Rendering in computer drawing refers to the process of generating images from models with software. Model is a description of three-dimensional objects with strictly defined language or data structure, including geometry, viewpoint, texture and illumination information.
Rendering is to make a model in a three-dimensional scene according to the set environment, lighting, materials and rendering parameters. The process of projecting a two-dimensional image into a digital image.

Universal rendering software
1、Renderman
RenderMan is a set of computer image rendering specifications based on the famous REYES rendering engine, and all renderers that meet this specification are called Renderman compatible renderers.
It was developed by the famous animation company Pixar. Renderman was originally an internal plug-in for Pixar, but it was released later. In today's high-end fields such as animated films and special effects, a renderer compatible with renderMan is an essential rendering solution. It is said that almost all special effects in Hollywood will be rendered by renderman. Another high-end solution is the mental ray renderer, which is also movie-level.
2. Spiritual rays
The famous German renderer mental ray is a professional 3D rendering engine, which is specially used for film and television rendering. It can generate high-quality realistic images. Mental Ray is a movie-level renderer comparable to Render Man. It has been widely used and recognized in the film field. In Hollywood, Mental Ray also participated in many movies.
3. Arnold Arnold renderer
Arnold renderer is an advanced, cross-platform, film-level rendering engine based on physical algorithms, which is used as the main renderer by more and more Hollywood studios. There are Maya rendering plug-ins and C4D rendering plug-ins.
4. Brazilian renderer
Brazilian renderer is different from the above, it faces the fields of industry, shipping, jewelry design, drawing and multimedia. It has powerful functions such as refraction and reflection of ray tracing, global illumination and defocusing, and the rendering effect is extremely powerful.
5. Final rendering
This is also the German renderer. Its rendering speed is very fast and the effect is very high, which is very suitable for the commercial market. FinalRender also provides the function of cartoon rendering simulation, which can be said to be an all-round renderer. Compared with other renderers, there are more settings, which may be difficult to understand at first.
6、VRay
VRay is amateur compared with other renderers, but the rendering effect is not inferior to other renderers. VR is characterized by its high speed and is not difficult to learn. Because its parameter adjustment is small and simple, many people who have no foundation will choose it.
3DMAX+VRAY or SketchUp+VRAY are widely used in construction, interior decoration, advertising and other industries.
