Preview_sss_1344__no_cauchy_b_coeff

Fresh human blood (not dried).
150g hemoglobin per liter.
Absorption data is for hemoglobin, but its 95% of the blood dry mass.
Absorption data is from:
http://omlc.ogi.edu/spectra/hemoglobin/
http://omlc.ogi.edu/spectra/hemoglobin/summary.html
Average absorption coefficient was calculated from molar extinction coefficient.
About 88-90% is water.

7400spp
2 supersamples

looks pretty real. nice job! preview render is kind of dark, though.

Meelis said on 15-12-2009:

Yes, i will try to power up emitters.

JonasW said on 17-12-2009:

how do you made the preview picture?

Meelis said on 18-12-2009:

Hi JonasW

In indigo 2.2.9 by opening previewscene.igs from C:\Users\XXX\AppData\Local\Temp\indigo_material_editor_temp_dir
that was saved there by Indigo Material Editor automatically when u 1st started rendering in Material Editor.

It's @640x640 but now i render 500x500 (sharper, no rescaling) and i increase light power 2x to all emitters.

It's test scene by PureSpider:

Thanks!

Material EDITED.
Lower sss (from 3360 to 1344).
Powerd up test scene (by PureSpider) emitters 2x.
Cleaner render 15000spp with 2 super-samples (1st image was rendered without super-s)

It would be great if this was rendered with the database model, just for the sake of consistency.

Meelis said on 01-02-2010:

Hey Soup

I rendered with this model because the material is very hi absorber (~57,3 % of light per 1/1000 m will be absorbed),
and this model has more slimmer geometry

But this material needs optimization anyway:
No need for cauchy b coefficient. Soo I render on default model.

Meelis said on 03-02-2010:

Another EDIT
* Default scene
* No cauchy_b_coeff
