cubicgrid - rotating 3D lattice seen from inside


cubicgrid [-display host:display.screen] [-visual visual] [-window] [-root] [-install] [-delay microseconds] [-mono] [-speed number] [-zoom number] [-ticks number] [-bigdots] [-fps]


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.
-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.


DISPLAY 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.
