NAME

        klein - A Klein Bottle (and other parametric surfaces) visualization.
 

SYNOPSIS

        klein [-display host:display.screen] [-visual visual] [-window] [-root]
        [-speed number] [-rand] [-spin] [-wander] [-fps]
 

DESCRIPTION

        This draws a three dimensional visualization of a Klein Bottle paramet-
        ric surface (the three dimensional equivalent of the Moebious strip).
 

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.
 
        -delay number
                Per-frame  delay,  in  microseconds.  Default: 20000 (0.02 sec-
                onds.).
 
        -speed number
                Number of frames before changing shape.  Default: 150.
 
        -rand   Randomize the parametric surfaces displayed. Use random  OpenGL
                primitives  too.  -wander | -no-wander Whether to wander around
                the screen.  -spin | 0-spin Whether to rotate around the centre
                of the figure.
 
        -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.
