Well, it's a time consuming process.
Here it is in a nutshell.
This will only work if you can plot the images by using points.
The for every point that is normally plotted, two points are plotted.
You have to rotate the image one degree to the left and then one degree
to the right. You can do that with the following equations

R = cos(pi/180) : S = sin(pi/180)
xnew1 = xold * r - zold * s
xnew2 = xold * (-r) - zold * (-s)
The y coordinates are the same.
Plot one image blue and the other red.
Put on the glasses, you may have to reverse the colors of the two images

I hope this helps you.
