Windows Process Description:

The atioglxx.dll module is the ATI OpenGL driver. It has influential to the development of 3D accelerators, while promoting a base level of functionality that is now expected in all consumer hardware. Open GL also provides software developers with various primitives, modeling transformations, display lists, anti-aliasing, lighting and texturing and blending. The atioglxx.dll module rasterises lines, points and polygons.

The atioglxx.dll module contains a standard specification that defines a multi-language multi-platform API for writing 2D and 3D computer graphics applications. It consists of over 250 different function calls, which allow the user to draw detailed three-dimensional scenes from just simple primitives. The atioglxx.dll module is applied in many applications including, virtual reality, CAD, information visualization, scientific visualization and flight simulation. The atioglxx.dll module also competes with Direct3D in video games, running on Windows platforms.

The file atioglxx.dll has two functions, the first of which is to remove some of the complexity of interacting with various 3D accelerators, by offering the programmer a single API. The second function is to hide the differences between hardware platforms, by making it necessary for all implementations to fully support the OpenGL features.

Using the atioglxx.dll process, OpenGL is able to accept primitives like lines, points and polygons, to modify them to pixels. A graphics machine known as the OpenGL state machine performs this conversion. OpenGL either issue the graphics pipeline with primitives, or configures the way the pipeline should process these primitives.
