Constructor & Destructor Documentation

◆ BoxedLcpConstraintSolver() [1/4]

dart::dynamics::BoxedLcpConstraintSolver::BoxedLcpConstraintSolver	(	double	timeStep,
		BoxedLcpSolverPtr	boxedLcpSolver = `nullptr`,
		BoxedLcpSolverPtr	secondaryBoxedLcpSolver = `nullptr`
	)

Constructor.

Parameters

[in]	timeStep	Simulation time step
[in]	boxedLcpSolver	The primary boxed LCP solver. When nullptr is passed, Dantzig solver will be used.
[in]	secondaryBoxedLcpSolver	The secondary boxed-LCP solver. When nullptr is passed, PGS solver will be used. This is to make the default solver setting to be Dantzig + PGS. In order to disable use of secondary solver, call setSecondaryBoxedLcpSolver(nullptr) explicitly.

Deprecated:: Deprecated in DART 6.8. Please use other constructors that doesn't take timespte. Timestep should be set by the owner of this solver such as dart::simulation::World when the solver added.

◆ BoxedLcpConstraintSolver() [2/4]

dart::dynamics::BoxedLcpConstraintSolver::BoxedLcpConstraintSolver ( )

Constructos with default primary and secondary LCP solvers, which are Dantzig and PGS, respectively.

◆ BoxedLcpConstraintSolver() [3/4]

dart::dynamics::BoxedLcpConstraintSolver::BoxedLcpConstraintSolver ( BoxedLcpSolverPtr boxedLcpSolver )

Constructors with specific primary LCP solver.

Parameters

[in] boxedLcpSolver The primary boxed LCP solver. When nullptr is passed, which is discouraged, Dantzig solver will be used.

◆ BoxedLcpConstraintSolver() [4/4]

dart::dynamics::BoxedLcpConstraintSolver::BoxedLcpConstraintSolver	(	BoxedLcpSolverPtr	boxedLcpSolver,
		BoxedLcpSolverPtr	secondaryBoxedLcpSolver
	)

Constructs with specific primary and secondary LCP solvers.

Parameters

[in]	boxedLcpSolver	The primary boxed LCP solver. When nullptr is passed, which is discouraged, Dantzig solver will be used.
[in]	secondaryBoxedLcpSolver	The secondary boxed-LCP solver. Pass nullptr to disable using secondary LCP solver.
