2.02A History of Animation 2.02 Develop Computer Animations
Animation The rapid display of a sequence of images of 2-D or 3-D artwork or model positions in order to create an illusion of movement. Relies on persistence of vision to create the illusion of movement.
Persistence of Vision In the early 1800s, the phenomenon known as persistence of vision gave mankind the first glimpse into the modern world of animation. Persistence of vision refers to the way our eyes retain images for a split second longer than they actually appear, making a series of quick flashes appear as one continuous picture.
Persistence of Vision Using a flipbook, you can see the persistence of vision effect in action. If you have a different sequential drawing on each page of the flipbook and you flip through the pages rapidly, the drawings appear to move.flipbook Examples of Early Animation Examples
Traditional Animation Also called cel animation or hand-drawn animation.cel animation Begins with a storyboard. A preliminary soundtrack is recorded. Penciled drawings are made by lead animators of keyframes. Pencil tests are prepared. Artists called in-betweeners draw the frames between the keyframes. The drawings are traced onto cels and painted. Finally, they are photographed.
Computer Assisted Animation The computer is used to make the animation process quicker and easier. Usually involves 2-D images Can be hand-drawn and scanned into the computer. Can be drawn directly into the computer using graphics tablets. The images are positioned into keyframes containing the most important movements. Tweening is then performed by the computer to create images between keyframes.
Computer Assisted Animation Even though computers are now used extensively, many traditional steps are still used. Storyboarding Pencil Testing Keyframes Tweening
Computer Generated Animation All images, objects and animation are created on the computer. Typically uses 3-D images. Adds two steps to the animation process. Modeling – process of creating a wireframe structure of the 3-D objects and scenes. Rendering – process of applying colors, textures, shadows, transparency, etc. to create the final image or animation.
3-D Graphics and Animation 3-D animations are more complex. Creating 3-D animations involves modeling, animation, and rendering. Modeling is creating broad contours and structure of 3-D objects and scenes. Animation is determining the motions of the objects. Rendering involves determining colors, surface textures, and amounts of transparency of objects.
Computer Generated Animation Motion capture can be used to create animation. Actors wear special suits that allow the computer to capture their movements. The movements can then be applied to computer-generated graphics. Examples: The Polar Express Avatar
Traditional animation is defined as the process of creating the illusion of motion by viewing a series of individual drawings successively. Computer animation is creating a digital scene by digitally recording cells, sorting them on an electronic storyboard, and displaying them electronically in succession.
