Motion Interpolation (computer Graphics)
Motion interpolation is a programming technique in data-driven character animation that creates transitions between example motions and extrapolates new motions. Example motions are often created through keyframing or motion capture Motion capture (sometimes referred as mo-cap or mocap, for short) is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robo .... However, keyframing is labor-intensive and lacks varieties of motion, and both processes result in motions that are time-consuming to alter. Motion interpolation provides a much faster alternative to creating new motions through the same means. Implementation Formerly, a popular method of simulating a character's movement involved storing a variety of motions and choosing the most appropriate one during run-time. Unfortunately, storage limitations resulted in repetitive or imperfect results. Instead, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Character Animation
Character animation is a specialized area of the animation process, which involves bringing animated s to life. The role of a character animator is analogous to that of a film or stage actor and character animators are often said to be "actors with a pencil" (or a mouse). Character animators breathe life in their characters, creating the illusion of thought, emotion and personality. Character animation is often distinguished from creature animation, which involves bringing photorealism, photorealistic animals and creatures to life. Origins Winsor McCay's ''Gertie the Dinosaur'' (1914) is often considered the first example of true character animation. Later, Otto Messmer imbued Felix the Cat with an instantly recognizable personality during the 1920s. In the 1930s, Walt Disney made character animation a particular focus of his animation studio, best showcased in productions such as ''Three Little Pigs (film), Three Little Pigs'' (1933), ''Snow White and the Seven Dwarfs (1937 film ...

Keyframing
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 hav ...

Motion Capture
Motion capture (sometimes referred as mo-cap or mocap, for short) is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robots. In filmmaking and video game development, it refers to recording actions of human actors, and using that information to animate digital character models in 2-D or 3-D computer animation.Andrew Harris Salomon, Feb. 22, 2013, Backstage MagazineGrowth In Performance Capture Helping Gaming Actors Weather Slump Accessed June 21, 2014, "..But developments in motion-capture technology, as well as new gaming consoles expected from Sony and Microsoft within the year, indicate that this niche continues to be a growth area for actors.

Animation Techniques
Animation is a method by which still figures are manipulated to appear as moving images. In traditional animation, images are drawn or painted by hand on transparent celluloid sheets to be photographed and exhibited on film. Today, most animations are made with computer-generated imagery (CGI). Computer animation can be very detailed 3D animation, while 2D computer animation (which may have the look of traditional animation) can be used for stylistic reasons, low bandwidth, or faster real-time renderings. Other common animation methods apply a stop motion technique to two- and three-dimensional objects like paper cutouts, puppets, or clay figures. A cartoon is an animated film, usually a short film, featuring an exaggerated visual style. The style takes inspiration from comic strips, often featuring anthropomorphic animals, superheroes, or the adventures of human protagonists. Especially with animals that form a natural predator/prey relationship (e.g. cats and mice, coyo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
