Detailed Description

Abstract shape class, or simply "a shape".

Member Function Documentation

getPy()

virtual PyObject * AShape::getPy ( ) const

pure virtual

Return a Python representation of this object. Formats:

• ('circle', radius, x, y)
• ('triangle', v0, v1, v2) where v is (x,y,z)
• ('rect_iso', xmin, ymin, xmax, ymax)
• ('wide_segment', x0, y0, x1, y1, z, width)
• ('polygon', [v0, v1, v2, v3, ...]) where v is (x,y,z)

Implemented in CircleEx, IsoRectEx, PolygonEx, TriangleEx, and WideSegment_25.

transform()

virtual void AShape::transform ( const CGAL::Aff_transformation_2< Kernel > & )

pure virtual

Use transformType() if you are not sure whether the transformation preserves the shape type.

Implemented in CircleEx, IsoRectEx, PolygonEx, TriangleEx, and WideSegment_25.

transformPreservesType()

virtual bool AShape::transformPreservesType ( const CGAL::Aff_transformation_2< Kernel > & ) const

inlinevirtual

Check whether the transformation would change the shape's underlying type (sorry).

• Iso_rectangle_2 may become a Polygon_2 when (angle % 90) != 0
• Circle_2 may become an ellipse when scaled (this is not supported)

Reimplemented in CircleEx, and IsoRectEx.

transformType()

virtual AShape * AShape::transformType ( const CGAL::Aff_transformation_2< Kernel > & )

virtual

Transform this shape without restrictions.

Returns

@this or a new AShape.

Reimplemented in IsoRectEx.

vertexCount()

virtual uint AShape::vertexCount ( ) const

pure virtual

For rendering:

Implemented in CircleEx, IsoRectEx, PolygonEx, TriangleEx, and WideSegment_25.
