Yeah, but isn't still the expected outcome to end up with actual 3D objects, not point clouds? Or did people start integrating point clouds into their 3D workflows already? Besides for stuff like volumes and alike, I think most of us are still stuck working with polygons for 3D.
I use pointclouds all the time in Rhino/Lastools/Meshlab I much prefer pointclouds and nurbs over meshes Not everything is gamedev

Agree, I'm not sure why you'd think that's the only use case for 3D, unless I misunderstand your argument here.
How would you handle visual effects with point-clouds for example? There are so many use cases for proper 3D, and all I can think of as use-case for point clouds are environments with static lightning, which seems like a really small part of what people generally consider "3D scenes".

My understanding is that it is not mesh, it’s Gaussian Splatting. There are tools to convert Splats into mesh though.

Not necessarily.
If you're using it to render video you don't need to go into the mesh world.

You can convert splats into meshes using a simple marching cubes algorithm. But the meshes produced are not easy to edit.
Generating good meshes sounds like a problem for a completely different machine learning algorithm to me.

#45I’m imagining this approach being combined down the line with your typical photogrammetry approach for reinforcing quality.

Maybe I missed the mark on “gamedev”, but 3D is larger than just “aesthetically pleasing 3D VFX” for its own sake
Often I’m trying to use something as a reference for a design where a 3D model isn’t the actual end goal, or I’m performing analytics on a 3D object (say in my case for a lot of GIS and simulation work)
The whole “mesh is the be all and end all of 3D modelling” irks me as while yes it’s a really important way of representing an object (especially with real time constraints), it doesn’t do justice to the full landscape of techniques and uses for 3D
It would be like 2D sprite artists from the gamedev world saying “what’s the point of all this vector art you illustrators are doing” or “what’s the point of all these wireframe designs you graphic designers are doing” - “these aren’t raster images!”
I suppose my snipe was trying to communicate the idea that 3D is larger than just a vehicle for entertainment production. It intersects many industries that may eschew polygons because real time rendering is irrelevant
3D tooling has uses beyond producing 3D scenes, just as Photoshop is used for more than touching up photographs
Edit: for anyone stuck in a rut with meshes come join the dark side with nurbs - it makes you think about modelling in a radically different way (unfortunate side effect is it makes working with meshes feel so so “dirty”)

#47We’ll hopefully convert an LLM into a 3D haunted house and finally democratize AI interpretability by having millions of gamers walking in them
Re: Bolt3D: Generating 3D Scenes in Seconds
#48ok, thx

No one said this, it seems like you are making up fake questions and not dealing with the actual questions that the person you replied to asked.
You can view point clouds and you can warp them around, but working with them and tracing rays becomes a different story.
Once you need something as a jumping off point to start working with, point clouds are not going to work out anymore. People use polygons for a reason. They have flexible UVs, they can be traced easily, they can be worked with easily, their data is direct, standard and minimal.

Expected by whom? Other researchers in this space? That's the audience for this work.
