This library provides a completely native implementation of Niantic Labs' SPZ format, of which the original can be found here.

Let's get straight to the point with an example of how to use this library.

In this example, a compressed .spz file is loaded and serialized to a .ply file.

// Load a .spz file
PackedGaussianCloud packed = SplatSerializer.FromSpz("/path/to/splat.spz");

// Unpack
GaussianCloud unpacked = packed.Unpack();

// Serialize to .ply
unpacked.ToPly("/path/to/splat.ply");

And here's how to compress a .ply to a .spz:

// Load a .ply file.
GaussianCloud unpacked = SplatSerializer.FromPly("/path/to/splat.ply");

// Pack
PackedGaussianCloud packed = unpacked.Pack();

// Serialize to .spz
packed.ToSpz("/path/to/splat.spz");

Gaussian clouds implement IReadOnlyList<Gaussian>, so they can be indexed and enumerated through as a normal collection.

Also included in this repo is a demo library consisting of a simple console app to demonstrate how to use Spz.NET.

Unit tests and a proper nuget release will be coming soon.
