Real-World Measurements for Call of Duty: Advanced Warfare

this in-depth document (26 pages) covers how real-world measurement is used to achieve correct lighting in call of duty
explanation of camera concepts
getting relative EV differences between light and shadowed areas is more important than having absolute correct values
how having consistent measurements between the real world and in-game allowed numerous issues to be discovered and fixed
the exposure handling required for the sizeable dynamic range of the scene
how to capture accurate HDR photographs, albedo textures, and specular gloss

an in-depth overview of color, color spaces, and color transformations
discussion of HDR standards
ACES pipeline overview
implementation of HDR pipeline covering
- tone curve, display mapping, UI rendering
- universal CLUT and color grading

look at solution developed by Imageworks compensates for the energy loss in a single bounce BRDF model
improvements to the model

how to generate command buffers in parallel on the CPU
metal can analyze data dependencies to insert GPU parallelization automatically
explicit control is supported but requires explicit opt-in
how to build a GPU driven rendering pipeline using indirect command buffers and argument buffers
look at image blocks, programmable blending, tile shading, persistent thread group memory, custom multi-sample color resolve
lessons learned from bringing Fortnite: Battle Royale to iOS

twitter thread with advice how to learn more advanced graphics programming topics

a tutorial that explains how to clip a polygon based on a list of lines in a pixel shader

looks at different file formats and discusses the difference between formats aimed at the interchange of information or consumption only
