When you operate in the scene, you need a specific perspective to fully view the objects in the scene, such as looking up at a building on the ground, or looking down at a section of underground pipeline. The tilt angle of the camera in the scene can be adjusted by holding down the mouse wheel to scroll.
The SuperMap scene defaults to normal viewing mode, which rotates a point in the scene (the center of the screen) around a line parallel to the X axis that passes through the point on the Z axis (the point where the earth's surface intersects the Z axis).
In the actual operation process, you can press and hold the mouse wheel while dragging the mouse up and down to make the picture in the scene move in the range of 0-90 degrees along the center point of the screen. When the camera angle of view is adjusted, the longitude and latitude coordinates of the center point of the screen are unchanged from the adjustment.
Camera Angle on the Scene Properties panel, which lets you adjust the camera angle range of the scene.

FOV Mode: The scene camera angle setting supports landscape or portrait, two viewport sizing modes.
Camera viewing angle: The camera viewing angle is mainly used to control the viewing angle range of the display screen. The smaller the viewing angle is, the smaller the display window range is, and the clearer the distant view is. The larger the camera viewing angle is, the larger the display window range is, but the more blurred the distant view is.
Here, the user can select several default reference values of the system, or manually set the required values, but the values should be controlled between 0 degrees and 180 degrees, excluding 0 degrees and 180 degrees.
