I've found this cute approximation for arctan(x). I'm not suggesting you should use it, all I'm saying is it's cute.

Demo of bilinear interpolation of SDF samples:
- Negative (interior) samples of the analytic SDF are blue, positive (exterior) samples are orange.
- Circles are drawn around samples to show distance magnitude.
- Intermediate bilinear interp samples / segments are drawn.

I'm excited to share our latest paper (work with Matt Pharr and @inversepixel ), "Improved Stochastic Texture Filtering Through Sample Reuse" accepted to I3D'2025.

Published a WIP 'dynamic_fonts' branch to receive feedback. This should evolve and stabilize toward a 1.92 release (in 1-2 months): github.com/ocornut/imgui/iss…
(Published code in this branch includes font scaling but not style/general scaling yet. Still working on that)

Daniel Tapia shared a cool experimental mechanic in his UE5-powered sandbox racing game Carbox, where the city builds itself right before the driver's eyes.

I wrote a blog post on my implementation of the Surfel maintenance pipeline from my Surfel Radiance Cascades project. Most of what I learned came from "SIGGRAPH 2021: Global Illumination Based on Surfels" a great presentation from EA SEED :)

I'm very happy to announce that our paper "Don't Splat your Gaussians: Volumetric Primitives for Rendering Scattering and Emissive Media" (tinyurl.com/GaussVol) was finally accepted to ACM Transactions on Graphics last month! We will present it at SIGGRAPH 2025

Started my own version of the Dragon ball sparkling zero super speed effect.
I think they used a separate mesh for it, but I am doing it differently. I'll keep adding to it!

"Deep and Fast Approximate OIT" performs one geometry pass to extract 4 per pixel features from the transparent scene and a screen space pass to feed them into an 2 hidden layer MLP to calculate the approximate OIT colour: onlinelibrary.wiley.com/doi/… shaders github.com/gtsopus/DFA
