Description

Multi-Track Object (MTO) interface.

Object Model

Public Properties

Analysis	Get the MTO's spatial state.
DefaultTrack	Get the default MTO track.
GlobalTrackOptions	Get the global MTO track options.
Graphics	Get the MTO's 2D Graphics properties.
Tracks	Get the collection of MTO tracks.
VO	Get the MTO's 3D Graphics properties.

Example
