NAME

6       voronoi - draws a randomly-colored Voronoi tessellation

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

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

ENVIRONMENT

62       DISPLAY to get the default host and display number.
63
64       XENVIRONMENT
65               to get the name of a resource file that  overrides  the  global
66               resources stored in the RESOURCE_MANAGER property.
