question: returns the number of vertices in this polygon . the duplicated first/last vertex is not counted twice , so the result is equivalent to #getvertices . size . concode_field_sep List<VectorXYZ> vertexLoop concode_field_sep PolygonXZ getXZPolygon concode_elem_sep List<VectorXYZ> getVertexLoop concode_elem_sep SimplePolygonXZ getSimpleXZPolygon concode_elem_sep TriangleXYZ asTriangleXYZ concode_elem_sep List<VectorXYZ> getVertices concode_elem_sep PolygonXYZ reverse concode_elem_sep List<LineSegmentXYZ> getSegments
target: int function ( ) { return vertexLoop . size ( ) - 1 ; }
