◆ GetAABB()

bool chrono::collision::ChCollisionSystemMulticore::GetAABB	(	real3 &	aabbmin,
		real3 &	aabbmax
	)

Get the dimensions of the "active" box.

The return value indicates whether or not the active box feature is enabled.

◆ RayHit() [1/2]

virtual bool chrono::collision::ChCollisionSystemMulticore::RayHit	(	const ChVector<> &	from,
		const ChVector<> &	to,
		ChCollisionModel *	model,
		ChRayhitResult &	mresult
	)		const

inlineoverridevirtual

Perform a ray-hit test with the specified collision model.

Currently not implemented.

Implements chrono::collision::ChCollisionSystem.

◆ RayHit() [2/2]

virtual bool chrono::collision::ChCollisionSystemMulticore::RayHit	(	const ChVector<> &	from,
		const ChVector<> &	to,
		ChRayhitResult &	mresult
	)		const

inlineoverridevirtual

Perform a ray-hit test with all collision models.

Currently not implemented.

Implements chrono::collision::ChCollisionSystem.

◆ Remove()

void chrono::collision::ChCollisionSystemMulticore::Remove ( ChCollisionModel * model )

overridevirtual

Remove a collision model from the collision engine.

Currently not implemented.

Implements chrono::collision::ChCollisionSystem.

Reimplemented in chrono::collision::ChCollisionSystemDistributed.

◆ ReportProximities()

virtual void chrono::collision::ChCollisionSystemMulticore::ReportProximities ( ChProximityContainer * mproximitycontainer )

inlineoverridevirtual

Implements chrono::collision::ChCollisionSystem.

◆ SetAABB()

void chrono::collision::ChCollisionSystemMulticore::SetAABB	(	real3	aabbmin,
		real3	aabbmax
	)
