The Scene Properties panel provides functions for setting the display of the ground surface in a 3D Scene.
Scene Type
- Spherical surface: The scene of the surface layer of the earth is displayed in the form of a sphere simulating the three-dimensional space of the earth.
- Plane: Expand the spherical surface of the earth into a plane, and simulate the whole earth to be similar to a plane for scene display. The plane mode is best used when the scene is relatively small, such as the panorama of the community, the display of the building or the large equipment such as the oil field derrick.
Field angle mode
- FOV Mode: The scene camera angle setting supports horizontal or vertical, two viewport sizing modes.
Camera angle of view (degrees)
The combo box to the right of Camera Angle of View (degrees) sets the tilt angle of the camera in the current scene, which can be adjusted by holding down the mouse wheel and scrolling.
Terrain Scale Factor
The combo box to the right of the Terrain Scale Factor "is used to set the vertical exaggeration of the Terrain Data in the current scene.
Operation: The user can directly enter the appropriate value in the text box. The value of the Terrain Scale Factor is in times, which is the vertical magnification of the Terrain Data.
When the Terrain Scale Factor "is set to 1, it indicates that the Terrain Data is not in the original state of scaling; when a value greater than 1 is set, it indicates that the vertical scale of the terrain is enlarged, that is, the undulation of the terrain is exaggerated, so as to display the terrain conditions of the simulated earth surface more intuitively.
Note: If the user needs to perform terrain visibility or Viewshed Analysis in 3D Scene, the analysis can be performed only when the "Terrain Scale Factor" is 1 to ensure that the results are correct.
The numb of Layers that can be Select
Lets you set the number of layers that can be selected in the current scene. The number of layers that can be displayed in the scene is 2 ^ n (n is the value of the number of layers that can be selected), that is, if the number of layers that can be selected is set to 8, the number of layers that can be selected in the scene is 256. It is worth noting that if there are more than 2 ^ n layers in the scene, the extra layers will not be selected.
