The talk I presented at #SIGGRAPH2026 is now available on YouTube, for anyone who couldn’t attend or would like to revisit it :) youtu.be/OFJYBUArVPc?...

1/6 Excited to share our #SIGGRAPH2026 paper, Dual Contouring of Signed Distance Data! We propose a new method for reconstructing sharp meshes from discrete samples of signed distance functions (SDFs) that does not require gradients. Project page: gatc.cs.columbia.edu/projects/dua...

Proud of myself today. What started as a simple infinite-grid shader turned into a month-long journey through rendering, maths, and plenty of frustration—but I finally got it working. I wrote about everything I learned: willofindie.com/proj/infinit... #webgpu #rustlang #glsl #realtimerendering

Infinite Grid Shader

Learning to create an infinite grid procedurally using GLSL shaders. This post contains my notes, lessons and findings, and is intended for personal reference. Therefore, you might find errors, misjud...

Hopefully one last SIGGRAPH advertisement. I, myself, yours truly, will present on Haolin's behalf a data-driven method for joint adaptive sampling and quadrature for integration. Wed R408A. In the end of the talk I'll argue why everyone is doing the wrong thing. Paper: suikasibyl.github.io/nqr

Tomorrow at #SIGGRAPH2026 (Monday) @ 3:45-5:35pm, come to the papers session "Creating & Iso-Surfacing SDFs" in Room 408B. A paper I'm looking forward to is "Subgrid Marching Tetrahedra" by Hossein Baktash (yes, I'm biased as his labmate, but it's a great idea) [1/n]

I went on a small side-quest this week after reading about the "waterfall scheme" presented [here](gpu-primitives-course.github.io) and trying/failing to find examples of it in the wild. turns out people just use different names for things: in prefix sums, it's called the "chained scan"

GPU Programming Primitives for Computer Graphics

Abstract The course introduces programming primitives for parallel algorithms on GPUs for a wide variety of applications in computer graphics. Various parallel algorithms can be decomposed into progra...

JKR and her new org apparently helped get the new Amnesty International report on how TERF organizations destroy lives taken down from their site. Well, guess what? The Streisand Effect is real. Here's the entire report in a thread. Read it. Share it.

Amnesty International put out a major report documenting the influence of UK based anti trans gender critical organizations and their funding. Within hours, GC groups threatened defamation lawsuits and Amnesty was forced to pull it down. Proving the point they're anti rights. Anyways, here it is.

I love good games and I care deeply about the people who make them. I'm sick to death of the *military-grade denial* I've seen from nearly all corners on just how grim things have been looking. I worry that game dev has already crossed into *no longer a career, but could be a hobby* territory

I’m not super invested in the AAA side of the games industry, but god, to gut *Id Software* of all people… I really loved their engine & rendering tech talks in recent years. so much institutional knowledge and expertise being thoughtlessly flung into the void

If they ended up decimating id Software's tech team then I have no faith in anything they'll ever do again under the current leadership. Between last week and today's news...I just don't know what to say at this point.

my #1 grizzly beard protip for (game) dev is: if you have a bug that you dont understand the cause of immediately, dont try to fix it; add & iterate visualization / inspection tools until the cause is plain to see. the accumulation of 'observability' in your system's state will pay off many times

attended a graphics conference for the first time! having known a lot of these names through papers and youtube videos and tweets, it’s kinda surreal to have met the real flesh-and-blood people behind all the cool research
