appLineCheckTriangle()

FORCEINLINE bool appLineCheckTriangle	(	const FVector4 &	Start,
		const FVector4 &	End,
		const FVector4 &	Dir,
		const FVector4 &	V0,
		const FVector4 &	V1,
		const FVector4 &	V2,
		const FVector4 &	Normal,
		float &	IntersectionTime
	)

Line vs triangle intersection test.

Parameters

Start	Start of the line segment
End	End of the line segment
Dir	Direction of the line segment (not normalized, just End-Start)
V0	First vertex of the triangle
V1	Second vertex of the triangle
V2	Third vertex of the triangle
Normal	Triangle normal (including +W for the plane equation)
IntersectionTime	[in/out] Best intersection time so far (0..1), as in: IntersectionPoint = Start + IntersectionTime * Dir.

Returns

true if the line intersected the triangle
