VLFLfusedoubledvertices
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - VLFL/Surfaces
Introduced first in SolidGeometry 5.5, Creation date: 2025-08-12, Last change: 2025-09-15
fuses vertices with similar positions, shortens the VL, but the number of facets remains unchanged.
Description
This function probably already exists in several places, but as of 2024a/b, the behavior of delaunayTriangulation has changed and bugs occur in SGremsurfedgepoints, which makes it necessary to examine the individual steps in detail.

Syntax
[NVL,NFL]=VLFLfusedoubledvertices(VL,FL,[thr])
Input Parameter
VL: | | Vertex list |
FL: | | Facet list |
thr: | | Threshold für round(VL,thr); default is 1e-17 DO NOT USE DIGITS |
Output Parameter
NVL: | | New vertex list |
NFL: | | New facet list |
Examples
A=SGlinkage(5,30,5); model=pdemodelofSG(A,1); SGofpdemodel(model); B=ans
VLFLfusedoubledvertices(B.VL,B.FL,0.1); % even with 0.1mm no change
VLFLfusedoubledvertices(B.VL,B.FL,1); % with 1mm changes and non manifold problems
