Produce a set of particles and their shapes that overlap the query bounds and pass the particle and shape filters.

@TParam TParticleFilter a particle that returns true to check a particle for overlaps. Signature bool(const FGeometryParticleHandle*)

@TParam TShapeFilter a shape that returns true to check a particle for overlaps. Signature bool(const FPerShapeData*, const FImplicitObject*)

◆ SimSweepParticle()

		const FVec3 &	StartPos,
		const FRotation3 &	Rot,
		const FVec3 &	Dir,
		const FReal	Length,
		TParticleFilter &	ParticleFilter,
		TShapeFilter &	ShapeFilter,
		THitCollector &	HitCollector
	)

Sweep a particle against all other particles that it may hit. The particles are visited in a semi-random order, depending on how the particles are held in the spatial acceleration. The provided filter policies can be used to reject particle pairs or shape pairs. The collector policy chooses which sweep result(s) to keep.

Template Parameters

TParticleFilter A custom filter functor with the signature bool(const FGeometryParticleHandle* SweptParticle, const FGeometryParticleHandle* OtherParticle) used to accept/reject particle pairs. It should return true if the particle pair should be considered for a sweep check.

See also: FSimSweepParticleFilterBroadPhase which provides the standard broadphase filter used in collision detection.

Template Parameters

TShapeFilter A custom filter functor with the signature bool(const FPerShapeData* SweptShape, const FImplicitObject* SweptImplicit, const FPerShapeData* OtherShape, const FImplicitObject* OtherImplicit) used to accept/reject shapes pairs. It should return true if the pair should be considered for a sweep check.

See also: FSimSweepShapeFilterNarrowPhase which provides the standard narrowphase filter used in collision detection.

Template Parameters

THitCollector A hit collector functor with signature bool(const FVec3& Dir, const FReal Length, const FSimSweepParticleHit& InHit). It should return true to continue checking further objects, or false to stop any further sweeping.

See also: FSimSweepCollectorFirstHit which keeps the hit with the lowest time of impact and the most opposing normal if there is a tie.

Parameters

SweptParticle	The particle to be swept
StartPos	The start position of the particle to be swept
Rot	The rotation to use for the sweep
Dir	The direction of the sweep (must be normalized)
Length	The sweep length
ParticleFilter	The filter to use to accept/reject particle pairs
ShapeFilter	The filter to use to accept/reject shape pairs within the particle pairs
HitCollector	Hits are passed to the collector one at a time in a semi-random order (i.e., they are not sorted by TOI)

◆ SimSweepParticleFirstHit()

bool Chaos::Private::SimSweepParticleFirstHit	(	ISpatialAcceleration< FAccelerationStructureHandle, FReal, 3 > *	SpatialAcceleration,
		FIgnoreCollisionManager *	IgnoreCollisionManager,
		const FGeometryParticleHandle *	SweptParticle,
		const FVec3 &	StartPos,
		const FRotation3 &	Rot,
		const FVec3 &	Dir,
		const FReal	Length,
		FSimSweepParticleHit &	OutHit,
		const FReal	InHitDistanceEqualTolerance = `UE_KINDA_SMALL_NUMBER`
	)

Sweep a particle to find the first impact with another particle that the particle would normally collide with according to the sim filter data on the particles.

Parameters

SpatialAcceleration	The spatial acceleration structure used in the broadphase
IgnoreCollisionManager	The ignore collision manager used in the main broadphase (or null)
SweptParticle	The particle to be swept
StartPos	The start position of the particle to be swept
Rot	The rotation to use for the sweep
Dir	The direction of the sweep (must be normalized)
Length	The sweep length
OutHit	Output set to the first hit if there was one, otherwise invalidated.

Returns: true if there was a hit, otherwise false

Note: This call SimSweepParticle with the FSimSweepParticleFilterCollidable and FSimSweepShapeFilterCollidable filter policies, and the FSimSweepCollectorFirstHit hit collector. If these policies are not what you want, you can create your own policies and/or collector (e.g., to collect all hits) and use SimSweepParticle directly.

◆ SimSweepParticlePair()

template<typename TShapeFilter , typename THitCollector >

void Chaos::Private::SimSweepParticlePair	(	const FGeometryParticleHandle *	SweptParticle,
		const FGeometryParticleHandle *	OtherParticle,
		const FVec3 &	StartPos,
		const FRotation3 &	Rot,
		const FVec3 &	Dir,
		const FReal	Length,
		TShapeFilter &	ShapeFilter,
		THitCollector &	HitCollector
	)

Sweep SweptParticle against OtherParticle. The provided filter policy can be used to reject shape pairs. The collector policy chooses which sweep results(s) to keep.

Template Parameters

TShapeFilter A custom filter functor with the signature bool(const FPerShapeData* SweptShape, const FImplicitObject* SweptImplicit, const FPerShapeData* OtherShape, const FImplicitObject* OtherImplicit) used to accept/reject shapes pairs. It should return true if the pair should be considered for a sweep check.

See also: FSimSweepShapeFilterNarrowPhase which provides the standard narrowphase filter used in collision detection.

Template Parameters

THitCollector A hit collector functor with signature bool(const FVec3& Dir, const FReal Length, const FSimSweepParticleHit& InHit). It should return true to continue checking further objects, or false to stop any further sweeping.

See also: FSimSweepCollectorFirstHit which keeps the hit with the lowest time of impact and the most opposing normal if there is a tie.

Parameters

SweptParticle	The particle to be swept
OtherParticle	The particle to be swept against
StartPos	The start position of the particle to be swept
Rot	The rotation to use for the sweep
Dir	The direction of the sweep (must be normalized)
Length	The sweep length
ShapeFilter	The filter to use to accept/reject shape pairs within the particle pairs
HitCollector	Hits are passed to the collector one at a time in a random order (i.e., they are not sorted by TOI)

Note: This function does not reset the HitCollector.
