What is the OpenGL® Renderer?

OpenGL® plotter is a software application, library or abstract programming interface (API) that is designed to take over the program mathematical, geometric and texture information and display on the output device. The OpenGL® rendering duty is to bridge the gap between the information on the three -dimensional (3D) object, which is stored as coordinates, vectors and other numbers and convert it to an image by lighting, textures and the correct view. OpenGL® includes its own implementation of rendering, but it can be rewritten either to improve existing algorithms or to support functions that could otherwise be supported by certain hardware configurations. Many programs that use 3D graphics often include the option to choose the type of renderrer used, depending on what is supported by hardware. This is often observed on mobile devices or own displays that support unique features such as 3D display. By customizing the application portion of the applicationCE can be focused on limitation or special output medium capabilities to run smoothly and display in the desired way.

OpenGL® application applications is to help streamline the functions to work faster or other than the default rendering. This can be seen in some video games in which you need to further expand specific functions and functions that are rarely used in programs that do not play to achieve high images and consistent performance. During the development of the game you can also use your own renderinger to provide a tuning environment when other rendering methods cause graphic problems.

There are certain cases - for example, in the area of ​​security, transport or other embedded systems-, in which the software could be written using OpenGL® to display information in real time, but this software may not be launched on the system that has a graphicalcard. One example is the aircraft display in which the software is developed and tested on the desktop computer system. In this case, the OpenGL® plotter can be used to ensure that the software uses standard features, none of the calls is done due to the lack of graphic hardware. This is a way to use standard programming libraries anywhere through revised software emulation.
