1. What is the primary purpose of keyframe interpolation in
computer-aided animation?
A. Compressing animation files
B. Generating intermediate frames between keyframes
C. Simplifying character rigging processes
D. Increasing the polygon count of models
- ANS: B. Generating intermediate frames between
keyframes
- Rationale: Interpolation helps create smooth transitions by
automatically generating intermediate frames.

,2. Which algorithm is commonly used for motion path
smoothing in computer-aided animation?
A. Binary Search
B. Catmull-Rom Spline
C. Kruskal's Algorithm
D. Floyd-Warshall Algorithm
- ANS: B. Catmull-Rom Spline
- Rationale: Catmull-Rom splines are used in animation to
produce smooth motion paths.

enhances realism by simulating the scattering of light within
translucent objects?
A. Ambient Occlusion
B. Subsurface Scattering
C. Ray Marching
D. Specular Mapping
- ANS: B. Subsurface Scattering

,4. What is the main benefit of using motion capture (mocap)
data in computer-aided animation?
A. Reduces the need for texture mapping
B. Enables real-time physics simulation
C. Captures realistic human motion with high fidelity
D. Minimizes computational rendering time
- ANS: C. Captures realistic human motion with high fidelity
- Rationale: Mocap records real-world motion to be applied
directly to animated characters.
5. Which tool in animation software is primarily used for
refining lip-syncing in animated characters?
A. Graph Editor
B. Blend Shape Tool
C. IK Solver
D. Texture Mapping Tool
- ANS: B. Blend Shape Tool
- Rationale: Blend shapes are used to modify facial
expressions, including accurate lip-syncing.

6. __________ is the technique used in computer-aided
animation to create a realistic sense of depth by simulating how
objects become less detailed and lighter in color as they recede
into the distance.
- ANS: Atmospheric Perspective
- Rationale: Atmospheric perspective enhances depth
perception by simulating atmospheric effects.
7. In animation, the __________ system controls a character's
movement by mapping motion data to a hierarchical structure of
bones or joints.
- ANS: Skeletal Animation
- Rationale: Skeletal animation is widely used for character
motion in computer-aided animation.
8. The __________ effect is used to simulate motion blur in
animated sequences.
- ANS: Temporal Aliasing
- Rationale: Motion blur reduces the strobing effect and adds
realism to fast-moving objects.
