A bird's eye view is different from an effect view. \x0d\ bird's eye view: \x0d\ 1: a map drawn by high-point perspective method. \x0d\2: An image of an area from the air. \x0d\ renderings \x0d\ express the required and expected effects of the work through media such as pictures. In modern times, it is a high simulation virtual picture that simulates the real environment through computer three-dimensional simulation software technology. In the subdivision fields such as architecture and industry, the main function of renderings is to make plane drawings three-dimensional and simulated, and to check the subtle defects of design schemes or review the modification of project schemes through the production of high simulation.
