	timestep
	)			[virtual]

Asks all inputs to compute their forces and integrates them for the given timestep. We may do this several times if a higher-order timestep is used.

Reimplemented from GAS_SubSolver.
