CG_Polygon

Description

A drawable polygon.

Constructor

CG_Polygon((optional) [CG_Vertex] vertices)

Attributes

`[CG_Vertex] VertexList`	A list of edges contained in this polygon.
`[CG_Edge] EdgeList`	A list of edges contained in this polygon.

Functions

`CG_Vertex v(Number i)`	Returns vertex with index `i % VertexList.length`.
`CG_Edge e(Number i)`	Returns edge with index `i % EdgeList.length`.
`null newVertex(CG_Vertex v)`	Adds vertex `v` to `VertexList` and rebuilds the edge list.
`CG_Edge newEdge(CG_Vertex u, CG_Vertex v)`	Adds a new edge with endpoints `u` and `v`.
`null buildHull()`	Constructs the edge list from vertices in `VertexList`
`[CG_Vertex] fetchVertices()`	Returns the list of vertices in `EdgeList`.
`Boolean orient(Number i, Number j, CG_Vertex w)`	Returns `w.ccw(this.v(i), this.v(j))`.
