clear; close all; clc;

Syntax

M=checkerBoard3D(siz);

Description

This function creates a checkboard image of the size siz whereby elements are either black (0) or white (1). The first element is white.

Examples

Plot settings

fontSize=15;

Example creating a 2D checkerboard image

siz=[4 6]; %Image size
M=checkerBoard3D(siz); %Create checkerboard image

Plotting results

cFigure;
title('A 2D checkerboard pattern','FontSize',fontSize);
xlabel('X','FontSize',fontSize);ylabel('Y','FontSize',fontSize); zlabel('Z','FontSize',fontSize);
hold on;
imagesc(M);

colormap gray;
axis equal; view(2); axis tight;
set(gca,'FontSize',fontSize);
drawnow;

Example creating a 3D checkerboard image

siz=[6 6 3]; %Image size
M=checkerBoard3D(siz); %Create checkerboard image

Plotting results

[Fv,Vv,Cv]=im2patch(M,1:numel(M),'vb'); %Create patch data for plotting

cFigure; hold on;
title('A 3D checkerboard pattern','FontSize',fontSize);
gpatch(Fv,Vv,Cv);

camlight('headlight');
colormap gray;
axisGeom;
set(gca,'FontSize',fontSize);
drawnow;

Example, changing checkerboard block size

siz=[50 50]; %Image size
blockSize=10; %Block size in pixel units
M=checkerBoard3D(siz,blockSize); %Create checkerboard image

Plotting results

[Fv,Vv,Cv]=im2patch(M,1:numel(M),'vb'); %Create patch data for plotting

cFigure; hold on;
title('A 2D checkerboard pattern','FontSize',fontSize);
gpatch(Fv,Vv,Cv,'r',1,1);

colormap gray;
axisGeom; view(2);
set(gca,'FontSize',fontSize);
drawnow;

siz=[12 12 6]; %Image size
blockSize=3; %Block size in pixel units
M=checkerBoard3D(siz,blockSize); %Create checkerboard image

Plotting results

[Fv,Vv,Cv]=im2patch(M,1:numel(M),'vb'); %Create patch data for plotting

cFigure; hold on;
title('A 3D checkerboard pattern','FontSize',fontSize);
gpatch(Fv,Vv,Cv,'r',1,1);

camlight('headlight');
colormap gray;
axisGeom;
set(gca,'FontSize',fontSize);
drawnow;
