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.

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.

Developing for the Oculus VR

In January, Oculus shared a list of recommendations for a good VR experience as a PDF, and kept updating them since then: Oculus VR Best Practices Guide.

More recently, Tom Forsyth gave a talk at GDC 2014 where he gave some guidelines on what to do, what not to do, and what they haven’t figured yet about making VR experiences. The talk is available in the GDC Vault: Developing VR Experiences with the Oculus Rift.

Update:

Michael Abrash of Valve gave a talk about the near future of VR: What VR could, should and almost certainly will be within two years. Much of it deals with the notion of “presence”, the sensation of actually being in the virtual world, and what makes or breaks it.

Quaternion are a very useful tool in 3D, but also one that is unintuitive and difficult to get a natural feeling about. The talk Jim Van Verth, of EssentialMath, gave earlier at GDC2013 explains some facts about quaternions and how they work, by looking back at their discovery: Understand Quaternions.

Update: on a side note, here is a trick for faster quaternion – vector multiplication.
