int GetPointId
(
int Index
)

Remarks

Returns the point Id of the point at the given index.

Each point has a unique identifier (within a session) that is persistent across frames. That is, if a point from point cloud 1 has the same id as the point from point cloud 2, then it represents the same point in space.
