Introduction of camera position

The camera position is the spatial position of the camera relative to the object. Some people call it a shooting point. People usually use azimuth, height and distance to indicate the position of the camera. Some people are used to using the two dimensions of shooting angle and distance to grasp. At this time, the horizontal angle in the shooting angle is equivalent to the orientation of the former, and the vertical angle is equivalent to the height. Or use the scene and shooting angle (including vertical angle and horizontal angle) to represent the camera position.
