voronoi(6x) XScreenSaver manual voronoi(6x) 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. SEE ALSO

carousel(6x) XScreenSaver manual carousel(6x) NAME
carousel - displays multiple images rotating in a circular formation SYNOPSIS
carousel [-display host:display.screen] [-visual visual] [-window] [-root] [-count int] [-zoom | -no-zoom] [-tilt XY] [-titles | -no-titles] [-font font] [-speed ratio] [-duration seconds] [-fps] [-debug] [-wireframe] DESCRIPTION
Loads several random images, and displays them flying in a circular formation. The circle changes speed and direction randomly, tilts on its axis, and the images move in and out. This program requires a good video card capable of supporting large textures. To specify the directory that images are loaded from, run xscreensaver-demo(1) and click on the "Advanced" tab. 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. -count int How many images to display. Default 7. -zoom | -no-zoom Whether the images should move in and out (toward and away from the axis of rotation). Default true. -tilt XY | -no-tilt Whether the axis of rotation should tilt, and how. -tilt X means that it will tilt toward and away from the viewer. -tilt Y means that it will tilt to the left and right of the screen. -tilt XY (the default) means it will do both. -titles | -no-titles Whether to display the file names of the images beneath them. Default: yes. -font font-name The font to use for titles. Note that the size of the font affects the clarity of the characters, not their size (it is auto- scaled.) -duration seconds Every duration seconds, one of the images will be replaced with a new one. Default 20 seconds. -speed ratio Speed up or slow down the animation. 0.5 means half as fast as the default; 2.0 means twice as fast. -delay number Per-frame delay, in microseconds. Default: 20000 (0.02 seconds.). -fps Display the current frame rate, CPU load, and polygon count. -debug Prints debugging info to stderr. -wireframe Another debug mode. 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. SEE ALSO
