get_object_dag_path_name returns the name under which the object will be exported in the Alembic file. It is of the form "[../grandparent/]parent/object" if dupli_parent is NULL, or "dupli_parent/[../grandparent/]parent/object" otherwise.

Check whether the requested time from the selector falls between two sampling time from the time_sampling. If so, returns a #SampleInterpolationSettings with the required data to interpolate. If not, returns nothing and we can assume that the requested time falls on a specific sampling time of time_sampling and no interpolation is necessary.

AbcUvScope blender::io::alembic::get_uv_scope	(	const Alembic::AbcGeom::GeometryScope	scope,

UVs can be defined per-loop (one value per vertex per face), or per-vertex (one value per vertex). The first case is the most common, as this is the standard way of storing this data given that some vertices might be on UV seams and have multiple possible UV coordinates; the second case can happen when the mesh is split according to the UV islands, in which case storing a single UV value per vertex allows to de-duplicate data and thus to reduce the file size since vertices are guaranteed to only have a single UV coordinate.
