In addition, it provides a software abstraction of graphics devices by rendering them onto a local area 2D memory bitmap. The library is composed of the necessary state-setting steps, utility routines for managing resources and access to other functions in the system. OpenGL interface functions with the ‘ client- side’ API library in basic implementations, which does not include hardware-specific code.
In addition, the architecture of OpenGL takes advantage of a layered design that makes it easier to extend it in the future without breaking support for older hardware devices.
The API makes it easier to use OpenGL functions by removing cross-platform issues such as different graphics hardware capabilities, different windowing systems and operating system graphics device drivers.
