Gaussian splattings tools

Project description

splattools

A collection of utility tools for working with Gaussian Splatting PLY files.

Features

  • info: Get basic information about a Gaussian Splatting PLY file (vertex count, properties).
  • remove-sh: Remove spherical harmonics coefficients from a PLY file, leaving only the DC components (colors). This significantly reduces file size while maintaining basic appearance.

Usage

After installation, the splattools command will be available.

Get PLY Info

splattools info path/to/model.ply

Output:

Vertex count: 123456
Properties: x, y, z, opacity, f_dc_0, f_dc_1, f_dc_2, f_rest_0, ..., scale_0, ..., rot_0, ...

Remove Spherical Harmonics

splattools remove-sh input.ply output.ply

This command extracts only the essential properties (x, y, z, opacity, f_dc_0, f_dc_1, f_dc_2, scale_0, scale_1, scale_2, rot_0, rot_1, rot_2, rot_3) and saves them to a new file.
