Question

Implement the dda algorithm to draw a line from (0 0) to (6 6)

Answer 1

Answer & Explanation:

Let us first calculate the slope of the given line

m = (6-0)/(6-0) = 1

Since the slope of the line is 1, we will sample the points at unit x intervals i.e. dx=1

then the next point on y axis corresponding to the previous point plotted will be

y(k+1) = y(k) + m

The table below shows the points to be plotted

(x,y)

(0,0)

(1,1)

(2,2)

(3,3)

(4,4)

(5,5)

(6,6)
