| 7 | .SH DESCRIPTION |
|---|
| 8 | The \fIhyperball\fP program displays a wireframe projection of a hyperball |
|---|
| 9 | which is rotating at user-specified rates around any or all of its four axes. |
|---|
| 10 | .SH OPTIONS |
|---|
| 11 | .I hyperball |
|---|
| 12 | accepts the following options: |
|---|
| 13 | .TP 8 |
|---|
| 14 | .B \-window |
|---|
| 15 | Draw on a newly-created window. This is the default. |
|---|
| 16 | .TP 8 |
|---|
| 17 | .B \-root |
|---|
| 18 | Draw on the root window. |
|---|
| 19 | .TP 8 |
|---|
| 20 | .B \-mono |
|---|
| 21 | If on a color display, pretend we're on a monochrome display. |
|---|
| 22 | .TP 8 |
|---|
| 23 | .B \-install |
|---|
| 24 | Install a private colormap for the window. |
|---|
| 25 | .TP 8 |
|---|
| 26 | .B \-visual \fIvisual\fP |
|---|
| 27 | Specify which visual to use. Legal values are the name of a visual class, |
|---|
| 28 | or the id number (decimal or hex) of a specific visual. |
|---|
| 29 | .TP 8 |
|---|
| 30 | .B \-delay \fImicroseconds\fP |
|---|
| 31 | How much of a delay should be introduced between steps of the animation. |
|---|
| 32 | Default 100000, or about 1/10th second. |
|---|
| 33 | .TP 8 |
|---|
| 34 | .B \-observer-z \fIint\fP |
|---|
| 35 | How far away the observer is from the center of the cube (the cube is one |
|---|
| 36 | unit per side.) Default 5. |
|---|
| 37 | .TP 8 |
|---|
| 38 | .B \-xw \fIfloat\fP |
|---|
| 39 | .TP 8 |
|---|
| 40 | .B \-xy \fIfloat\fP |
|---|
| 41 | .TP 8 |
|---|
| 42 | .B \-xz \fIfloat\fP |
|---|
| 43 | .TP 8 |
|---|
| 44 | .B \-yw \fIfloat\fP |
|---|
| 45 | .TP 8 |
|---|
| 46 | .B \-yz \fIfloat\fP |
|---|
| 47 | .TP 8 |
|---|
| 48 | .B \-zw \fIfloat\fP |
|---|
| 49 | The amount that the ball should be rotated around the specified axis at |
|---|
| 50 | each frame of the animation, expressed in radians. These should be small |
|---|
| 51 | floating-point values (less than 0.05 works best.) Default: xy=0.01, |
|---|
| 52 | xz=0.005, yw=0.01. |
|---|
| 53 | .SH ENVIRONMENT |
|---|
| 54 | .PP |

|---|
| 59 | .B XENVIRONMENT |
|---|
| 60 | to get the name of a resource file that overrides the global resources |
