3D Grapher is a program for creating animated 2D and 3D equation graphs and displaying tabular data. Very convenient is that, thanks to this program, received, based on the specified coordinates, graphics can be rotated and moved, and if necessary, to change their scale. Thanks to this, you can view an unlimited number of charts at the same time, each of which is displayed by means of points, lines and surfaces. Presented analytical functions can contain up to three independent variables, including time variables for animation, and are set in parametric form. The coordinates of the cursor location are represented in the three-dimensional coordinate system or on the plane. The necessary animation effect and real-time display of graphics is also carried out thanks to modern hardware accelerators and, used by the program, the graphics library OpenGL. 3D Grapher is very convenient and easy to use.
