OpenGL for Windows

A wide range of functions

OpenGL, also known as "Open Graphics Library", provides developers with a wide range of functions to render 2D or 3D graphics. OpenGL is a standard specification that determines the output for each command. Although it is most well-known as an API or Application Programming Interface, it is not itself a specification.

Introduction to OpenGL

OpenGL is designed to interact with a system’s Graphics Processing Unit (or GPU) to produce real-time graphics rendering. Because it is cross-platform, OpenGL is often used as the primary graphics library for 3D games. This makes porting easier. OpenGL is also used by CAD programs like AutoCAD and Blender.

Many GPUs, integrated and dedicated, are optimized for OpenGL. It is supported by almost all modern systems. While most systems come pre-installed with the software, older versions of the software may require the latest GPU drivers. To maximize OpenGL's capabilities, users are advised to keep their drivers current.

OpenGL's greatest selling point is its accessibility. OpenGL's support for extensions supports this claim. GPU manufacturers can use extensions in order to implement rendering techniques not covered by OpenGL's specifications.

OpenGL's broad platform support makes it a great choice for game developers working with cross-platform rendering. However, it is not easy to learn and requires extensive study to render images from scratch. Despite its extensive library and support for extensions, it is still one of the most accessible graphics libraries.
