I made a 32.32 fixed point math library with @PetriKero (targeting 64bit cpu archs). Most relevant math ops should be there. C# and C++, so #unity3d games can be made deterministic across platforms now. :) github.com/XMunkki/FixPoi…

Enterprise PBR Shading Model v2025: dassaultsystemes-technology.github.io/EnterprisePBRS…

It's been over 10 years since we released Rogue Legacy 1, and in the pursuit of sharing knowledge, we are officially releasing the source code to the public. github.com/flibitijibibo/… Eternal thanks to @flibitijibibo for setting this up, and being with us since the beginning.

"GPU Programming Primitives" Siggraph Asia 2023 course, discussing GPU implementations of tech like parallel reduction, radix sort, spinlock etc. Good optimisation section focusing on memory coalescing, groupshared mem bank conflicts and shader occupancy. gpu-primitives-course.github.io

Signed distance functions (SDFs) are an important surface representation, which can be directly visualized via the “sphere tracing” algorithm. At #SIGGRAPH2024 we showed how to sphere trace a whole new class of surfaces, based on *harmonic functions* rather than SDFs. [1/n]

Great article if you want to understand the differences of mobile and desktop GPUs. chipsandcheese.com/2024/07/04/the… The most important tidbits are 4x lower mem load issue rate (L1$ bandwith) and L1$ only serves textures. Buffer loads hit L2$. Big impact in GPU-driven / V-buffer.

enjoying #ICML2024 ? already finished with llama-3.1 tech report? if so, you must be concerned about the emptiness you'll feel on your flight back home in a couple of days. do not worry! Wanmo and i have a new textbook on linear algebra for you to read, enjoy and cry on your long flight. (1/5)

I've spent the past ~3 weeks going through the entire history of deep learning and reimplementing all the core breakthroughs. It has completely changed my beliefs about deep learning progress and where we're headed. Progress tracker in thread (all resources at the end) 👇

In our latest @I3DCONF paper, we transform any rasterizer into a differentiable one with minimal engineering and zero external dependencies. Optimize game assets and volumes, train 3D Gaussian Splats, etc. directly within your existing engine. Compute shaders is all you need!

NVIDIA just released FREE online courses in AI. Here are 9 courses you can't afford to miss:

I wanted to work it out once and for all framerate-independent lerp smoothing 🐱

The course notes from "A Gentle Introduction to ReSTIR" are not only well written but well presented as well, I really like the right column with the references and notes, so much easier to use compared to scrolling to the end of the document and back. intro-to-restir.cwyman.org 1/2

I've updated my open source BRDF implementation (brdf.h) to v 1.2 - adding new VNDF sampling using spherical caps by Dupuy & Benyoub, reflectance parameter and more improvements. Grab it on GitHub here: github.com/boksajak/brdf. Original blog post is here: boksajak.github.io/blog/BRDF

I put up the pre-print of our LDAV '23 paper on speculative, progressive isosurface raycasting: willusher.io/publications/w… ! We interactively render isosurfaces of volumes up to 2k^3 entirely in the browser on the GPU using #WebGPU ! Try out the live demo: willusher.io/webgpu-prog-is…

The ultimate comparison of Hierarchical LOD graph performance rendered with CS and HW rasterization on desktop and mobile GPUs, including WebGPU, shows that algorithmic flexibility is much faster than any HW FFP: tellusim.com/04_hello_raste…

Somehow missed this awesome talk by @SebAaltonen about rendering SDFs in games (used in Claybook): youtu.be/Xpf7Ua3UqOA Check it out if this sort of thing interests you.

Volumetric lights with transparent shadow maps, read below how they are rendered:

"BRR: A new line drawing method for the cycle savvy" 🔗quiss.org/boo/

Now that the latest Chrome version has WebGPU support I guess I can finally talk about this. A year ago @david_ar and @cornusammonis were developing a compute shader based Shadertoy alternative called compute.toys I already had a lot of fun making some toy projects 😳
