Function Grapher is a easy-to-use software for 3D function graphing and animation.3D function graphs can be plotted in Cartesian,cylindrical and spherical coordinate systems.Function Grapher has the ability to set and modify the properties of 3D graphs such as color,material,model and smoothness.Other objects such as light,axis and view are all in your control.

Features:

Ability to implement 2D and 3D calculator graphing. By extending the third dimension, 2.5D graphs of 2D functions can be created.
For 2D functions, grapsh can be plotted in Cartesion and polar coordinate systems; for 3D functions, graphs can be plotted in Cartesion , cylindrical and spherical coordinate systems.
Ability to create 2D, 2.5D and 3D animations.
Ability to set and modify the color and width of 2D and 3D curves.
Ability to set and modify the color, material, model style and smoothness of 2.5D and 3D graphs.
Ability to customize the appearance of axis and the parameters of light.
Ability to save graphs as pgp format or bmp format.
Ability to cut, copy, paste and delete graph(s).
Ability to move, zoom and rotate the scene.
A free calculator - Math Calculator is provided.
Ability to render the scene view from the front, the right and the top.
