override partial Int64	GetFeatureIdForVertex (Int64 vertexIndex)
	Gets the feature ID associated with a given vertex.The feature ID can be used with a CesiumPropertyTable to retrieve the corresponding metadata.This returns -1 if the given vertex is out-of-bounds, or if the feature ID set is invalid.

override Int64	GetFeatureIdFromRaycastHit (RaycastHit hitInfo)
	Gets the feature ID from the feature ID set using the given raycast hit.This returns a more accurate value for feature ID textures, since they define feature IDs per-texel instead of per-vertex. The feature ID can be used with a CesiumPropertyTable to retrieve the corresponding metadata.This can still retrieve the feature IDs for non-texture feature ID sets. For attribute or implicit feature IDs, the first feature ID associated with the first vertex of the intersected face is returned. This returns -1 if the feature ID set is invalid.

Detailed Description

Represents a feature ID attribute from a glTF primitive.

Provides access to per-vertex feature IDs which can be used with the corresponding CesiumPropertyTable to access per-vertex metadata.

Gets the feature ID associated with a given vertex.The feature ID can be used with a CesiumPropertyTable to retrieve the corresponding metadata.This returns -1 if the given vertex is out-of-bounds, or if the feature ID set is invalid.

Reimplemented from CesiumForUnity.CesiumFeatureIdSet.
