3D pictor released 3D Graph as a freeware. As a calculus student I was always fascinated by the shapes of 3d functions. After a short while I decided to give shape to the functions I learned about and the result was 3D Graph! Click the java applet and drag to rotate around the axis You can use the following functions: +, -, *, /, sin(), cos(), ^, pi example functions: sin(x*180/pi)-cos(y*180/pi) (x^2-y^2)/10 (x^2+y^2)/10 x/y The first version was written in Boarland C and works well on Dos 6.2.2 as well as on Windows 95 (It was back in 1997) but a short while ago, as I was going over some old folders on my computer I saw 3D Graph and thought it would be nice to share this small application. Well, you may find the old version working with 95 compatible systems but I released a newer version of the application so now you can use an easy to use windows version of 3D Graph Today you can even try it without downloading by using the 3D Graph java applet in this page. Please try it and let me know what you think. I"d appreciate feedback, bug reports and enhancement suggestions to webmaster@3dpictor.com
