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).
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.
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.
