Mathematical graph and charting software for geometry and statistics

The calculator can do statistics, best fits, function plotting, integration. It handles vectors, matrices, complex numbers, quaternions, coordinates, regular polygons and intersections.

For point, line, plane, sphere, circle Calc 3D calculates distances, intersections, and some additional information like volume and area.

Cartesian, spherical and cylindrical coordinates can be transformed into each other.

Carthesian plot, polar plot, parametric plot, best fit, fast fourier transformation, histogram, smooth,...

Several languages can be handeled.

  • Calc 3D Pro is now free, donations are welcome !

    To develop a program like this needs a lot of time and patience. In the past this program was sold like shareware.
    Doing this on the one hand I was excluding people who didn't have the money, on the other hand it didn't cover the expenses.
    So I decided to convert the program to freeware.
    Please write me, if you are interested in sponsoring.
    If you like the program and think, that it is useful, it would be nice, if you send me an amount, that is suitable for you.
