VPython reference page for animation functions and constants. This page assumes and only includes basic usage of VPython.
VPython Template
from __future__ import division
from visual import *
## Constants
## Initialization
## Loop
t = 0
deltat = 1e-10
end = 10
while t < end:
rate(1000)
## Loop Code
t += deltat
