The effect diagram is to express the required and expected effect 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 sub-industries, such as architecture and industry, the main function of renderings is to make the plane drawings three-dimensional and simulated, and to check the subtle flaws in the design scheme or to scrutinize the modification of the project scheme through the production of high simulation. As a tool for architects to scrutinize designs, renderings are irreplaceable.

Subdivision of renderings:

Rendering is a broad word, but the most widely used fields can be roughly divided into architectural renderings, urban planning renderings, landscape environmental renderings, architectural interior renderings, mechanical processing renderings, product design renderings and so on. The coverage of simple words is unimaginable.

Differential function:

1, hand-painted, as the name implies, is a kind of decoration profile trained by designers through strokes for a long time. Hand-painting needs solid painting skills to make its design intention vivid.

2. Many designers pay more attention to computer renderings than hand drawing, but often in the practical skills of talking about the list, hand-drawn performance is far greater than computer renderings [1], which is also a manifestation of a designer's ability.

The most basic requirements of efficiency:

It should conform to the size of the thing itself, and it is not possible to change the size of the related model by using the effect for the sake of beauty. Such renderings can not only express the design, but also become a factor affecting the design.
