The Basics of 3D Animation
People without a solid background in programming and art often see 3-D animation as some kind of magic, completely inaccessible to the average person. This may have been true at the beginning of the 3D animation popularity wave, but today, there are a plethora of different tools available to an individual who wants to begin doing 3D animation. If you do not have the right background in computers, do not worry; there are plenty of tools available for people who are interested in learning 3D animation and the various techniques associated with it.
Three Steps to 3D: Modeling, Layout and Animation, and Rendering
Modeling: The Building Blocks of 3D There are really three steps to creating a 3D animation, no matter how long or short the animation is. The first step is the modeling phase. Originally, models were often made from clay or wire. Today, they can be made on the computer by an artist using one of the many different 3D modeling tools. They can also be scanned into the computer, if they are inanimate objects; similarly, the technology exists today that allows animators to scan live beings into the computer using a special suit. This technology is often used in big-budget movies.
Layout and Animation: The Who, Where, and What of Animation After the modeling, the animator has to take care of the layout and animation of a scene. The objects that the animator has modeled need to be placed in the world that the animator is going to manipulate. In this step, the animator defines the special relationships and ratios in the scene. For example, this is the step where an animator will define that the main character of his or her animation will always be bigger than a lamp or an apple. After the layout, the animator will begin the animation. This defines how the models move about in the location, what they do, and so on. Animation can be done with key-framing, inverse kinematics, motion capture, and physical stimulation. It is rare for these techniques to be used independently from each other; it is more common for them to be used together to create a more believable scene.
Rendering: Making an Image The process of rendering an image makes a model into an image. This can happen in a variety of ways, but many beginning animators choose to use one of the many computer programs that will help the animator by doing the rendering for him or her. Rendering can result in realistic images, like the ones in a computer or video game, or non-photorealistic images, like the ones in children?s movies. Essentially, the aesthetic is entirely up to the animator!
