Joined June 2008
After some late night coding nights I finally released px_render.h Single Header backend renderer (multithreaded, command based, render agnostic) github.com/pplux/px Heavily inspired by bgfx (@bkaradzic) and sokol_gfx (@FlohOfWoe )

Remesher has an online demo; I use it for development and testing so I haven't spent much time on polish :) This is remesh → simplify → unwrap → retexture from release notes, unwrapping powered by xatlas and retexture powered by three-mesh-bvh ❤️ meshoptimizer.org/demo/remes… 2/2

To all my friends at Mediatonic, I’m extremely heartbroken and overwhelmed by the news. At 2K we’re currently hiring for some roles so please DM me. (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

Valve artist @rich_lord gave a great talk at SIGGRAPH HIVE 2023 that every rendering dev should watch. Tons of inspirational moments for shader development. The fractal sequence starting 29 minutes in is impressive. youtu.be/R-S9d-qFRHM?si=JvoE…

Simplified explanation of gaussian splatting for gfx engineers: You render all surfaces as stretched alpha blended point sprites. Sprites have gaussian blurred sphere texture. No triangles, just could of point sprites. It's like the old demoscene approach on steroids :)
NeRFs had a good run. But 3DGS (Gaussian Splatting) now beats them in most respects: - higher quality - faster training - real-time renderable - initializable from SfM - easier to understand/implement - composable w. traditional pipelines - smaller, interpretable representation

Epic Games Store launched in 2018 with an 88% / 12% revenue split. Now developers can also choose a new option: launch your PC game on EGS first for 6 months for a 100% / 0% revenue split. Devs earn more money, Epic reaches new customers, everyone wins. theverge.com/2023/8/23/23843…

Another shadertoy thing: how to use shader derivatives to draw fixed-width lines using 2D curve equations as an example. shadertoy.com/view/mlXBRr

Finally, I'm rendering an SDF scene with splats for the first time. The shader that I used to voxelize is now generating a list of splats containing world positions, colors, and normals. A splats counter is increased and later used in a draw indirect call. #OpenGL #Graphics #GFX

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_raster…

NVIDIA finally released Neuralangelo's source code! The model can turn videos from any device into detailed 3D structures, fully replicating buildings, sculptures, or other real aworld objects or spaces virtually. Here's how it works: A model utilizes a 2D video with multiple angles of an object or scene. I selects frames from different viewpoints to understand depth, size, and shape. The AI creates an initial 3D representation, similar to a sculptor shaping a subject. The render is optimized to enhance details, like a sculptor refining texture. The outcome is a 3D object or scene suitable for virtual reality, digital twins, or robotics.
