Inspired by Nokia's IBC 2026 demo of streaming Gaussian splats over DASH, we cut one of our own splat scenes into a quality ladder, from 1.2 MB to 14 MB, with a manifest like a video stream's. The browser shows the smallest version at once, measures the connection, and swaps in sharper versions as they arrive.
What we measured
| Measure | Download the whole scene | Stream the ladder | Note |
|---|---|---|---|
| First 3D view, 20 Mbit/s | 5.6 s | 0.5 s | |
| First 3D view, 5 Mbit/s | about 22 s | 1.9 s | Settles on the 300k version at 7.4 s |
| Match to full scene, T0 · T1 · T2 | n/a | 13.9 · 19.7 · 35.1 dB | PSNR over six viewpoints |
| Ladder sizes | n/a | 1.2 · 3.3 · 13.0 · 14.0 MB | |
| Full colour detail costs | n/a | +1 MB | Spherical harmonics degree 3 against 1, in SOG |
What happens next
- Additive streaming, where each rung adds Gaussians instead of replacing the last.
- Moving splats: per-segment 4D Gaussians on the same ladder, towards what Nokia showed.
- Our own capture instead of a rendered scene.
The book behind the lab
Get the book today: learn Gaussian splatting and apply it to real projects.
People keep asking how we build what you see here. The book walks students, educators and practitioners from a drone clip to a measured 3D in the browser, with hands-on labs and the code.
Launch price until 3 December.
