what if I just post a neat little luxe thing every day/hour/whatever #createwithluxe #gamedev (after having been offline for ages for a variety of reasons)

Herautober day 15 ! Two weeks already... #Soulframe #EnvoyCreate #Envoy #Tennocreate #soulframefanart #Envoytober #herautober

We're happy to announce #RhizomeAudio, a new audio engine for real-time audio. Please check it out at rhizome.audio. We're here at #GameSoundCon showing it off so please stop by the booth in the expo for demos and a chance to try it out yourself. #ProceduralMusic #GameAudio

Day 7 of Herautober ! #Soulframe #EnvoyCreate #Envoy #Tennocreate #soulframefanart #Envoytober #herautober

New blog post! In "Billions of triangles redux" we take another stab at improving various parts of clustered level of detail pipeline to make Zorah smaller and nicer! zeux.io/2026/09/30/b...

"Unroll a loop, make shader 10x faster", where I accidentally speed up Blender's Kuwahara compositor node on Apple GPUs (and elsewhere). aras-p.info/blog/2026/10...

the revive shrine~ hi digital extremes, i like your game a normal amount #soulframe #soulframefanart #art #driftcreates #envoycreate

Emissive shaders. Type a temperature in K and get a blackbody colour – that's how most shaders do it, and it's wrong for practically every real material. Kirchhoff's law fixes it. www.linkedin.com/pulse/therma...

DASHR - Dynamically Animated Skinned Heightfield Rendering Short video for now - I might do a longer one later? youtu.be/-Su9YrcazRk But there's ALL the details in the paper, and you can always Use The Source, Luke for the really deep info. github.com/tomforsyth10...

meshoptimizer 1.3 is out! Featuring a new voxel remesher, support for normal generation, several simplification improvements and various optimizations and fixes. GitHub stars and reposts appreciated! meshoptimizer was started 10 years ago; excited for the years to come! github.com/zeux/meshopt...

They let me make a puppy simulator!!!!!! I cannot undersell you how excited I have been working on this and how long I have spent prototyping this system.

In ~2007 when coding the ambient lighting of Splinter Cell, I had the idea of storing dynamic SH probes in Voronoi cells, where a) dynamic objects could walk/lerp the face graph, and b) static meshes "palettised" probes per vertex and lerped to give Realtime GI. It never shipped but look how pretty!

New Fable gameplay demo. Very proud to be part of this super-talented team! I hope you'll enjoy it: www.youtube.com/watch?v=bjso...

WIP spec for Work Lists, the successor to ExecuteIndirect that lets you change PSOs between draws and dispatches github.com/microsoft/Di...

Slides for SIGGRAPH 2026 Advances in Real-Time Rendering in Games course's talk on Variable Rate Ray Tracing in Call of Duty: Modern Warfare 4 by Michał Olejnik from Activision are now online - enjoy!! advances.realtimerendering.com/s2026/index....

It's great to see ARM being so open about their neural joint denoising and upsampling, explaining their approach, network inputs, temporal stability and how they trained this network: community.arm.com/cfs-file/__k...

Really cool, a post of mine made it into an industry presentation! :D "The Path to Achieving 120 FPS in Ninja Gaiden 4" at CEDEC

Slides for SIGGRAPH 2026 Advances in Real-Time Rendering in Games course's talk on SMOLDER — REAL-TIME VOLUMETRIC EFFECT RENDERING IN GLACIER AND 007 FIRST LIGHT by @lexdev.net from IO Interactive are now online - enjoy!! advances.realtimerendering.com/s2026/index....

A Texture Lookup Approach to Bézier Curve Evaluation on the GPU jcgt.org/published/00... New published paper! The premise is that you can offload polynomial evaluation to the texture sampling unit, which can be useful for improving execution times if you are compute bound.

Bayor's Burden I'm so excited for the @soulframe.com Fall Update! #Soulframe #SoulframeFanart

Happy to share that I'll be joining the Advances in Real-Time Rendering in Games course at Siggraph next week to talk about how we render volumetric effects in our Glacier engine & 007 First Light with Smolder! Take a look at all the cool presentations that are lined up!

2026 Advances in Real-Time Rendering in Games course line up is here - check it out! advances.realtimerendering.com

4K/non-live versions are up now! Soulframe: www.youtube.com/watch?v=wNQe... Warframe: www.youtube.com/watch?v=pKsQ... Both dripping with atmosphere :D

‘Soulframe’ Just May Be The Game We Need Right Now – Even In Pre-Alpha

Here are some of the fun and interesting things I've done that might be lesser known. 👻

Sooooon

What To Learn To Be A Real Time graphics Programmer blog.demofox.org/2026/07/01/w... I wrote this up over lunch and it's surprisingly popular so sharing over here too.

I’m happy to announce the release of a new open source 3D physics engine called Box3D. I’ve been working on this project for a few years now, but it represents over 20 years of experience writing physics engines for games. Read more here: box2d.org/posts/2026/0...

OK so I've seen a couple questions/comments related to whether or not this technique supports *rotation*, which tells me I perhaps didn't do a good job explaining a couple key points. The technique explains how to do an unweighted glyph box filters in a shader...

I've been working on a Kotlin/Compose Multiplatform to interpolate sRGB colors as mixtures of paints/pigments. It can produce results that are more appealing than the traditional sRGB interpolation that Composes uses (see screenshot). Not quite ready for release yet. github.com/romainguy/vi...

new grass tech out today, instancing goes brrrrr, draw distance extended accordingly

Super super excited to finally show what I’ve been working on at SMS blog.playstation.com/2026/06/02/f...

The Cost of AI alextardif.com/AI.html

About 3.5 years ago I did some experiment to improve the behavior of microfacet normals at glancing angles. Many surfaces become highly reflective even though having high roughness. Check the discussion in the thread. Here is my implementation reusing equations you already have:

It's just so good though ahhhhh www.youtube.com/watch?v=ANEV...
