Where its light falls we lighten colons, where objects blocks the light we darken colons. This level of quality for film animation would take hundreds of years to create on a home computer. Knowlton, and A. The location of the sprite is changed slightly, between each displayed frame, to make the sprite appear to move. Creators drawings either hand drawn pencil to paper or interactively drawn on the computer using different assisting appliances and are positioned into specific software packages. Low bandwidth animations transmitted via the internet e.g. 2D Flash, X3D often use software on the end-users computer to render in real time as an alternative to streaming or preloaded high bandwidth animations. Thus motion capture is appropriate in situations where believable, the realistic behaviour and action is required, but the types of characters required exceed what can be done throughout the conventional costuming. Photorealistic animation would be impractical in this context. A sophisticated graphical user interface may be used to create the animation and arrange its choreography. In most 3D computer animation systems, an animator creates a simplified representation of a character’s anatomy, which is analogous to a skeleton or stick figure . linden, Kenneth C. Zajac, Frank W.

In human and animal characters, many parts of the skeletal model correspond to the actual bones, but skeletal animation is also used to animate other things, such as facial features though other methods for facial animation exist . In most 3D computer animation systems, an animator creates a simplified representation of a character’s anatomy, which is analogous to a skeleton or stick figure . Some, but not all, virtual worlds allow for multiple users. A bone/joint animation system is set up to deform the CPI model e.g., to make a humanoid model walk . Conventional hand-drawn cartoon animation often uses 15 frames/s in order to save on the number of drawings needed, but this is usually accepted because of the stylized nature of cartoons. To trick the eye and brain into thinking they are seeing a smoothly moving object, the pictures should be drawn at around 12 frames per second frame/s or faster a frame is one complete image . Rather than set agars for every frame, they usually set agars at strategic points frames in time and let the computer interpolate or ‘ teen ‘ between them in a process called key framing . For example animation was used in the “Mystery Mardi Gray Shipwreck” documentary to model a remotely operated underwater vehicle ROM and the Mardi Gray archaeological site in 4,000 feet 1220 meters of water in the Gulf of Mexico . 7 Computer animation can also be tailored to mimic or substitute for other types of animation, such as traditional stop-motion animation as shown in Flushed Away or The Lego Film . It can also allow a single graphic artist to produce such content without the use of actors, expensive set pieces, or props.

In most 3D computer animation systems, an animator creates a simplified representation of a character’s anatomy, which is analogous to a skeleton or stick figure . Availability of CPI software and increased computer speeds have allowed individual artists and small companies to produce professional-grade films, games, and fine art from their home computers. Modern computer animation usually uses 3D computer graphics, although 2D computer graphics are still used for stylistic, low bandwidth, and faster real-time renderings . The rendering of architectural spaces without the use of paper and pencil tools is now a widely accepted practice with a number of computer-assisted architectural design systems. 4 Architectural modelling tools allow an architect to visualize a space and perform “walk-throughs” in an interactive manner, thus providing “interactive environments” both at the urban and building levels. 5 Specific applications in architecture not only include the specification of building structures such as walls and windows and walk-throughs, but the effects of light and how sunlight will affect a specific design at different times of the day. 6 Architectural modelling tools have now become increasingly internet-based. Computer graphics software is used to make computer-generated imagery for films, etc. A simple way to generate fractal surfaces is to use an extension of the triangular mesh method, relying on the construction of some special case of a de Rhum curve, e.g. midpoint displacement . 1 For instance, the algorithm may start with a large triangle, then recursively zoom in by dividing it into four smaller Sierpinski triangles, then interpolate the height of each point from its nearest neighbours. 1 The creation of a Brownian surface may be achieved not only by adding noise as new nodes are created, but by adding additional noise at multiple levels of the mesh. 1 Thus a topographical map with varying levels of height can be created using relatively straightforward fractal algorithms. A virtual world is a simulated environment, which allows user to interact with animated characters, or interact with other users through the use of animated characters known as avatars . 18 Virtual worlds are intended for its users to inhabit and interact, and the term today has become largely synonymous with interactive 3D virtual environments, where the users take the form of avatars visible to others graphically. 19 These avatars are usually depicted as textual, two-dimensional, or three-dimensional graphical representations, although other forms are possible 20 auditory 21 and touch sensations for example . Film film seen in cheaters in the United States runs at 24 frames per second, which is sufficient to create the illusion of continuous movement. Computer-assisted Cs computer-generated animation edit To animate means “to give life to” and there are two basic ways that animators commonly do this. Rees, Jan M.K.
