RENDERER USED: 
    POV-RAY 3.0


TOOLS USED: 
    cmpeg (for MPEG-1 packing) with options -d1 and -m1 for high
   quality.


CREATION TIME: 
    Planning 2h Rendering 3h 30m, MPEG-1 encoding 2h 45m
(approximately)


HARDWARE USED: 
    AMD 486 133 MHz with 52 MB of RAM and Tseng ET6000
graphics    accellerator.


ANIMATION DESCRIPTION: 
    The fourth dimension has always intrigued me. If a
four-    dimensional object 'falls' through three-dimensional space,     a
3D-'slice' of it will show up in our world. This object,     made with the
powerful 'julia'-object in povray 3.0, does     exactly that. Rotating and
changing color as it visits out     3D world. (Changing color? So this is -
strictly speaking -     a 5D object, but who cares?) This was all inspired by
the     fractals in the sample scenes accompanying povray. The     final
product looks a bit like a lump of silly putty     constantly changing shape
and size under the influence from     rotational forces. Or maybe the sweet
stuff used in candy-    making?


VIEWING RECOMMENDATIONS: 
    I suggest vmpeg.exe for DOS or vmpegwin.exe /
  vmpegwing.exe for Windows 3.11/95/NT.


DESCRIPTION OF HOW THIS ANIMATION WAS CREATED: 
    I used sine functions to alter
the            color and rotation of the fractal object. The 'slice' was    
done by changing one of the slice vector components. The     frames was
rendered with clock values from 0 to 1, but I     thought, after vieving a test
rendering, that it would be     nice to have the object come out of 'thin air'
and     vanishing again, so I put in an extra frame with a clock     value of
1.5, resulting in a frame withoout any sign of the     object. Then I put this
extra frame in a couple of     instances at the beginning and at the end of the
.INI     sequence before encoding the frames with cmpeg.
