APPENDIX B
Unit Circle Variation Bows

Unit Circle Variation Bows use polar coordinates and trigonometric functions.
The three-dimensional effect was created with pixel offset for a number of arbitrary iterations.

Unit Circle with Pseudocode

for (int i = 0; i ≤ 360000; i++)
{
	θ = i*0.001;
	for (k = 1; k ≤ 16; k++)
	{
		θ = 2.0 * θ;
		x = cos(θ);
		y = sin(θ);
	}
	PlotPoint(x, y, color);
}

Modified Unit Circle with Pseudocode

for (i = 0; i ≤ 180000; i++)
{
	x = 0.0;
	y = 0.0;
	θ = i*0.001;
	for (k = 1; k ≤ 2; k++)
	{
		θ = 2.0 * θ;
		xnew = cos(θ) + x;
		ynew = sin(θ) + y;
		x = xnew;
		y = ynew;
		PlotPoint(x, y, color);
	}
}
