VLFLinsertFacetPoints
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Surfaces
Introduced first in SolidGeometry 2.1, Creation date: 2015-01-12, Last change: 2025-09-14
This fnct retesselates all surfaces of a solid by inserting points into existing facets
Description
This function is an elementary part of SGbool1-SGbool3 and was isolated for SGbool4 in 2017-08-02
It is not enough just to add the points to a triangle but also it is necessary to add edges inside of the facet for each cutting edge! Otherwise it is not possible to reconnect the two separated handled Solids!
The final result are THREE retesselate facet list: NFL and SFL and UFL
The orientation of the faces of SFL are changed.

Syntax
[XVL,XFIL,NFL,SFL,UFL]=VLFLinsertFacetPoints(VLA,FLA,NPL)
Input Parameter
VLA: | | Solid A |
FLA: | | Solid B |
NPL: | | New Point List created by SGintersectFacetPoints |
Output Parameter
XVL: | | Original point list plus additional points |
XFIL: | | Facet index list of original facets that were changed |
NFL: | | Facets that belong completely to crossing points (red) |
SFL: | | Facets that connect untouched points and crossing points (yellow) |
UFL: | | Facets that are not touched (green) |
Examples
A=SGbox([30,20,10]); B=SGtransP(A,[1 2 3]); SGintersectFacetPoints(A,B); NPL=ans
A=SGbox([30,20,10]); B=SGofCPLz([PLcircle(4);NaN NaN;PLcircle(2)],10);SGintersectFacetPoints(A,B); NPL=ans
VLFLinsertFacetPoints(A.VL,A.FL,NPL)
VLFLinsertFacetPoints(B.VL,B.FL,NPL(:,[2 1 3:end]))
