There's no obstacle at present to creating fly-throughs, is there? An
example is stonehenge.py, where one simply updates scene.center and
scene.forward to implement the fly-through.<br>

A measuring stick that uses a simple line drawing tool with point and

The simulation is a Sun/Earth gravity gradient that you can use to
measure the distance of various objects.<br>

New Year wish list:<br>
  <br>
Two new methods for display():<br>
scene.spin : a replacement to scene.forward for reading and writing
user spin input<br>
scene.zoom : a new method for reading and writing user based zoom input<br>
  <br>
This would leave scene.range/scale for defining overall scene settings
and make scene.forward redundant.<br>
  <br>
Scene.zoom should set and get user driven zoom values in the same way
that scene.forward returns user spin values.<br>
  <br>
The purpose of this would be to enable programs to turn on or off
labels and
other objects when user zooms in to field of view or zooms out,
respectively.<br>
Also, such methods would make it very easy to design a Vpython Scene
Animator, driven by a user input stream of spin and zoom and capable of
producing smooth, time based Fly-Throughs of ANY scene.<br>
  <br>
Any how, I'm taking a break for a few days.<br>
  <br>
Happy New Year to Everyone on the mailing list.<br>
