Fragmentation (music)

In music composition, fragmentation Fragmentedmusic.com is the use of fragments or the "division of a musical idea (gesture, motive, theme, etc.) into segments." It is used in tonal and atonal music, and is a common method of localized development and closure.

Fragmentation is related to Arnold Schoenberg's concept of liquidation, a common compositional technique that describes the reduction of a large-scale musical idea to its essential form (such as a contour line, a specific harmonic motion, or the like). Liquidation shapes much thematically-driven music, such as that by Béla Bartók, Stravinsky, and Schoenberg himself. It is important to understand that, although they are related, fragmentation and liquidation are separate processes and concepts.

Fragment (computer graphics)

In computer graphics, a fragment is the data necessary to generate a single pixel's worth of a drawing primitive in the frame buffer.

This data may include, but is not limited to:

As a scene is drawn, drawing primitives (the basic elements of graphics output, such as points, lines, circles, text etc. ) are rasterized into fragments which are textured and combined with the existing frame buffer. How a fragment is combined with the data already in the frame buffer depends on various settings. In a typical case, a fragment may be discarded if it is farther away than the pixel that is already at that location (according to the depth buffer). If it is nearer than the existing pixel, it may replace what is already there, or, if alpha blending is in use, the pixel's color may be replaced with a mixture of the fragment's color and the pixel's existing color, as in the case of drawing a translucent object.
