Constants
- PLANE_YZ = Plane( 1, 0, 0, 0 )
- PLANE_XY = Plane( 0, 0, 1, 0 )
Plane represents a normalized plane equation. Basically, “normal” is the normal of the plane (a,b,c normalized), and “d” is the distance from the origin to the plane (in the direction of “normal”). “Over” or “Above” the plane is considered the side of the plane towards where the normal is pointing.

Method Descriptions
Creates a plane from the four parameters “a”, “b”, “c” and “d”.
Creates a plane from three points.
- Vector3 center ( )
Returns the center of the plane.
- distance_to ( Vector3 point )
Returns the shortest distance from the plane to the position “point”.
- get_any_point ( )
Returns a point on the plane.
Returns if “point” is inside the plane (by a very minimum threshold).
- intersect_3 ( Plane b, c )
Returns the intersection point of a ray consisting of the position “from” and the direction normal “dir” with this plane. If no intersection is found null is returned.
- intersects_segment ( Vector3 begin, end )
Returns the intersection point of a segment from position “begin” to position “end” with this plane. If no intersection is found null is returned.
- bool is_point_over ( point )
Returns true if “point” is located above the plane.
- Plane normalized ( )
Returns a copy of the plane, normalized.
