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 the following commonly used Gaussian splat formats:

FormatFile ExtensionDescription
PLY.plyStandard uncompressed splat format
Compressed PLY.compressed.plyCompressed (quantized) format
SOG (bundled).sogSuper-compressed format in single file
SOG (unbundled)meta.json + .webp imagesSuper-compressed format in multiple files

How to View Your Splats​

  1. Visit playcanvas.com/viewer

  2. Drag and drop your splat from your file system onto the viewer

    Viewing unbundled SOG scenes

    For SOG (unbundled) format: drag the parent folder containing meta.json and .webp images

  3. Navigate the 3D scene:

    ControlAction
    Left double clickSet orbit point
    Left click + dragOrbit around the splat
    Right click + dragLook around
    Shift + click + dragPan the view
    Mouse wheelZoom in/out
    WASD or Arrow keysMove forwards/backwards/left/right

Open Source and Customization​

The PlayCanvas Model Viewer is open source and available on GitHub. This means you can:

  • Host your own version - Use a local server or deploy to your own infrastructure for complete control
  • Add new functionality - Add support for additional file formats or custom UI
  • Contribute back - Submit issues and pull requests to help improve the viewer for everyone

Viewing already-published splats​

If your splat is already published on superspl.at, you have two viewer-side options that are specific to Gaussian Splats:

  • The public scene page at superspl.at/scene/<hash> — the easiest way to share a splat that's also been curated in Studio (with cameras, animations, annotations, post effects, and collision).
  • The SuperSplat Viewer — the open-source web viewer that powers scene pages, available on npm as @playcanvas/supersplat-viewer for embedding in your own site or self-hosting as a single-file HTML export.

The PlayCanvas Model Viewer described above is still the right tool for quickly previewing arbitrary splat files (and other 3D content), before publishing or as part of a pre-flight check.
