Why won’t anyone stop ICE from masking?

For my holiday break project I’ve been sketching out an idea to help soften the on-ramp for beginners learning D3D12: a header file that (very lightly) wraps the D3D12 API and only exposes the latest/most-useful bits through straightforward function definitions with ImGui-style inline documentation.

While visiting my parents this week I was exposed to something from a distant past called “TV commercials”. I was surprised how many of them were for slot machine phone apps and online casinos. 😕

I finally found the time and energy to make a new blog and write a couple of posts. This time I wrote about PBR content and game development principles. Both posts are quite different so hopefully people find something interesting on either one of them.

For anyone who's tried to use spherical harmonics for lighting and found the notation- and terminology- heavy definitions confusing, highly recommend this classic: grahamhazel.com/blog/2017/12...
I think Graham Hazel's blog was down for a long time, years maybe, but works now!

I've got a new blog post for all of you fine folks! It runs through the additions to D3D12 since it was released, and finishes up with some of the things that have changed for me personally in my code.

I just got a new monitor with a built-in KVM switch, and so far it's a much better experience than my old DisplayPort KVM switch. (Hopefully) no more black screens, missing input, or limited resolution/refresh rates.
