OpenGL (Open Graphics Library) is the computer industry’s standard API for defining 2-D and 3-D graphic images. OpenGL allows new hardware innovations to be accessible through the API via the OpenGL extension mechanism. It is used in CAD (Computer-aided design), virtual reality, video games, and flight simulation.
This site contains the API and Extension registries for the OpenGL family APIs - OpenGL, OpenGL ES, and OpenGL SC. It includes API specifications; specifications of Khronos- and vendor-approved extensions; header files corresponding to the specifications; the XML API Registry defining each API; and related tools and scripts.
OpenGL.Net is a comprehensive C# binding for OpenGL, OpenGL ES, and related APIs. It provides strongly-typed, fully documented access to modern OpenGL functionality with automatic error checking, extension management, and cross-platform support.
