Introducing Comfy Previs, my #OpenSourceHiggsfield submission.
Direct AI video on @ComfyUI with @threejs / @Blender blockouts, camera presets and keyframes, phone/gamepad controls, cast references, style controls and auto-prompting.
Pick your favorite models. Know the cost before you press Generate. Bring your own AI agent through MCP.
Demo: sbobyn.github.io/comfy-three…
Code: github.com/sbobyn/comfy-thre…
#ComfyUI #threejs #Blender
Build → Cast → Shoot → Generate → Cut.
Try storyboard stills before video. Inspect the scene-linked prompt, compare models, review the quote and set spending caps.
The demo is read-only. Install locally to edit and generate with Comfy Cloud or local ComfyUI.
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.
Built on top of three-avbd: github.com/sbobyn/three-avbd
#threejs #webgpu
Ok the Teardown-inspired @threejs voxel destruction demo is live! is live!
Try it here three-voxel-destruction.verc… added two more scenes - race track 🏎️ and spacestation 🚀

110k rigid bodies in real time, in a browser tab. Grab anything, fire cannonballs.
Built with Claude Opus 5.5: Augmented Vertex Block Descent (SIGGRAPH 2025, Giles, Diaz & Yuksel) in WebGPU with @threejs . It's a physics solver that stays stable with huge scenes and big mass ratios. Opus 5.5 even put together this whole demo reel video just from a single text prompt in Claude Code haha 🤯
Try it: three-avbd.vercel.app
(recorded on an M4 Max, lighter scenes run fine on older computers or on mobile)
Code's here, MIT licensed. Go build something with it, have fun breaking things: github.com/sbobyn/three-avbd
#threejs #WebGPU
Been reviving the path tracer I built last fall with @threejs and WebGL2 shaders.
Added Raster/path-traced comparisons, camera-ray visualization, device performance calibration, an interactive BVH inspector, and more.
I wrote the original myself, but had a lot of help from GPT-5.6 Sol (and recently Astra) this time around. Pretty impressed with how much cleaner it’s become with little manual coding. Astra even recorded these demos directly from the app haha.

#threejs
Started working on an interactive WebGL-based pathtracer this past week!
It's integrated with Three.js for scene management, debug rendering, and interactive controls.
#threejs #webgl #raytracing #pathtracing
So far, the implementation follows book 1 of @Peter_shirley 's raytracing series
Next I'm planning on adding
- textures, quads, and area lights, skybox lighting
then
- triangles + mesh loading
- fragment shader → compute shader
- scene uniforms → data textures
- bvh
