these goddamn distance fields are gonna haunt me for the rest of my life, aren’t they (rangers FC stadium, glasgow)

and finally, the full end credits theme from outer wilds, which should be straight up illegal to perform in a public setting (it destroyed me for the Nth time)

some of my own highlights: there was a gorgeous orchestral cover of eurydice’s “good riddance” from hades

making your own mochi is honestly pretty fun - just gotta remember to snap a photo before half of them get eaten D;

I don't know what I was smoking at the time, or why/how my supervisor signed off on it, but this was a figure that made it into my thesis report

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

A graduate school lecture on directional field processing

Paper presentation on progressive convex hull simplification

A keynote lecture on resource-efficient visual computing, by one of the inventors of Gaussian splatting

So, funny story. I've seen this snippet of the CuRast paper probably 2, 3 times in a month. Added it to the pile, thinking "this'd be a cool trick to use someday". Then I clock into work Thursday morning, browse old code to rework some tests...

Also, don't usually liveblog anime on here but *god damn* does Kamiina Botan have some drop-dead gorgeous splash screens

All it took was over a month of procrastination + being bedridden with a fever, but I've finally gotten how Brian Karis' GPU MPMC queue works ... now to figure out something interesting to use it on

My tree is constructed top-down, i.e. starting from the root and subdividing. if a cell is fully inside/outside the surface, it's deleted, otherwise we split and recurse (see this drawing (by @mattkeeter.com) which shows the deleted cells)

turtlespook @turtlespook.bsky.social · 29/03/2026

It's the large cell that poses problems. We can't compute a vertex for it since it has no edge crossings. But it also can't be discarded without introducing cracks: it still contains a piece of the continuous isosurface (crappily drawn in purple). What do? 3/3

turtlespook @turtlespook.bsky.social · 29/03/2026

Hi friends, while implementing dual contouring, I ran into an edge case that I'm not sure how to deal with. Here's the problematic configuration: a coarse cell + 2 fine cells. There's a single (red) corner which lies inside the isosurface, and the remaining (white) corners are on the outside. 1/3

Btw, tip I learned the other day that would’ve saved me a ton of closing and reopening windows

I got a pretty similar plot for the 2D case!

spent this week learning to use SIMD intrinsics with everyone's favorite fractal. I'm surprised at how the numbers turned out: between the 8-wide AVX instructions and 12 CPU threads, we can get pretty close - within 1/8x! - to the compute shader's performance

one cool feature of direct raytracing is that you can model full-blown lens systems - in this case, the famous Helios-44M lens used for the new Batman movie and Dune. the bokeh swirl in the background is really satisfying to watch!

hi there! I'm just a regular nerd who's drifted through a few hobbies over the years - the latest being graphics and geometry. here's some screenshots from a recent project on camera simulation. point spread functions can get pretty wild!
