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.
Shadow Mask
In CRT monitors, the shadow mask is a metal plate full of tiny holes that is
attached to the inside of the glass screen. It focuses the beams from the
electron guns at the back of the CRT. The distance between these holes is
called the dot pitch.
SmartShader™ HD
SmartShader™ HD contains advanced vertex and pixel-shading
capabilities. A shader is a small program that runs on the GPU and
describes how an image should be rendered. Vertex shaders manipulate the
individual polygons that make up 3D objects, and pixel shaders operate on
the individual pixels that fill in these polygons to create a visible image.
SmartShader™ HD is designed to alleviate the resource constraints of
earlier shader hardware, paving the way for more complex, detailed, and
realistic shader effects in applications requiring high-performance 3D
rendering.
SmoothVision™ HD
SmoothVision™ HD incorporates improved anti-aliasing, anisotropic
filtering and 3Dc™ compression features designed to further enhance
image quality. Anti-aliasing performance is improved, providing better
overall detail and image quality. The enhanced anisotropic filtering ensures
sharper and clearer pictures at higher frame rates, and the new 3Dc™
compression technology makes it possible to display higher polygon counts
for 3D rendered objects.
