Webwhen a line is to be drawn from (0,0) to (6,6) using DDA line drawing algorithm, the initial values for x and y are…….. when a line with end-points (20,10) and (30,18) is to be drawn using DDA line drawing algrithm, ………is chosen as one raster unit. the best line drawing algorithm among all possible line drawing algorithm is…………. WebMar 11, 2024 · Use DDA Algorithm to draw a line from (2,3) to (9,8). S-1: x1=2, y1=3 and x2=9 , y2=8. S-2: Calculate Slope m = (8-3)/ (9-2) = 5/7, which is less than 1. S-3: Since m is less than one that means we would increase x and calculate y. S-4: So new x would be equal to old x plus 1 and calculate y as new y = old y +m (slope).
