TPointSet3D Class Reference

TPolyMarker3D using TPointSet3DGL for direct OpenGL rendering.

Supports only elementary marker types:

• 4, 20, 24 : round points, size in pixels;
• 2, 3, 5 : crosses, size in scene units;
• 28 : as above, line width 2 pixels;
• all other : square points, size in pixels.

Marker-size (from TAttMarker) is multiplied by 5!

An identification of type TObject* can be assigned to each point via SetPointId() method. Set the fOwnIds flag if the ids are owned by the point-set and should be deleted when pointset is cleared or destructed.

Copy-constructor and assignment operator COPIES the ids if the are not owned and CLONES them if they are owned.

The ids are not streamed.

void TPointSet3D::PointSelected ( Int_t  n )

virtual

This virtual method is called from TPointSet3DGL when a point is selected.

At this point it just prints out n and id of the point (if it exists). To make something useful out of this do:

1. subclass and re-implement this method;
2. extend this class to include TExec or some other kind of callback.
