The world of POV-Ray crystallography is on fire this week... after the
discovery of Thomasite, now it's the turn of Vivesite. ;)
The crystals are procedurally generated using triangle meshes from the
scratch. A height_field was used to trace the 4 base points, and then
the crystal was grown following the normal at the center point. No area
light nor radiosity this time... but I used photons+dispersion and a
strong focal blur. Render time was a under 2 hours using an AMD FM-6300
(x6).
As the test seems to have given acceptable results, I'm going to use now
an isosurface as the base, and try to use hexagonal crystals... if I can
work it out: working out the maths for a cube basal I already fried one
or two neurons...

A very nice result, imho.

Excellent ! Looking forward for the next one. Hope you have some neurons left.

That's incredibly good. :)

I guess it's worth frying a few more ;)

First test using an isosurface as base... nice, except for some ugly
artifacts on focal blur, due to a too strong light source.

Fantastic. I've been wanting to know how to do this for years, but good crystal
geometry has been elusive.
How high do you have to set the max_trace_level?

Phantastic!
Good to see something new from you, Jaime.
First I thought, it's hdr lighting, but with this artifacts...
