I am currently trying to find the gaussian and mean curvatures of a model I am working with. The initial mesh was created from a photoscan using Agisoft Metashape.
I tried converting the mesh into a surface using ‘MeshtoNURB’, but this creates a polysurface that does not work with Rhino’s built in ‘CurvatureAnalysis’ function.
I then tried using the ‘MeshCurvature’ function within grasshopper, but it often returned a constant curvature, or only a handful out of 600,000+ faces differing slightly. I also tried this after applying ‘smooth’ in hopes of making the mesh continuous, but it gave the same result.
I would like to avoid creating an entirely new surface based on the mesh if possible, but will do so if it is the only way.
Any help is appreciated!
