an (not very successfull) attempt to render the happy buddha with patina. I
use a patched version of megapov with a new pattern which send a bunch of
rays, and check if they intersect an object (see the red&blue picture)
(btw, if someone have a good patina texture i m interested :)

Hmmm... I think it's quite good. It gives the look of a badly
cleaned antique. Maybe the bump map isn't quite right...
No smooth enough but very good nonetheless...
Do you have this mesh in regular POV mesh format ?
Best,

The pattern looks fine. Can it be combined with slope to
give it directinal bias?

Nice, i think Chris Huff was working on a similar patch too. Does it
generate smooth transits or are there steps in the pattern value?

it should be smooth transition : you give the number of samples you want,
and the pattern return (nb_samples_hit)/(nb_samples). It uses the same
hemisphere distribution than the blur for reflection
i was thinking about adding a max_distance, so that if the ray intersect the
object too far, it does not count as an intersection.

i think it can be combined as all other pattern
(but you can't use it in eval_pattern/eval_pigment because it needs the
normal of the object)

i have it in mesh2. Converted from the .ply format you can find here :
