HDR Display in Call of Duty

In 2018 I did a presentation for Digital Dragons in Kraków on HDR Display in Call of Duty.

This is a collection of the presentation materials and various related resources.

You can download the slides from the Activision Research Site.

Shadertoy

As I’m slightly obsessed with Shadertoy, I used Shadertoy for some of the diagrams in the presentation. I learned a lot from doing this and some of them may be useful as reference.
