I've played with creating animations in POV-Ray, and it's
pretty easy, except that each frame of the image gets written to a separate file.
I figured it would be easy to find a tool that smooshed all the frames together into an animated
GIF, but I was surprised when I couldn't find a free tool that did this simple job.
The Gimp is a great image manipulation tool, and will write
an image with multiple layers to an animated GIF, where each layer is a new frame. So I wrote
this script to load the separate image files into layers in Gimp.
This script works under the Windows version of Gimp, and I see no reason why it shouldn't run
on other platforms as well. Copy the script to your script directory (see the Gimp help for help),
and it will appear as the Xtns - Script-fu - Utils - Load Frames.. command.
