Ten Years of D3D12 For those of us that have been using it from the start, it can be hard to believe that Direct3D 12 has been around for nearly ten years now. Windows 10 was released on July 29th 2015, and D3D12 has be...

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.

(And yes it's really been 10 years ๐Ÿ‘ด).

Judging from the lineup and responses, this year is going to be even more amazing than last year's - can't wait!

Honestly, forget about AI tools. The trifecta of power tools for game engine development is RenderDoc, Superluminal and Live++. Hands down the most bang for your buck you can ever get and RenderDoc in particular is criminally underpriced.

D3D12 Resource States Cheat Sheet - Dangling Pointers D3D12 Resource States rules are complicated, especially around state promotion and decay, but this article is helpful summary.

I wrote a blog article about D3D12 resource states.

It explains the rules around state promotion/decay and how that means a resource can be used on multiple queues at the same time (even if one queue is writing!)

I have another take on โ€œVibe Codingโ€, and it doesnโ€™t involve gen AI:

Spend time coding on a project you enjoy, following a coding methodology and style that reflects you, experimenting on things you like, without overbearing process.

That, is vibe.

I'm almost done writing my STL replacement, or at least I have enough to replace almost all std:: uses in Asset Cooker.

All that's missing is Mutex, Semaphore and some specific Atomic specializations for pointers/enums. A few evenings of work?

After that I guess I'll make the github repo public ๐Ÿ˜ถโ€๐ŸŒซ๏ธ

RESTIR is one of those moments in computer graphics where a method is too useful to ignore, but too complex to fit in a textbook paragraph - and with time, the explanation simplifies and it becomes canon. This course by Chris Wyman is a huge effort to explain and simplify
