SuperSplat Viewer

This is the official viewer for https://superspl.at and the SuperSplat Editor HTML export.

This webapp compiles to simple, self-contained, static website.

The app supports a few useful URL parameters (though please note these are subject to change):

• &settings=url - specify the URL of the settings.json file (default is ./settings.json)
• &content=url - specify the URL of the scene.compressed.ply file (default is ./scene.compressed.ply)

As well as the following:

• &noui - hide UI
• &noanim - start with animation paused
• &poster=url - show an image while loading the scene content
• &ministats - show the runtime CPU (and on desktop, GPU) performance graphs
• &skybox=url - specify an equirectangular skybox image for the skybox

Settings Schema

The settings.json file has the following schema (as defined in typescript, taken from SuperSplat editor):

type AnimTrack = {
    name: string,
    duration: number,
    frameRate: number,
    target: 'camera',
    loopMode: 'none' | 'repeat' | 'pingpong',
    interpolation: 'step' | 'spline',
    keyframes: {
        times: number[],
        values: {
            position: number[],
            target: number[],
        }
    }
};

type ExperienceSettings = {
    camera: {
        fov?: number,
        position?: number[],
        target?: number[],
        startAnim: 'none' | 'orbit' | 'animTrack',
        animTrack: string
    },
    background: {
        color?: number[]
    },
    animTracks: AnimTrack[]
};

Example settings.json

{
  "background": {"color": [0,0,0,0]},
  "camera": {
    "fov": 1.0,
    "position": [0,1,-1],
    "target": [0,0,0],
    "startAnim": "orbit"
  }
}
