# PhysicsShape.ShapeProxy

> A proxy of a shape in a generic form suited to representing all support shape types. You can provide between 1 and PhysicsConstants.MaxPolygonVertices and a radius. A CircleGeometry is a single point with a non-zero radius (zero radius is allowed however and defines a point). A CapsuleGeometry is two points with a non-zero radius. A PolygonGeometry box is the points with and an optional radius. A SegmentGeometry is two points with a zero radius. A ChainSegmentGeometry is two points with a zero radius. To create a proxy, simply provide the geometry to the constructor.
