ITPEC FE Subject A April 2024 Question 17
In the process of creating animation, which of the following is used to record the natural movement of objects, humans, and animals by using sensors and video cameras?
Explanation
Motion capture — sensors and video cameras record real movement, which is then applied to a digital model.
Markers or sensors are attached to a person, animal or object, cameras track them, and the recorded positions drive a 3D character, so the animation keeps the natural motion of the original.
Answer (c)
Why not others:
- •(a) Key frame method — the animator draws or poses key frames by hand and the computer interpolates the frames in between; nothing is recorded
- •(b) Morphing — a gradual transformation of one image or shape into another
- •(d) Pixel shader — a GPU program that calculates the colour of each pixel during rendering, unrelated to capturing motion
Key rule: Key frames are created by the animator, motion capture is recorded from real movement, and morphing interpolates between two shapes.
