opengles_spec_2_0

This document outlines the OpenGL ES 2.0 specification. OpenGL ES 2.0 implements the Common profile only. The fixed point (signed 16.16) data type is supported for vertex attribute arrays only. Shader uniform variables and command parameters no longer support fixed point in order to simplify the API and also because the fixed point variants do not offer any additional performance. The OpenGL ES 2.0 pipeline is described in the same order as in the OpenGL specification. The specification lists supported commands and state, and calls out commands and state that are part of the full (desktop) OpenGL specification but not part of the OpenGL ES 2.0 specification. This specification is not a standalone document describing the detailed behavior of the rendering pipeline subset and API. Instead, it provides a concise description of the differences between a full OpenGL renderer and the OpenGL ES renderer. This document is defined relative to the OpenGL 2.0 specification. This document specifies the OpenGL ES renderer. A companion document defines one or more bindings to window system/OS platform combinations analogous to the GLX, WGL, and AGL specifications. 1
