dist()

double RectPatch::dist

(

const Vec3 &

P

)

Get distance from given point to closest point of patch.

Parameters

P

the point

getPlane()

Plane3D RectPatch::getPlane

(

const Vec3 &

intersect()

bool RectPatch::intersect	(	const Vec3 &	P1,
		const Vec3 &	P2
	)

check if line between 2 points intersects patch

Parameters

P1	1st point
P2	2nd point
