Methods

computeCentroid() → Polygon

Computes the centroid for this polygon.

contains(Vector3 point, [double epsilon = 1e-3]) → bool

Returns true if the polygon contains the given point.

convex([bool ccw = true]) → bool

Returns true if the polygon is convex.

coplanar([double epsilon = 1e-3]) → bool

Returns true if the polygon is coplanar.

distanceToPoint(Vector3 point) → double

Computes the signed distance from the given 3D vector to this polygon. The method uses the polygon's plane abstraction in order to compute this value.

fromContour(List<Vector3> points) → Polygon

Creates the polygon based on the given array of points in 3D space. The method assumes the contour (the sequence of points) is defined in CCW order.

getContour(List<Vector3> result) → List<Vector3>

Determines the contour (sequence of points) of this polygon and stores the result in the given array.

getEdge(int i) → HalfEdge?

leftOn(Vector3 a, Vector3 b, Vector3 c) → bool

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
