Secondary Motion
Secondary animation also known as secondary motion, is flat motions generated as a reaction to the movement of primary motion by a character. It is significant in animation because it amplifies the character's motion via effects that appear to be driven by the motion, i.e. it makes the character's motion seem natural. Examples of secondary motion include the rippling of water, swish of a cloak, or jiggle of body parts when a person is moving. These passive effects have many degrees of freedom, and complex interactions with characters, thus making them hard to animate by hand (hand animation), or via computer software. Techniques Creating a second motion requires using a technique called coupling that combines simulations of individual objects allowing them to interact together to produce secondary motion. The coupling can be divided into three categories: two-way coupled, one-way coupled, and hybrid. # Two-way coupled - The purpose of a two-way coupled simulation is to model the ...

Animation
Animation is a method by which image, still figures are manipulated to appear as Motion picture, moving images. In traditional animation, images are drawn or painted by hand on transparent cel, 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 Computer animation#Animation methods, 3D animation, while Traditional animation#Computers and traditional animation, 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 cutout animation, paper cutouts, puppets, or Clay animation, clay figures. A cartoon is an animated film, usually a short film, featuring an cartoon, exaggerated visual style. The style takes inspiration from comic strips, often featuring anthropomorphi ...

Real-time Computer Graphics
Real-time computer graphics or real-time rendering is the sub-field of computer graphics focused on producing and analyzing images in real time. The term can refer to anything from rendering an application's graphical user interface (GUI) to real-time image analysis, but is most often used in reference to interactive 3D computer graphics, typically using a graphics processing unit (GPU). One example of this concept is a video game that rapidly renders changing 3D environments to produce an illusion of motion. Computers have been capable of generating 2D images such as simple lines, images and polygons in real time since their invention. However, quickly rendering detailed 3D objects is a daunting task for traditional Von Neumann architecture-based systems. An early workaround to this problem was the use of sprites, 2D images that could imitate 3D graphics. Different techniques for rendering now exist, such as ray-tracing and rasterization. Using these techniques and advan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animator
An animator is an artist who creates multiple images, known as frames, which give an illusion of movement called animation when displayed in rapid sequence. Animators can work in a variety of fields including film, television, and video games. Animation is closely related to filmmaking and like filmmaking is extremely labor-intensive, which means that most significant works require the collaboration of several animators. The methods of creating the images or frames for an animation piece depend on the animators' artistic styles and their field. Other artists who contribute to animated cartoons, but who are not animators, include layout artists (who design the backgrounds, lighting, and camera angles), storyboard artists (who draw panels of the action from the script), and background artists (who paint the "scenery"). Animated films share some film crew positions with regular live action films, such as director, producer, sound engineer, and editor, but differ radically ...

Debug
In computer programming and software development, debugging is the process of finding and resolving '' bugs'' (defects or problems that prevent correct operation) within computer programs, software, or systems. Debugging tactics can involve interactive debugging, control flow analysis, unit testing, integration testing, log file analysis, monitoring at the application or system level, memory dumps, and profiling. Many programming languages and software development tools also offer programs to aid in debugging, known as ''debuggers''. Etymology The terms "bug" and "debugging" are popularly attributed to Admiral Grace Hopper in the 1940s. While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay and thereby impeding operation, whereupon she remarked that they were "debugging" the system. However, the term "bug", in the sense of "technical error", dates back at least to 1878 and Thomas Edison who describes the "little ...
