# 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' ]}); axisGeom; camlight headlight; drawnow;
