Well, I did a math program [soft-ingenium.planetaclix.pt]. It has 3D graphs with a cool rotation effect. you can see the pictures in the link. To me, the nice thing is that it solves equations and formulas, it has a fast algorithm. Other stuff like matrix’s, complex numbers, …
So, now I am a Qt Ambassador :)
I have released a new beta version of MathGraphica. It’s a full rewrite in Qt5, with lots of improvements in matrices, graphs rewrite in opengl shaders, many fixes in the UI, and others goodies.
The sources are in gitorious, also made a Windows installer and zip portable, check here: MathGraphica [qt-apps.org]
