  • 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.

  • Photo Journalism, Film and Animation
    Syllabus – Photo Journalism, Films and Animation Photo Journalism: Photojournalism is a particular form of journalism (the collecting, editing, and presenting of news material for publication or broadcast) that employs images in order to tell a news story. It is now usually understood to refer only to still images, but in some cases the term also refers to video used in broadcast journalism. Photojournalism is distinguished from other close branches of photography (e.g., documentary photography, social documentary photography, street photography or celebrity photography) by complying with a rigid ethical framework which demands that the work be both honest and impartial whilst telling the story in strictly journalistic terms. Photojournalists create pictures that contribute to the news media, and help communities connect with one other. Photojournalists must be well informed and knowledgeable about events happening right outside their door. They deliver news in a creative format that is not only informative, but also entertaining. Need and importance, Timeliness The images have meaning in the context of a recently published record of events. Objectivity The situation implied by the images is a fair and accurate representation of the events they depict in both content and tone. Narrative The images combine with other news elements to make facts relatable to audiences. Like a writer, a photojournalist is a reporter, but he or she must often make decisions instantly and carry photographic equipment, often while exposed to significant obstacles (e.g., physical danger, weather, crowds, physical access). subject of photo picture sources, Photojournalists are able to enjoy a working environment that gets them out from behind a desk and into the world.

  • 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.

  • Game Engine Licensing Will Also Cut Down the Development Time, Which Is Good for the Project Funding
    Helsinki School of Economics and Business Administration ABSTRACT Department of Economics - Technology Management and Policy Master’s Thesis July 31, 2000 Jens Wilke SOFTWARE LICENSING IN INTERACTIVE ENTERTAINMENT INDUSTRY Research Problem and Objectives of the Study The objective of the study is to study licensing of software development tools in the interactive entertainment industry. First objective was to find a market model describing the industry. Second objective was to study how well tools like game theory used in industrial economics could be applied in this industry branch. Additional points of interest were company strategies, especially including the aspects of technology leadership and product pricing. A study was conducted in order to find out, if discriminatory pricing practices were used in the industry. Data and Methodology The work began with an overall study of the industry in order to find out the industry characteristics. Many of the assumed facts originate from the openly published interviews of the prominent developers, and some of the information came directly from personal interviews or communication via email. One problem in the study was that pricing and licensing information wasn’t very easily available. This was due to the fact that many companies considered that as sensitive information and weren’t willing to disclose their pricing strategy. At the end of this work a case considering the Finnish company Hybrid Holding Ltd. was conducted. Interviews and studies using several Internet search engines and screenings of Internet news groups were used to study Hybrid’s position in the industry. As the industry is young and in constant change, unfortunately no larger amounts of data could be gathered in order to study the market using statistic tools or to apply models game theory.

  • Core Techniques and Algorithms in Game Programming
    Core Techniques and Algorithms in Game Programming Core Techniques and Algorithms in Game Programming To even try to keep pace with the rapid evolution of game development, you need a strong foundation in core programming techniques-not a hefty volume on one narrow topic or one that devotes itself to API- specific implementations. Finally, there's a guide that delivers! As a professor at the Spanish university that offered that country's first master's degree in video game creation, author Daniel Sanchez-Crespo recognizes that there's a core programming curriculum every game designer should be well versed in-and he's outlined it in these pages! By focusing on time-tested coding techniques-and providing code samples that use C++, and the OpenGL and DirectX APIs-Daniel has produced a guide whose shelf life will extend long beyond the latest industry trend. Code design, data structures, design patterns, AI, scripting engines, 3D pipelines, texture mapping, and more: They're all covered here-in clear, coherent fashion and with a focus on the essentials that will have you referring back to this volume for years to come.

  • 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.

  • Pre Visit Activity 2
    Animation Pre Visit Activity 2. Types of Animation. Basic Types of Animation: 1. • 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, which are 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 onto motion picture film against a painted background by a rostrum camera. 2. • Stop-motion animation is used to describe animation created by physically manipulating real-world objects and photographing them one frame of film at a time to create the illusion of movement. There are many different types of stop-motion animation, usually named after the type of media used to create the animation. • Puppet animation typically involves stop-motion puppet figures interacting with each other in a constructed environment, in contrast to the real-world interaction in model animation. The puppets generally have an armature inside of them to keep them still and steady as well as constraining them to move at particular joints • Clay animation, or Plasticine animation often abbreviated as claymation, uses figures made of clay or a similar malleable material to create stop-motion animation. The figures may have armature or wire frame inside of them, similar to the related puppet animation (below), that can be manipulated in order to pose the figures.
