# polyTube

Below is a basic demonstration of the features of the `polyTube` function.

## Contents

clear; close all; clc; % PLOT SETTINGS fig_color='w'; fig_colordef='white'; markerSize=15; lineWidth=2; fontSize=10;

Creating example curve

ns=150; t=linspace(0,-pi,ns); r=10+7.*sin(8*t); [x,y] = pol2cart(t,r); z=7*cos(10.*t); V=[x(:) y(:) z(:)];

## BUIDLING THE TUBE

```
optStruct.r=0.25;
optStruct.nr=5;
optStruct.patchType='tri';
[Fs,Vs,Cs,Cs_rgb,Cs_d]=polyTube(V,optStruct);
```
