Detailed Description

template<typename T>
class pointsdisplay3D< T >

Draw and number the points.

On construction the geometry is written into a gobj container. The class keeps a reference to the quadric object made.

Example

  typedef point3<double> pt3;
  vector< pt3 > v;
  ... - fill v
  pointsdisplay3D<pt3> dp(xGraphics,v);
