Talking about light at Revision

Over the last months I have been reading various resources on light shading, and shared the most relevant ones on this blog. Along the way I became more and more thrilled by how light interacts with materials and how we can model it to get more convincing rendering.

I found some insights to be really enlightening and very worth sharing. Therefore as a way of challenging my own understanding of this matter and as an opportunity to practice talk, I decided to speak about real-time lighting during a seminar at Revision.

Revision is a big demoparty that will be held during four days over the Easter weekend in Saarbrücken, Germany. If you are coming (which I recommend) and want to hear about shading, specular and Fresnel, come and see me!

Update: the talk is scheduled for Saturday April 7th, 14h – 15h.

“Introduction to light shading for real-time rendering”

Update: see this post for the material.

Mesh generation in Farbrausch demos

Back in 2007, the German demogroup Farbrausch was releasing its masterpiece, fr-041 Debris. Aside from the artistic qualities of this demo, it is impressive by its size: just 177kB worth of binary, for a seven minutes long full featured animation. The equivalent of a mere ten seconds of mp3 of poor quality. Size coding at work.

Reaching such a result requires dedicated tools, compression of course, but more importantly, content generation. Fabian Giesen offered in a recent blog post to give some details of the techniques used for this demo. After a quick poll, he decided to start with mesh generation, hence the first post of a very promising series: Half-edge based mesh representations: theory.

Solarized environment

During last year I tested and adopted two tools for my environment: the Anonymous Pro font and the Solarized color palette. After months of use, there is no way back: the difference of comfort is significant, and any text application allowing to be configured so gets them on my work stations.

Solarized has a repository of configuration files for various applications. Unfortunately those are made by different people, with different tastes, and thus the color choices are not consistent from one application to another. This means you may still have to go through a good deal of tweaking if this is annoying to you.

Paths of Hate

Paths of Hate is one of the many animations that were shown at the Computer Animation Festival at SIGGRAPH 2011, and among the ones that drew most attention (it was awarded the Jury Award). Directed by Damian Nenow, the film explores in a comic style how deep hatred can go. Unfortunately I haven’t found the long version on Internet, only the following trailer. If you have the opportunity to see the full version, do not miss it.

State of the art in real-time realistic skin rendering

Jorge Jimenez posted yesterday the last results of his research on skin rendering: Separable Subsurface Scattering. He provides a very impressive real-time demo, which, some point out, does runs on actual current hardware (it ran, slowly, on my low-end laptop). So even though he provides the following video of it, you should definitely try the actual binary. Oh, and the source code is available too. :-)
