Yes, stopping the paint at a colour change is on my to-do list.

I'm not sure if this one will work with uv-mapped textures though... or  
will it?

Yes--but using a slightly different methodology. I.e., instead of shooting rays
from the *camera* into the scene, you could pick an arbitrary point in 3D space
to shoot from--just like trace(). And you could aim the ray in any direction,
again just like trace. Then the ray returns the *color* found on the object.
(Essentially like regular ray-tracing, but maybe even simpler.) And the
object could be a union of many pre-colored objects, even primitive shapes. That
would be the strength of the method, that it doesn't depend on the makeup of the
object, or how many colors it has. Nor would uv-mapping be involved--although
the model could already be uv-mapped if desired, with its many colors.

I'm making it sound simple, but the coding would probably be rather complex.
Then there's the possible parsing/rendering 'circular interaction' I mentioned,
which might defeat the whole scheme, if such an interaction isn't possible. (One
way around *that* might be to do TWO parsing operations: the first for initial
tracing/color evaluating--the results of which are automatically #written to a
file as color vectors-- and the 2nd to #read the results back into the scene for
rendering. I haven't really thought through the details, though.)

I think the white brightens it up nicely :)

WOW! That is looking *so* painterly; what a change from even the previous
render. The blobby paint strokes are looking superb. It's definitely abstract
and Jackson Pollock-ish. But more...understandable!

You may have arrived at new painting 'style' ;-)

Only one suggestion now: Eliminate what looks like the gray plane that bisects
the image; it detracts from the otherwise outstanding results. (IMHO, of
course.)

Added fog and sky. Using a different stroke direction and more strokes.

Aaah! That is the real artist speaking! ;-)

Surrealism! A touch of Yves Tanguy.
