Hi,

I would like to know if it is possible to adapt my geometry objects to the Boost.Geometry concepts without major changes in the old code. My classes look like that (simplified):

class CgPoint
{
public:
       // Coordinates
       double x;
       double y;
};

class Polygon
{
public:
       CVectorBlock*        pHoles;
protected:
       int          npkt;                                          // number of points
       CgPoint*     punkt;                                         // point array
};

class CVectorBlock
{
protected:
       std::vector< Polygon *>    vektor;                           // all the elements in the block
};

The point class CgPoint is straight forward but I begin having problems when I try to define the ring concept cause Polygon behaves like both, a ring and a polygon, and I don't have encapsulated in a class the concept of exterior ring. Any idea?

Thanks,
XaVS
