[ Functionator ]

Functionator is an easy-to-use yet powerful application that allows you to represent functions in form of curves. Simply enter a function like f(x) = x*x and you'll have the corresponding curve drawn. You can then freely scale and rotate the scene and specify how the curve should be drawn. If you have finally drawn your perfect curve, simply save it for later use or export it as an image file. You can also turn anti-aliasing on or off. Functionator is perfect for everyone wanting to play around with curves. Source code is available.
