findfacetsinVLFL

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Geometric Queries
Introduced first in SolidGeometry 4.7, Creation date: 2019-07-13, Last change: 2025-09-14

creates a correlation index list of the facets in FLA and FLB

Description

Change in SG-Lib 4.9: Supports order and direction
slow(up to 6 recursive calls)

See Also: ismemberFL , maprows , SGcolorcopy

Example Illustration

missing image of findfacetsinVLFL(VLA,FLA,VLB,FLB,order,flips)

Syntax

cc=findfacetsinVLFL(VLA,FLA,VLB,FLB,[order,flips])

Input Parameter

`VLA`:		Vertex list Solid A
`FLA`:		Facet list Solid A
`VLB`:		Vertex list Solid B
`FLB`:		Facet list Solid B
`order`:		if true the vertex order is ignored; default is false
`flips`:		if true the facet direction is ignored; default is false

Output Parameter

cc: facet correlation index list [ai bi]

Examples


SGofCPLz(PLstar(10),5); A=ans;
SGofCPLz(PLcircle(10),5); B=ans; SGtransrelSG(B,A,'ontop',5,'transx',3); B=ans
SGTset(A,'M',[0 0 1]); A=ans; 
SGTset(B,'M',[0 0 -1]); B=ans;
SGconnect2FS(A,B,FSofSGfacet(A,31),TofFS(B,[0 0 -1])); C=ans
findfacetsinVLFL(A.VL,A.FL,C.VL,C.FL)

findfacetsinVLFL(A.VL,A.FL,C.VL,C.FL(:,[2 3 1]),false)
findfacetsinVLFL(A.VL,A.FL,C.VL,C.FL(:,[2 3 1]),true)    % finds even in other order

findfacetsinVLFL(A.VL,A.FL,C.VL,C.FL(:,[1 3 2]),'',false)
findfacetsinVLFL(A.VL,A.FL,C.VL,C.FL(:,[1 3 2]),'',true)   % finds even in flip surface normal
