Class GaussianSplatLoader

Loads compact .splat 3D-Gaussian-Splatting files into a SceneModel (baked RGB, no SH).

Like every other format loader it targets a SceneModel through the ModelLoader base, so splats import as "just another model":

const sceneModel = scene.createModel({ id: "splatScene" }).value;
fetch("scene.splat")
  .then(r => r.arrayBuffer())
  .then(fileData => new GaussianSplatLoader().load({ fileData, sceneModel }));
Copy

Produces one GaussianSplatsPrimitive geometry + a mesh + an object. Headerless format ⇒ a single "*" version.

Splats load in their native .splat/COLMAP frame (authored Y-down). To stand a scene upright in the SDK's Z-up world, configure the source frame on the SceneModel's coordinateSystem at creation rather than baking a correction into the geometry — the SDK premultiplies the model's meshes into the Scene frame for you.
