WorldWind Kotlin/earth.worldwind.layer.ogc3d.content/GaussianLoader

GaussianLoader

Pluggable codec for Gaussian-splat 3D Tiles content. The engine has no built-in Gaussian-splat parser today — apps wire one in by setting earth.worldwind.layer.ogc3d.Ogc3dTilesLayer.gaussianLoader.

Why an external hook: there is no single settled wire format yet. Niantic's SPZ has one header, Cesium's draft EXT_3DTILES_gaussian_splat embeds in glTF, SuperSplat's .splat files have no magic at all. Each codec implementation lives in its own module and registers itself per layer; the engine stays codec-agnostic.

Implementations are stateless and shareable across layers.

Functions

parse

abstract fun parse(bytes: ByteArray): GaussianPayload

Parse bytes into a GaussianPayload. Called only after supports returns true. May throw to signal a malformed payload — the layer treats throws as a tile load failure (the tile transitions to FAILED and stays without content).

supports

abstract fun supports(bytes: ByteArray): Boolean

Cheap magic-bytes / shape check. Returns true when this loader can parse bytes. Must not allocate or throw — called once per fetched payload before the engine decides which loader pipeline owns the content.
