What is rendering and what are its purposes in digital art
Rendering is a process of generating the visual, or graphical, representation of 3D models and scenes composed of various objects. Rendering is often utilized in animations, games, and other real time graphics. Rendering is one of the important parts in digital art. From the author’s point of view, it is a process of recreating the scene and therefore rendering is used in 3D computer graphics (CG), architectural (AR), digital product design, etc. In short, rendering is used in other graphic arts as well.
The concept of rendering itself can be categorized into two main types such as geometric and rasterization. Geometric is one that applies to the process of creating 3D models; rasterization applies to the representation of three-dimensional objects. Within each type there are many ways of rendering such as software, hardware, tools and so on.

The different types of rendering and the effects they create
Rendering is a process of creating a visual image from 3D models. The visual image could be anything that the computer’s inbuilt drawing software can output. These images are very realistic, such as those used in TV shows and computer games. In general, the realistic images are made using pixel art and is generally easier to comprehend. However, the image can also be made using rasterization that is generally more difficult to understand and comprehend. The difference between pixel art and rasterization is that pixel art is created by using a limited number of colours with no gradation in brightness, while rasterization uses imagery with millions of colours and can produce images that are not realistic but are more realistic than before. Rasterization is commonly used in applications such as PhotoShop, Gimp or Photoshop where images need to look more realistic than they usually do.[…][…]
##Rendering is the process of converting 3D Models from a CAD (Computer-Aided Design) into 2D images with realistic lighting effects, shadows and reflections. In Computers, there are two types of rendering. Pixel Art is made by using a limited number of colours with no gradation in brightness. Rasterization is the process where there are millions of colours and can produce images that are not realistic but are more realistic than before.[…][…]
Most computer animations are made using pixel art, where the model is created using by using a limited numbers of colours (usually 256) with no gradation in brightness, and often with other restrictions. Pixel art can also be created using rasterization where the image is made with millions of colours and can produce images that are not realistic but are more realistic than before.[…][…]
