PolygonShape

Shape
public sealed class PolygonShape : Shape
Represents an n-gon for ray intersections. Shape may have concave portions, although self-intersections are ill-advised.

Constructors

Create a new n-gon.
Parameters:
x (IEnumerable<double>)
y (IEnumerable<double>)

Properties

Bounds

#
public override Box Bounds { get; }
Gets the bounding box for this shape.
Overrides: Shape.Bounds

Count

#
public int Count { get; }
Gets the number of corners.

IsEmpty

#

Parameters:
box (Box)Box.
Returns: Overlap topology.
Overrides: Shape.Overlap
