# != null

The shape to describe.

The shape type.

The georeference of the shape vertices.

Is this a cubemap shape?

Cubemap shapes have a geographic coordinate system and six separate sub-shapes, one for each cubemap face (see Face)).

The number of shape vertices.

When the vertex count is zero, the shape is defined implicitly. If the vertex count is greater than zero, the shape is explicitly defined by its vertices.

The number of shape edges.

Defines how the vertex winding of polygon contours is interpreted (outer rings vs. holes):
> +/- 1 for polygons, 0 for non-polygon shapes.

A polygon contour is classified as an outer ring or a hole according to the sign of its signed area:

outer := sign(Area(contour)) == Parity
hole  := sign(Area(contour)) != Parity

The default value is -1 (i.e. clockwise orientation in a standard Cartesian coordinate system).

The number of shape triangles.
