Face
Represents a section bounded by a specific amount of half-edges. The current implmentation assumes that a face always consist of three edges.
Constructor
Face()
Creates a new instance of Face.
Properties
.normal : Vector3
The normal vector of the face. Default is a Vector3 at (0, 0, 0).
.midpoint : Vector3
The midpoint or centroid of the face. Default is a Vector3 at (0, 0, 0).
.area : Float
The area of the face. Default is 0.
.constant : Float
Signed distance from face to the origin. Default is 0.
.outside : VertexNode
Reference to a vertex in a vertex list this face can see. Default is null.
.mark : Integer
Marks if a face is visible or deleted. Default is 'Visible'.
.edge : HalfEdge
Reference to the base edge of a face. To retrieve all edges, you can use the 'next' reference of the current edge. Default is null.
Methods
.create ( a : VertexNode, b : VertexNode, c : VertexNode ) : Face
a - First vertex of the face.
b - Second vertex of the face.
c - Third vertex of the face.
Creates a face.
.getEdge ( i : Integer ) : HalfEdge
i - The index of the edge.
Returns an edge by the given index.
.compute () : Face
Computes all properties of the face.
.distanceToPoint ( point : Vector3 ) : Float
point - Any point in 3D space.
Returns the signed distance from a given point to the plane representation of this face.
