Re: [vmtk-users] Maximum inscribed sphere radius

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

Hi Nikhil,
 look at this tutorial:
http://www.vmtk.org/Tutorials/Centerlines/
for generating centerlines from a surface. Centerlines are the envelope of maximum inscribed spheres and carry the radius of the sphere at each point.
To extract the largest radius, just output the centerlines file with a .dat extension, which will essentially produce a CSV file with the radius as a last column. 
Or, in case you know how to use VTK, manipulate the vtkPolyData containing centerlines directly.
Best,

Luca
