Detailed explanation-1: -Option: C, Explanation-We translate a two-dimensional point by adding translation distance.
Detailed explanation-2: -We translate a two-dimensional point by adding translation distances, tx and ty, to the original coordinate position (x, y) to move the point to a new position (x’, y’) (Fig. 5-1). x’ = x + tx, y’ = y + ty (5.1) Page 2 The translation distance pair (tx, ty) is called a translation vector or shift vector.
Detailed explanation-3: -Answer-A, Explanation-The two-dimensional translation equation in the matrix form is P’=P+T.
Detailed explanation-4: -Answer: (c) x’ = x + tx and y’ = y + ty Explanation: We translate a 2-D point by adding translation distance, tx, and ty, to the original coordinates position (x, y) to move the points to a new position (x’, y’).
Detailed explanation-5: -2D Translation is a process of moving an object from one position to another in a two dimensional plane. Page 2. Consider a point object O has to be moved from one position to another in a 2D plane. Let-• Initial coordinates of the object O = (Xold, Yold)
