Paraibas by Schmiegel Paraibas by Schmiegel
Gems and stuff ignoring any scales - and knowing that.

I love tourmalines.

This image does not look like tourmalines. Their refraction and dispersion is different. However on a trade show I once saw a green/blue/pink set of paraiba tourmalines. They looked so amazing - far better - anyway, I loved them and took them as a maverick to make that image.

The gem shape is based on Cut Diamond by Thingyverse user M_G. (I fixed a problem that interfered with transparency)

Refrained from retouching the stripes on the main faces - seems to be a flaw from remeshing and smoothing in Blender.

Arranged & textured in Blender, rendered using Yafaray (Direct Lighting @ 32 aa samples for speed & noise reduction).

Porting for LuxRender not yet successful as I don't get the writing mapped to the label on the floor …
(but the gems look damn hot in Lux! :) )


P.S.: Would make nice Kunzites too - just need a pleochroism plugin for Blender ... ;)

really cool image =)
Did you do something special to reach that kind of dispersion effect as seen on the geen and purple stones?

Danke Dir :)

Das ganze Bild dreht sich um optische Effekte - ich bin noch auf der Suche nach Pleochroismus, den Rest können gute Renderer inzwischen. :)

I went for Yafaray to render the image because there I can define the amount of dispersion as desired. All 4 gems use the same dispersion value - so here's where the guessing begins:
a) The large stones might show more dispersion as the effect of dispersion is more visible when refracting through slightly rounded faces (added intentionally). Rounding is barely visible for the small stone.
b) The blue stone filters the orange tones, thus dispersion is less visible there.
a)+b) leave green and purple with 'good' dispersion.
