There's something so perverse about such a thing as this,
none the less I suppose you're going to intrigue many people who've
been looking to ray trace cartoons. sigh

Here is another demo image of this filter, a bunch of randomly placed
cones, spheres, and boxes. Next, I am going to work on finding the edges
between colors.

I'm beginning to feel compelled to draw a cartoon picture.
But seriously, this is fascinating stuff.

And here is the version including color edge detection:

This is just too cool. Press on with the work.
I would love to see a tree rendered this way.

wondering how it would look anti-aliased.

I think this is a very good idea. Could you antialias the lines (or are they
antialiased already)?
Also it'd be great if the edges weren't always black but could take the
color from the quickcolor of the objects.

You should figure out how to make the lines antialiased.

I don't know...I can try to smooth them out.

The edges can be any color you want. It is currently impossible to make
per-object filters, that portion of the code is not finished.
