Hi, fantastic work here. Slicer is great.
I have advanced on my own but could do with a kind and helping hand for the last step.
Very quickly :
I have two models. The fist one has been created from a segmented volume and “painted” by probevolumefrommodel. The other model is a polydata model imported from an electro-anatomical CARTO® map. I need to compare the values associated with those two models on a “point by point” basis, to draw some correlation.
What I did :
I created 5000 fiducials points on the first model,
I registered the model to the other one by means of non rigid transformation, and applied this transformation to the fiducials.
I projected the 5000 transformed points to the second model using nearest distance projection. I now have 2 sets of related fiducials, one on each model surface, that i would like to compare in term of the underlying scalar data.
How should I proceed in order to sample each model at each and every fiducial point ?
Alternativly I could use another approach if more practical.
Regards, and again many thanks for this gem of a software.
