that is nice.

For BC++ just use int and not size_t. It is not aching because we use
ONLY specialized classes, like point<double,3> which could be
instaciated, or?

Congratulations.
Okay, where could we discuss that topic? Would be nice to have a place.
Another code snippet for you without any comment ;-) :
#ifndef _ENTITIES_HPP_
#define _ENTITIES_HPP_
#include <boost/numeric/ublas/vector.hpp>
#include <boost/numeric/ublas/matrix.hpp>
class GeometricEntity {};
template <typename T,int s> class GeometricVectorEntity :
public GeometricEntity, public
boost::numeric::ublas::bounded_vector<T,s> {};
template <typename T,int r,int c> class GeometricMatrixEntity :
public GeometricEntity, public
boost::numeric::ublas::bounded_matrix<T,r,c> {};
// int used for second parameter because borland gets confused with
size_t
template <typename T,int> class point;
template <typename T,int> class line;
template <typename T,int> class plane;
template <typename T,int> class circle;
// Specialization of the basic elements
template <typename T> class point<T,2> : public
GeometricVectorEntity<T,3> {};
template <typename T> class line<T,2> : public
GeometricVectorEntity<T,3> {};
template <typename T> class plane<T,2> : public
GeometricVectorEntity<T,3> {};
template <typename T> class circle<T,2> : public
GeometricMatrixEntity<T,3,3> {};
template <typename T> class point<T,3> : public
GeometricVectorEntity<T,4> {};
template <typename T> class line<T,3> : public
GeometricVectorEntity<T,6> {};
template <typename T> class plane<T,3> : public
GeometricVectorEntity<T,4> {};
template <typename T> class circle<T,3> : public
GeometricMatrixEntity<T,3,3> {};
#endif
Greetings,
Patrick
