What is a rendering engine?
What is a rendering engine? Rendering engines represent different things in different industries.
For example, for people doing web applications, rendering engine means Gecko, KHTML / WebKit. All web browsers, email clients, e-readers, and other applications that need to display content based on a representative markup language require rendering engine.
For artists making games, rendering engine refers to the core components of some edited computer game systems or some interactive real-time graphics applications. The rendering engine category includes PC, mobile, PlayStation, Xbox, VR devices, etc.
For CG artists and 3D rendering, rendering engine has a different meaning.
Whether it is "Avatar", "Titanic" or "Iron Man", the success of these world-class blockbusters can not be separated from building models in 3D software, and then to visual effects, rendering the final image in the renderer, and post-production software in composition, editing, and other processes.
There are currently built-in rendering engines in popular 3D production software. Below we introduce several rendering engines that are currently mainstream in CG production,
V-Ray is applicable to SketchUp, 3ds Max, Maya, Unreal, Cinema 4D, Modo, etc.. V-Ray is a well-known renderer in the rendering software industry. It is designed and completed by Chaos Group. It has "ray tracing" and "global illumination" rendering software. It provides high-quality pictures in 3D modeling software and animation rendering for different fields.
From "Gravity" to the " Logan" and "Avengers", the blockbusters you see now basically have it in it. Arnold can perform huge scene file calculations with high accuracy. It tries to imitate the real world as much as possible without taking shortcuts, which is also related to the algorithm used to calculate images at the bottom.
Corona is suitable for 3ds Max and Cinema 4D. Corona Renderer is the latest photo-level renderer that can improve the rendering quality of pictures and simulate the most realistic texture. It is regarded as a rising artifact for the rising star. Because Corona Renderer in a similar way to Photoshop layers, it is very easy to get started.
The Redshift renderer's global light algorithm is similar to V-Ray, but also four algorithms, divided into PrimaryEngine and SecondaryEngine. And its HDRI lighting is very powerful, the light comes with soft shadows, and the built-in powerful rendering technology can help users complete the rendering of large scenes, making users render works better.
Octane is also a GPU-based renderer. First of all, its SSS and replacement functions are very good in comparison, the speed is also very fast, the light is soft, and the rendering looks comfortable, too. If the scenario is solved with PL, the efficiency is a bit problematic.
The production software and rendering engine used in the CG industry have their own advantages and disadvantages. It is most important to choose the one that suits you. What is a rendering engine? Hope this article can help you.
