  • Animation: Types
    Animation: Animation is a dynamic medium in which images or objects 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 (CGI). Commonly the effect of animation is achieved by a rapid succession of sequential images that minimally differ from each other. Apart from short films, feature films, animated gifs and other media dedicated to the display moving images, animation is also heavily used for video games, motion graphics and special effects. The history of animation started long before the development of cinematography. Humans have probably attempted to depict motion as far back as the Paleolithic period. Shadow play and the magic lantern offered popular shows with moving images as the result of manipulation by hand and/or some minor mechanics Computer animation has become popular since toy story (1995), the first feature-length animated film completely made using this technique. Types: Traditional animation (also called cel animation or hand-drawn animation) was the process used for most animated films of the 20th century. The individual frames of a traditionally animated film are photographs of drawings, first drawn on paper. To create the illusion of movement, each drawing differs slightly from the one before it. The animators' drawings are traced or photocopied onto transparent acetate sheets called cels which are filled in with paints in assigned colors or tones on the side opposite the line drawings. The completed character cels are photographed one-by-one against a painted background by rostrum camera onto motion picture film.

  • The Uses of Animation 1
    The Uses of Animation 1 1 The Uses of Animation ANIMATION Animation is the process of making the illusion of motion and change by means of the rapid display of a sequence of static images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon. Animators are artists who specialize in the creation of animation. Animation can be recorded with either analogue media, a flip book, motion picture film, video tape,digital media, including formats with animated GIF, Flash animation and digital video. To display animation, a digital camera, computer, or projector are used along with new technologies that are produced. Animation creation methods include the traditional animation creation method and those involving stop motion animation of two and three-dimensional objects, paper cutouts, puppets and clay figures. Images are displayed in a rapid succession, usually 24, 25, 30, or 60 frames per second. THE MOST COMMON USES OF ANIMATION Cartoons The most common use of animation, and perhaps the origin of it, is cartoons. Cartoons appear all the time on television and the cinema and can be used for entertainment, advertising, 2 Aspects of Animation: Steps to Learn Animated Cartoons presentations and many more applications that are only limited by the imagination of the designer. The most important factor about making cartoons on a computer is reusability and flexibility. The system that will actually do the animation needs to be such that all the actions that are going to be performed can be repeated easily, without much fuss from the side of the animator.

  • The Formation of Temporary Communities in Anime Fandom: a Story of Bottom-Up Globalization ______
    THE FORMATION OF TEMPORARY COMMUNITIES IN ANIME FANDOM: A STORY OF BOTTOM-UP GLOBALIZATION ____________________________________ A Thesis Presented to the Faculty of California State University, Fullerton ____________________________________ In Partial Fulfillment of the Requirements for the Degree Master of Arts in Geography ____________________________________ By Cynthia R. Davis Thesis Committee Approval: Mark Drayse, Department of Geography & the Environment, Chair Jonathan Taylor, Department of Geography & the Environment Zia Salim, Department of Geography & the Environment Summer, 2017 ABSTRACT Japanese animation, commonly referred to as anime, has earned a strong foothold in the American entertainment industry over the last few decades. Anime is known by many to be a more mature option for animation fans since Western animation has typically been sanitized to be “kid-friendly.” This thesis explores how this came to be, by exploring the following questions: (1) What were the differences in the development and perception of the animation industries in Japan and the United States? (2) Why/how did people in the United States take such interest in anime? (3) What is the role of anime conventions within the anime fandom community, both historically and in the present? These questions were answered with a mix of historical research, mapping, and interviews that were conducted in 2015 at Anime Expo, North America’s largest anime convention. This thesis concludes that anime would not have succeeded as it has in the United States without the heavy involvement of domestic animation fans. Fans created networks, clubs, and conventions that allowed for the exchange of information on anime, before Japanese companies started to officially release anime titles for distribution in the United States.

  • Animation 1 Animation
    Animation 1 Animation The bouncing ball animation (below) consists of these six frames. This animation moves at 10 frames per second. Animation is the rapid display of a sequence of static images and/or objects to create an illusion of movement. The most common method of presenting animation is as a motion picture or video program, although there are other methods. This type of presentation is usually accomplished with a camera and a projector or a computer viewing screen which can rapidly cycle through images in a sequence. Animation can be made with either hand rendered art, computer generated imagery, or three-dimensional objects, e.g., puppets or clay figures, or a combination of techniques. The position of each object in any particular image relates to the position of that object in the previous and following images so that the objects each appear to fluidly move independently of one another. The viewing device displays these images in rapid succession, usually 24, 25, or 30 frames per second. Etymology From Latin animātiō, "the act of bringing to life"; from animō ("to animate" or "give life to") and -ātiō ("the act of").[citation needed] History Early examples of attempts to capture the phenomenon of motion drawing can be found in paleolithic cave paintings, where animals are depicted with multiple legs in superimposed positions, clearly attempting Five images sequence from a vase found in Iran to convey the perception of motion. A 5,000 year old earthen bowl found in Iran in Shahr-i Sokhta has five images of a goat painted along the sides.

  • Animating Race the Production and Ascription of Asian-Ness in the Animation of Avatar: the Last Airbender and the Legend of Korra
    Animating Race The Production and Ascription of Asian-ness in the Animation of Avatar: The Last Airbender and The Legend of Korra Francis M. Agnoli Submitted for the degree of Doctor of Philosophy (PhD) University of East Anglia School of Art, Media and American Studies April 2020 This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with the author and that use of any information derived there from must be in accordance with current UK Copyright Law. In addition, any quotation or extract must include full attribution. 2 Abstract How and by what means is race ascribed to an animated body? My thesis addresses this question by reconstructing the production narratives around the Nickelodeon television series Avatar: The Last Airbender (2005-08) and its sequel The Legend of Korra (2012-14). Through original and preexisting interviews, I determine how the ascription of race occurs at every stage of production. To do so, I triangulate theories related to race as a social construct, using a definition composed by sociologists Matthew Desmond and Mustafa Emirbayer; re-presentations of the body in animation, drawing upon art historian Nicholas Mirzoeff’s concept of the bodyscape; and the cinematic voice as described by film scholars Rick Altman, Mary Ann Doane, Michel Chion, and Gianluca Sergi. Even production processes not directly related to character design, animation, or performance contribute to the ascription of race. Therefore, this thesis also references writings on culture, such as those on cultural appropriation, cultural flow/traffic, and transculturation; fantasy, an impulse to break away from mimesis; and realist animation conventions, which relates to Paul Wells’ concept of hyper-realism.

  • Delaware Recommended Curriculum Unit Template
    Delaware Recommended Curriculum Unit Template Preface: This unit has been created as a model for teachers in their designing or redesigning of course curricula. It is by no means intended to be inclusive; rather it is meant to be a springboard for a teacher’s thoughts and creativity. The information we have included represents one possibility for developing a unit based on the Delaware content standards and the Understanding by Design framework and philosophy. Subject/Topic Area: Visual Art Grade Level(s): 4 Searchable Key Words: cartoon, animation, cel, storyboard Designed By: Dave Kelleher District: Red Clay Time Frame: Eight 45 minute classes Date: November 18, 2008 Revised: May 2009 Brief Summary of Unit Creating, performing, responding and making connections are learning concepts that are at the core of the Visual and Performing Arts curriculum. This unit will stress the responding concept and the product for responding will be animation. Students will view animated cartoons (non-computer generated) and analyze how multiple uses of “one image”, or cel (short for celluloid- thin sheets of clear plastic that characters are drawn on and then painted), create a story in motion and convey the point/opinion of the animator. Ultimately, focus will center on one individual cel and how it relates to the given point/opinion and, due to its cartoon nature, may/may not effectively convey the opinion (i.e. some people might find it difficult to relate to a serious topic when the character presented is an adorable pink bunny with a bowtie). Because the art world had previously considered animation beneath it, artistic skill and creativity in the creation of characters, emotions, storyline, and backgrounds were often ignored.

India is one of the most preferred outsourcing countries. We not only do outsourcing services, we are also a creator of original animation. Some of the popular original contents are Chota bheem, Little Krishna, Delhi Safari, Arjun, Road side Romeo etc. Animation is a combination of entertainment and technology. It is composed of design, drawing, layout and production of graphically rich multimedia clips. Time and space are important in animation. Those who excel in drawing and creativity can choose animation as their career. An animator’s job is to analyze the script thoroughly and get into the skin of the character. Creating idea, storyboard, Character design, backgrounds, etc and using technical methodology to create stunning visuals short movies is the ideal steps in making a successful animation feature.

  • The Animation Industry: Technological Changes, Production Challenges, and Global Shifts
    THE ANIMATION INDUSTRY: TECHNOLOGICAL CHANGES, PRODUCTION CHALLENGES, AND GLOBAL SHIFTS DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Hyejin Yoon, M.A. ***** The Ohio State University 2008 Dissertation Committee: Approved by Professor Edward J. Malecki, Adviser Professor Nancy Ettlinger Adviser Graduate Program in Geography Professor Darla K. Munroe ABSTRACT Animated films have grown in popularity as expanding markets (such as TV and video) and new technologies (notably computer graphics imagery) have broadened both the production and consumption of cartoons. As a consequence, more animated films are produced and watched in more places, as new “worlds of production” have emerged. The animation production system, specialized and distinct from film production, relies on different technologies and labor skills. Therefore, its globalization has taken place differently from live-action film production, although both are structured to a large degree by the global production networks (GPNs) of the media conglomerates. This research examines the structure and evolution of the animation industry at the global scale. In order to investigate these, 4,242 animation studios from the Animation Industry Database are used. The spatial patterns of animation production can be summarized as, 1) dispersion of the animation industry, 2) concentration in world cities, such as Los Angeles and New York, 3) emergence of specialized animation cities, such as Annecy and Angoulême in France, and 4) significant concentrations of animation studios in some Asian countries, such as India, South Korea and the Philippines. In order to understand global production networks (GPNs), networks of studios in 20 cities are analyzed.
