insideCPS

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Analyzing function
Introduced first in SolidGeometry 4.5, Creation date: 2019-03-01, Last change: 2025-09-14

tests whether a point list is inside of a CPL polyshape or CPS

Description

SLOW FUNCTION FOR SINGLE POINTS - Use distanceVLtoVLEL to search on Contours
Replaces insideC, insidePLEL, insideinsidePLELdelaunay (which is TL's implementation of insideCPS)
In contrast to insideC, this function supports and uses the polyshape concept with several regions and holes: if there is no need for inside and on contour use "isinterior" directly
+1 means point is inside
-1 means point is outside
0 means point is on the contour

See Also: , insidePLELdelaunay

Example Illustration

missing image of insideCPS(CPL,PL);

Syntax

k=insideCPS(CPL,PL);

Input Parameter

CPL: Vertex list of the contour
PL: Point to check

Output Parameter

k: +1==inside, -1==outside, 0== on the contour

Examples


CPL=[PLsquare(6,4);nan nan;PLsquare(3,2)];
insideCPS(CPL,[-1 -1; -1 0; -1 1.5; -1 2.5; -1 -2])
insideCPS(CPL,[-1 -1; -1 0; -1 1.5; -1 2.5; -1 -2]+[-2 0])
