Why do Movies Cost so much to Make?
One part might start the motion and the other is pulled along, arriving at its final position (or follow through) a bit later than the first part. Inverse kinematics basically involves reversing the hierarchy and putting the child in charge, so when you want a character to start walking, you move its foot into position and the rest of the leg follows appropriately. If you want to hand draw every frame, all the frames can be key frames. You might also want to set the length of your animation (either in time or in frames). But if you want to see your objects and characters from different angles, you have to draw or create different views of the characters from all the angles you need. You'll likely need to set the frame rate (the number of frames that will play per second) and the dimensions of your animation (often, but not always, in pixels).
In most software packages, you can scrub across the timeline to see your animation in motion, or you can click on individual frames in the timeline to view what's in that frame. Someone still has to design and create characters, backgrounds and other elements and then carefully arrange them over a series of frames to create a moving picture. The applications give you tools to draw or create elements using your input device of choice (mouse, trackpad or pen tablet). Most applications also allow you to lay down audio tracks on your timeline and scrub through them (listen to bits back and forth) to work on timing and sync up your animation to the sound or music. This allows you to create and work with 3-D objects and characters and to move them around in three dimensions (albeit virtual ones). Knowledge of basic physics, especially the Newtonian laws of motion, will help make your characters move and interact in believable ways. Those are just some very basic steps to make something move or change on screen. In those cases, rather than see the object move, you'd either see it shrink or slowly change color. If you let the parent object (say the hip) just drag its children (thigh, calf and foot) along when it moves, the motion will be unnatural.
But as time passes and the graphics magicians come up with better and better algorithms and tools, even the software you can run at home is getting more robust and incorporating more realistic hair, skin, texture and motion effects. With 2-D, the closest comparable technique is importing video, putting it on a layer and tracing over it to capture the motion frame by frame (a technique called rotoscoping). Haan, Jen. "Animation Learning Guide for Flash: Frame rates." Adobe. You build your animation in an empty area in the animation software window sometimes, but not always, referred to as the stage. Both ILM and Pixar, along with other emerging computer graphics houses, would develop lots of technical innovations for use in computer animation, some of which eventually filtered into commercially available software. They are similar in layout to a lot of Windows or Mac apps, but with lots of tools specific to creating graphics and animation. All of these fields come into play in software's ability to create computer graphics and animation, youtube shorts and they've also been used to build a lot of handy quick tools and automation into the various software packages. Some people still create traditional hand-drawn animation, but most of the cartoons we see today are created using computer software.

The first 3-D rendered movie, a short called "A Computer Animated Hand," was created in 1972 by Ed Catmull and Fred Parke at the University of Utah. Thornhill, Ted. "Nearly 40, but still looking good: How Pixar founders made the world's first 3-D computer special effects in 1972." Daily Mail. Ivan Sutherland gained temporary access to an old TX-2 computer. The TX-2 was a giant multitasking mainframe created in the 1950s that was used for military applications, air traffic control, payroll and census processing, and various other tasks. This created longer, more detailed cartoons than people had seen before, but it required creating a large number of images (usually around 24 per second of film). Early devices like the zoetrope (a cylinder with images inside that appeared to be moving when spun) were created to view what amounted to very short cartoons, but the invention of photography, and then projectors, took animation to a whole new level. For instance, the upper part of a leg moves, followed by the calf, then the foot, with hair or clothing lagging behind and catching up after a person moves. When creating a stand-alone animation, 2-D versus 3-D may be a choice of style or of budget; you might not be able to afford the time or hardware and software required to render 3-D movies.
