Why do Movies Cost so much to Make?
Cartoons are fun and entertaining to behold, but they're also a lot of work to create. Animation software that can render 3-D is a necessity when creating graphics to composite into live-action movies, however, and is becoming more and more common for animation of cartoons. They also have to take scene composition into account (including contrast, lighting, perspective and what objects are visible) to build the right mood, convey the intended story and make sure that the audience can tell what's going on. Many also include something called inverse kinematics, which allows for very complex motions, like walking, that are hard or impossible to get right with typical hierarchical motion (called forward kinematics). The study of how body parts or other grouped objects and their joints move to get from one place to another is called kinematics, and it's a term you'll hear often in relation to animation and animation software. You can pick the one that best suits your needs and get to work. And when things don't move as you like, you can go in and tweak the effect of one area or another with changes in number settings or sometimes even strokes of an erasure-type tool.

Not that most of us are going to whip out a Pixar film alone, even if we have years to put into it. Thornhill, Ted.

One part might start the motion and the other is pulled along, video shorts arriving at its final position (or follow through) a bit later than the first part. Another handy tool called onion skinning or ghosting allows you to see your objects in the current frame along with the objects at their positions in one or more previous frames to help you visualize how they are going to move from frame to frame. The editor will show visible curves that represent various attributes of your objects on various axes (for instance, in 3-D animation software, you might have three separate curves for rotation and three for translation, one each for the x, y and z axes). They can just be used to control your character's movement and deformation on two axes rather than three. This allows you to create and work with 3-D objects and characters and to move them around in three dimensions (albeit virtual ones).
This allows you to build rather complex objects (like vehicles) and characters (robot or animal) and to make them move in realistic ways. Something lower, like 12 or 15 frames per second, can be used to decrease the number of frames you or the software will need to fill. Anything involving math (including algebra, geometry, trigonometry, calculus and physics) can be represented by algorithms, which can be programmed into software. There are even some software packages that let you work with both 2-D and 3-D elements together, or zoom around in a three-dimensional environment containing 2-D objects. You can go even lower, but the lower you go, the more jumpy the animation will look. You may even want to do something called "animating on twos," where you keep a 24 fps setting but only animate every other frame. If you want to see a character from different angles, you don't draw multiple versions. 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. If you want to hand draw every frame, all the frames can be key frames. You can also set the camera perspective anywhere and look at your scenes from any vantage point.
You usually have to set camera and light source information before rendering. With enough processing power, skilled animators can now create and display fantastic things that wouldn't have been possible in the past, with an increasing level of realism (if realism is the aim). Some animation applications are easy to jump into after reading or watching a brief tutorial, and others have a steeper learning curve. Some software lets you select and apply preset curves that change the animation in some predictable way, like adding slow-in or slow-out motion, constant change (with linear curves) or sudden stops and starts (with step curves). A lot of software packages also contain lots of motion control settings, including built-in motion effects like squash and stretch controls and preset motion paths that you can put objects on rather than having to create them manually. You can use a selector tool to drag already-created objects to the screen rather than redrawing them. You generally insert key frames anytime there's a change, such as an object appearing or a motion beginning or ending, but you can insert as many key frames as you want. Viewing them in quick succession creates the illusion of motion.
