What is 3D computer graphics?

3D Computer graphics is a picture that uses computer software to create objects in a virtual three -dimensional (3D) space. This is, unlike two -dimensional (2D) images that exist only as flat images that can use visual tricks such as perspective to create a three -dimension illusion. 3D computer graphics are usually created by artists by creating a 3D model consisting of a wire model and polygons, which is then usually textured and lit before rendering. This type of images was originally created only through mathematical algorithms and equations. Modern 3D images, however, are produced using a software that represents an artist graphical user interface (GUI), allowing you to create 3D computer graphics without direct interaction to be the artist and mathematical properties of the image.

Creating 3D computer graphics usually begins with modeling an object that appears in the final picture. For example, the cube can be created relatively simple and the same wayKO All 3D frames consist of wired model and polygons. The wire model is the basic shape of an object consisting of different points and lines connecting these points. This can be easily introduced what an object would look like if it was made of chicken wire.

Polygons are shapes, also called faces that fill the wire model and create solid 3D computer graphics. Using an example of the cube, the corners would be made of wire model points and lines, while the real sides of the cube would be polygons or faces. This form is then textured, which means that the polygons are applied to the polygons to give it a look for a and only color. Such textures may include: simple graphics such as illustration of grain wood; Mapping of impacts that would provide a sense of depth of folds in grain; and reflective maps that provide shaving to textures such as glass and metal.

Once the object is modeled and textured,Then you can add lighting that gives shadows and highlight objects. This scene is then portrayed to create 3D computer graphics. During plotting, various elements in the scene are stored and compiled to create a image file that can be used to share and view the 3D computer graphics scene. Many professional studies have computers used only for rendering, as this process can take a long time and often requires a large amount of processing.
