Do you think it is difficult to make 3 dimensional patterns like this one? then you are wrong. Its absolutely not!

The basic line pattern of this chess pattern is as shown below:

Such line patterns can be easily generated using this simple Matlab script:

``````function pattern(angle)
lower = 2;
upper = 12;
stepvalue = 0.2;
lastindex = (upper-lower) * (1/stepvalue) + 1;
mid = ceil(lastindex/2);
x = [lower:stepvalue:upper];
line1 = tand(angle)*x;
line2 = tand(180-angle)*x + line1(lastindex)+line1(1);
plot(x,line1,x,line2);
for i = 1:(mid-1)
hold all
plot([x(i),x(mid+i)],[line1(i),line2(mid+i)]);
hold all
plot([x(i),x(mid-i)],[line1(i),line2(mid-i)]);
hold all
plot([x((mid*2)-i),x(mid+i)],[line1((mid*2)-i),line2(mid+i)]);
hold all
plot([x((mid*2)-i),x(mid-i)],[line1((mid*2)-i),line2(mid-i)]);
end

daspect([1,1,1]);
set(gca,'XTick',[0:1:(upper+2)]);
set(gca,'YTick',[0:1:line1(lastindex)+1]);
set(gca,'XLim',[0 (upper+2)]);
set(gca,'YLim',[0 line1(lastindex)+1]);
set(findobj('Type','line'),'Color','black');
end
``````

Run this script as:

``````>> pattern( angle_value )
``````

For example,

``````>> pattern(45)
``````

This will generate the pattern shown below:

``````>> pattern(145)
