my last milk

I played again a bit with this milk glass. Basically I just changed the lighting: now it is an env map from evermotion which i converted to exr. I am pretty satisfied, but still I dont understand why using the h-g coefficients from Jensen I get something wrong... here I just put g uniform and = 0.

ashtray (?)

I modeled this "thing" playing with MoI, and then I decided to use it to test dispersion in Indigo. This is the result.

In your model the glass "balls" are a whole solid or did you model also their thickness and put air inside?
If it is the first, maybe this could explain why you don't see reflections...

Nice job!

Well, I owe one of those galileo thermometer and I can see no white in the middle of the drops! Another point: to me the drops and their glass "balls" seem a bit "flat", i.e. with almost no reflections from outside...

... while these are with h-g coefficients from jensen paper.

...

... yeah, I am afraid of you guys! If you say that photos looks "promising"... ! :D Anyway, i have tried in these days to emulate the light condition of the two photos. These are the results. Still not 100% happy but... BTW, I am having problems with the henyey-greenstein coefficients. In these two ...

milk experiments!

This evening I did a couple of experiments at home with REAL milk to better understand how its SSS work. Am I a physicist or not, after all ? :) I tried to put on a similar lighting condition as in the render. What I understood (maybe it is obvious to you) is that the SSS depends critically on the k...

[quote="Kram1032"]you don't need to subdivide it, you rather can smooth the normals....
To get save, do both together though^^

Smooth the normals ?? What does it mean? :?:

I was expecting this kind of comments :) ... the milk is faceted because of a fault of mine: I did not subdivide my model enough, and when I realized it it was already a few hours of rendering. Anyway, it can be easiliy fixed. About the milk appearance: i am pretty sure about scale and everything. A...

Subsurface scattering: my first work

Hi! I am a PhD student in Physics, and I work in the field of optics. So guess how I was excited by the physically accuracy of INDIGO! This is my first serious render, to test how the absorption and scattering properties of the materials are rendered. I am a noob, but this is fantastic, to me. The l...
