3D chess pattern

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:

Mesh pattern

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:

You can also generate colorful thread patterns using this script! Choose an angle value between 90 to 180 degree or between 270 to 360 degree, which will generate different patterns according to the angle input.

For example,

>> pattern(145)

Isn’t it really cool?
