subTriSplit

Below is a demonstration of the features of the subTriSplit function

Contents

Syntax

[Fs,Vs]=subTriSplit(F,V,n);

Description

The subTriSplit function enables refinement of triangulated data by linearly splitting each triangle into 4 new triangles with each iteration.

Examples

clear; close all; clc;

Plot Settings

fontSize=15;
faceAlpha=1;
edgeColor=0.2*ones(1,3);
edgeWidth=1.5;
markerSize=35;
markerSize2=20;

Refining a triangulation through linear splitting

Example data, an icosahedron

[V,F]=platonic_solid(4);

Refine using subTriSplit

n=3; % Number of split iterations
[Fn,Vn]=subTriSplit(F,V,n); %Refine by linear splitting

cFigure; hold on;
hp1=gpatch(F,V,'none','r',0,4);
% patchNormPlot(F,V,[],[],'r');
hp2=gpatch(Fn,Vn,'w','b',1,1);
% patchNormPlot(Fn,Vn,[],[],'b');
legend([hp1 hp2],{'Original',['Split ',num2str(n),' times' ]});
