For larger projects I've found Linear + Obsidian + custom skills really helpful.

Linear for scoping work, acceptance criteria, and tracking tickets through PRs. I use independent review subagents to check that implementations meet requirements and actually use existing libraries/systems.

Obsidian for maintaining shared context (research notes, design decisions, rough plans that aren't ready for Linear, etc).

It's not perfect, and can feel pretty wasteful of tokens, but it's helped a lot with keeping agents aligned with my intent.

That said, I haven't actually been reading much code for the past month+, so there could be absolute garbage hiding everywhere lol. At this point, I've accepted that the next model release might be able to audit and clean things up faster than I could manually chase them down today 🤷‍♂️

Preview of a real-time @threejs destruction library I've been working on!

Lots more demos in progress, may do a technical breakdown on here of how it works.

Will open-source it once it's more polished.

@dangreenheck Awesome work!! Excited to check this out

[sbobyn @nybobs]

@The_MrAI @threejs Yep! Not sure if that’s a criticism or just an observation haha. The goal was a quick test of AVBD for convincing real-time rope, sail and flag motion on an existing ship asset. It’s definitely an approximation, but I’m pretty happy with how it turned out so far!

Been working on a @threejs WebGPU fluid simulator for a while. Lots still cooking, but here's a preview 🧑‍🍳

More details and demos coming soon!

@iabom @threejs Not yet, will post a link soon after I polish the demo a bit more!

[sbobyn @nybobs]

@Riftv_ @threejs It's not in the three-avbd repo demos, but I will put it up soon as a separate repo I just need to do some more polish on it first

[sbobyn @nybobs]

@Erica_Codes_NJ @threejs Not yet! Will put it up soon as a separate repo

[sbobyn @nybobs]

Good question! Honestly it depends a lot on the scene (how many pieces are touching, solver iterations, frame budget for rendering, what machine your on, etc).

But roughly, the solver alone handles ~100k+ boxes in a few ms per frame on an M4 Max. I'll stress test this scene tonight and post the results.
