German Quernheim,Maria Schreier76) horizontal rows. Individuals from the set of NXPIX by NYPIX pixels can be uniquely identified by a bracketed pair of integers; these are sometimes called a pixel vector (I, J), where 0 ⩽ I ⩽ NXPIX — 1 and 0 ⩽ J ⩽ NYPIX — 1, the vector specifying the position of the pixel in the I. column and J.

Betriebsstörungen und Warteschlangen able to draw line segments between pairs of points. To be strictly accurate, a . (or line for short) in two-dimensional space is not a finite segment, but stretches off to infinity in both directions, and so we need to introduce ways of representing a general point on such a line.

https://doi.org/10.1007/978-3-642-18531-1we need to make the equivalent linear transformations on three-dimensional space. As in the lower dimension, there are three basic types of transformation: translation, scaling and rotation. We shall represent transformations as square matrices (now they will be 4 × 4). A general point in space rela
