Key Points

  • The post announces a beta release of a local, open-source desktop app that generates 3D meshes from images, emphasizing on-device processing.
  • It currently supports Hunyuan3D 2 Mini and is designed to be modular through an extension system to add more open-source models.
  • The author is seeking community feedback on features, useful export file formats, initial model support priorities, and what would make the tool compelling to users.
  • The project is hosted on GitHub at https://github.com/lightningpixel/modly and was shared on Reddit two weeks after an initial inquiry.

I posted a question about this idea here two weeks ago, kept working on it, and now I finally have a beta to show.

It’s a local, open-source desktop app that generates 3D meshes from images.

Right now it supports Hunyuan3D 2 Mini, and I’m already working on support for more open-source models. The app is built around an extension system to keep it modular.

It’s still very early, so I’d genuinely love feedback from people here.

I’m especially curious about a few things:

  • What features would you care about most ?
  • What kinds of file export extensions would actually be useful ?
  • Which open-source models would you want supported first ?
  • What would make something like this worth using for you?

If anyone wants to check it out, here’s the GitHub :
