Viewing Splats

Once you've created a Gaussian splat, you'll want to preview and evaluate it before proceeding to editing or integration into your projects. The PlayCanvas Model Viewer provides a convenient way to quickly view and inspect your splat files without needing to set up a full PlayCanvas project.

PlayCanvas Model Viewer​

The PlayCanvas Model Viewer is a web-based tool that allows you to instantly preview 3D content, including Gaussian splats, directly in your browser.

Supported Splat Formats​

The Model Viewer supports three commonly used Gaussian splat formats:

  • PLY files (.ply) - Standard uncompressed splat format
  • Compressed PLY files (.compressed.ply) - PlayCanvas compressed (quantized) format
  • SOGS format (meta.json + WebP images) - Super-compressed format

How to View Your Splats​

  1. Visit playcanvas.com/viewer

  2. Drag and drop your splat onto the viewer

    • For PLY and Compressed PLY files: drag the individual file
    • For SOGS format: drag the parent folder containing meta.json and WebP images
