Luca, the first pipe worked perfectly for what I was doing. Your other points
will definitely be useful in the future, though. Thanks again.
Ben

Subject: Re: [vmtk-users] Overlaying
Dear Ben,
if by overlaying you only intend to show them together you can use the
vmtkrenderer script ahead of the pipe - this will cause all renderings to
happen in the same window:
vmtkrenderer --pipe vmtksurfaceviewer -ifile surface1.vtp -opacity 0.5 -color
1.0 0.8 0.8 --pipe vmtksurfaceviewer -ifile centerline1.vtp --pipe
vmtksurfaceviewer -ifile surface2.vtp -opacity 0.5 -color 0.8 1.0 0.8 --pipe ...
However, if your models are not colocated in space and you also want to bring
them close together, you have two possibilities:
1. Use the vmtkicpregistration script to align one surface to the other, and
then optionally use vmtksurfacetransform to use the same transform matrix to
transform, say, the centerlines using the same transformation matrix.
2. Use the vmtksurfacetransforminteractive script to manually transform one
surface to the next. Same as above, you can then use the same matrix to
transform other data you may want to bring along.
Let me know if you need more details on these steps or if the former pipe was
enough for your needs.
Best regards
Luca

Hi,
I've had multiple occasions where I've wanted to overlay a vessel model or a
centerline over another model or centerline. Is there any easy way to do this
from PypePad, or do I need to go more complicated and do it using VTK commands?
Thanks,
Ben Berkowitz
