This is a set of cross-platform wrappers over the OpenGL ES 2.0 API.
Please note that OpenGL ES context creation and management is outside of the scope of this library.
This library wraps all OpenGL types, constants, and functions into the GL namespace. For example, to call the glClear function you may write the following piece of code:
GL::clear(GL::COLOR_BUFFER_BIT | GL::DEPTH_BUFFER_BIT);
In debug builds, all calls to OpenGL functions are checked with glError calls. Any detected problems are reported to std::clog.
Currently, there are three wrappers available:
-
The normal wrapper is for use in all projects except for those built using the Qt library. On systems with OpenGL ES 2.0 support this wrapper invokes OpenGL ES functions directly. On desktop systems (Windows, Unix, OSX) OpenGL ES calls are emulated through the full version of OpenGL (with the help of the OpenGL Extension Wrangler library).
-
The qt wrapper is intended for use in projects built with the Qt library (version 4.8 or later). OpenGL calls are made through the QGLFunctions class.
-
At last, there is the dummy wrapper with all functions implemented as empty stubs. This wrapper is useful for compilation on platforms without OpenGL support and as a skeleton for new wrappers.
Before usage, wrappers should be initialized by calling the GL::init() method.
This library is not intended to be built directly. Instead it is supposed to be included into projects using the Yip.
Use the import gles2 directive in your Yipfile to use this library.
