Raster animation is created by displaying a sequence of raster images rapidly to create the illusion of motion. Each raster image is stored as a bitmap in system memory and contains information about individual pixels that make up the image. By refreshing the frame buffer with a new bitmap, raster animation is created. There are two main types - traditional using sprite sheets and modern using programming languages. Raster animation provides more realistic images than vector animation but requires more memory and processing power. It is used for applications like 3D/2D animation, games, and movies.
Animation is the process of generating moving images using computer graphics. It involves creating a storyboard to outline the motion sequences, defining the objects participating in the action, and specifying key frames that define the starting and ending points of transitions. Intermediate frames are generated between key frames through tweening or in-betweening to give the appearance that one image evolves smoothly into the next and create the illusion of motion.
This document discusses the process of computer animation. It begins by defining computer animation and listing some common applications like video games, cartoons, and mobile phones. It then outlines the main steps for designing an animation sequence, which include storyboard layout, object definitions, key frame specifications, and generating in-between frames. Key frames define the starting and ending points of movements, while in-betweens create the illusion of smooth motion between key frames. Raster animation and general animation functions are also briefly discussed.
The document discusses animation design and control. Animation functions include a graphics editor, key frame generator, in-between generator, and standard graphics routines. The graphics editor allows designing and modifying object shapes. Scene description in animation specification includes object and light positioning, photometric and camera parameters. Action specification involves motion paths for objects and cameras. Standard graphics routines include viewing transformations and rendering operations. Key-frame systems generate in-betweens from user-specified key frames. Parameterized systems allow specifying object motion characteristics as part of object definitions. Scripting systems define object specifications and animation sequences through a user-input script.
a spline is a flexible strip used to produce a smooth curve through a designated set of points.
Polynomial sections are fitted so that the curve passes through each control point, Resulting curve is said to interpolate the set of control points.
The document discusses the 2D viewing pipeline. It describes how a 3D world coordinate scene is constructed and then transformed through a series of steps to 2D device coordinates that can be displayed. These steps include converting to viewing coordinates using a window-to-viewport transformation, then mapping to normalized and finally device coordinates. It also covers techniques for clipping objects and lines that fall outside the viewing window including Cohen-Sutherland line clipping and Sutherland-Hodgeman polygon clipping.

Random scan displays and raster scan displaysSomya Bagai
Raster scan displays work by sweeping an electron beam across the screen in horizontal lines from top to bottom. As the beam moves, its intensity is turned on and off to illuminate pixels and form an image. The pixel values are stored in and retrieved from a refresh buffer or frame buffer. Random scan displays draw images using geometric primitives like points and lines based on mathematical equations, directing the electron beam only where needed. Raster scans have higher resolution but jagged lines, while random scans produce smooth lines but cannot display complex images. Both use a video controller and frame buffer in memory to control the display process.

The document discusses various techniques for tiling a plane including monohedral and dihedral tilings using regular polygons. It also discusses recursively defined fractal curves like the Koch curve and Dragon curve which are generated by repeating a simple process to produce self-similar patterns. Grammer based models for simulating plant growth using graftals are also covered.
Anti-aliasing is a technique used to reduce aliasing, which makes curved or slanted lines appear jagged when displayed on a lower resolution output device like a monitor. Aliasing occurs because the device lacks enough resolution to smoothly represent curved lines. Anti-aliasing works by adding subtle color changes around lines, which causes jagged edges to blur together when viewed from a distance. There are several anti-aliasing techniques, including increasing the display resolution, area sampling to shade pixels based on the area covered by thickened lines, and post-filtering by generating a higher resolution virtual image and averaging it down.
There are three main methods for generating characters using software: the stroke method, vector/bitmap method, and starbust method. The stroke method uses a sequence of line and arc drawing functions defined by starting and end points. The starbust method uses a fixed pattern of 24 bit line segments to represent characters. The bitmap method stores characters as arrays of 1s and 0s representing pixels, allowing for variable font sizes by increasing the array size. All the methods can create aliased characters, and the starbust method requires extra memory to store the 24 bit segment codes.
This document discusses line attributes in computer graphics, including line type (solid, dashed, dotted), width, caps (butt, round, projecting square), joins (miter, round, bevel), and color. It describes how to set these attributes using functions like setLinetype(), setLinewidthscaleFactor(), and setPolylineColourIndex(). Lines can also be displayed using pen or brush options which have properties like shape, size, and patterns.
This document discusses fractals and their use in computer graphics. It defines fractals as self-similar geometric objects that can model natural forms. Common fractals include the Koch snowflake and fractal trees & ferns, which are generated through an iterative process. The document also describes how fractals can be used to procedurally generate terrain by applying random mid-point displacement.
This document discusses character attributes. It seems to focus on describing personality traits or qualities that define a person's character. In just a few words, it aims to capture the essence of someone's character.
The Sutherland-Hodgman algorithm clips polygons by clipping against each edge of the clipping window in a specific order: left, top, right, bottom. It works by testing each edge of the polygon against the clipping window boundary and either keeping or discarding vertices based on whether they are inside or outside the window. The algorithm results in a clipped polygon that only includes vertices and edge intersections that are inside the clipping window.
The document discusses the 3D viewing pipeline which transforms 3D world coordinates to 2D viewport coordinates through a series of steps. It then describes parallel and perspective projections. Parallel projection preserves object scale and shape while perspective projection does not due to foreshortening effects. Perspective projection involves projecting 3D points along projection rays to a view plane based on a center of projection. Other topics covered include vanishing points, different types of perspective projections, and how viewing parameters affect the view volume and object positioning in the view plane coordinates.
The document discusses different line and area attributes that can be used to display graphics primitives. It describes parameters like line type (solid, dashed, dotted), width, color, and fill style (solid, patterned, hollow). It explains how these attributes can be set using functions like setLineType() and setInteriorStyle(). Pixel masks and adjusting pixel counts are used to properly render dashed lines at different angles. Color can be represented directly or indirectly via color codes mapped to an output device's color capabilities. Patterns for filled areas are defined via 2D color arrays.

The Cohen-Sutherland algorithm divides the plane into 9 regions and uses 4-bit codes to encode whether each endpoint of a line segment is left, right, above, or below the clipping window. It then uses the endpoint codes to either trivially accept or reject the line segment, or perform clipping by calculating the intersection point of the line with the window boundary and replacing the outside endpoint. The main steps are to assign codes to endpoints, AND the codes to check for trivial acceptance or rejection, clip by replacing outside endpoints if needed, and repeating for other line segments.
After an image has been segmented into regions ; the resulting pixels is usually is represented and described in suitable form for further computer processing.
There are two main types of projections: perspective and parallel. In perspective projection, lines converge to a single point called the center of projection, creating the illusion of depth. In parallel projection, lines remain parallel as they are projected onto the view plane. Perspective projection is more realistic but parallel projection preserves proportions. Perspective projections can be one-point, two-point, or three-point depending on the number of principal vanishing points. Orthographic projections use perpendicular lines while oblique projections are at an angle. Common parallel projections include isometric, dimetric, trimetric, cavalier and cabinet views.

This document discusses various techniques for image segmentation. It describes two main approaches to segmentation: discontinuity-based methods that detect edges or boundaries, and region-based methods that partition an image into uniform regions. Specific techniques discussed include thresholding, gradient operators, edge detection, the Hough transform, region growing, region splitting and merging, and morphological watershed transforms. Motion can also be used for segmentation by analyzing differences between frames in a video.
Animation is created by displaying a series of images rapidly to create the illusion of movement. It works due to phenomena like persistence of vision and phi phenomenon. There are different types of animation including 2D animation which uses static images manipulated on a 2D plane, 3D animation which adds depth and movement along the z-axis, and stop motion animation which manipulates physical objects frame by frame. A storyboard is used in planning animation to visualize scenes, characters, and motion through a comic-style presentation before beginning production.
This document defines animation and describes different animation techniques. Animation is created by displaying a sequence of images rapidly to give the appearance of motion. It can be created using traditional methods by photographing drawings one frame at a time or digitally using software. Effective animation typically uses a frame rate of 24 frames per second. Key animation principles include persistence of vision and phi phenomenon. Popular animation techniques include cel animation and tweening used in Disney films as well as Flash and 3D animation. Animations can be saved in formats like GIF, QuickTime, AVI, and MPEG for display on websites, in multimedia projects and films.

It also discusses four types of digital animation and provides key terminology used in animation including keyframes, tweening, onion skinning, frame rate, and aspect ratio.
Raster scanning is a process used in television and computer graphics where an image is captured and reconstructed by systematically scanning across it in horizontal lines from top to bottom. Each line, called a scan line, is transmitted as an analog signal or divided into discrete pixels. Pixels are stored in a refresh buffer and then "painted" onto the screen one row at a time, with the beam returning to the left side during horizontal retrace and to the top left for vertical retrace between frames. Raster scanning provides realistic images but at the cost of lower resolution compared to random scanning systems.

Early animation processes involved displaying still images in rapid succession to create the illusion of continuous motion. The frame rate needed to be fast enough, such as the 30 frames per second standard for television. Early animation devices like the zoetrope and modern techniques at Disney involved drawing each frame by hand. Computer animation allows defining keyframes with software generating intermediate frames, reducing the labor. Storyboards provide a visual script to plan animation scenes before production.

This document discusses various topics related to computer animation including its applications, design of animation sequences, animation functions, raster animations, computer animation languages, key frame systems, motion specifications, morphing, and tweening. It describes computer animation as the process of generating animated images using computers and discusses animation software functions for creating and processing animations. Animation techniques like raster operations, general purpose programming languages, direct and goal-directed motion specifications, kinematics, dynamics, and physically based modeling are also summarized.
Raster scan displays work by sweeping an electron beam across the screen one row at a time from top to bottom, turning the beam's intensity on and off to create illuminated spots. This allows the display to store an entire frame of picture data in a frame buffer memory. Raster scanning is well suited for realistic scenes like television and refreshes at 60-80 frames per second. Random scan displays direct the electron beam only where a picture element needs to be drawn, storing pictures as a set of line drawing commands rather than a frame buffer. It is better for applications like plotters that draw individual lines.
Computer graphics involves drawing pictures on screens through programming and manipulating data. The primary output device is a video monitor, which uses a cathode ray tube. In a raster scan display, an electron beam sweeps across the screen line by line to display pixels stored in a refresh buffer. This avoids screen flicker. A random scan display directs the electron beam only where needed for high resolution line drawings, but is limited to simple images. Raster graphics systems use a video controller to access a frame buffer in memory and refresh the screen.
