[Insight-users] polydata and bsplinetransform

[Daniel Schwarz]

 Dear all,

 I would like to ask you for a help. I have a vtk ascii file with 
 polydata and I have a tfm file with bspline transform generated from 
 Slicer. With the help of ITK, I would like to make a small program which 
 would change positions of the points in the polydata file according to 
 the bspline transform. Yes, it can be done in Slicer, but only for small 
 polydata files, whereas for huge amounts of polydata Slicer freezes. I 
 was looking for ITK examples which work with itk::linecell as well as 
 itk:bsplinedeformabletransform, but have not found any. I made a script 
 in Matlab with the use of TriScatteredInterp(), but this seems to  be 
 computing indefinitely...

 Many thanks for any help - a snippet of code or pseudocode would help 
 me a lot as I am new to Slicer and so far able to modify examples 
 only...

 Daniel
