What does the word animate mean?
Animate means ‘to give life to’.
What is meant by tweening?
The process of drawing a number of frames in between the key-frames is called tweening.
What is stop motion animation?
Animation that involves a model, which is changed small amounts at a time and then repeatedly photographed is called stop motion animation.
Mention the uses of animation?
Animation is widely used in the entertainment industry. It is also at the heart of most computer games for making the graphics more realistic, exciting or engaging. Nowadays animation is increasingly used in education
What are the two types of animation?
Cel Animation and 2. Path Animation
What is exaggeration?
Exaggerating an action can make it seem real. This is especially true in animation. Exaggerating the important elements makes them stand out and brings them closer to the viewer. An example is the case of the eyes of a character coming out of the sockets.
What is flip book animation?
A flip book is a book with a series of pictures varying gradually from one page to the next, so that when the pages are turned rapidly, the pictures appear to animate, simulating motion or some other change.
What is blue screening?
Bluescreening is a technique for shooting live action against a even colored blue background and then replacing the background by another image.
What is morphing?
Morphing is the process of smoothly interpolating between two different images.
What are the six steps of 3D animation?
Creation of 3D animation involves a number of steps: modeling, surface texture, lighting, camera, animating and rendering.
What is mean by Animation?Why we need Animation?
Animate means ‘to give life to’. Animations are created from a sequence of still images. animation is the illusion of motion that is created by displaying a series of images or frames, each one slightly different from the last, over a brief period of time.
Animation can also involve a model, which is changed small amounts at a time and then repeatedly photographed. This type of animation is referred to a stop motion animation. Traditionally animation sequences are created by two types of artists: the lead artists or experts who draw those frames where major changes take place within the sequence, called key-frames, while the assistants draw a number of frames in between the key-frames, a process called tweening. Animation file formats like animated GIF and Flash SWF allow us to view animations on a computer or over the Internet.
Explain the History of Animation.
In the later half of nineteenth century John Marey and Edward Muybridge developed devices that took sequences of photographs of moving objects, and used it to take pictures of galloping horses along a race track in California. In the beginning of the 20th century short animation films were created in which each frame was a separate drawing on paper. The integration between computer graphics and film was first done in the 1970s for creating special effects in feature films like 2001:A space odyssey. Throughout the 80s and 90s companies such as Industrial Light and Magic, Pacific Data Images and Pixar brought ever more sophisticated computer generated imagery to video and film, culminating in the release of ‘Toy Story’ by Pixar in 1995 the first completely computer generated animated feature film.
What are the Uses of Animation?
Animation is widely used in the entertainment industry. It is also at the heart of most computer games for making the graphics more realistic, exciting or engaging. Nowadays animation is increasingly used in education as it provides an excellent way to explain dynamic processes which cannot be easily captured by video, e.g. movement of the pistons of an IC engine. A major use of animation in industrial and scientific applications is to visualize simulation of scientific phenomena, e.g. flight simulations for aircraft and guided missiles.
Explain the Types of Animation.
A cel animation is a term from traditional animation. Cel comes from the word Celluloid. Animation cels are generally layered, one on top of the other, to produce a single animation frame. To depict movement only a portion, typically the foreground cel, can be changed between frames without changing the background cel. (fig 1)(Refer page no342)
An image or collection of images together, called a sprite that moves as an independent object, like a flying bird. The sprite moves along a motion path, typically curved, called splines.
During playback of the animation, the vectors are used to generate the curved path on the screen and the sprite is made to move along the path, using other parameters like speed and duration to control its motion. Path animation is also known as Sprite animation. Usually path animation takes up less disk space to store compared to cel animation because of the vector compact vector representations. (fig 2)(Refer page no343)
2D vs 3D Animation
2D animation programs do not take into consideration the depth of objects and typically depict animated objects on flat surfaces. These are drawn taking into account two coordinate axes along X and Y directions. 3D animation monitors objects by considering space coordinates and usually involves modeling, rendering and adding surface properties, lighting and camera motions. These are more complex than 2D animation and have take into account 3 axes along X,Y and Z. (fig3)(Refer pageno343)
Write a note on Animation on the Web
The WWW in the early 1990s, was initially created to serve hypertext documents but later on support for animated files was included in Web pages.
The uses of animations on the Web are some limitations,
Typically Web based animations involve computer files that must be completely downloaded to the client machines before playback. This can take a long time depending on the file size. A way around this problem is streaming, which is capability of specially formatted animation files to begin playback before the entire file has been completely downloaded.
Another problem with Web animation is that once the animation has been delivered to the user, the user must have the proper helper application or plug-in to display animation.
Write a note on the Shockwave Format
Macromedia’s Shockwave technology for Director was one of the first animation plug-ins for browsers. Shockwave enables Director authors to publish interactive, multimedia content on the Web. To create Shockwave animations for the Web you will need the Director authoring program for Windows. Shockwave animations created on either Windows or Mac can play back in any browser that supports the Shockwave plug-in. To be played via the browser, the Director movie must be saved in the Shockwave format which uses the DCR file extension. It can be inserted in an HTML document using the
