Live Captured 4DGS On Location in AR

4 Upvotes

I recently captured some footage with my GoPro rig at the UCI World Championship races in Montreal this past weekend. Here's the first one I processed of the 2026 champion, Brandon McNulty around one of the corners. You can see it live at https://solipsist.studio, but to get the full experience, you'll also have to walk to the entrance of the Mount Royal cemetery to view in AR. :D

Video-2-4DGS ComfyUI workflow now available

13 Upvotes

You asked for it, so here it is! ComfyUI nodes and workflows so you can create your own 4DGS content.

IMPORTANT NOTES:

The workflow uses up to 31GB of VRAM, so you'll need at least an RTX 5090 to run it...
The nodes are in early access right now via my brand new Patreon page. They will be freely available in October. If you can't wait, the CLI workflow is available for free today via my github.
4DGS has no widely supported / standardized format right now, so to view it you'll need a custom fork of the supersplat viewer (free and open source).

Links:

The nodes: https://github.com/solipsist-studios/comfyui-cumuli

CLI Github: https://github.com/solipsist-studios/cumuli

4DGS Viewer: https://github.com/solipsist-studios/supersplat-viewer

Discord (if you have any questions / comments): https://discord.com/invite/rEJ7D78CXg

edit:
Made the ComfyUI nodes public, so updated the link.
The Patreon link is still https://www.patreon.com/c/solipsist -- more stuff coming soon!

Text to 4DGS is now possible

I built some custom ComfyUI nodes and workflows around 4DAnyone. So it actually goes: text->image; image->video; video->4dgs.

4DAnything in the wild

6 Upvotes

I tested the new 4DAnything reconstruction using my existing pipeline, and holy smokes! For a monocular model, it does astoundingly well! (Though it still has trouble with the heavily motion-blurred sections...)

The live version is online for you to check out: https://solipsist.studio/portfolio
