3D Grapher is a feature-rich notwithstanding easy-to-use graph plotting and data visualization software appropriate for students, engineers and everybody who needs to function with 2D and 3D graphs. 3D Grapher is diminished, barred, pliable, and reliable. It offers much of the functionality of whale data analysis and graphing software packages for a diminished fraction of their cost. The program is very easy to larn - you don't demand to interpret long manuals to digit out how it works, but can good play with 3D Grapher for several minutes and start working. 3D Grapher provides for three systems of coordinates: Cartesian, cylindrical and spherical. Graphs can be generated from shelve data or from the manually entered equations. You can fix the unlimited number of equations and tables and their graphs will be plotted in one coordinate scheme using different colors and lighting conditions. This feature helps you visualise and dissect the domains and intercepts of several functions. Functions can be parametric, and can include a time variable - this feature allows creation of animated graphs and models. You can easily rotate the created graphs with the mouse, zoom them and view at any angle. Other program features include: 1) Built-in formulation calculator 2) Mouse cursor coordinate tracking 3) Fully customizable user-friendly interface for highly efficient workflow 4) Ability to importation and export data in several popular file formats 5) Ability to copy the graphs and paste them into your own documents 6) Support for OpenGL video accelerators.
