How to use light to make better demos?

This is the third day at Revision, and my contribution this year is the talk I gave yesterday. Unlike last year, this seminar is not technical at all but focused on the design aspect and, to some extent, how it relates to the technical one. The context is demomaking, but many ideas are still valid in other media.

There were some issues with the recording unfortunately, which means some elements are missing (you will notice some blanks at the beginning). In particular after 5mn, there is an important point which was completely cut out. The text was:

Throwing a new technique at whatever you’re doing is not going to make it any better. It’s only going to change what you can achieve. There are two sides of image creation: the technical one and the artistic one. Different techniques allow to do different things, and the more techniques you master, the better you understand what you can and cannot do with them, and how to do it. Technique becomes a tool that changes how you can express yourself.

Here are the slides with notes (~5MB), or a low quality version (~1MB).

FaceWorks demonstration at GTC

Geeks3D mentioned this keynote at the GPU Technology Conference, where NVIDIA’s CEO shows their technology called FaceWorks. After talking about the uncanny valley and avatar rendering uses, came the live demonstration, which seriously raises the bar in terms of face rendering and animation.

The quality is incredible, the gap from photo realism is getting very narrow, and some expressions are really convincing. The transitions and frozen expressions feel weird though, so I am wondering how it would look running freely for a moment, with all the rapid subtle moves we show even when staying idle. The avatar as a mean of communication is certainly very appealing. It would be interesting to see if when facing this rendering, we would react to the expressions displayed.

The demo itself starts after 8 minutes.

Talking about light at Revision, 2

Last year I gave a talk at Revision in which I summed up some of the things I had been gathering on light shading.

This year too I will be attending Revision, in Saarbrücken, Germany, and will give a talk about light again. I will present some of the new stuff I learned. This time the topic is going to be focused on the use of light from a design perspective, in particular in the context of demo-making. It will also be an opportunity to improve on the things I wasn’t happy with regarding the performance: hopefully a better diction, flow and construction.

The talk is scheduled for Saturday, March 30th, at 12:00: “How to use light to make better demos?”. Please come and don’t bring tomatoes. :)

Also make sure to have a look to the complete list of talks, there is a lot of exciting stuff scheduled.

The science gap

I mentioned before the video by cartoonist Jorge Cham, illustrating the explanations of a CERN researcher on the Large Hadron Collider and the Higgs boson. This video was great and explained in layman’s terms the matter (pun intended) of this huge research project.

Today I watched a TEDx talk by Jorge Cham, tackling with what he refers to as the science gap, between the people who do science, and the general public. A part of his talk explains the story behind the Higgs Boson animation, and this story alone makes the talk worth watching.

My top four favourite TED talks

In no particular order, here are four TED talks I keep getting back to, which makes me think they are my four favourites.

TED talk about femto photography

I already mentioned the camera built by a team in the MIT Media Lab, allowing with its trillions of frame per second, to capture the propagation of light or to see around corners.

TED published a video of the talk given by Ramesh Raskar, where he presents this work and the new possibilities it opens.
