Detailed Description

Low-level OpenGL Wrappers.

The ImFusion::GL namespace provides a collection of classes and functions to wrap the OpenGL API into more approachable and easier to manage C++ entities.

In order to use OpenGL you must first create and initialize an OpenGL context and load the OpenGL function entry points from the GPU driver. The easiest way to achieve this is to call GL::init(). Make sure to call GL::deinit() before exiting your application to properly release all OpenGL handles managed by ImFusionGL.

Error handling

The constructors of most classes in ImFusionGL will throw a std::runtime_error if they fail to create the underlying OpenGL resource (e.g. a texture or a buffer object). All other member functions are supposed to handle potential errors more gracefully and not throw unless this is explicitly documented.
