coplanar method

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

Returns true if the polygon is coplanar.

Implementation

bool coplanar([double epsilon = 1e-3 ]) {
	final plane = this.plane;
	HalfEdge? edge = this.edge;

	do{
		final distance = plane.distanceToPoint( edge!.vertex );

		if ( distance.abs() > epsilon ) {
			return false;
		}

		edge = edge.next;
	} while ( edge != this.edge );

	return true;
}
