SGconvexHullsliced
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - SG/Solids
Introduced first in SolidGeometry 5.4, Creation date: 2024-08-21, Last change: 2025-09-15
creates a high resultion fittin convex contour in xy and a sliced on in z
Description
Slow function that requires appropriate parameters!
This is the 3rd try (and 1st working version) to create such a function
SGofCVLslices introduced 2017-MAI-26
SGconvexsolidofSG introduced in 2020-AUG-15
SGwatertightofSG introduced in 2020-AUG-28 (is not a convec shape based on voxels)
SGconvexHullsliced tries to finish 2024-AUG-21
In fact the function CPLconvexhulloutline (2021) seems to make it possible

Syntax
[SGN,FLW,FLA,FLB]=SGconvexHullsliced(SG,[ra,Dcl,"debug"])
Input Parameter
SG: | | Solid Geometry |
ra: | | z resolution and auxiliary point distance; default is [s/50 1] |
Dcl: | | Diameter of small holes in the contour to be closed; default is 3 for M3; |
"debug": | | if used the creation process is shown |
Output Parameter
SGN: | | Convex solid [FL=[FLA;FLB;FLW] |
FLW: | | facet list of wall |
FLA: | | facet list of floor |
FLB: | | facet list of cover |
