The centre of the bounding rectangle. consider also using cenDefault.

Currently throws, not sure if that is the correct behaviour. Creates a bounding rectangle for a collection of 2d points

The width of the BoundingRect of this object.

This canEqual override allow the comparison of Shapes.

If the geometric element has a defined centre then the cenDefault uses that, else it defaults to the centre of the bounding rectangle.

The centre point of this Polygon. The default centre for Polygons is the centre of the bounding rectangle.

Creates a PolygonCompound graphic that is active with a simple 1 colour fill and has a draw graphic for the Polygon. The default values for the draw area line width of 2 and a colour of Black.

foreachs over the sides or edges of the Polygon These are of type LineSeg.

foreachs over the sides or edges of the Polygon These are of type LineSeg.

Insert vertex.

Insert vertices before the specified insertion vertex.

Map this collection of data elements to PolygonLike class of type BB.

Determines if the parameter point lies inside this Polygon.

Uniform scaling 2D geometric transformation. The scale name was chosen for this operation as it is normally the desired operation and preserves Circles and Squares. Use the xyScale method for differential scaling.

Polygon side 1 from the last vertex to Vertex 1.

The X component of the centre or half way point of side 1 of this polygon. Side 1 starts at the vLast vertex and ends at the v1 vertex. This can be thought of as vertex 0.5.

The Y component of the centre or half way point of side 1 of this polygon. Side 1 starts at the vLast vertex and ends at the v1 vertex. This can be thought of as vertex 0.5.

Polygon side 2 from vertex 1 to vertex 2.

Polygon side 3 from v2 to v3.

The X component of the centre or half way point of side 3 of this polygon. Side 3 starts at the v2 vertex and ends at the v3 vertex. This can be thought of as vertex 2.5.

The Y component of the centre or half way point of side 3 of this polygon. Side 3 starts at the v2 vertex and ends at the v3 vertex. This can be thought of as vertex 2.5.

maps with a integer counter over the sides or edges of the Polygon These are of type LineSeg.

Translate 2D geometric transformation on a Triangle returns a Triangle. The return type is narrowed in sub classes.

The last vertex.

flatMap to an immutable Arr.

This method should be overridden in final classes.
