Classes

	Name	Description
	FLinearIntersection	FLinearIntersection contains intersection information returned by linear/primitive intersection functions
	TIntersector1	TIntersector1 computes the intersection of one-dimensional intervals [u0,u1] and [v0,v1].
	TIntrLine2Line2	Compute intersection between two 2D lines
	TIntrLine2Triangle2	Compute intersection between 2D Line and 2D Triangle
	TIntrRay3AxisAlignedBox3	Compute intersection between 3D ray and 3D axis-aligned box
	TIntrRay3Triangle3	Compute intersection between 3D ray and 3D triangle
	TIntrSegment2Segment2	Ported from WildMagic5
	TIntrSegment2Triangle2	Compute intersection between 2D segment and 2D triangle
	TIntrTriangle2Triangle2	Compute intersection between 2D triangles
	TIntrTriangle3Triangle3	Compute intersection between 3D triangles use Test() for fast boolean query, does not compute intersection info use Find() to compute full information By default fully-contained co-planar triangles are not reported as intersecting.
