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 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). General overview Computer animation can be very detailed 3D animation, while 2D c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animator
An animator is an artist who creates 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 Page layout, 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 i ...

Debug
In engineering, debugging is the process of finding the root cause, workarounds, and possible fixes for bugs. For software, debugging tactics can involve interactive debugging, control flow analysis, 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 term ''bug'', in the sense of defect, dates back at least to 1878 when Thomas Edison wrote "little faults and difficulties" in his inventions as "Bugs". A popular story from the 1940s is from Admiral Grace Hopper. While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay that impeded operation and wrote in a log book "First actual case of a bug being found". Although probably a joke, conflating the two meanings of bug (biological and defect), the story indicates that the term was used in t ...
