Q. 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.
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.

Q. 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.
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.

Q. A graphic display system has a frame buffer that is 640 pixels wide, 480 pixels high and 1 bit of color depth. If the access time for each pixel on the average is 200 nanoseconds, then the refresh rate of this frame buffer is approximately:

Q. Which of the following statements is/are True regarding the solution to the visibility problem in 3D graphics?

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.
