Class TrackingLayer3D


  • public class TrackingLayer3D
extends InternalHandle
    3D tracking layer class.

    The 3D tracking layer works like a 2D tracking layer. Each scene window has a tracking layer. To be precise, each scene is displayed with a tracking layer. The tracking layer is a blank transparent layer, always at the top of each layer of the map. It is mainly used to temporarily store some graphic objects, some texts, etc. during a processing or analysis process. As long as the scene is displayed, the tracking layer will exist. You cannot delete the tracking layer or change its position. In addition to supporting the addition of 2D objects, 3D tracking layers also support the addition of 3D points, lines, polygons, and model objects.
