Usage

Overview

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.

--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.

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.

XSCREENSAVER_WINDOW

The window ID to use with --root.
