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:

Format	File Extension	Description
