Overview
~~~~~~~~

This class is an abstraction of some OpenGL functionality. eepp has 4 different rendering pipelines: OpenGL 2, OpenGL 3, OpenGL 3 Core Profile and OpenGL ES 2. This abstraction is to encapsulate this pipelines. eepp implements its own state machine to simulate fixed-pipeline commands with OpenGL 3 and OpenGL ES 2. Most of the commands can be found in the OpenGL documentation. This is only useful for advanced users that want some control of the OpenGL pipeline. It's mostly used internally by the engine. :ref:`More...<details-class_e_e_1_1_graphics_1_1_renderer>`

Detailed Documentation
~~~~~~~~~~~~~~~~~~~~~~

This class is an abstraction of some OpenGL functionality. eepp has 4 different rendering pipelines: OpenGL 2, OpenGL 3, OpenGL 3 Core Profile and OpenGL ES 2. This abstraction is to encapsulate this pipelines. eepp implements its own state machine to simulate fixed-pipeline commands with OpenGL 3 and OpenGL ES 2. Most of the commands can be found in the OpenGL documentation. This is only useful for advanced users that want some control of the OpenGL pipeline. It's mostly used internally by the engine.
