What HN said
What people liked
Impressive real-time rendering; runs on modest hardware and phones
From 3 comments
This is beyond cool. Point clouds are one thing but this… this is amazing. Kudos and great job. It even runs on my work Lenovo at 60fps.
gabereiser on HNRuns fine on my 2016 iPhone SE. kudos
msk-lywenn on HNIt runs on my mid range phone at 36fps. Did not expect that. Lots of artefacts though, especially if I move the camera.

Looks very cool and impressive demo
From 3 comments
This is really cool! The control scheme is confusing though. Instead of the typical WASD for moving and using the mouse to look around, dragging the mouse moves forwards and…
naavis on HNWow this is insanely cool. If you make it work within ThreeJS, you're going to leave a trace in the history of 3D on the web with that stuff!
crubier on HNWow. I was literally just working on my own implementation. You beat me to it! Great work!

Camera and mouse controls are confusing and unintuitive

naavis on HNBeing brutally honest here, but I just cant get over the control scheme enough to even appreciate the rendering demo. It is unusably unintuitive and awful.
gorkish on HNIt's pretty telling that you had to reach back 26 years to find a control scheme that could be used as an analogy. I don't even know where to start with the mouse controls.…
gorkish on HNI've never experienced this set of mouse controls for a 3D view ever before and was highly confused for a bit.

Visible artifacts and polygon edges when zooming out or moving camera
From 2 comments
When you zoom out there's lots of visible polygon edges that don't look like they should really be there, as if it's trying to draw soft 'blobs' but the texture coords aren't…
bluescrn on HNIt runs on my mid range phone at 36fps. Did not expect that. Lots of artefacts though, especially if I move the camera.

Camera roll is unwelcome
From 1 comment
why the hell is it that anyone who makes these "clever" demos provides the world's shittiest camera that adds unwelcome rolls. late 90s bedroom me is shaking his head.

Support WASD plus mouselook controls
From 1 comment
If you do an update, consider this a vote for WASD + mouselook. It's a ubiquitous scheme among everyone with an interest in real time computer graphics

Integrate with ThreeJS
From 2 comments
This is insanely cool! If you integrate this with ThreeJS you'd have a lot of control options for free! Whilst you're here, I have a question for you: It seems like you don't…

Higher point resolution option
From 1 comment
Is it possible to increase the number of points (resolution) with some setting? I want to see more refined view on a higher end machine.

Why are gaussians not rendered smoothly (sharp edges)?

Does it use the SIGGRAPH 2023 method?
From 1 comment
Does this use the method proposed by Kerbl and Kopanas at SIGGRAPH 2023? https://repo-sam.inria.fr/fungraph/3d-gaussian-splatting/

Can this work for video or dynamic scenes?
From 2 comments
Would this technique work for video? The readme of the inria work[1] seems to imply a model is trained per static scene, does that rule out video? [1]…
gsuuon on HNMy initial understanding is these scenes can’t be made dynamic (animated, physically responsive). Is that correct?

Original Gaussian splatting implementation by Inria
From 2 comments
basically this: https://github.com/graphdeco-inria/gaussian-splatting — a somewhat different approach at rendering 3d scenes.

Media Molecule Dreams renderer
From 1 comment
A thought occurred to me: is this similar to how Media Molecule's Dreams on the PS4/5 renders its scenes?

Goldeneye N64 FPS controls
From 1 comment
It's very similar to the N64 FPS controls (i.e. Goldeneye): arrow keys (joystick) for the "primary movements" of forward/backward and yaw, with which you can move and look…
