[vtkusers] memory friedly glyphs

[tobes]

Hi,

im new to vtk ...

I tried to visualize a volume (for volume carving). 
For that i use vtkStructuredGrid, fill it wiht vtkPoints
and use a vtkGlyph3d wit a vtkCubeSource.

The problem is the volume may be 64x64x64 (or even larger!)
and glyph3d makes a copy of each cube, so im running into 
memory proplems.

Is there a way to display a box at each volume point without copying?
