Which feature records the beginning and end of each transformation in animation?

• A. Frame Rate
• B. Polygons
• C. Main Toolbar
• D. Keyframes

Answer: (D)

Keyframes are the markers that record the values of an object's transformation at specific moments in time. When you set a keyframe, you save the current position, rotation, and scale for that frame. Later, as you scrub the timeline and transform the object again, you place another keyframe at a new frame, capturing the new values. The animation system then interpolates between these keyframes, producing the motion from the start to the end of each transformation. This is distinct from frame rate, which only dictates how many frames are displayed per second; polygons define geometry; and the main toolbar is part of the interface.
