GltfGpmLocal
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 theanchorPointsIndirectandintraTileCorrelationGroupsare present.When the storage type is
StorageType.Direct, then theanchorPointsDirectandcovarianceDirectare present.
Parameters
An object describing initialization options

Types
Initialization options for the GltfGpmLocal constructor
Properties
Array of stored direct anchor points
Array of stored indirect anchor points
The full covariance of anchor point parameters
Metadata identifying parameters using same correlation modeling and associated correlation parameters
Specifies if covariance storage is indirect or direct.
