Description
This program shows the view of an observer located inside a set of points arranged to a 3D lattice. As the
lattice rotates, various view-throughs appear and evolve. A simple idea with interesting results.
Options
cubicgrid accepts the following options:
- -window
- Draw on a newly-created window. This is the default.
- -root
- Draw on the root window.
- -install
- 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.
- -delay microseconds
- How long to pause between frames. Default is 20000, or 0.02 second.
- -mono
- Draw in black and white. If not used, a fixed all-color scheme is chosen.
- -speed number
- The maximum speed of the rotation. The actual speed and axis change smoothly for better effect. 0.5 - 10. The default is 1.0.
- -zoom number
- Size of the lattice. Ideally it should fill all the screen, but one may find other values also interesting. 5 - 50. The default of 20 should do for common
screen aspect ratios.
- -ticks number
- The count of points drawn along every axis. 10 - 100. The default is 30.
- -bigdots
- Draw the points twice as big.
- -fps
- Display a running tally of how many frames per second are being rendered. In conjunction with -delay 0, this can be a useful benchmark of your GL
performance.
Environment
- DISPLAY
- to get the default host and display number.
- XENVIRONMENT
- to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
