Excellent!

This is a great-looking effect.  If that pear were a guitar,
this would make a good album cover for a psychadelic band.

Great work ...

Great work. I wonder, have you tried processing frames of an animation or video with
this
technique? Is it randomised (causing flickering), or would the effect be quite stable?

All the best,

I assume you are sampling a photo?

You would be assuming incorrectly ;)

Started off with a piece of  graph paper and a pencil, just drew the shapes
of the pear and orange and their shadows, then using Chris Colefax's spline
macros created some splines that corresponded with the shades.  I used a
macro I wrote to calculate whether a set of randomly generated x,y coords
are contained within a specific closed spline so I could "color" the shape.

It actually works pretty well.  Once you have your basic shapes splined into
the system, you can put pretty much any object or texture or whatever you
want into it.  The sucky part is the macro I wrote is sooooooooo
sloooooooow, so I have to write the results to disk to avoid 300 year parse
times....

I've never tried it with an animation yet - it's feasible, just tricky
working out the movement of the spline (but that's not a situation unique
to me - I think something was mentioned in povray.general about the same
thing recently) ...

thanks for the comments!  :)

I really like your experiments. I've never seen such a pear but
that doesn't harm the image a bit. I've visited your site, saw
some pretty goofy graphics but I think the fruit pieces you
posted here lately are among the best things in POV I've seen
sofar.
Please post more.
I'd also like to know how you did it, but I probably won't
understand anyway...

Cheers!

Wow... thanks!  Considering the wonderful works from others I've seen here,
that's a heady compliment :)

Well, as noted before, I just sketch out an image, generate some splines to
trace the shapes in that image, and use several macros to generate blobs or
spheres within the shapes.  That's really all there is to it. :)

I love these bright images you keep inflicting on us ;) They make a
change from the usual RL ones.
They look as if they have been done with thick paint on a non-stick
surface, then you see the reflecting base and you start wondering.

I am much in agreement.

The glossy, gooey look of this one reminded me of pop art
paintings, done with acrylic paint that was squeezed directly
from the tube.

Yeah, but how are you doing those random looking brush strokes 'outside' the
spline? I'm liking those, a lot.
