Function Grapher is a easy-to-use software for 2D,2.5D and 3D function graphing and animation.2D and 2.5D function graphs can be plotted in Cartesian and polar coordinate systems,and 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 2.5D and 3D graphs such as color, material, model and smoothness. Other objects such as light,axis and view are all in your control.
