TR3mountingfaces

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - FS/Feature Surfaces
Introduced first in SolidGeometry 2.1, Creation date: 2015-02-01, Last change: 2025-09-14

finds connected facets with same normal vector

Description

Powerful but slow/recursive function to detect points that defined planar and spherical surfaces.
Auxiliary function developed originally for and used in SGTui

Example Illustration

Syntax

[FIL,nv,FnL,NnL,RL,CVL,TR3]=TR3mountingfaces(TR3,fi,[fe])

Input Parameter

`TR3`:		Surface triangulation of a solid
`fi`:		singe facet index
`fe`:		feature edge angle; default is 0

Output Parameter

`FIL`:		all facets connected to first facet with the same normal vector
`nv`:		normal vector of this facet
`FnL`:		all neigbor facets of FIL. WARNING: Always empty if fe>0
`NnL`:		normal vector angle difference to nv of FnL
`RL`:		Radial list created by CVLdimclassifier
`CVL`:		CLosed Vertex list used for CVLdimclassifier
`TR3`:		TR# is case that an SG was used as input parameter

Examples


SG=SGtransR(SGsample(25),rot(pi/6,0,pi/2)); TR3=triangulation(SG.FL,SG.VL);
[a,b,c,d,RL,CVL]=TR3mountingfaces(TR3,60,1);
SGfigure; h=SGplot(SG); setplotlight(h,'r',0.1); CVLplot(CVL); VLplot(RL(:,1:3),'k*',5);
