Member Function Documentation

static float csSquaredDist::PointLine	(	const csVector3 &	p,
		const csVector3 &	l1,
		const csVector3 &	l2
	)			[static]

Returns the squared distance between a point and a line.

static float csSquaredDist::PointPlane	(	const csVector3 &	p,
		const csPlane3 &	plane
	)			[inline, static]

Returns the squared distance between a point and a normalized plane.

Definition at line 243 of file math3d.h.

static float csSquaredDist::PointPoint	(	const csVector3 &	p1,
		const csVector3 &	p2
	)			[inline, static]

Returns the squared distance between two points.

Definition at line 232 of file math3d.h.

static float csSquaredDist::PointPoly	(	const csVector3 &	p,
		csVector3 *	V,
		int	n,
		const csPlane3 &	plane,
		float	sqdist = -1
	)			[static]

Returns the squared distance between a point and a polygon.

If sqdist is >= 0, then it is used as the pre-calculated point to plane distance. V is an array of vertices, n is the number of vertices, and plane is the polygon plane.
