Pixel Tapestry™ II
Pixel Tapestry™ II uses four parallel, highly optimized rendering
pipelines, each capable of handling two textures simultaneously. It
provides advanced texturing, making 3D surfaces look even more detailed
and realistic.
Refresh Rate
Also referred to as “vertical refresh rate.” This is the rate at which a monitor
or television can redraw the screen from top to bottom. NTSC television
systems have a refresh rate of approximately 60 Hz whereas computer
displays typically have refresh rates of 75 Hz or more. At refresh rates of
70 Hz and lower, screen flicker is often noticeable.
Rendering
Rendering refers to the final drawing stages where the 2D image that
appears on a display is derived from its 3D descriptions. What appears on
the display may look three dimensional, but it is really just a 2D grid of
pixels designed to appear that way.
Resolution
The resolution of any display is the number of pixels that can be depicted
on screen as specified by the number of horizontal rows against the number
of vertical columns. The default VGA resolution of many video cards is
capable of displaying 640 rows of pixels by 480 columns. The typical
resolution of current displays is set to higher values, such as 1024x768
(XGA), 1280x1024 (SXGA), or 1600x1200 (UXGA).
Saturation
Refers to the intensity of a specific hue (color). A highly saturated hue is
vivid and intense, whereas a less saturated hue appears more grey. A
completely unsaturated color is grey. In terms of the RGB color model, a
fully saturated color exists when you have 100% brightness in one of the
three channels (say, red) and 0% in the two others (green and blue).
Conversely, a fully desaturated color is one where all of the color values are
the same. Saturation can therefore be thought of as the relative difference
between the values of the channels.
