designed for use with VCRs, DVD players, personal computers, and set-top boxes.
A DVI adapter can be used to transfer the video signal to an HDMI-capable display,
although audio must be transferred from a different route, as DVI output does
not support audio.
Hue
Refers to a specific color within the visible spectrum of light, defined by its
dominant wavelength. A light wave with a central tendency within the range of
565-590 nm is visible as yellow. In the standard RGB color space used by most
computer displays, hue refers to a coordinate of the color as described by its red,
green, and blue values, minus any additional brightness or saturation values for
that color.
HydraVision
HydraVision is ATI's multi-monitor management software, enabling users to
manage the display of multiple windows and applications across two or more
adjacent monitors. It also includes a range of productivity features designed to
effectively manage applications in this environment.
HyperZ™ HD
HyperZ HD includes a number of different technologies aimed at optimizing
memory-bandwidth efficiency, particularly with respect to Z-buffer operations.
The Z-Buffer, sometimes also called the Depth Buffer, stores information used to
determine the placement of objects in a 3D environment with respect to the
viewpoint of the observer. Reading and updating this buffer typically consumes
more memory than any other part of the 3D rendering process, making it a major
performance bottleneck. HyperZ HD technology reduces the memory bandwidth
consumed by the Z-Buffer, thereby increasing performance while also making
the 3D environment more realistic.
Keyframe Interpolation
This feature is also known as "morphing." In an animation, a start and end point
are picked as the key frames. In a 3D rendering, the start point could have a
character with a neutral expression, and the end point could have that same
character smiling. Additional frames are interpolated (inserted) between the two
keyframes in order that morphs (transforms) the image so that there is a smooth
transition between the key frames.
KTX Buffer Region Extension
This OpenGL programming term refers to a feature that rapidly updates portions
of the display of 3D modelling applications that change very quickly, or have been
moved or occluded. It does this by optimizing the storage of buffer regions in the
graphics card's memory buffer. Other applications are typically not adversely
affected when this is enabled.
Lighting
In 3D computer graphics, refers to aspects and quality of the virtual light source
being used to make an object visible. Lighting can strongly affect the "mood" of a
scene. For example, a "harsh" light could be a bare lightbulb that is glaringly
bright on the objects closest to it while casting strong shadows in the background.
A "softer" light would be more diffuse and not cast shadows, such as you would
get outdoors on a typical overcast day.
Mipmapping
The most memory-intensive aspect of 3D graphics are the textures that give an
object its realism (like wood, marble, leather, and cloth). Because objects in real
life become less detailed as they move farther away from the viewer, 3D
