Re: silly shader question : curvature convex and concave.

I have ended up with a ray traced approach, using a disk like an
umbrella where rays are cast from the spokes of the umbrella paralell to
the stem of umbrella and measure if they are longer or shorter than the
stem itself.

longer : convex
shorter : concave

Bakes of these were handed over to texture artists.
