Find a detailed explanation of the virtual camera.

A virtual camera is a "camera" set by animation software in a computer. It plays a role in expressing opinions in animation, which is equivalent to a camera in the traditional sense. Virtual cameras are completely different from physical cameras, but their functions are very similar. Physical cameras shoot real people or actually built scenes. The virtual camera can shoot the model built in the three-dimensional software, which can realize infinite possibilities. There is only one icon, and it also has parameters such as lens, focal length, focus, aperture and depth of field, which can realize "push, pull, shake, move, follow, swing, rise, fall and comprehensive motion", and can achieve shooting effects that are difficult or even impossible for physical cameras such as wall-penetrating, keyhole and human body. The parameters that need to be adjusted from pulling the lens on the earth's surface to the space physical camera are distributed on the fuselage and need manual operation. The parameters of the virtual camera are buttons or digital input fields integrated on the panel. Only the operator needs to input parameters or drag the mouse, and sometimes several key frames can determine the motion path of the camera. Physical cameras need stabilizers or motion control systems in actual shooting. Even if the picture jitter is inevitable, the shooting of virtual cameras can achieve absolute stability. A high-precision physical camera often loses its target when shooting a "follow-up" lens, while a virtual camera can completely lock the target without losing the content source:/s/blog _ 4D2f1df 90100rsg6.html.
