Found a bug in the radiance caching code snippet published on my blog so went and ahead and corrected it:) (explanations and visualisations in replies 👇)
Here’s the article in question: gboisse.github.io/posts/this…

"Practical Unbounded Hash-Grid Encoding for Neural Radiance Caching" is out in GPU Zen 4. It is mostly about things in NRC not written in academic papers. Hope this is an intro of ML to graphics people (like us).

Capsaicin is not just for tacos, it's also our developer rendering framework!
v1.3 is out now:
🌶️ Added heat with GI-1.2, which includes multiple-bounce indirect lighting.
🌶️ HDR support with spicier tone mapping.
And much, much more: gpuopen.com/learn/gi-1-2-mul…

Radix Sort is a fast, non-comparison-based algorithm ideal for sorting large datasets especially on GPUs.
💡 Check out our research that introduces a memory-efficient GPU Radix Sort that improves on Onesweep:
