GltfGpmLocal

external class GltfGpmLocal(options: GltfGpmLocal.ConstructorOptions)(source)

The GPM metadata for a Ground-Space Indirect implementation stored locally (i.e. a tile and/or leaf node).

This reflects the root extension object of the NGA_gpm_local glTF extension. When a model that contains this extension was loaded, then an object of this type can be obtained by calling

const gltfGpmLocal = model.getExtension("NGA_gpm_local");

The storage type determines the presence of the optional properties:

When the storage type is StorageType.Indirect, then the anchorPointsIndirect and intraTileCorrelationGroups are present.
When the storage type is StorageType.Direct, then the anchorPointsDirect and covarianceDirect are present.

Parameters

options

An object describing initialization options
