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
3. d=f(x1+1,y1+1/2) //f is the implicit form of a line
4. for x=x1 to x2
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
P: In a perspective projection, the farthest an object is from the centre of projection, the smaller it appears.
Q: Parallel projection is equivalent to a perspective projection where the viewer is standing infinitely far away.
R: Perspective projections do not preserve straight lines.
P: Back-face culling is an example of an image-precision visible-surface determination procedure.
Q: Z- buffer is a 16-bit, 32-bit, or 64 bit field associated with each pixel in a frame buffer that can be used to determine the visible
surfaces at each pixel.
S1: The Painter’s algorithm sorts polygons by depth and then paints (scan - converts) each Polygon on to the screen starting with the most nearest polygon.
S2: Backface Culling refers to eliminating geometry with backfacing normals.
