VECTORS The cross-product vector v × w is perpendicular to the plane formed by the vectors v and w. rules for generating graphics on printers and computer screens, and use vector concepts in drawing letters as well as pictures. Graphics files on your computer that end in .GIF or .JPG are raster files. Vector files (geometric files) are easier to modify than raster files. Raster files display faster than vector files, although the high speed of modern processors makes this a negligible difference to the ordi- nary computer user. Vector descriptions of images are used for computer identifi- cation of faces, for translating handwriting into computer text, for descriptions of protein structures, and for the location of tumors in medical CAT scans. online sources for further exploration Animations of vector operations Computer graphics Magnetic Resonance Imaging (medical visualization) Parachute vectors Vector properties Vectors in text ▲ ▼ ▲ VOLUME Volume describes the amount of space contained in a three-dimensional object. Almost every object we use has volume, due to having depth. Even a sheet of paper has volume, because it has thickness, although a very thin one. If an object, such as paper, does not have volume, then it could be stacked indefi- nitely without having any height. You can estimate the thickness of a sheet of Download 1.81 Mb.
