Senior Graphics Engineer @ LunarG, musician, deeply in love with science, arts and literature.
We submitted the final chapter of the 2nd edition of Mastering Graphics Programming with Vulkan! We rewrote and expanded much of the book, exploring TAA upscaling, ray-traced shadows, reflections, GI, denoising, mesh shaders, and modern Vulkan. Now time to review everything! :)
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...

I’m looking forward to speaking at GodotCon in Amsterdam this Friday. I’ll be giving “Integrating Vulkan Ray Tracing in Godot” again — same presented at Vulkanised, but for a Godot-focused audience. If you’ll be there, come say hi. conference.godotengine.org/2026/ #Godot #Vulkan #RayTracing

If you wanna know if #Vulkan @vulkan.org is the right graphics api for hobby developers (tl;dr: yes), you might find an answer in my #Vulkanised 2026 talk: www.youtube.com/watch?v=Eshk...

The recording of my Vulkanised 2026 talk is now live 🎥 In this talk, I walk through the journey of bringing a Vulkan RT pipeline into Godot. www.youtube.com/watch?v=HddS... Thanks to LunarG for the opportunity and to the @godotengine.org community for the reviews and feedback.

The 2026 Global Game Jam #GGJ26 was last weekend, so let's take a look at their historical data for engine usage. 📈 @godotengine.org is having a good run! #Godot is now firmly established as the #2 engine in game jams (correlated by #GMTKJam data), rapidly closing the gap with #Unity.
It took me 1 month to make this video. It's 43 minutes and it's jam packed with cool information about how I make PS1 games and how I made Yume Nikki PS. www.youtube.com/watch?v=dsA2... #gamedev #indiedev #psx #ps1 #yumenikki
I made a real PS1 game in 1.5 months

My PR for a Vulkan Ray Tracing pipeline has been merged into Godot! I’m grateful to everyone in the community who took the time to review. github.com/godotengine/... Want to know more? I'll be talking about that at Vulkanised 2026 in San Diego on Tuesday, Feb 10, 2026! vulkan.org/events/vulka...

a reminder that I'm still looking for work if anyone needs an engineer specialized in UI and 3D/graphics 👀 I did some pretty amazing (NDA) stuff at PlayStation, and my personal open source work is forward thinking too 🧠🔮✨

Godot GDScript ambient occlusion demo accelerated with the Vulkan raytracing pipeline. Fun has just begun!
I figured it out! Godot compresses some geometries when importing Sponza, so some positions are packed into rgba16. I am not sure whether Vulkan acceleration structure building supports that so, sorry, do not compress please.
Antonio Caggiano@antoniocaggiano.eu · 2y agoImproving my #Godot GDScript #Vulkan raytracing demo, I finally managed to fix some validation errors and visualize normals properly. Some geometries are missing though. 🤔
A collage of different test scenes I used in my raytracer. Gotta admit I'm quite happy with it 🥰
The tinybvh sample wavefront path tracer now supports specular materials. :) Never stops being amazing, just look at those caustics on the floor that appeared out of nowhere. Path tracing is such a cool toy.

I'm late for ~7 months, but I've finally published my C++ & WebGPU raytracer on GitHub! I've tried to keep the code fairly commented and readable. It works pretty well, but I've never managed to make refractions work with VNDF. Maybe another time :) github.com/lisyarus/web...
