Q74.
Consider the midpoint (or Bresenham) algorithm for rasterizing lines given below:

Which statements are true?

P: For a line with slope m>1, we should change the outer line in line (4) to be over y.
Q: Lines (10) and (12) update the decision variable d through an incremental evaluation of the line equation f.
R: The algorithm fails if d is over 0.
1.   Input (x1,y1) and (x2,y2)
2.   y=y1

5.   do
6.        plot(x,y)
7.        if (d<0)
8.        then
9.             y=y+1
10.          d=d+(y1−y2)+(x2−x1)
11.      else
12.          d=d+(y1−y2)
13.      end
14.  end
Discuss
Answer: (c).P and Q only

Q77.
In 3D Graphics, which of the following statements about perspective and parallel projection is/are true?

P: In a perspective projection, the farthest an object is from the centre of projection, the smaller it appears.

Q78.
In 3D Graphics, which of the following statements is/are true?

P: Back-face culling is an example of an image-precision visible-surface determination procedure.
