CPLsortinout
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - CPL/Closed Polygon Lists
Introduced first in SolidGeometry 3.6, Creation date: 2017-03-11, Last change: 2025-09-14
returns a inside outside sorted CPL (There is a changed behaviour
Description
For laser cutting, the insider first order is required. For automatic detection of corresponding vessels, outside first is important.
Corresponance matrix:
(i,j)==+1 i is inside j, -1== i is outside j, NaN==crossing

Syntax
[cind,CC,NCPL,pi]=CPLsortinout([CPL,in1st])
Input Parameter
CPL: | | Original CPL |
in1st: | | true==inside first; false=outside first; default is true |
Output Parameter
cind: | | level index related to separatedNaN (CPL) |
CC: | | Corresponance matrix |
