The final version of POV-Ray filters:
filters.inc - include file
artists.pov - for testing filters
birds.png - Escher pattern

Thanks so much for this excellent work. The new filters are really
surprising, especially the Paris Art Museum!
I would like to try and animate this one and have the black squares appear
at random places throughout the canvas. Any ideas on how to accomplish that?
Thanks very much for your work.

I've never done animation with POV-Ray. Anyway, you
can try the following approach. Just make the image with
indexed colors (see PNG example in attachment) and make
a loop through all colors (0 - 255) in your pigment block:
#declare tahoe = pigment {
image_map{
png "tahoe.png"
map_type 0
interpolate 0
transmit 40, 1 // make loop here. Right now it will make color number 40 as
transparent
once
}
scale <4/3, 1, 1>
}
Hope this helps.

I was using a scanned image of a Kandinsky picture for my image. Is there
any way to use indexed colors with a preexisting scanned image?
thanks again.

I know that in Photoshop the image can be saved with indexed colors
in GIF, PNG and TGA format. But there are 256 colors only. I don't know
if it's possible to overcome this restriction.
