Re: [vmtk-users] Coordinates of a centerline

[Richard Downe]

Personally, I write my stl files myself, because I build my surfaces in another program. Attached is a perl script I've used for converting .off files to .stl -- should be trivial to adapt it to python/iterate over a vtkPolyData instead of .off input.

Hi Arjan,

Thanks alot for your response. I seem to have got all the data I needed.


On a separate note,



Thanks alot !

Vikram.

Does anyone know how to save your surface file as an ASCII STL and not a binary one. On Tue, Oct 16, 2012 at 9:47 PM, Arjan Geers <ajge...@gmail.com <mailto:ajge...@gmail.com>> wrote:

    Hi Vikram,

    You could try this:

    vmtksurfacereader -ifile /home/vm308/catheter.vtp --pipe
    vmtkcenterlines -seedselector openprofiles -ofile catheter_cl.dat

    It should give you the coordinates of the centerline points in a
    human-readable format.

    Good luck with it,

    Arjan

        Dear VMTK users,

        I have a surface reconstruction of a catheter within a
        coronary artery and have also generated the centerlines for it.
        However, for further processing, I need the coordinates of the
        catheter centerline and was wondering if you all had any idea
        to do this ?
        I tried using vmtkcenterlinegeometry but I might be doing
        something wrong,

        vmtksurfacereader -ifile /home/vm308/catheter.vtp --pipe


        Ideally I would like a .txt file (basically a point cloud) -
        is this achievable ?

        Please advise.

        Looking forward to your replies

        Thanks in advance,
        Vikram.
