Polygon::PlaneCCW
Syntax
Plane Polygon::PlaneCCW() const; [41 lines of code]Computes the plane this polygon is contained in.
Note
Only call this function if this Polygon is planar.
Return Value
The plane equation of this polygon. This normal vector of the plane points to the direction from which observed the vertices of this polygon wind in counter-clockwise order.
Syntax
Plane Polygon::PlaneCW() const; [6 lines of code]Computes the plane this polygon is contained in, with a normal vector that points in the clockwise direction.
Note
Only call this function if this Polygon is planar. The functions PlaneCCW() and PlaneCW() return the same plane, except the normals of the planes point in opposite directions.
