program draws an animation of an asteroid field moving past the
observer (or vice versa). Sometimes the observer picks up spin on Z axis.
accepts the following options:
- Draw on a newly-created window. This is the default.
- Draw on the root window.
- Make all the rocks the same color.
- -ncolors colors
- How many different colors to use. Default 5. Colors are
- Install a private colormap for the window.
- -visual visual
- Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific visual.
- -count integer
- Maximum number of rocks to draw on the screen at once.
- -speed integer
- A measure of the speed with which the observer and the
rocks pass each other, from 1 to 100. Default 100, meaning ``very fast.''
If you're on a slow display connection (the animation looks jerky) then
try making this number smaller, and/or decreasing the number of
- -delay microseconds
- Number of microseconds to delay between each frame. Default
50000, meaning about 1/20th second. Compare and contrast with
- Don't rotate the observer; just fly through the field on
- Don't turn the observer; just fly straight ahead through
- Do red/blue 3d separations: if you look at the screen with
3d glasses, the rocks will be jumping right out at you.
- Display the current frame rate and CPU load.
- to get the default host and display number.
- to get the name of a resource file that overrides the
global resources stored in the RESOURCE_MANAGER property.
There should be an option to display doppler shift (a gravity rainbow.)
Speed of rotation should be settable.
Default speed of rotation should be relative to forward velocity.
