Usage Instructions
When operating within a scene, specific perspectives are required to comprehensively view objects in the scene, such as looking up at a building from the ground or looking down at a section of underground pipeline.
The software displays the scene in the default perspective mode, which rotates a point (the screen center point) around a line parallel to the X-axis passing through that point on the Z-axis (the intersection point of the Earth's surface and the Z-axis). During scene navigation, you can hold the mouse wheel and drag up or down to move the scene within a 0-90 degree range around the screen center point.
You can adjust the scene camera perspective by modifying the field of view mode and camera perspective. Note that when adjusting the camera perspective, the latitude and longitude coordinates of the screen center point remain unchanged.
Function Entry
- Scene Tab -> Properties Group -> Scene Properties Button -> Scene Properties Panel -> Basic Module -> Field of View Mode/Camera Perspective
Operation Steps
- Open or create a scene, click the Scene Tab -> Properties Group -> Scene Properties Button to open the Scene Properties panel. Adjust the Field of View Mode and Camera Perspective in the Basic module.
- Field of View Mode: Used to adjust the range of the scene observable by the camera. Options include Horizontal and Vertical.
- Horizontal: This mode determines how wide a scene can be viewed. The horizontal field of view is the angle between the two lines extending from the center of the lens to the left and right edges of the imaging frame.
- Vertical: This mode determines how high a scene can be viewed. The vertical field of view is the angle between the two lines extending from the center of the lens to the top and bottom edges of the imaging frame.
- Camera Perspective: Used to control the range of the scene camera perspective, with a value range of (0,180) in degrees. A smaller perspective results in a relatively smaller display window but clearer distant views, while a larger camera perspective results in a relatively larger display window but blurrier distant views.
- Field of View Mode: Used to adjust the range of the scene observable by the camera. Options include Horizontal and Vertical.
