OpenGL® software creates computer graphics using programming to instruct a graphics engine to render 2D or 3D objects. It can be used for CAD, gaming, and creating digital models. Both 2D and 3D graphics are created through mathematics and polygons.
OpenGL® computer graphics are images displayed through the use of OpenGL® software rather than other types of computer imaging (CGI) programs. These are visualized through the use of computer coding much like developing computer software. Instead of using this coding to instruct a program how to operate, however, programming is used to instruct a graphics engine what and how to render various two-dimensional (2D) or three-dimensional (3D) objects. OpenGL® computer graphics have some advantages over other programs in that they can be used with multiple operating systems (OS) and various platforms.
There are a variety of settings in which OpenGL® computer graphics can be used, including creating computer-aided design (CAD) and video game programs. Different landscapes, scenes and objects can be created through the use of this type of software. For architectural or design purposes, OpenGL® computer graphics can be used to create digital models of buildings as demonstrations for a client or to create a digital mockup of a product. In game design, these types of graphics are often used to create scenes and objects that are easily reproduced by many different types of hardware and software.
Both two-dimensional, or 2D, and three-dimensional, or 3D graphics can be created through the use of OpenGL® software, and these images can then be easily rendered and displayed by computer systems. OpenGL® computer graphics are basically created through the use of computer programming, much like that used to create new software or to design and develop a website. The software then executes the code that has been written and, in doing so, generates different types of objects made up of lines and polygons. These types of OpenGL® computer graphics are developed through mathematics, as each point in an object is indicated in the code.
Points in space, also called vertices, and lines are used to create OpenGL® 2D computer graphics. A triangle, for example, can be created via code that points to three particular points, then tells the software to connect those points with lines to create a total shape. 3D graphics, however, are a bit more complex and require a lot of code to create. These objects are created as OpenGL® computer graphics through multiple shapes called polygons, which are connected together to form the surface of a 3D object. This is then structured through additional programming and can be manipulated in numerous ways through more code.
