SIGGRAPH 2013

Posted on 2013-05-22 by Julien Guertault

More and more material and news are being released about the next edition of SIGGRAPH, so here is a short summary.

Technical papers

The video teaser of the technical papers has been published. It looks like there will be some really cool stuff to see. As every year Ke-Sen Huang maintains a page with the list of papers.

Real Time Live!

The Real Time Live! program looks very nice too, and it is good to see at least two demoscene related works will be presented there (the community GLSL tool ShaderToy by Beautypi, and some experiment by Still with a LEAP Motion controller on their production, Square).

Courses

Not much to say, it looks great and I want to see most of them… The Advances in Real-Time Rendering in Games and Physically Based Shading in Theory and Practice courses are a must see as usual. The Recent Advances in Light-Transport Simulation: Theory & Practice and Ray Tracing is the Future and Ever Will Be courses sound promising too.

Our work to be shown at SIGGRAPH

Lastly, we had some awesome news yesterday, when we were told our last released demoscene production, F – Felix’s workshop, has been selected to be shown as part of the Real-Time Live! demoscene reel event.

Released last year at Revision and ranking 2nd in its category, Felix’s workshop is a 64k intro: a real-time animation fitting entirely (music, meshes, textures…) within a 64kB binary file meant to run on a consumer level PC with a vanilla Windows and up to date drivers.

I was also told Eddie Lee‘s work, Artifacts, was selected as well. His outstanding demo won at Tokyo Demo Fest earlier this year.

Making the subtle obvious, follow-up

A couple of months ago I was posting here about this SIGGRAPH publication on amplification of details in a video. Yesterday the New York Times put online a story as well as a video on the topic, with explanations from the authors and some new examples.

Making the subtle obvious

Take a video, decompose it into several frequency components, filter and amplify each one, recompose them back to an output video, profit. Nuit-Blanche mentioned this paper presented earlier this year at SIGGRAPH. I never thought you could actually detect the blood flow from a simple video…

Update: more to see in this follow-up post.

Short reading list on diffuse lighting

Posted on 2012-10-09 by Julien Guertault

This is going to be a short one: I haven’t done any extensive search, but I still want to make a back of the envelope note with a couple of links.

M. Oren and S. K. Nayar proposed a model more accurate than the Lambert reflectance in their paper: Generalization of Lambert’s Reflectance Model, referred to as the Oren-Nayar model
Pope Kim has an article presenting the Oren-Nayar approximation they used for their game at Relic (slides of the full talk: The Rendering Tech of Space Marine).
At the SIGGRAPH 2012 course, Practical Physically Based Shading in Film and Game Production, Yoshiharu Gotanda presented the shading model developed at Tri-Ace (slides and course notes), including their Oren-Nayar approximation.

SIGGRAPH 2012 links

I wanted to put here a couple of links on SIGGRAPH 2012 material, but as the Real-Time Rendering blog points out, somebody has already made a comprehensive list of what can be found. So wait no more, go there and pick up your commuting time reading for the next weeks: SIGGRAPH 2012 Links.

The Fantastic Flying Books of Mr. Morris Lessmore

Another memorable film of the Computer Animation Festival of SIGGRAPH 2011 is the Best of Show Winner: The Fantastic Flying Books of Mr. Morris Lessmore, a beautiful tale about books and their legacy by Moonbot studios.
