 NAME
      t3d - clock using flying balls to display the time

 SYNOPSIS
      t3d [  options ]...

 DESCRIPTION
      Time 3D is a clock. It uses flying balls to display the time. This
      balls moves and wobbers around to give you the impression your graphic
      workstation with its many XStones is doing something.

      t3d uses mouse and keyboard to let you fly through the balls. Hit S to
      speed up, A to slow down, Z to zoom in and X to zoom out.  Use the
      left mouse button to rotate to the left and the right mouse button to
      rotate the view to the right. Use the middle mouse button to change
      the optical axis and the moving direction.  Q will stop you.

 OPTIONS
      -display host:dpy
           Specifys the display in the usual way.

      -geometry WxH+X+Y
           Sets the size and location of the t3d window.

      -move factor
           Modifies the direction move of t3d. The clock looks 30 degrees*
           factor to the left and to the right periodically.

      -wobber factor
           Modifies the "wobbering" (sounds nice :-) of t3d by multiplying
           the default deformation of the clock by factor.

      -nice factor
           Renices t3d by factor because t3d uses your process time. The
           default renice factor is 20, so you can't do anything wrong by
           not renicing t3d. If you want more speed, you should set nice to
           a smaller value.

      -minutes
           Shows one small ball for every minute, instead of one for every
           2.5 minutes.

      -mag factor
           Changes the magnification of t3d. By default, t3d uses a 200x200
           window. A factor of 2 means, it will use a 400x400 window.

      -cycle period
           Sets the moving cycle to period seconds. By default, this value
           is 10 seconds.

      -wait microsec
           Inserts a wait after drawing one view of the clock. By default,
           t3d waits 40 ms after each drawing. This helps you to keep the
           performance loss small.

      -fast precalc radius
           t3d uses bitmap copy to draw precalculated balls. You can specify
           the radius in pixels up to which t3d should precalculate balls.
           t3d will set a useful range by itself using the magnification
           when it is started.

      -colcycle
           Draws cyclic the color scale used for the balls in the background
           instead of the normal black.

      -rgb red green blue
           Selects the color in RGB color space of the lighning spot on the
           balls.  All the other colors used for balls or -colcycle are less
           intensive colors of the same hue and saturation. All values in
           range of 0 to 1.

      -hsv hue value saturation
           Selects the color in HSV color space.  hue is in degrees from 0
           to 360, all other values in range of 0 to 1.

      -hsvcycle speed
           Rotates the hue axis every 10 seconds* speed.

      -help
           Prints a short usage message.
