NAME

       voronoi - draws a randomly-colored Voronoi tessellation

SYNOPSIS

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

DESCRIPTION

       Draws a randomly-colored Voronoi tessellation, and periodically zooms in and adds new points.  The existing points also wander around.

       There are a set of control points on the plane, each at the center of a colored cell.  Every pixel within  that	cell  is  closer  to  that
       cell's control point than to any other control point.  That is what determines the cell's shapes.

       When  running  in  a  window,  you  can click  to insert a new point at the mouse position.  Clicking on an existing point lets you drag it
       around.

       This implementation takes advantage of the OpenGL depth buffer to compute the cells for us, by rendering the  intersection  of  overlapping
       cones in an orthographic plane.

OPTIONS

       -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.

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -points int
	       How many points to add each time we zoom in.

       -point-size int
	       How big to draw the stars, in pixels.  0 for no stars.

       -point-speed ratio
	       How fast the points should wander.  Less than 1 for slower, greater than 1 for faster.

       -point-delay seconds
	       How quickly to insert new points, when adding.

       -zoom-speed ratio
	       How fast to zoom in.  Less than 1 for slower, greater than 1 for faster.

       -zoom-delay seconds
	       Zoom in every this-many seconds.

       -fps    Display the current frame rate, CPU load, and polygon count.

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.
