CS602 - Computer Graphics (Semester Quiz # 04 – (Graded))

1. Bit mask to select a window with multisampling support. If multisampling is not available, a --------- -------- window will automatically be chosen. Di-multisampling

Non-multisampling · Mono-multisampling · Multisampling

2. The mathematics of parametric equation is the basis for ------------- curves.

Bresenham · Hermite · Hercules · Tangent

3. If we assign a different value to the parametric variable for the intermediate point, then we obtain different values for the coefficients. This, in turn, means that a different curve is produced, although it passes through the -------------- three points.

Isolate · Different · Same

4. Another way to define a space curve by using intermediate points and the tangents at each end for making the curve

Yes

No

c. d.

5. glutReshapeWindow requests a change in the size of the current window. The width and height parameters are size extents in pixels. The width and height must be ---------------- values. Negative

Non of the given · Neutral · Positive

6. Imagine a curve in three-dimensional space, each point on the curve has a unique set of coordinates: a specific x value, y value, and z value. Each coordinate is controlled by a ------------ -- parametric equation.

Similar · Opposite · Separate

7. While building polygonal model of surfaces, we should use T-intersections.

Yes

No

c. d.

8. To convert the information in the A matrix into that required for the P matrix, we do some simple matrix algebra. First we have

GP = ------------------------------ · UP · NU · NP · UNP
