Syntax

template<typename COLL_DATA_PROVIDER, typename KDOP_IDX_TYPE>
struct TkDOPLineCollisionCheck :
public TkDOPCollisionCheck< COLL_DATA_PROVIDER, KDOP_IDX_TYPE >,
public TkDOPCollisionCheck< COLL_DATA_PROVIDER, KDOP_IDX_TYPE >

Remarks

This struct holds the information used to do a line check against the kDOP tree. The collision provider gives access to various matrices, vertex data etc. without having to use virtual functions.

Variables

	Name	Description
const bool	bFindClosestIntersection	Flags for optimizing a trace
FVector3SOA	DirSOA	Direction of the line (not normalized, just EndSOA-StartSOA), where each component is replicated into their own vector registers.
const FVector4 ...	End
FVector3SOA	EndSOA	End of the line, where each component is replicated into their own vector registers.
KDOP_IDX_TYPE	HitNodeIndex	Index into the kDOP tree's nodes of the node that was hit.
FVector4	LocalDir
FVector4	LocalEnd
FVector4	LocalHitNormal	Normal in local space which gets transformed to world at the very end.
FVector4	LocalOneOverDir
FVector4	LocalStart	Locally calculated vectors.
FkHitResult ...	Result	Where the collision results get stored
const FVector4 ...	Start	Constant input vars.
FVector3SOA	StartSOA	Start of the line, where each component is replicated into their own vector registers.

Constructors

	Name	Description
	TkDOPLineCollisionCheck ( const FVector4& InStart, const FVector4& InEnd, bool bInbFindClosestIntersection, const COLL_DATA_PROVIDER& InCollDa..., FkHitResult* InResult )	Sets up the FkDOPLineCollisionCheck structure for performing line checks against a kDOPTree.
	TkDOPLineCollisionCheck ( const FVector4& InStart, const FVector4& InEnd, bool bInbFindClosestIntersection, const COLL_DATA_PROVIDER& InCollDa..., FkHitResult* InResult )	Sets up the FkDOPLineCollisionCheck structure for performing line checks against a kDOPTree.

Functions

		Name	Description
	FVector4	GetHitNormal()	Transforms the local hit normal into a world space normal using the transpose adjoint and flips the normal if need be
	FVector4	GetHitNormal()	Transforms the local hit normal into a world space normal using the transpose adjoint and flips the normal if need be
