Re: [vmtk-users] Computing centerline geometry

[Luca A. <luc...@or...>]

Hi Qiang,
 the script works, I'm attaching the result and a Paraview screenshot where the Glyph filter has been applied to the Frenet normals.

Note that I specified a higher number of iterations and factor than the default, to diminish the effect of noise on the finite difference approximation of derivatives.

vmtkcenterlinegeometry -ifile wf2011.8.31-20080918-L-3-1-3.18_centerlines.vtp -smoothing 1 -ofile foobar.vtp -iterations 1000 -factor 0.5

But  I am dealing with split centerlines, the script "vmtkcenterlines -ifile foo.vtp -seedselector openprofiles --pipe vmtkbranchextractor --pipe vmtkbranchgeometry -ofile foo_clcg.vtp" is OK for the same vessel (as an attachment).
