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. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
