Animation Ann Ware
Animation A simulation of movement or the perception of motion created by displaying a series of pictures or frames
2D Animation • The creation of moving pictures in a two-dimensional environment, such as those created with computerized animation software. • Objects move along a horizontal axis (x-axis) for simulating forward and backward movement • Objects move along a vertical axis (y-axis) for up and down movement
3D Animation • The creation of moving pictures in a three-dimensional environment; objects can be rotated and moved like real objects. • In addition to moving along the X-Y axis, objects can also move closer or farther away by moving along the z-axis.
2D vs 3D • Objects in 2D animation are flat, like a painting or photograph. • In 3D animations, objects are like sculptures—they have a front, back, top and bottom.
Types of Animation • Frame • Stop Motion • Morphing • Warping
Frame Animation • A computer animation technique that creates movement one frame at a time; the illusion of movement is created by displaying objects in slightly different poses or positions, one frame after another in rapid succession
Stop Motion • Animation where a model is moved incrementally and photographed one frame at a time
Morphing • A special-effects process in which persons or objects seem to change shape, form, etc.
Warping • A special-effects process in which an object is bent or twisted out of shape
Special Effects • Animation is obviously a key component in special effects • The application of computer graphics (specifically 3D animation) to special effects is known as computer generated imagery (CGI)
Key Terms • Frame – An individual picture in a sequence of images • Frames per second (fps) or frame rate: The number of frames per second at which an animation or video is intended to be viewed • Looping – Playing a sequence of frames over and over
Key Terms • Tweening – Short for in-betweening, an animation technique that, based on starting and ending shapes, creates the necessary “in-between” frames • Key frame – A frame in an animated sequence of frames which is drawn or otherwise constructed directly by the user rather than generated by the software
Software • Flash • Ulead Gif Animator • Photoshop • Morpheus • Fantamorph
