[Visualpython-users] tools

[symion <sy...@pr...>]

Here is another program related to big spaces. MeasuringStick.py 
<http://home.primusonline.com.au/knoware/python/measuringstick.py>
A measuring stick that uses a simple line drawing tool with point and click.
The simulation is a Sun/Earth gravity gradient that you can use to 
measure the distance of various objects.

New Year wish list:

Two new methods for display():
scene.spin : a replacement to scene.forward for reading and writing user 
spin input
scene.zoom : a new method for reading and writing user based zoom input

This would leave scene.range/scale for defining overall scene settings 
and make scene.forward redundant.

Scene.zoom should set and get user driven zoom values in the same way 
that scene.forward returns user spin values.

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.
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.

Any how, I'm taking a break for a few days.

Happy New Year to Everyone on the mailing list.
