Divide the total viewing area into smaller and smaller rectangles until each small area is the projection of part of a single visible surface or no surface at all.ЗВУКИ ДЛЯ HLDJ ИЗ КС ГО Lecture - 26 Visible Surface Detection Department of Computer Sciences. Graphics – Spring (Lecture 23). Depth - Sort Algorithm. This depth - sort algorithm is sometimes called the painter’s algorithm because it mimics the way that oil painters usually work (painting the background before the foreground). u 2D computer graphics. n graphical user interfaces: Mac, Windows, X, n graphic design: posters, cereal packets, n typesetting: book publishing, report Depth sort algorithm.
