...and of course highly specialized fancy UI visualization in home computer emulator debugging UIs, like here in my Bombjack emulator ;) (I would really love to see regular emulators having a powerful plugin interface for adding Dear ImGui visualizations)

used to feel guilty that I often re-made the 'same' projects over and over again through my career. the set changed slowly, but, texture mappers, sdf raymarchers, audio engines, ugc 'engines', in-memory databases... but I no longer feel guilt: only fascination that they end up different every time!

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...

eric - my latest toy has meandered from code editor to arrangement ui back to code again. the fun thing is theres no synth engine - its just raw functions called at audio rate all the way down. the clicks in this bad vid are because its my laptop's mic recording its own speakers, as I press keys

today's alex-mega-gamedev-tip: one of my favourite passtimes is getting deep into design thoughts on whatever im working on; on walks, in the shower. but dont let the thinking get more than about 1 day ahead of the process of actually making it. any more, and you're probably wasting your time... 🧵

went to a screen printing class with the kids and tried to make a tote bag with a bundle of patch cables but then i accidentally screened his face on side ways!!! argh. roll lil buddy, roll

After a solid run of about 13 years at Double Fine, It seems I have found myself with an abundance of free time. If you know anyone hiring for games VFX, please let me know!

try to follow along with 3d reconstruction literature but a lot of the work (surely v cool) is in a similar place to shadowmap papers in the 00s: selotape together a new combo of recent techniques, show improvement on some scenes. this kind of 'kitchen sink' complexity makes me want to wait it out

tl;dr: RoMa v2 + MFT + DAv3 + MegaLoc + different handling of sequential tracking and loop closure + metric-scale GLOMAP with depth priors

this is such brilliant work. id never have thought to fit toruses, but nicole's explanation below makes it seem so natural in hindsight. and then packs 9000 other awesome connections to other hard problems into one paper. chapeau to her & the co-authors

At #SIGGRAPH2026, I presented "points as tori" (PAT) for fast pointwise evaluation of signed distance for point clouds. Some code (Python w/ C++ extensions) and demo up: github.com/nzfeng/point... Contributions from people/LLMs welcome. Explainer thread below for the project: 🧵

just need to vent. saw this pop into my inbox & involuntarily blurted out loud 'oh F OFF'. im not even 'that' anti AI (well, its a journey & im pointed that way...) the product evangelism UGH i understand the mechanisms; just F OFF ALREADY cant wait for this ~universal sentiment to reach the C suite

bought a noname brand volume knob off amazon for a tenner. its just a little metal enclosure, a bog standard pec11 encoder, 6 rgb leds, and a magnet in the base. no docs but opened it up revealing a brand, and that was enough to figure out the HID report to change led colour.

kids binging taskmaster on channel 4 so i get to experience infinite 'weirdly crisp, clean, colour balanced' euro ad style. i hate it so much. its such a noticable 'look du jour'. kinda 4k rendered/ai looking. even when (somewhat) real footage. intentionally. i dont get the appeal at all.

does anyone know of any editor type apps (in any domain) that do something interesting for the case of 'show me the properties of some clicked object?'. ye olde 'inspector pane on the side of the screen' is the default, but are there cuter ways? a popup window over the object itself, obviously... hm
