Which of the following is basically a marker used to specify an object's position and attributes at a given point in time?
Show Hint
Without Keyframes, a 3D animation engine cannot calculate motion curves. Setting a keyframe is like planting a physical anchor point on a graph of values over time.

- Keyframe
- Frame rate

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Foundations of Computer Interpolation:
In digital animation, software does not require the animator to draw every single frame of a sequence. Instead, the animator establishes milestone frames, and the computer interpolates (calculates the in-between values) the transition.
Step 2: Defining the Keyframe:
A Keyframe is a marker on the timeline that locks in the specific values of an object's properties (such as Translation, Rotation, Scale, Opacity, or Color) at a specific point in time ($t$). Once two keyframes are established, the software automatically generates smooth motion between those points.
Step 3: Evaluating Options:
Frame timeline (A) is the visual grid. Framework (B) is a structure. Frame rate (D) is the playback speed (FPS). Thus, Keyframe (Option C) is the correct term.
