OpenGL (Open Graphics Library) es una especificación estándar que define una API multilenguaje y multiplataforma para escribir aplicaciones que produzcan gráficos 2D y 3D. La interfaz consiste en más de 250 funciones diferentes que pueden usarse para dibujar escenas tridimensionales complejas a partir de primitivas geométricas simples, tales como puntos, líneas y triángulos. Fue desarrollada originalmente por Silicon Graphics Inc. (SGI) en 1992 y se usa ampliamente en CAD, realidad virtual, representación científica, visualización de información y simulación de vuelo. También se usa en desarrollo de videojuegos, donde compite con Direct3D en plataformas Microsoft Windows.
