Facet List that contains entries of a vertex list

Description

This function can be used with vertex indices of the Solid given by VLFL
in nearest neighbor mode for any vertex list
Best is to call TR=triangulation(FL,VL); vi=nearestNeighbor(TR,vi); if vi ist a full vertex list

Example Illustration

missing image of FLofVLFLvi(VL,FL,vi)

Syntax

[FL,fi3,fi2,fi1,fi0]=FLofVLFLvi(VL,FL,vi)

Input Parameter

VL: Vertex list
FL: Facet List
vi: vertex index list OR logical vi or vertex list for triangulation.nearestNeighbor

Output Parameter

FL: FL(fi3,:); (GREEN)
fi3: all faces that have three points of VL(vi,:) - green
fi2: all faces that have 2 points of VL(vi,:) - yellow
fi1: all faces that have 1 points of VL(vi,:) - magenta
fi0: all faces that have 0 points of VL(vi,:) - red

Examples


SG=SGboxsphere; FLofVLFLvi(SG.VL,SG.FL,[1 2 3 4])
SG=SGboxsphere; FLofVLFLvi(SG.VL,SG.FL,[1 2 3]);
SG=SGboxsphere; FLofVLFLvi(SG.VL,SG.FL,[1 2 3]*1.00001);
