[vtkusers] vtkGlyph3D indexing problem !

[Sander Verhoeven]

Hello, I'm working on my thesis with the VTK ToolKit and i have some 
problems...

I want to put diffrent actors on some points of a mesh. I use vtkGlyph3D and 
set my sources in and setIndexModeToScalar();
// CODE
  glyph->SetSource(0, spheres->GetOutput());
  glyph->SetSource(1, spheres->GetOutput());
  glyph->SetSource(2, cubes->GetOutput());
  glyph->SetSource(3, spheres->GetOutput());
  glyph->SetSource(4, cubes->GetOutput());
  glyph->SetSource(5, cubes->GetOutput());
  glyph->SetSource(6, cones->GetOutput());
  glyph->SetIndexModeToScalar();
//

==> The problem is that only for the value 0 i see a sphere, the rest of the 
value's are all cones!!!  You can see it at the image : 
http://webs.hogent.be/~023174sv/BC2.jpg

You can see a actor of the lookuptable where you can see that each value has 
a diffrent colour, but alle values 1 --> 6 are CONES , and only number 6 
should be a cone....

Can anyone please help me ?

Also i have a other question, the size of the actors should fit to the mesh, 
that means that when the points are further from eachother the actors should 
be bigger when there are lot's of point laying next to eachother....., is it 
possible in any way to get the maximum distance between points of a 
unstructured grid?? Or any option to solve this problem

// HERE IS PART OF MY CODE:
 vtkConeSource * cones = vtkConeSource::New();
  cones->SetResolution(10);
  cones->SetRadius(radius);
  cones->SetHeight(radius*2);

 vtkSphereSource *spheres = vtkSphereSource::New();
   spheres->SetThetaResolution(10);
   spheres->SetPhiResolution(10);
   spheres->SetRadius(radius);

 vtkCubeSource * cubes = vtkCubeSource::New();
  cubes->SetXLength(radius);
  cubes->SetYLength(radius);
  cubes->SetZLength(radius);
