A perspective rendering is a two-dimensional artistic representation that gives the illusion of three-dimensional space. It is commonly used in architecture, interior design, and advertising to showcase the appearance of buildings or spaces. A waterfront teahouse refers to a traditional Chinese teahouse situated by the river or sea, often with a serene and picturesque setting. The perspective rendering of such a teahouse would depict its structure, surroundings, and the natural environment in a visually engaging manner.
