OpenGL (Open Graphics Library) is a professional graphical program interface that defines a cross-programming language and cross-platform programming interface specification. It is used for 3D images (also available in 2D) and is a powerful, easy-to-call underlying graphics library.
OpenGLTM is the industry's most widely accepted 2D/3D graphics API, and since its inception has spawned thousands of great applications on a variety of computer platforms and devices. OpenGLTM is independent of the Windows operating system or other operating systems and is also network transparent. In industries including CAD, content creation, energy, entertainment, game development, manufacturing, pharmaceuticals, and virtual reality, OpenGLTM helps programmers achieve high performance on PCs, workstations, supercomputers and other hardware devices. The development of high visual performance graphics processing software for impact.
OpenGL brings people into the world of 3D graphicsWe live in a three-dimensional world full of three-dimensional objects. In order for computers to accurately reproduce these objects, we must be able to depict these objects in three dimensions. We live in a world full of information. Whether we can understand and apply this information as soon as possible will directly affect the success or failure of our career, so we need to express this information in the most direct form.
The development of computer graphics in recent years has led to the formation of three-dimensional representation techniques that enable us to reproduce objects in the three-dimensional world and to represent complex information in three-dimensional shapes. This technique is VisualizaTIon. Visualization technology enables people to directly manipulate information with shapes and communicate directly with computers in a three-dimensional graphics world. This technology has united the power of people and machines in an intuitive and natural way. This revolutionary change will undoubtedly greatly improve people's work efficiency. Visualization gives people the ability to simulate, three-dimensional, and interact in real time, so that people can use the previously unimaginable means to capture information or use their creative thinking in the world of three-dimensional graphics. Mechanical engineers can liberate directly into the 3D world from a two-dimensional plan, and quickly get a 3D mechanical part model of their own design. The doctor can analyze the patient's lesion from the patient's three-dimensional scan image. Military commanders can face the battlefield shape generated by three-dimensional graphics technology, command realistic three-dimensional aircraft, warships, tanks to enter the target and analyze the effects of the combat plan.
What is even more amazing is the virtual reality technology that is currently being developed, which enables people to enter a three-dimensional, multimedia virtual world where people can travel through ancient castles and travel to the space of Haohan. All of this depends on the development of computer graphics and computer visualization technology. People's research on computer visualization technology has gone through a long process, and many visualization tools have been formed. Among them, SGI's GL 3D graphics library is outstanding, easy to use and powerful. The 3D application software developed by GL is very popular among many professional technicians. These 3D applications have been involved in architecture, product design, medicine, earth science, fluid mechanics and other fields. With the continuous development of computer technology, GL has further developed into OpenGL. OpenGL has been considered as the standard for high-performance graphics and interactive view processing. Currently, it includes ATT UNIX Software Lab, IBM, DEC, Sun, Several companies in the computer market, including HP, Microsoft, and SGI, have adopted the OpenGL graphics standard.
It is worth mentioning that, because Microsoft provides OpenGL graphics standards in Windows NT, OpenGL will be widely used in microcomputers, especially the introduction of OpenGL 3D graphics accelerator cards and microcomputer graphics workstations. People can implement 3D graphics applications on PCs. Such as CAD design, simulation, 3D games, etc., to make it easier and more convenient to use OpenGL and its application software to build your own 3D graphics world.
