TdrLevel: LOCK_UP_MY_SYSTEM_PLEASE

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’m no EA apologist but I’m not sure if they deserve the full blame for that…by at least some accounts it sounds like the the team had some fundamental issues that they were unable to resolve. www.designer-notes.com/spore-my-vie...

Spore: My View of the Elephant

A few weeks ago and with little fanfare, Spore turned five-years-old. The game was announced at GDC 2005 during Will Wright’s annual mind-blowing speech on whatever floats through his head. The ini…

There’s this, but not exactly the same: shadered.org/template

Pick a starting point - SHADERed

SHADERed is the most powerful shader IDE/editor. It is open-source, cross-platform & has features such as the shader debugger, compute shaders, plugin API, etc...

That SFINAE stuff sure looks like a compile-time killer 😬

mjp @mjp123.bsky.social · 28d

Yeah it’s from the Steam HW survey, which is useful but also imperfect and misleading in many ways. They put a disclaimer when on the “Can I Use This?” page: d3d12infodb.boolka.dev/CanIUse.html...

Yeah that table would be a lot bigger for Vulkan, wouldn’t it? 😅

mjp @mjp123.bsky.social · 28d

It would be nice if the Vulkan DB had something like this, which is awesome for seeing which features a GPU family supports: d3d12infodb.boolka.dev/FeatureTable...

Yeah the Vulkan hw database is a bit tough to use for the purposes of knowing what your target hardware supports as a baseline. You can filter your the last year of reports though which changes the stats. Looks like on Windows the reports without support are mostly old AMD:

How do you sit for an hour with that?

mjp @mjp123.bsky.social · Sep 8

Yeah it wouldn’t be very much fun to restrict yourself to the base interface versions and fxc 😄

mjp @mjp123.bsky.social · Sep 8

Thank you Nico, I was indeed imprecise in how I described that. I’ll update it. 🙂

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 👴).

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...

Even if there are actually entry-level positions for human junior programmers, they still need to make it through the gauntlet of AI-powered resume screening. It’s pretty bleak, job rates and enrollment are both down for CS majors.

mjp @mjp123.bsky.social · Sep 2

Can’t comment on switch, but I think you’re good on that otherwise as long as you ignore PC GPUs from before 2015 🙂

This article popped up in my Apple News feed, and I did a double-take when I saw the head render. My skin/SSS people will know what I’m talking about. 😄

Some fun with shader-based debug drawing: here I'm drawing an arrow for each path taken in the path tracer, starting with the pixel under the mouse cursor.

Out of curiosity, what do you like about it?

…but too much! Let’s not get crazy.

mjp @mjp123.bsky.social · Aug 21

Like the “enhanced” compile times? 😅

mjp @mjp123.bsky.social · Aug 21

We still don’t have it on, no designated inits for me yet

Dumber AI for dumber people! What could go wrong.
