GDC 2015 presentations

The Game Developers Conference took place last week in San Francisco. As I am starting to see more speakers publish their slides, I am creating this post to keep track of some them (this list is not meant to be exhaustive).

For a more extensive list, Cédric Guillemet has been garnering links to GDC 2015 papers on his blog.

An artificial light that looks like light from the sky

http://www.coelux.com/

The Italian company CoeLux has apparently managed to create an artificial light which uses a material that mimics the atmospheric scattering, to look like sunlight and light from the sky. Judging from the photos and videos available on their website, it seems the look is very convincing.

As they point out, this could have a serious impact on architecture, as available sunlight is a factor in the design of buildings. Unfortunately, at this stage it is a prohibitively expensive product for the average consumer, and likely targeted at the construction industry. But it might be only a niche for some years before expanding to a larger scale.

The news websites PetaPixel and Colossal have previously covered this topic last month, and included some larger product photos made available by the company. But the most interesting coverage might be the one by Lux Review, who met CoeLux at an exhibition booth and made the following video. From their article:

No, the light source doesn’t move… yet. No, the colour temperature isn’t dynamic… yet. The void height needed is a metre. It consumes 340W of electrical power, but that will come down as LEDs improve.

John Carmack on Oculus at GDC 2015

John Carmack, the CTO of Oculus VR, gave a talk at the Game Developers Conference that just ended this week. Various topics are addressed, including the story behind Samsung’s Gear VR and what’s coming next, the democratization of virtual reality, the work on the API, the unsolved problem of controllers in VR, or the use of real-time ray tracing in VR.

John Carmack’s GDC 2015 talk.

It is a fairly long video (1h30), and as often with him, there are no pictures to see, just hear his personal views and insights on the work he is currently taking care of.

The Rescued film project

The Rescued film project aims at developing and archiving film rolls that, for some reason, were left undeveloped. In this video they present their work, and more specifically when they discovered 31 rolls shot my an American from WWII soldier.

The photos can be seen on their website.

Insight In An Unseizable World, by Cocoon

Last Fall, the French demogroup Cocoon uncovered this beautiful ambient demo: Insight In An Unseizable World. Its technical features, including real-time fluid dynamics or screen space reflections, manage to stay humble a leave the full stage to the superb direction. The special attention given to transition is outstanding, and I invite you to see by yourselves.

Intrinsic Gravity, by Still

Three years ago, the German demoscene group, Still, was releasing an experiment at shaping some of the work of late painter Victor Vasarely as animated figures in a tribute demo: Beta. The unusual style from a demoscene standpoint, extrapolating what his work would have been if it were animated, was a success.

Last week Still released another demo with a similar geometric style and a brilliant direction: Intrinsic Gravity. It serves as an invitation to the demoparty NVScene, to take place in San Jose, California, this March.

I recommend you these two demos, they are a pleasure to watch.
