Detailed Description

template<class Geom, class Trafo>
class GrAL::transformed_geom< Geom, Trafo >

Grid geometry transformed by a mapping.

The only function is currently transformation of vertices -- every other geometric primitive depends on the nature of the transformation, i.e linear or non-linear.

Template parameters:

• Geom: Model of VertexGridGeometry
• Trafo: Model of Unary Function
  (Geom::coord_type -> Trafo::result_type)

Todo:

Extend approach to yield transformed (i.e., curved) segments, polygons etc.
