It’s amazing this runs perfectly smooth on my iPhone 12 mini

That is indeed a very cool scene being about to wander around and still have decent resolution

Ah the timeless joy of falling through the floor geometry.

Seriously though - it's breathtaking.

The first guy who figures out the bridge between splats and dynamism - animation, editing, responsiveness - is going to be one of the immortals of 3d design.

There are many ways to represent 3D data, but animations really only work properly with polygon meshes (e.g. triangle surface meshes or volumetric tetrahedral meshes).

I don’t know. Maybe today, but tomorrow?

If you can sample points inside a volume, in theory you could do that with splat geometry. If someone figures out a way to pass in animation time to a sampler, sample along geometry/wireframe or something else, and keep it from overly twinkling it might change everything.

I’m hand waving all the complexity into “if done one figures out”, of course.

I just don’t see why this method can’t evolve in the way diffusion models have evolved (knowing very little of the geberative mechanics of splats).

But the mesh is itself an abstraction, you just need to build that bridge.

We've been leaning away from pure polygons for decades, anyway. Vertex skinning, SDFs, volumetrics, simulation, and a lot more.

The meshes in a From Software game are for exmple hilariously simple, most of the animation is force simulation to make the famous "frizzles" that they like.

Vertex skinning is essential for animation and it only works with polygons.

		I'm not sure that's completely accurate? Vertex skinning isn't (necessarily) tied to polygons . . but to having points (or any parameterized features) that can be transformed by a weighted blend of matrices. The "vertex" in "vertex skinning" is really just "a thing with a position that gets moved." p' = Σ wᵢ · Mᵢ · p It's just a position. Triangles can come along for the ride downstream, but they're not essential, which is one of the reasons it's so efficient for some stuff. Polygons are the optimal surface - but surfaces are often extraneous. Take all this a few hefty grains of salt, I'm an amateur in the field. My 3d/CAD work is strictly in support of my enterprise stuff. And making wicked battlemaps for gaming VTTs, natch. But I will stand by the overarching statement that polygons are in fact an abstraction, and bridging that abstraction with whatever is in splats would be wicked awesome.

You pretty much just need a representation that can be constructed reasonably and interpolated.
