[vtkusers] Visualizing Deformation Field

[Markus Weigert]

Dear all,

I would like to visualize 3D deformation fields of deformable registrations
from ITK using colored and scaled arrows (ok, I managed to do this) together with a raycast
visualisation of the 3D source image.
The problem is now, that the arrows appear as dark shadows without color 
when the raycast is active.
Is there a way to exclude the arrows (glyphs) from raycasting projection in order to
see them as solid, colored objects in the scene when raycasting is active too???


Best regards,
Markus
