Interesting discussion from start of this year of one of the first popular music videos made with this technology. Some decent explanations in there.

We are converging on text specification to 3D world. Gaussian Splat technology doesn't get as much hype as it deserves. The killer app for VR headsets is still to come.

Every time I hear about Gaussian splatting, I think about triangle splatting[0] - GPUs were built to render triangles, so I wonder what games would be like if we supported generating and rendering them as much as we do Gaussian splats.

They've made a follow up to that called MeshSplatting. https://meshsplatting.github.io/

The Dreams game engine (only for PS4) does this and is able to achieve scenes that no other game engine can. Here's a technical talk about how they did it: https://www.youtube.com/watch?v=u9KNtnCZDMI

Actually sorry not sure if they use triangle splatting, but gaussian splats at least.

For those who use Blender for work, how far are models like Astra away from using Blender to create something good enough at a junior, senior level?

Fable 5.2 is really good at using Blender from my testing. That being said, even smaller models are good enough for junior level work, it just depends on what deliverable or metric you are looking at. Most agentic LLMs can now do low poly assets for example.

Bundle support in geometry nodes is huge for complex pipelines and workflows, particularly when combined with lists and closures. I have been running on the alpha builds to get access to them in my workflows.

It took me a while to properly understand it, but it's genuinely great. It maps so much more of what I expect from traditional coding, scripting etc into the visual paradigm and makes an awful lot easier to use.

Also, should out to databpy and nodebpy, both of which are indispensable and make using nodes and blender so much nicer:

Apparently, while Gaussian splatting is not the core technique for all world models, it has become a dominant representation and rendering backend for spatial and reconstructive world models.
