A real homography is involutory (of period 2) if and only if a + d = 0. If it is periodic with period n > 2, then it is elliptic, and no loss of generality occurs by assuming that ad − bc = 1. Since the characteristic roots are exp (± hπi / m ), where (h, m) = 1, the trace is a + d = 2 cos (hπ/m). [16] See also [ … Meer weergeven In projective geometry, a homography is an isomorphism of projective spaces, induced by an isomorphism of the vector spaces from which the projective spaces derive. It is a bijection that maps lines to lines, and thus a Meer weergeven The projective line over a field K may be identified with the union of K and a point, called the "point at infinity" and denoted by ∞ (see Meer weergeven In above sections, homographies have been defined through linear algebra. In synthetic geometry, they are traditionally defined as the composition of one or several special homographies called central collineations. It is a part of the fundamental … Meer weergeven Historically, the concept of homography had been introduced to understand, explain and study visual perspective, and, specifically, the difference in appearance of two plane … Meer weergeven A projective space P(V) of dimension n over a field K may be defined as the set of the lines through the origin in a K-vector space V of dimension n + 1. If a basis of V has been fixed, a point of V may be represented by a point Given two … Meer weergeven A projective frame or projective basis of a projective space of dimension n is an ordered set of n + 2 points such that no hyperplane … Meer weergeven There are collineations besides the homographies.
