In past version of Windows rendered desktop elements as a series of bitmapped or raster, graphics. The digital representation of an image using several numbers of colored dots called pixels. Windows Vista displays all desktop elements as vector graphics. It is use mathematical expressions to define the curves, lines of an image. All graphics were rendered by the system main CPU in previous part of Windows.
The graphics can eat up processing time and low operation of your whole computer. The latest Windows Presentation Foundation graphics model, this is performed by a individual Graphics Processing Unit contained on your system video card. The Dedicated GPU renders graphics faster than a shared CPU and frees up the CPU to run system applications. Vista Aero Interface is created by Pixel Shading technology and this function that calculates visual effects on a per-pixels basis.
It can create a high ordinary amount of surface details and enables the effect of the Vista Aero Interface. In collection of pixel is called as object. The individual screen elements can then be layered on top of each other and moved around the desktop independently without the tearing and blending common with bit mapped images.
