Fog Term used to describe the blending of an object using a fixed color as objects are made to appear more distant from the viewer. Frame Buffer The portion of the memory buffer on the graphics card used to store the image being displayed. All rendering processes have been accomplished by 127 this stage and this buffer contains only a one-to-one relationship of the data 127 this stage and this buffer contains only a one-to-one relationship of the data to be relayed to the display. Frames Per Second In terms of 3D graphics, refers to the rate at which the graphic processor can render new screens per second. Higher rates equals better, more naturalistic performance for such things as games set in a 3D environment. Sometimes abbreviated to “fps.” Gamma Sometimes confused with brightness, gamma actually refers to the correction that is applied to any display device in order to produce more gradual increases or decreases in the perceived brightness for that device. A change in gamma produces a non-linear change in the color curve, ensuring that perceived changes in color and intensity are consistently applied. Gouraud Shading A shading method used to produce a smooth lighting effect across a 3D object. A specific color is used at each vertex of a triangle or polygon and interpolated across the entire face. HDCP HDCP is an acronym for “High-Bandwidth Digital Copy Protection.” It is a form of digital rights management designed to protect copyright of signals being transported across DVI or HDMI™ connections. Several international regulatory bodies have recommended its incorporation into high-definition display and playback devices. HDMI™ HDMI™ is an acronym for “High Definition Multimedia Interface.” It is a 19-pin connector used for transferring combined digital audio and video. HDMI™ supports standard, enhanced, and high-definition digital video signals, and is designed for use with VCRs, DVD players, personal 128 computers, and set-top boxes. A DVI adapter can be used to transfer the 128 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. HDTV Acronym for “High Definition Television,” a format that produces much greater picture quality than a standard television, and in a wide-screen format that matches that of a movie theater screen. The two most popular formats are 1080i and 720p, where the number represents how many horizontal scan lines they have, and the following letter represents whether the picture is interlaced, or the product of progressive scanning technology. Interlaced displays paint the odd-numbered scan lines and then the even- numbered lines to produce a picture, whereas progressive scan paints all of the scan lines at once. Both formats use an aspect ratio of 16:9. In contrast, standard North American television signals are displayed using 480 interlaced (480i) scan lines with a more square aspect ratio of 4:3. 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 129 of the 3D rendering process, making it a major performance bottleneck. 129 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.
