[vmtk-users] 2 questions on segmentation

[Vikram M. <vv...@gm...>]

Dear users,

I have a couple of questions and I was hoping to get some advice on this.

1) Is there a way of aligning one of the ends of the reconstructed geometry
with any of the axes?
    I use the geometries as a model for CFD simulations and some other
processing methods in matlab. I need the vessel to be aligned with the x
axis (for example) with the center of the inlet at the origin so that my
boundary conditions are prescribed accurately.. I usually do it in other
meshing softwares and I was wondering if this could be done in VMTK prior
to exporting it as an STL file.


2) Sometimes during the segmentation process, I end up with reconstructions
with artificial bumps on them. Is there a way to INDIVIDUALLY smooth these
bumps out ? Are there ways to avoid this ?  I do not want to over smooth
the entire vessel and hence a way of smoothing just the rough/bumpy bits
would be great !    Any suggestions would help !

Any help is greatly appreciated !

Many thanks in advance
Vikram.
