What is OpenGL in the video card?

OpenGL (All-write open Graphics Library) is a specification that defines a programming interface across programming languages, Cross-platform, and is used for three-dimensional images (both two-dimensional and also). OpenGL is a professional graphics program interface, is a powerful, easy to invoke the underlying graphics library.

High performance graphics algorithm industry standard

Opengl™ is the most widely accepted 2d/3d graphics API in the industry field, which has spawned thousands of of excellent applications on various computer platforms and devices since its inception. Opengl™ is independent of the Windows operating system or other operating systems, and is also network transparent. In areas including CAD, content authoring, energy, entertainment, gaming development, manufacturing, pharmaceuticals, and virtual reality, opengl™ helps programmers develop high-performance, high-impact graphics-processing software on hardware devices such as PCs, workstations, supercomputers, and more.

The predecessor of OpenGL is the iris GL developed by SGI Company for its graphics workstation. Iris GL is an industry-standard 3D graphics software interface that is powerful but poorly ported, so the SGI company developed OpenGL based on the Iris GL. OpenGL's English full name is "Open Graphics Library", as the name implies, OpenGL is "open graphics program interface." Although DirectX is a complete leader in the home market, OpenGL is not a substitute for high-end graphics in the professional field.
