Took a couple of days to put the diamond together using math (no GUI, plain
text)
This was a test run (aren't they all..)
The diamonds are 1 POV unit in diameter.
global_settings {
photons { spacing 0.08 count 5000 }
max_trace_level 60
}
light_source { < -11, 40, -7 >, White*2 parallel point_at <0,0,0> }
Box under diamonds
------------------
finish { ambient .05 diffuse .6 reflection .1 }
photons { target 1 refraction off reflection off }
Diamonds
--------
finish { ambient 0 diffuse 0.2
specular 0.8 roughness 0.003
phong 1 phong_size 400
reflection { 0.15, 0.05 fresnel metallic }
}
interior { ior 2.417 dispersion 1.044 dispersion_samples 30 }
photons { target 1 refraction on reflection on }
