Computing the exact bijection of the optimal transport (OT) problem between very large point sets is completely untractable… In our SIGGRAPH Asia 2025 paper: “BSP-OT: Sparse transport plans between discrete measures in log-linear time” we get one with typically 1% of error in a few seconds on CPU!

Happy to announce: ReSWD. Sliced Wasserstein Distances are quite powerful, but they perform a Monte Carlo (MC) integration (over random directions). During an optimization this can lead to noisy gradients due to variance. Project page: reservoirswd.github.io

A little something I've been meaning to write for a while martinfullerblog.wordpress.com/2025/09/26/a... Thank you to the awesome people at Machine Games and id Software!

✨ Am I the only one absolutely obsessed with the watercolor FX our team just pulled off? 🎨🔥 Every frame feels like a living painting and I can’t stop staring at it 😍 #GameDev #IndieDev #PaperCastle #VFX

Continuing on the topic of GPU utilisation and performance, as a practical example, I looked a bit deeper into the impact of vertex shader exports on the cost of a drawcall and wrote another blog post with some observations interplayoflight.wordpress.com/2025/09/21/t...

Fantastic, interactive article about realtime blur algorithms by FrostKiwi! blog.frost.kiwi/dual-kawase/

Every lens leaves a blur signature—a hidden fingerprint in every photo. In our new #TPAMI paper, we show how to learn it fast (5 mins of capture!) with Lens Blur Fields ✨ With it, we can tell apart ‘identical’ phones by their optics, deblur images, and render realistic blurs.

A recap for the Bluesky crowd: my implementation was largely based on DDGI, which uses software raytracing to sample light into a grid of probes. I implemented multiple cascades, moving grids & dynamic probe states. It allowed for infinite bounces & (potentially) infinite environments.

wave_tracer 0.1 released wavetracer.dev wave_tracer combines path tracing and wave optics in a novel way, for practical general-purpose wave simulations across a variety of EM modalities and applications.

I made a configurable multi-plot utility Shadertoy www.shadertoy.com/view/WclyzB For the erosion video I'm working on, I want to show some function graph synced with erosion parameter changes. I wasn't happy with the existing function plotting examples I could find, so made my own here.
