SSS tests
SSS tests
Some sub-surface scattering tests.
The second one has more absorption, and also a specular material at the interface.

Hey, that's nice you're working on that Ono ! I've got a lot of questions tho
1) How fast is it to converge, say compared with Cauchy's dispersion ?
2) Is that a) simple or b) true scattering, and (optionally) if b) what's your estimation of the average # of scatters occuring within the object ? Maybe if that's too long to converge that would be cool to be able to switch between both modes ?
3) Can you post an image with a stronger effect please
4) When is the next release of Indigo (optional Q too)
Thx

1)
Hard to say how fast it is in general.
The images above took about an hour and 30 mins respectively.
The speed will depend on a lot of factors
2)
it's true unbiased multiple subsurface scattering.
The examples are showing uniform isotropic scattering. The number of scatters depends on the scattering and absorption coefficients. Frankly i have little idea how many scatters are occurring in the above images, but it may be 10 scatters or more on average per ray.
EDIT: the 'fake SSS' (glossy transmission) will still be available as a material, so you will be able to take your pick between the two, or even combine them.
3) The effect is very strong, in the first image, the colour and scattering properties of the buddha and sphere are entirely due to absorption and scattering.
I'm gonna work on some forwards scattering which should give a more familiar SSS effect
4) heh, dunno, will be a little while tho

Wow, sounds cool!
2 is indeed very funky.
Anyway, enough questions, onto the kudos:
KUDOS

Is that currently available? (in released versions?)EDIT: the 'fake SSS' (glossy transmission) will still be available as a material, so you will be able to take your pick between the two, or even combine them.
Whats the difference between this and forward scattering?I'm gonna work on some forwards scattering which should give a more familiar SSS effect Smile

forwards scattering is when the light is scattered more in the direction it was heading, as opposed to uniform scattering, where it is scattered equally in all directions.

Dunno, i'm still working on the materials that will be used for stuff like skin.arneoog wrote:AWSOME
*I will make so many candles when I get my hands on this!*
EDIT: in the SSS, do you have controls for the external color (Skin)
and the internal color (flesh)
I hope so
(probably some kind of glossy dielectric material)
