Gemstones

Post by Meelis » Wed Nov 10, 2010 8:08 pm

Hi :D

Here are my gemstones in attachment (zip) , also some of them are in MDB like Amethyst, Topaz and Emerald.
So i don't need to upload if the default material preview scenes look similar.

Most of the absorption is from http://minerals.gps.caltech.edu/FILES/V ... st_AZ.html
Most dispersion data is computed from n @ different wavelength found at http://www.mindat.org/
and from other sites.

Some more will be added in future, and plz recommend gemstone that you would like to see.

I do understand i need default scene for preview to upload in MDB, but i had few problems with that,
like i wanted to use halt 2000 SPP, Aperture Diffraction on, MLT with BIDIR
Also most of the materials need very thin / small medium to not look black because in reall life they are used also for very small gems.

Also from larger gemstones u can see there is some SSS, so i experiment with that when i get back home from Norway in 1,5 months or so.
U can google image search "gemstones scattering"
for example Kazakhstan Jadeite has some SSS.
