I think what you are doing is fine. Those meshes were made over 25 years
ago, so the details you seek are probably lost

Hello,
I am working on generating a vertex mapping file that identifies
corresponding vertices across different levels of an icosahedral mesh.
Specifically, for ico6, I want to determine which vertices contribute
to each vertex in ico5 when downsampling is performed.
Currently, I approximate this mapping using Euclidean distance: for
each vertex in ico5, I find the /n/ closest vertices in ico6 based on
their (x, y, z) coordinates, then average across these. However, I’m
wondering if there is a more formal or standard approach to defining
these vertex correspondences—perhaps one based on the hierarchical
structure of icosahedral refinement.
Would you have any suggestions for a more principled method to
determine vertex equivalence across levels?
Thanks,
Sam
