# quadBox

Below is a demonstration of the features of the `quadBox` function

## Contents

```
clear; close all; clc;
```

## Syntax

`[F,V,faceBoundaryMarker]=quadBox(boxDim,boxEl);`

## Description

This function generates the patch data for a quadrilateral mesh rectangular box. The patch data consists of the faces (F), the vertices (V), and face color/label data (faceBoundaryMarker). The input parameters boxDim (1x3 vector) and BoxEl (1x3 vector) define the dimensions of the box and the number of elements to use in all 3 directions.

## Examples

Plot settings

fontSize=15; faceAlpha1=0.5;

## Creating a quadrilateral mesh of a box

Specifying dimensions and number of elements for each direction

boxDim=[4 5 6]; %Size of the box in each direction boxEl=[3 4 5]; %Number of elements per direction

Using `quadBox` to build the patch model

[F,V,faceBoundaryMarker]=quadBox(boxDim,boxEl);

Plotting model

cFigure; hold on; title('Box quadrilateral faces and normals','FontSize',fontSize); gpatch(F,V,faceBoundaryMarker,'k',faceAlpha1); % patchNormPlot(F,V); colormap(gjet(6)); icolorbar; axisGeom(gca,fontSize); camlight headlight; drawnow;
