Hi Bob,

What would you think about doing a brief writeup about these tracing techniques for our articles section?

There is an article on Slashdot that mentions a "new photographic technique" with some concepts strikingly similar to how the Tracer works:

this is the quoted article:

Notice the mention of a "canny edge detector." ;-)

One thing that someone showed me, is how tracing the same image multiple times with different algorithms and/or parameters, and recombining the results, can often produce a fairly good rendition of the original. Here is a trivial example of the raytracer doing it with merely 3 different levels of brighness threshold:

So, hey, we are ahead of the curve on this one! ^^
