yet some more papers

Post by Kram1032 » Fri Feb 06, 2009 1:31 am

On the bottom of this page, there is a nice list of papers... maybe some could be useful?

"Concerning implementation documentation, I would direct you to the book "Physically Based Rendering" by Pharr and Humphrey, also known as PBRT. I would not suggest implementing the code in there because it is designed to
be easily understandable but is far from optimized, and also, I find the
implementation overly complex."

:lol:
anyone thinking what im thinking? ;)

These are all way over my head, but for what it's worth, the renders are rocking my mind.

Way over my head too, but in general I try :D !

Arbitrarily Layered Micro-Facet Surfaces: It's said "physically correct" by the authors... but layered materials could effectively be simulated in Indigo, if the blend map was based on the angle between camera and shading normal directions (I should be able to give more details if needed). I think the relevant vectors are exposed in ISL for that matter, but I'm not sure. Then multi-layered materials would be possible as well, but I will not pronounce myself about efficiency what so ever.

Distribution-based BRDFs: jackpot !

Last is told "physically plausible", well...

Something else well above my head:

Flat tori in three-dimensional space and convex integration Abstract.

They give more details in french (and pics, for us normal people): http://www2.cnrs.fr/presse/communique/2583.htm
Half way from fractals and ordinary surfaces, the images are those of a smooth fractal. [...] These results open new perspectives in applied mathematics, especially for visualization solutions of differential equations we meet in physics or biology. The amazing properties of smooth fractals could also play a central role in the analysis of geometry shapes.
Here you go with the peasy version.
Ultimately, these products prove to be a key opening the door to the understanding of the paradoxical surfaces thought up by Nash and Kuiper almost sixty years ago.
Woops spoiler !

Very interesting!
I see some similarities with interpolating subdivision schemes (C1 only)

I thought of implicit surfaces but those are C2 I assume.

I have this obsession about Indigo being able to elude geometric angles totally for smoothed shapes :roll:
