SYNOPSIS

9       voronoi  [--display  host:display.screen]  [--visual visual] [--window]
10       [--root]  [--window-id  number]  [--points  int]   [--point-size   int]
11       [--point-speed  ratio]  [--point-delay  seconds]  [--zoom-speed  ratio]
12       [--zoom-delay seconds] [--fps]

DESCRIPTION

15       Draws a randomly-colored Voronoi tessellation, and  periodically  zooms
16       in and adds new points.  The existing points also wander around.
17
18       There are a set of control points on the plane, each at the center of a
19       colored cell.  Every pixel within that cell is closer  to  that  cell's
20       control point than to any other control point.  That is what determines
21       the cell's shapes.
22
23       When running in a window, you can click  to insert a new point  at  the
24       mouse position.  Clicking on an existing point lets you drag it around.
25
26       This  implementation takes advantage of the OpenGL depth buffer to com‐
27       pute the cells for us, by rendering  the  intersection  of  overlapping
28       cones in an orthographic plane.

OPTIONS

31       --visual visual
32               Specify  which  visual  to use.  Legal values are the name of a
33               visual class, or the id number (decimal or hex) of  a  specific
34               visual.
35
36       --window
37               Draw on a newly-created window.  This is the default.
38
39       --root  Draw on the root window.
40
41       --window-id number
42               Draw on the specified window.
43
44       --points int
45               How many points to add each time we zoom in.
46
47       --point-size int
48               How big to draw the stars, in pixels.  0 for no stars.
49
50       --point-speed ratio
51               How  fast  the  points  should wander.  Less than 1 for slower,
52               greater than 1 for faster.
53
54       --point-delay seconds
55               How quickly to insert new points, when adding.
56
57       --zoom-speed ratio
58               How fast to zoom in.  Less than 1 for slower,  greater  than  1
59               for faster.
60
61       --zoom-delay seconds
62               Zoom in every this-many seconds.
63
64       --fps   Display the current frame rate, CPU load, and polygon count.
65

ENVIRONMENT

67       DISPLAY to get the default host and display number.
68
69       XENVIRONMENT
70               to  get  the  name of a resource file that overrides the global
71               resources stored in the RESOURCE_MANAGER property.
72
73       XSCREENSAVER_WINDOW
74               The window ID to use with --root.
