Que. | Consider the Breshenham’s line generation algorithm for a line with gradient greater than one, current point (xi, yi) and decision parameter, di. The next point to be plotted (xi+1, yi+1) and updated decision parameter, di+1, for di < 0 are given as ................. (A) xi+1 = xi+1 yi+1 = yi di+1 = di + 2 dy (B) xi+1 = xi yi+1 = yi + 1 di+1 = di + 2 dx (C) xi+1 = xi yi+1 = yi + 1 di+1 = di + 2 (dx – dy) (D) xi+1 = xi + 1 yi+1 = yi + 1 di+1 = di + 2 (dy – dx) |
