Software

Copy and paste the following file as uFly.py.

from visual import *

def rotate_view(angle=0, raxis=(0,0,1),
                 nsteps=1, drate = 30):
    '''rotates view by angle degrees about the raxis using nsteps steps with an animation rate of drate'''

    if nsteps == 0:
        print "nsteps must not be equal to zero"
    dangle = radians(float(angle)/float(nsteps))
    for i in range(nsteps):
        rate(drate)
        scene.forward = rotate(scene.forward, dangle, raxis)
