The product, not a mockup
From received
to understood.
A real four-step path for 3D creators, developers, and spatial teams who need to review a delivery file away from the desktop.
02 · Check
See the file plan before the full load.
Preflight identifies the detected format, scene size, resource estimate, and a recommended next action.
Format evidence · resource estimate03 · View
Give the scene the screen.
Once the file is ready, the viewer stays visually quiet so you can review the Gaussian splat itself.
Focused canvas · restrained controls04 · Inspect
Keep technical evidence within reach.
Open the Inspector for detected layout, Gaussian count, spherical harmonics, bounds, and compatibility details.

Why preflight
An extension is a clue.
The file is the evidence.
Instead of trusting the extension and attempting a full load, Boreal Splat reads the smallest useful truth first. A difficult, mislabeled, or unusually heavy file should fail with useful context—not after an unexplained wait or risky allocation.
- 01Read the smallest truth
Check the header, version, schema, element count, property types, and offsets.
- 02Estimate the device load
Plan CPU and GPU resources before buffers scale with every Gaussian.
- 03Open—or stop clearly
Proceed with an explicit plan, adapt display quality, or preserve the source and explain why.
Formats & privacy
Three familiar endings.
One careful opening path.
Boreal Splat validates the contents before loading. Support for an extension never means every schema carrying it is compatible.
01 .PLY 3D Gaussian Splat PLY
Common 3DGS schemas are the validation target. Ordinary point-cloud PLY files are identified separately.
02 .SPZ Niantic SPZ
SPZ versions 1–4 are in the validation scope, with explicit version and file-integrity checks.
03 .SPLAT Packed splat files
Known packed layouts are checked before decode; malformed lengths or unsupported layouts are rejected clearly.
Scope note
Current paths cover common 3DGS PLY schemas, SPZ versions 1–4, and known .splat layouts. The app does not claim universal compatibility.

What to inspect before opening a Gaussian splat
Inspect the header and property layout before allocating large CPU or GPU buffers. A safe preflight identifies the real schema, estimates decoded resource needs, and preserves the source when the file cannot open safely.

PLY, SPZ, and .splat: the extension is not the schema
Treat PLY, SPZ, and .splat as different container families—not compatibility guarantees. A reliable viewer verifies each file's header, version, record layout, and decoded resource plan before rendering.
