Walk Cycle
In animation, a walk cycle is a series of frames or illustrations drawn in sequence that loop to create an animation of a walking character. The walk cycle is looped over and over, thus avoiding having to animate each step again. Creating a walk cycle Walk cycles can be broken up into four key frames: the ''forward contact point'', the first ''passing pose'', the ''back contact point'', and the second ''passing pose''. Frames that are drawn between these key poses (traditionally known as in-betweens) are either hand-drawn or interpolated using computer software. Besides the apparent move of the legs, many more details are necessary for a convincing walk cycle, like animation timing, movement of the arms, head and torsion of the whole body.Walkcycle tutorial from http://www.idleworm.com There exist many techniqu ...

Animation
Animation is a filmmaking technique whereby still images are manipulated to create moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Animation has been recognised as an artistic medium, specifically within the entertainment industry. Many animations are either traditional animations or computer animations made with computer-generated imagery (CGI). Stop motion animation, in particular claymation, has continued to exist alongside these other forms. Animation is contrasted with live action, although the two do not exist in isolation. Many moviemakers have produced films that are a hybrid of the two. As CGI increasingly approximates photographic imagery, filmmakers can easily composite 3D animations into their film rather than using practical effects for showy visual effects (VFX).

Film Frame
In filmmaking, video production, animation, and related fields, a frame is one of the many '' still images'' which compose the complete ''moving picture''. The term is derived from the historical development of film stock, in which the sequentially recorded single images look like a framed picture when examined individually. The term may also be used more generally as a noun or verb to refer to the edges of the image as seen in a camera viewfinder or projected on a screen. Thus, the camera operator can be said to keep a car in frame by panning with it as it speeds past. Overview When the moving picture is displayed, each frame is flashed on a screen for a short time (nowadays typically , , or of a second) and then immediately replaced by the next one. Persistence of vision blends the frames together, producing the illusion of a moving image. The frame is also sometimes used as a unit of time, so that a momentary event might be said to last six frames, the actual duration of w ...

Walking
Walking (also known as ambulation) is one of the main gaits of terrestrial locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined as an " inverted pendulum" gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the usable number of limbs—even arthropods, with six, eight, or more limbs, walk. In humans, walking has health benefits including improved mental health and reduced risk of cardiovascular disease and death. Difference from running The word ''walk'' is descended from the Old English ''wealcan'' 'to roll'. In humans and other bipeds, walking is generally distinguished from running in that only one foot at a time leaves contact with the ground and there is a period of double-support. In contrast, running begins when both feet are off the ground with each step. This distinction has the status of a formal requirement in competitive walking events. For quadrupedal ...

Key Frame
In animation and filmmaking, a key frame (or keyframe) is a drawing or shot that defines the starting and ending points of a smooth transition. These are called ''frames'' because their position in time is measured in frames on a strip of film or on a digital video editing timeline. A sequence of key frames defines which movement the viewer will see, whereas the position of the key frames on the film, video, or animation defines the timing of the movement. Because only two or three key frames over the span of a second do not create the illusion of movement, the remaining frames are filled with " inbetweens". Use of key frames as a means to change parameters In software packages that support animation, especially 3D graphics, there are many parameters that can be changed for any one object. One example of such an object is a light. In 3D graphics, lights function similarly to real-world lights. They cause illumination, cast shadows, and create specular highlights. Lights ha ...

Inbetweening
Inbetweening, also known as tweening, is a process in animation that involves creating intermediate frames, called inbetweens, between two keyframes. The intended result is to create the illusion of movement by smoothly transitioning one image into another. Traditional animation Traditional inbetweening involves the use of a light table to draw a set of pencil and paper drawings. The process of inbetweening in traditional animation starts with a primary artist, who draws key frames to define movement. After the testing and approval of a rough animation, the scene is passed down to assistants, who perform clean-up and add necessary inbetweening. In large studios, assistants usually add breakdowns, which define the movement in more detail. The scene is then passed down to another assistant, the inbetweener, who completes the animation. In small animation teams, animators will often carry out the full inbetweening process themselves. Dick Huemer developed this system in the 1920s ...

2D Computer Graphics
2D computer graphics is the computer-based generation of digital images—mostly from two-dimensional models (such as 2D geometric models, text, and digital images) and by techniques specific to them. It may refer to the branch of computer science that comprises such techniques or to the models themselves. 2D computer graphics are mainly used in applications that were originally developed upon traditional printing and drawing technologies, such as typography, cartography, technical drawing, advertising, etc. In those applications, the two-dimensional image is not just a representation of a real-world object, but an independent artifact with added semantic value; two-dimensional models are therefore preferred, because they give more direct control of the image than 3D computer graphics (whose approach is more akin to photography than to typography). In many domains, such as desktop publishing, engineering, and business, a description of a document based on 2D computer graph ...

3D Computer Graphics
3D computer graphics, sometimes called Computer-generated imagery, CGI, 3D-CGI or three-dimensional Computer-generated imagery, computer graphics, are graphics that use a three-dimensional representation of geometric data (often Cartesian coordinate system#Cartesian coordinates in three dimensions, Cartesian) that is stored in the computer for the purposes of performing calculations and rendering digital images, usually 2D images but sometimes 3D images. The resulting images may be stored for viewing later (possibly as an Computer animation, animation) or displayed in Real-time computer graphics, real time. 3D computer graphics, contrary to what the name suggests, are most often displayed on two-dimensional displays. Unlike 3D film and similar techniques, the result is two-dimensional, without visual depth perception, depth. More often, 3D graphics are being displayed on 3D displays, like in virtual reality systems. 3D graphics stand in contrast to 2D computer graphics which t ...

Stop Motion
Stop-motion (also known as stop frame animation) is an animated filmmaking and special effects technique in which objects are physically manipulated in small increments between individually photographed frames so that they will appear to exhibit independent motion or change when the series of frames is played back. Any kind of object can thus be animated, but puppets with movable joints (puppet animation) or clay figures (claymation) are most commonly used. Puppets, models or clay figures built around an armature are used in model animation. Stop motion with live actors is often referred to as pixilation. Stop motion of flat materials such as paper, fabrics or photographs is usually called cutout animation. Terminology The term "stop-motion", relating to the animation technique, is often spelled without a hyphen as "stop motion"—either standalone or as a compound modifier. Both orthographic variants, with and without the hyphen, are correct, but the hyphenated one is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cut-out Animation
Cutout animation is a form of stop-motion animation using flat characters, props and backgrounds cut from materials such as paper, card, stiff fabric or photographs. The props would be cut out and used as puppets for stop motion. The world's earliest known animated feature films were cutout animations (made in Argentina by Quirino Cristiani), as is the world's earliest surviving animated feature '' Die Abenteuer des Prinzen Achmed'' (1926) by Lotte Reiniger. The technique of most cutout animation is comparable to that of shadow play, but with stop motion replacing the manual or mechanical manipulation of flat puppets. Some films, including ''Die Abenteuer des Prinzen Achmed'', also have much of their silhouette style in common with shadow plays. Cutout animation pioneer Lotte Reiniger studied the traditions of shadow play and created several shadow play film sequences, including a tribute to François Dominique Séraphin in Jean Renoir's film ''La Marseillaise'' (1938).

Rotoscoping
Rotoscoping is an animation technique that animators use to trace over motion picture footage, frame by frame, to produce realistic action. Originally, live-action film images were projected onto a glass panel and traced onto paper. This projection equipment is referred to as a rotoscope, developed by Polish-American animator Max Fleischer. This device was eventually replaced by computers, but the process is still called rotoscoping. In the visual effects industry, ''rotoscoping'' refers to the technique of manually creating a matte for an element on a live-action plate so it may be composited over another background. Technique Rotoscoping has often been used as a tool for visual effects in live-action films. By tracing an object, the filmmaker creates a silhouette (called a matte) that can be used to extract that object from a scene for use on a different background. Rotoscoping in the digital domain is often aided by motion-tracking and onion-skinning software. R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
