Question
Define Animation.
Answer
Animation is the technique of creating the illusion of motion by displaying a sequence of images (frames) in rapid succession.
Animation is the process of creating the visual illusion of motion by rapidly displaying a sequence of static images (frames), each slightly different from the previous one. The human visual system's persistence of vision and the phi phenomenon cause the sequential images to be perceived as continuous motion.
Computer animation techniques include keyframe animation (specify key poses, interpolate between them), procedural animation (define motion through algorithms), physics-based simulation (rigid body dynamics, cloth, fluid), and motion capture (recording real-world motion). Standard animation rates are 24 fps (film), 30 fps (NTSC video), and 60+ fps (real-time games).
