VLFLofVLELdelaunay3D
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Surfaces
Introduced first in SolidGeometry 4.1, Creation date: 2017-08-28, Last change: 2025-09-14
returns the top and below tesselation for ONE closed vertex list which cuts a convex solid into two parts
Description
In contrast to VLFLofCVLdelaunay3D, this function VLFLofVLELdelaunay3D is not limited to the vertex points that are used in CVL. Based on the VL a convex solid is created and separted into two halfs/parts by the given EL. This works currently in 3D only for one closed contour.
