Open Graphics Library for Embedded Systems (OpenGL ES) is an Application Programming Interface (API) to graphics hardware. OpenGL ES 3.2 API supports 2D/3D graphics rendering and is backward compatible with previous OpenGL revisions (for example 3.1, 3.0, 2.0, or 1.1).

The entire information set of OpenGL ES2 can be located at Khronos.org, while the specification can be located at https://www.khronos.org/registry/OpenGL/specs/es/3.2/es_spec_3.2.pdf
