Someone suggested this post from Bart Wronski, which is exactly what im asking about.
Other sources doing similar still welcomed. The more the merrier if there are any others! :)

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.

A former French military base, Vauban is a thriving neighbourhood of 5,500 residents connected to Freiburg town centre by bus and light rail. Built in the late 1990s as a radical experiment in low-car living, it forgoes virtually all on-street parking in favour of active, green, and social spaces. 🧵

Here's Bolt3D: fast feed-forward 3D generation from one or many input images. Diffusion means that generated scenes contain lots of interesting structure in unobserved regions. ~6 seconds to generate, renders in real time.

I just pushed a new paper to arXiv. I realized that a lot of my previous work on robust losses and nerf-y things was dancing around something simpler: a slight tweak to the classic Box-Cox power transform that makes it much more useful and stable. It's this f(x, λ) here:

After many years of giving talks, I no longer get nervous.
Instead, I'm now nervous when my students give talks!
Fortunately, they do an amazing job.
