voronoi(6x) XScreenSaver manual voronoi(6x)
voronoi - draws a randomly-colored Voronoi tessellation
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]
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
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.
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.
How many points to add each time we zoom in.
How big to draw the stars, in pixels. 0 for no stars.
How fast the points should wander. Less than 1 for slower, greater than 1 for faster.
How quickly to insert new points, when adding.
How fast to zoom in. Less than 1 for slower, greater than 1 for faster.
Zoom in every this-many seconds.
-fps Display the current frame rate, CPU load, and polygon count.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
