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.

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