What's new in Visual 5 You can leave a trail behind a moving
object simply by specifying make_trail=True: ball =
sphere(make_trail=True) Each time you change ball.pos, this new
position is added to a curve, thereby leaving a trail behind the
moving sphere. This works with arrow, box, cone, cylinder,
ellipsoid, pyramid, ring, and sphere. You can specify using a
points object rather than a curve object for displaying the
trail, and you can specify how many points to skip or retain:
ball = sphere(make_trail=True, trail_type="points", The trail of
this sphere will show individual points rather than a continuous
line, it will display points at every 10th sphere location, and
it will retain only the most recent 50 of these points. At any
time during the moving of the object, you can specify
ball.make_trail=False, in which case no more points are added to
the ball's trail until you set ball.make_t
