  This tech reminds me of that Source Code(2011) movie for some reason.

  This for some reason reminded me of the "Killerspiele" debate [1] we had in Germany after a dramatic school shooting. The shooter had previously built a map of the school in Counter-Strike. With this it's not a long stretch from there to having a realistic map of a school... Which would have given him a better rating than the one he got for his map: "I'd like to see the school that actually has lighting like this." [2] Hopefully this tech will never used for something like this.

  Plays decently smooth on my M4 Max. It's probably still a long way from being a production-ready replacement for meshed environments, but I could imagine a hybrid mode where certain elements like grass and shrubbery are drawn with gaussians, perhaps with support for basic procedural animation. Great work with the playable demo!

    For me, the biggest issue this solves is the blank canvas paralysis problem. Artists are visual thinkers and need a little nudge in the right (art) direction. This is a great way to fill that blank sheet of paper with something that they can take and run with.

      Editing Gaussian Splats is still a pain in the ass in the artist's perspective. Even if you can create a good-enough first try using scanned data or generative AI, you just end up with a rough draft that you cannot polish in any way. Existing mesh-based tools allow you to edit the geometry relatively easily, since they are in a higher level discrete representation rather than just a point cloud data structure.

    Thanks! Yeah hybrid is a way forward, dynamic stuff is not easy

  I’m trying to understand from the video why this is better, it looks like a normal high resolution textures with precooked shadow maps.

  It has no dynamic lighting or effects, which makes the video look like a high quality game from 2006.

    dynamic objects are still largely unsolved problem, I just tried to approach it in this demo. also this particular place doesn't have reflective surfaces, but technology supports it - check for example this splat https://superspl.at/scene/ff1d0393 or this one https://superspl.at/scene/6c822f84

      This is better, but I think that a demo with more reflections and radiosity would be much more impressive

  Sort of unfortunate that one ends up putting normal meshed characters that clash with the photorealistic splat environment

    Probably for the best as, well, they are being pumped with lead.

    idealy it should be 4DGS but we are far away from it - real actors scan etc.. but somebody will do it later i am sure

  I'm looking forward to seeing what will happen when gaussian splatting can be combined with DLSS 5. Gaussian splatting has a lot of potential in video games yet to be realised.
