Check out my HPG 2018 Paper, "Deferred Adaptive Compute Shading"! It's a drop-in replacement for checkerboard rendering that typically gives 3–5⨯ better quality/perf and is actually *easier* to implement! Gain is actually *larger* with harder shading! geometrian.com/research/index…

I (re)invented a faster SSE cross-product implementation. What's weird is that fused-multiply-add instructions don't help—and actually seem to *hurt*—performance? Maybe not true when `inline`d, or on newer than Haswell? See my code and analysis here: geometrian.com/programming/tu…

Thanks everyone for a great HPG & SIGGRAPH 2018! I think I am finally caught up on everything, so if I've missed you feel free to ping again. In-particular, if you have questions about Deferred Adaptive Compute Shading, email me! We'd love to see production-ready implementations!

I made a distribution pathtracer in WebGL. • Runs on your phone • Dynamic light / camera • Raytraced reflections and refractions • Indirect illumination • Realtime convergence (no denoising) Yes, I am cheating. geometrian.com/programming/we…

Spreading the raytracing religion! 👁️ ☀️ ↘️ ↗️ 🫖 (My square at the Forest Grove sidewalk chalk art festival last weekend. Yes; I am *absolutely* dorky enough to make over-the-top pathtracing propaganda.)

I made holographic chocolate! Way easier than I thought - and it’s 100% pure bittersweet, no coatings. When you catch the light at the right angle, it’s mesmerizing.

I don't really do the social media thing very much anymore, and I don't anticipate posting much here in the foreseeable future. You can keep in touch at: bsky.app/profile/geomet… Or, as always, what I'm up to on my website: geometrian.com

Braking to rendezvous with a station built into a captured asteroid (or possibly a moon) in orbit around Uranus.

Hacking a bit on my solar system simulator recently. Accurately predicts positions/orientations of astronomical bodies for millennia into past/future. Recently updated the graphics. Atmospheric shader runs *in constant time* (no raymarching). Improvements to do, though.

Machine learning is a magical tool that can solve anything. Input data: .obj files Output data: .jpeg files We can solve graphics. Let's go.
