Why is it important to know about OpenGL?
OpenGL is an interface that allows us to access and control this pipeline. Technically, OpenGL is not itself a library but a standard interface specification. This allows individual hardware vendors (like NVIDIA and AMD) to implement their own drivers and libraries to give developers common access to their hardware.
What was the purpose of OpenGL 3.0 deprecation?
OpenGL 3.0 introduced a deprecation mechanism to simplify future revisions of the API. Certain features, marked as deprecated, could be completely disabled by requesting a forward-compatible context from the windowing system. OpenGL 3.0 features could still be accessed alongside these deprecated features, however, by requesting a full context.
How are the extensions defined in OpenGL Registry?
All extensions are collected in, and defined by, the OpenGL Registry. Each extension is associated with a short identifier, based on the name of the company which developed it. For example, Nvidia ‘s identifier is NV, which is part of the extension name GL_NV_half_float, the constant GL_HALF_FLOAT_NV, and the function glVertex2hNV ().
