3. 2.0
4. 1.0

Correct answer: -1.0

Q2. 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.

1. Similar
2. None of the given

2. Two
3. Three
4. One

Correct answer: One

Q4. End points and an intermediate point on the curve, then we now --------------------- quantities that we can express in terms of these coefficients (3 points x 3 coordinates each), and we can use these three points to define a unique curve.

1. Three
2. Nine
3. Six

Correct answer: Nine

Q5. Silhouette edges occur when dot product of surface normal vector and the view vector is __________.

1. Zero
2. One
3. None of the given
4. Both zero and one

Correct answer: Zero

Q6. 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.

1. Same
2. None of the given
3. Different
4. Isolate

Correct answer: Same

1. Endpoints
2. Union
3. Intersection
4. Edges

Correct answer: Intersection

1. Non of the these
2. non parametric curve
3. polygon vector
4. parametric curve

Correct answer: parametric curve

Q10. If the current matrix (according to glMatrixMode) is multiplied by the translation matrix, with the product replacing the current matrix. That is, if M is the current matrix and T is the translation matrix, then M is replaced with -----------------.
