.SH DESCRIPTION
The \fIhypercube\fP program displays a wireframe projection of a hypercube
which is rotating at user-specified rates around any or all of its four axes.
.SH OPTIONS
.I hypercube
accepts the following options:
.TP 8
.B \-window
Draw on a newly-created window. This is the default.
.TP 8
.B \-root
Draw on the root window.
.TP 8
.B \-mono
If on a color display, pretend we're on a monochrome display.
.TP 8
.B \-install
Install a private colormap for the window.
.TP 8
.B \-visual \fIvisual\fP
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.
.TP 8
.B \-delay \fImicroseconds\fP
How much of a delay should be introduced between steps of the animation.
Default 100000, or about 1/10th second.
.TP 8
.B \-observer-z \fIint\fP
How far away the observer is from the center of the cube (the cube is one
unit per side.) Default 5.
.TP 8
.B \-color0 \fIcolor\fP
.TP 8
.B \-color1 \fIcolor\fP
.TP 8
.B \-color2 \fIcolor\fP
.TP 8
.B \-color3 \fIcolor\fP
.TP 8
.B \-color4 \fIcolor\fP
.TP 8
.B \-color5 \fIcolor\fP
.TP 8
.B \-color6 \fIcolor\fP
.TP 8
.B \-color7 \fIcolor\fP
The colors used to draw the line segments bordering the eight faces of
the cube. Some of the faces have only two of their border-lines drawn in
the specified color, and some have all four.
.TP 8
.B \-xw \fIfloat\fP
.TP 8
.B \-xy \fIfloat\fP
.TP 8
.B \-xz \fIfloat\fP
.TP 8
.B \-yw \fIfloat\fP
.TP 8
.B \-yz \fIfloat\fP
.TP 8
.B \-zw \fIfloat\fP
The amount that the cube should be rotated around the specified axis at
each frame of the animation, expressed in 0.001 radians. These should be small
floating-point values (less than 50 works best.) Default: xy=3,
xz=5, yw=10.
.TP 8
.B \-fps
Display the current frame rate and CPU load.
.SH ENVIRONMENT
.PP
.TP 8
.B DISPLAY
to get the default host and display number.
.TP 8
.B XENVIRONMENT
to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
