You want to see bloat you should see the file sizes this type of
utility produces even with small images for the input file.

P.S. I have tried contacting the original author of TGADOT and was
not successful in finding an active email address for him.

True, the original TGADOT doesn't have the ability to average pixels
to reduce object count, doesn't have the built-in clock variable, or
rotations, but the source code is readily available for anyone who
wants to port it or add enhancements. I was under the impression that
TgaMosaic wasn't availablie in source code. Am I mistaken?

It's a fine way to emulate a low resolution in a high resolution pic :)

I have done something very similar to this using my eval_pigment() 
patch. Just call the eval_pigment() using the center location of each 
sphere and a pigment which uses an image_map, and use the returned color 
in a solid pigment for each sphere. The results would be the same as 
this. Plus, you can use any pigment, not just an image_map, and every 
file format POV supports is supported(not just TGA).
It also can use the interpolation built in to image_map...

And it isn't bloat, it is a useful feature which only took a small 
amount of code to implement.(although I think it currently only returns 
the rgb values, I haven't modified it to return f and t yet)

Is the 'eval_pigment' going to get into MegaPOV someday?

Probably. I really don't know, and the people in charge of MegaPOV might 
want to wait until it works with filter and transmit. I will try to get 
to work on that...

Thanks. I recalled the images from some time ago when he released it. Some quite
nice things then. Well. Thanks and cyas :)

Kind of like an add-on for the trace function?

Ken

I am curious about this image. At first I thought
it was a dyslexic stereogram:)
I wonder why you mirrored Mona,
for aesthetic or technical reasons.

Thanks for pointing out the benefits of TgaMosaic. I've
been using TGADOT.
