A fragment is a computer graphics term for all of the data necessary needed to generate a pixel in the frame buffer. This may include Computer graphics (CG) is the field of visual computing, where one utilizes computers both to generate visual images synthetically and to integrate or alter visual and spatial information sampled from the real world. ... A pixel (pix, 1932 abbreviation of pictures, coined by Variety headline writers + element) is one of the many tiny dots that make up the representation of a picture in a computers memory. ... The framebuffer is a part of RAM in a computer allocated to hold the graphics information for one frame or picture. ...
It can be thought of as the data needed to shade the pixel, plus the data needed to test whether the fragment survives to become a pixel (depth, alpha, stencil, scissor, window ID, etc.) Suppose the smiley face in the top left corner is an RGB bitmap image. ... Z-buffer data In computer graphics, z-buffering is the management of image depth coordinates in three-dimensional (3-D) graphics, usually done in hardware, sometimes in software. ... Spherical texture mapping Texture mapping is a method of adding realism to a computer-generated graphic. ... Stencil buffer is an extra buffer in addition to the color buffer and depth buffer found in OpenGL and Direct3D. The buffer is per pixel, and works on integer values. ... In computer graphics, alpha compositing is often useful to render image elements in separate passes, and then combine the resulting multiple 2D images into a single, final image in a process called compositing. ... To meet Wikipedias quality standards and make it easier to understand, this article or section may require cleanup. ...
Forest connectivity and whether fragmentation is from human or natural causes.
The Causes of Forest Fragmentation map layers were derived from NLCD by the U.S. Environmental Protection Agency and the U.S. Geological Survey (USGS).
The layers are the first to identify sources of forest fragmentation, and may be useful for decision makers in identifying forest areas for protection or restoration.
Nevertheless, fragmentation is still a cause for concern for those who design and implement filesystems, as well as for end users.
A fragment is a fraction of a block (for example, 1/8th of a block).
Fragmentslead to more efficient use of space when there is a large number of small files on a volume, at the cost of more complicated logic in the filesystem's implementation.
