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.
cubicgrid accepts the following options:
- --window
- Draw on a newly-created window. This is the default.
- --root
- Draw on the root window.
- --window-id number
- Draw on the specified 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 the current frame rate, CPU load, and polygon count.
- --symmetry
Symmetry
- Which crystalographic symmetry system to use. One of "auto",
"cubic", or "hexagonal". "auto" will
randomly select between symmetry systems.
- 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.
- XSCREENSAVER_WINDOW
- The window ID to use with --root.
