Detailed Description

template<typename ConstraintContainerType>
class Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >

A constraint solver for use with a simple (non-graph-based) evolution (RBAN) and constraint containers with builtin-in solvers (Joints, Suspension, but not Collisions).

◆ AddBodies()

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::AddBodies ( FSolverBodyContainer &  SolverBodyContainer)
inlinefinaloverridevirtual

Add all the required bodies to the body container (required for the constraints added with AddConstraints)

Implements Chaos::FConstraintContainerSolver.

◆ AddConstraints() [1/2]

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::AddConstraints ( )
inlinefinaloverridevirtual

RBAN API. Add all (active) constraints to the solver.

Implements Chaos::FConstraintContainerSolver.

◆ AddConstraints() [2/2]

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::AddConstraints ( const TArrayView< Private::FPBDIslandConstraint * > &  Constraints)
inlinefinaloverridevirtual

Island API. Add a set of constraints to the solver. This can be called multiple times: once for each island in an IslandGroup, but there will never be more constraints added than specified in Reset(). NOTE: this should not do any actual data gathering - it should just add to the list of constraints in this group. All data gathering is handled in GatherInput.

Implements Chaos::FConstraintContainerSolver.

◆ ApplyPositionConstraints()

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::ApplyPositionConstraints ( const FReal  Dt,
const int32  It,
const int32  NumIts 
)
inlinefinaloverridevirtual

Apply the position solve to all constraints in the container

Implements Chaos::FConstraintContainerSolver.

◆ ApplyProjectionConstraints()

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::ApplyProjectionConstraints ( const FReal  Dt,
const int32  It,
const int32  NumIts 
)
inlinefinaloverridevirtual

Apply the projection solve to all constraints in the container

Implements Chaos::FConstraintContainerSolver.

◆ ApplyVelocityConstraints()

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::ApplyVelocityConstraints ( const FReal  Dt,
const int32  It,
const int32  NumIts 
)
inlinefinaloverridevirtual

Apply the velocity solve to all constraints in the container

Implements Chaos::FConstraintContainerSolver.

◆ GatherInput() [1/2]

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::GatherInput ( const FReal  Dt)
inlinefinaloverridevirtual

Implements Chaos::FConstraintContainerSolver.

◆ GatherInput() [2/2]

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::GatherInput ( const FReal  Dt,
const int32  BeginIndex,
const int32  EndIndex 
)
inlinefinaloverridevirtual

Implements Chaos::FConstraintContainerSolver.

◆ GetNumConstraints()

template<typename ConstraintContainerType >
virtual int32 Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::GetNumConstraints ( ) const
inlinefinaloverridevirtual

Implements Chaos::FConstraintContainerSolver.

◆ Reset()

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::Reset ( const int32  MaxConstraints)
inlinefinaloverridevirtual

Set the maximum number of constraints the solver will have to handle. This will be called only once per tick, so containers resized here will not have to resize again this tick so that pointers to elements in the container will remain valid for the tick (but not beyond).

Implements Chaos::FConstraintContainerSolver.

◆ ScatterOutput() [1/2]

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::ScatterOutput ( const FReal  Dt)
inlinefinaloverridevirtual

Implements Chaos::FConstraintContainerSolver.

◆ ScatterOutput() [2/2]

template<typename ConstraintContainerType >
virtual void Chaos::TSimpleConstraintContainerSolver< ConstraintContainerType >::ScatterOutput ( const FReal  Dt,
const int32  BeginIndex,
const int32  EndIndex 
)
inlinefinaloverridevirtual

Implements Chaos::FConstraintContainerSolver.
