QLiss3D  Lissajous Figures


This is the graph of a sine function. The x value is increasing continiously
while the y value is the result of sin(x).



In this picture you can see a very simple Lissajous figure. Y and xfrequency are the same.
Both x and yvalues of the painted pixels are results of sin(i), where i is
an increasing counting variable.



Here the xfrequency is twice as high as the yfrequency and the resulting Lissajous figure
consists of points with the coordinates (sin(2i)sin(i)). 
QLiss3D adds a third dimension with a third frequency to these Lissajous figures.
A good introduction to Lissajous curves can be found in Wikipedia.
