FLofVLonsphereprojection

by Yilun Sun, SG-Lib Toolbox: SolidGeometry 5.6 - VL/Vertices/PC/Clouds
Introduced first in SolidGeometry 4.3, Creation date: 2018-10-17, Last change: 2025-09-14

returns a facet list that is based on alphashape triangulation of sphere projected vertices

Description

Point clouds that are recorded by a video camera create vertices that are equidistant if they are projected on to a internal surface of a sphere. Therefor this function projects first vertices to spherical, performs an alphashape triangulation, and returns the facets
