Inheritance diagram for CesiumGltf::FeatureId:

Public Attributes
int64_t	featureCount = int64_t()
	The number of unique features in the attribute or texture.

std::optional< int64_t >	nullFeatureId
	A value that indicates that no feature is associated with this vertex or texel.

std::optional< std::string >	label
	A label assigned to this feature ID set. Labels must be alphanumeric identifiers matching the regular expression `^[a-zA-Z_][a-zA-Z0-9_]*$`.

std::optional< int64_t >	attribute
	An integer value used to construct a string in the format `_FEATURE_ID_<set index>` which is a reference to a key in `mesh.primitives.attributes` (e.g. a value of `0` corresponds to `_FEATURE_ID_0`).

std::optional< CesiumGltf::FeatureIdTexture >	texture
	A texture containing feature IDs.

int32_t	propertyTable = -1
	The index of the property table containing per-feature property values. Only applicable when using the `EXT_structural_metadata` extension.
