From Wikipedia.org: "Visualization or visualisation (see spelling differences) is any technique for creating images, diagrams, or animations to communicate a message. Visualization through visual imagery has been an effective way to communicate both abstract and concrete ideas since the dawn of man. Examples from history include cave paintings, Egyptian hieroglyphs, Greek geometry, and Leonardo da Vinci's revolutionary methods of technical drawing for engineering and scientific purposes."
Animation is a process by which several still images are shown in sequence, producing the illusion of movement. You will learn that characters and scenes can be animated by hand-drawing several frames in a sequence so they can be played back. Animation can also be produced on a computer through the use of a technology called "keyframing." Either technique can be used to generate film, television, video game and virtual reality scenes.
In Betweens When a 3D animation tool like Blender or Adobe Animate is used to produce the animation of a character running, the process is very much like posing action figures. The first "frame" in the sequence is set up as the starting point and designated the first keyframe. This is a marked point in the sequence the animation tool can return to when it is necessary to start over.
The last frame in the sequence is also a keyframe, representing the point at the end of the timeline where the animation will stop. In your education, you'll learn what the animation tool does. But for now, all you need to know is that it mathematically calculates all the frames from the first keyframe to the last keyframe, determining how the character's pose must be changed so by the time it reaches the end, it will be posed to match the ending keyframe's position. This is a process called "in-betweening" or "tweening" for short. Learn more here.
Visualizing Animation The easiest way to imagine this process is to consider an animation that plays back at 24 frames a second. In the first frame, you place a ball by a red flag. Two yards away, there is a green flag. So you advance the animation to frame number 72 and set a keyframe there. Then you move the ball so it is next to the green flag.
Your animation tool will calculate where the ball should be in frame two, frame three, and so forth until it arrives at the keyframe at frame 72. When you play the animation back, the ball will move two yards from the red flag to the green flag in three seconds, at which point the animation will stop.
Keyframing can be used to do all kinds of complex animation tasks from machinery demonstrations to lightning strikes to a drag race. If you want to animate, there are many tools and instructional programs available to help you learn the basics. After that, the more you practice, the better you'll get!
