Hmmm.. I'd be flippin' burgers if it weren't for you Marc =-)

anyway.. still no luck. I did realize I have no idea what I'm doing so I
went and read some sources,
and I've made my subclass as similar as vtkFollower (which is a working
subclass of vtkActor), but I'm
getting the same effect.

The object is there but is invisible.. it does not get rendered. I've
searched vtkuser-archives but have
found nothing new.

VTK is really very, very nice, but a bit steep I must say.
I really appreciate all the help I'm getting here!


/***  vtkPigment.h ***/

#ifndef __vtkPigment_h
#define __vtkPigment_h
#include "vtkActor.h"

class VTK_RENDERING_EXPORT vtkPigment : public vtkActor
{
public:
   vtkTypeRevisionMacro(vtkPigment,vtkActor);
   static vtkPigment *New();
protected:
   vtkPigment(){}
   ~vtkPigment(){}
};

#endif

/*** vtkPigment.cpp ***/

#include "vtkPigment.h"
#include "vtkObjectFactory.h"

vtkCxxRevisionMacro(vtkPigment, "$Revision: 1.45 $");
vtkStandardNewMacro(vtkPigment);

Cheers!!
