Analyzing Modern NVIDIA GPU cores PAPER: arxiv.org/abs/2503.20481 Reverse engineers NVIDIA GPU cores, detailing issue logic, register caching, memory pipelines, and hardware-compiler interaction. Integrates findings into a simulator with 13.98% MAPE on RTX A6000—outperforming

Updated my MIS blog article with some more details on how Veach defines a one-sample estimator in his '97 thesis and how it relates to the rest of the article: lisyarus.github.io/blog/posts/mul…

Here is a new blog post of mine, where I dive deep into the theory and math behind ReSTIR GI. Big thanks to Markus Kettunen for verifying the theory, reviewing the article, and catching a key detail I had missed. agraphicsguynotes.com/posts/understa…

For their 20th anniversary, Evermotion has a new free insanely detailed 3D scene available for download, including both an exterior forest and a house with full interior. What an amazing resource! evermotion.org/shop/show_prod…

BVH Quality: Beyond SBVH – Jacco’s Blog jacco.ompf2.com/2025/05/20/bvh…

Tried DLSS RR in my path tracer and it's pure magic. I think it's quite expensive for games (~7ms for this image on laptop 3080), but for previz in path tracing it's really good, very resposive and high quality

Neural Visibility Cache for Real-Time Light Sampling boksajak.github.io/files/NVC_pape…

Implemented BSDF evaluation and PDF query for microfacet-based normal mapping to support more light transport algorithms. For dielectrics, I need to make some adjustments to the equations in the original paper. Now I need to find a beautiful scene and test it.😉

Worth watching presentation, also provides some background info on how ReSTIR came to be and where it is heading: "ReSTIR: Traveling the Path of Reuse" youtube.com/watch?v=MRg91Z…

Curious to know how many cycles each CPU instruction costs? The instruction matrix from Google's highway (a cross-platform SIMD library) has interesting details. github.com/google/highway…
