Dear all, Happy new year to everyone! I'm looking for some advice on how to best/efficiently calculate the area of an articular surface using R.
I have 3D landmark data (collected in Amira) that I want to use to calculate the area of different articular surfaces. I want my surfaces were not aligned to orthogonal planes when I collected the data What I've tried so far is to re-align the landmarks of the surfaces I'm interested to one of the orthogonal planes (using 3 points) and then removing one of the dimensions so that I have a 2D polygon that I can use Gauss's area formula. However, because I am only using 3 points to determine the 'new' orthogonal plane, I have doubts that this is the best way to do this since not all of other landmarks fall on this plane. Does anyone have any suggestions on how to do this better or is there an R-package that does this already?
