Screen Mapping

Instructions for use

"Screen Mapping" button to add pictures to the scene in the Scene. The image in "Screen Mapping" Add to Scene is actually a Screen Layer added to the scene. A scene contains only one Screen Layer, and multiple image objects can be added to the Screen Layer.

Screen Layer is a special layer. Unlike other 3D layers, Terrain Layer and Image Layer, objects in Screen Layer are not placed on the earth in the scene according to the coordinate information of the objects. Instead, it is placed somewhere on the screen (Scene surface) according to the specified screen coordinates, so the objects on the Screen Layer do not change with the rotation, tilt, enlargement, reduction, and other operations of the sphere in the scene. The objects on the Screen Layer are static relative to the Scene. In this way, you can use the Screen Layer to place content that needs to be displayed in the Scene, such as Logo and explanatory text.
