- This picture was rendered using Persistence of Vision v1.0 from August 2 to
- August 6, 1992. More than anything, it is an experiment that turned out a
- very nice picture. It was first rendered on an Amiga 2000 with a 68000cpu
- and 5megs of RAM. It was then rendered on an SGI Iris 4D. The render time
- indicated in the Amiga trace stats is slightyly longer than it could have
- been since I ran the trace as a background task while running other tasks
- (including a couple of other renders with POV). It was rendered with a
- resolution of 640x480 and converted to 320x400 HAM and 640x480 GIF using
- Art Department Professional v2. Since the size of the picture was
- reasonable, I didn't convert it into JPEG format.
-
- The trace statistics for Amiga and Iris follow for those who are interested.
- The Iris rendered the scene 67.7 times faster than a stock Amiga 2000. The
- picture included here came from the anti-aliased Iris render.
