What is the OpenGL® ATI ™ driver?

The

Open Graphics Library® (OpenGL®) ATI ™ is a software interface developed by ATI ™ Technologies as a bridge between the hardware of their graphics card and the abstract programming interface (API) for the OpenGL® library. There are different drivers for each operating system and different drivers for different graphics card architectures that are sold. The OpenGL® ATI ™ driver is specially designed to make the best use of graphics hardware while maintaining an OpenGL® API. The controller includes its own OpenGL® extension, which can be used to access special functions or accelerated graphics card functions consistently within the OpenGL®. Not all ATI ™ graphics cards have their own OpenGL® ATI ™ controller, which means some share a common controller that can lead to problems when certain features are required to prevent hardware to support.

One of the bridge's important duty that the OpenGL® ATI ™ driver performs is access to the graphics card hardware directly viaAny hardware interface used to communicate with the main computer system. This is beneficial to programmers because the manufacturer creates drivers as part of demanding specifications for best performance. In addition, ATI ™ cooperates with the architecture's inspection plate (ARB), which maintains the OpenGL® specification, so with the development of new hardware, OpenGL® can evolve at the same time and support can be implemented from both sides.

Operations, for example, use numbers with movable floating points, OpenGL® ATI ™ drivers move, and then the graphics card are treated with a graphics processing unit (GPU), which has special registers to make operations as quickly as possible without using any main performance of computers. Men of low -level operations dealing with fragments, peaks and matrix are in most cases passed directly to the GPU via the driver. This kind of functionality would be either impossible or inElmi unreliable if the driver was not present.

The whole graphic procedures can be optimized through hardware. For example, the OpenGL® ATI ™ driver can transmit information to the GPU so that anti-aliasing, mixing and multisampling can be done directly in the hardware. The controller also provides access to the temporary memory inside the card, so the texture or peak fields can be stored and operated in graphics hardware.

There are some complications when using the OpenGL® ATI ™ driver. There are so many hardware models of ATI ™ graphics cards that some drivers are shared and can cause compatibility problems with certain features. There are also some non -standard programming steps that might need to be carried out ati ™ can take their own optimization. Creating a program that is optimized for the ATI ™ graphics card can also mean creating a program that is not compatible with another card brand.
