Graphing Calculator 3D from Runitor is a handy and free 3D graphing utility that plots graphs for two-and three-dimensional mathematical functions and coordinates tables. It supports parametric equations and Cartesian and polar coordinates in 2D and 3D, inequalities in 3D, and other capabilities. It boasts dazzling 3D graphs with seemingly limitless variations. You can change the color, shading, and appearance of graphs, add animation and other features, and rotate and zoom them in real time. You can define your own functions and variables or use one of over 20 provided functions.
Graphing Calculator boasts an attractive and functional if slightly cluttered interface that the developer claims was designed with frequency of use in mind. There's no doubt that it's logically configured, but it's certainly geared toward those with the knowledge and skills to need or use graphing software. To the mathematically challenged, it's a little intimidating, but the program isn't difficult to learn or use. Among its handy time-savers are instantaneous plotting with each keystroke and single-click access for frequently used tools and features. The three-dimensional graphs it produces are stunning, with high color contrast, animation, full rotational motion.
Graphing Calculator 3D is fully compatible with Windows 7. Unfortunately, the freeware version comes with numerous limitations, such as only five graphs, lessened graph resolution and mathematical precision, and an inability to save, open, copy, or print graphs or to import and export coordinates. You can purchase Standard and Professional versions of Graphing Calculator 3D that offer more features and capabilities.
