Help - 3D Gaussian Splats Viewer

info Introduction

This viewer application displays 3D Gaussian Splatting (.PLY, .Splat, .SPZ) in various stereoscopic formats (SBS, Anaglyph, Interlace, etc.), allowing you to freely explore 3D space with mouse or touch controls.

You can switch between two viewer modes optimized for different models:

3DGS Viewer: Best for models created with Luma AI or mobile apps like Scaniverse.
SHARP Viewer: Optimized for models generated from 2D photos using Apple's ML-SHARP.

It also features a Half-SBS output mode for 3D TVs and 3D projectors, perfect for large-screen 3D viewing. As a web-based app, it works seamlessly on browsers across all platforms.

💡 For iPhone Users: Select "Add to Home Screen" from the Safari share menu to use it as a full-screen native app.

file_open How to Open 3DGS Files

You can load models using either of the following methods:

Select the folder icon folder_open on the far left of the toolbar and choose "Open File".
Drag and drop 3DGS files directly onto the viewer.

📂 Multiple Files: Both methods allow you to select multiple files at once. When multiple files are opened, use the NEXT / PREV buttons on the toolbar to switch between them.

compress Conversion & Saving (.spz)

This app also functions as a powerful file conversion tool.

Input: Supports .ply and .splat formats.
Output: Save models in the proprietary .spz format.

🚀 Benefit: Saving in .spz dramatically reduces file size while maintaining visual quality—perfect for web sharing.
