 Visual is a Python module for 3D scientific visualization. It offers
 real-time 3D output and is easily usable by novice programmers.
 .
 A program can create 3D objects (such as spheres, curves, etc.) and
 position them in 3D space. Visual, running in a separate thread,
 automatically updates a 3D scene many times per second to reflect the
 current position of the objects. The programmer does not need to deal
 with display management but can focus on the computational aspects for
 the program. The user can navigate in the 3D scene by using the mouse
 to zoom and rotate while the program is running. Visual supports full
 vector algebra.
