VLFLremsurfedgepoints
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Surfaces
Introduced first in SolidGeometry 4.2, Creation date: 2018-03-06, Last change: 2025-09-14
returns a surface model without edge points and surface points that are inside of a surface
Description
Calls function as SGremsurfedgepoints. This function is useful if a tetrahedron model (pde mesh) is converted into a surface model, or a solid is bent somehow. Afterwards there a surfaces that consist of many vertices that are in the same plane. This function analyses the surface and retesselate all surface based only on the boundary vertices.

Syntax
[VLN,FLN,FLNorg,FSi]=VLFLremsurfedgepoints(VL,FL,[alpha,minf])
Input Parameter
VL: | | Vertex list of surface model |
FL: | | Facet list of surface model |
alpha: | | alpha angle for feature surface; default is 0.01 |
minf: | | minimum facets per face; default is 4 |
Output Parameter
VLN: | | New vertex list surface model with reduced vertices |
FLN: | | New facet list surface model with reduced vertices |
FLNorg: | | Reduced Facet list based on the original vertex list |
FSi: | | Feature surface index list |
