Study Notes
Computer Graphics Overview
- Graphics are defined as sketches, drawings, or networks that pictorially represent information.
- Computer graphics are used to manipulate and create images composed of pixels, displayed on a computer.
- The graphics area in an application is used to create and edit images.
Types of Computer Graphics
- Raster Graphics (Bitmap): Use pixels to draw images. A sequence of smaller pixels creates the image, often a lot of pixels together.
- Vector Graphics: Use mathematical formulas to draw shapes, lines, and objects.
Raster Graphics vs Vector Graphics
- Raster images are made of pixels, easily distorted if enlarged.
- Vector images are made of lines and shapes which maintain quality when enlarged.
Applications of Computer Graphics
- Education and Training: Computer models help students understand physical, financial, and economic systems.
- Biology: Used to display molecular structures, helping scientists understand their shape and function.
- Computer-Generated Maps: Used in urban planning and transportation engineering.
- Architecture: Architects use interactive graphics systems to explore alternative design solutions.
- Presentations: Bar charts, line graphs, and pie charts to summarize data.
- Computer Art: Used for commercial art including television and advertising commercials.
- Entertainment: Used in creating motion pictures, music videos, and television shows.
- Visualization: Used in diverse fields like scientific research, engineering, and medicine to analyze large amounts of data visually.
- Educational Software: Used in educational software to create computer-aided instruction.
- Printing Technology: Graphics are used in printing technology and textile design.
Graphics Systems
- Input Devices: Keyboard, mouse, tablet, touch screen, data glove, camera, light pen, joystick, joyswitch, trackball, spaceball, microphone, speech recognizer. Logical devices include string, locator, pick, choice, valuator, stroke.
- Processors: Process instructions, control the flow of data between input and output devices.
- Memory: Stores data temporarily.
- Frame Buffer: A device which receives data from the processor and stores data to be displayed on an output device, like a screen.
- Output Devices: CRT display, LCD display, plasma display, printer, plotter, e-paper, hologram generator, film recorder, sound recorder, speaker, robot arm.
Graphics Primitives
- Pixel: A single point of light in a graphics display. The foundation from which raster images are formed.
- Line: A fundamental building block of graphs, charts, drawings, and plans. Straight lines are particularly important in computer graphics.
- Polygon: A closed area made up of straight or curved lines, filled with color. An image composed of polygons can be complex and three-dimensional.
- Display File: A series of uncorrelated data like histograms or bivariate arrays.
Display Control
- Controls the image view based on desired angle and magnification.
- Converts data in the frame buffer into 0s and 1s, displayed on the monitor. This occurs at a rate of 30 times per second, to create an ongoing visual display.
- Changes to pictures require adjusting the contents of the frame buffer to reflect the changes.
Graphics Software
- A set of programs or parts of a program to manipulate visual images on a computer.
- Points: Basic units of graphics used to construct more complex shapes.
- Polygons: Construct three-dimensional images.
Viewport and Text
- Text: Can be in two and three dimensions, inserted at any position on the image, according to specified style criteria.
- Viewport: Rectangular viewing area of the computer screen, defines the portion of the larger image that's visible.
Graphic Communications
- An umbrella term for the creative and production processes involved in creating any kind of communication using imagery.
Major Applications
- Computer Art: Creating fine and commercial art, includes animations, paint packages used in drawing shapes and specifying motion of objects.
- Computer Aided Drawing: Designing buildings, vehicles, etc.; focuses on precision and clarity in drawings to aid in accurate manufacturing.
- Education: Creating computer models to teach concepts and fundamentals in a clear, visual manner.
- Training: Using specialized systems (simulators) to train candidates quickly, effectively.
- Visualization: Displaying visual data and insights in an easily understandable way.
- Image Processing: Editing and enhancing images for use in various applications.
- Machine Drawing: Creates precise drawings for various parts and machines, critical for safe manufacturing.
- Graphical User Interface: Creates user-friendly interfaces using images, icons, menus to ensure easy interactions with computer systems.
Additional Applications
- Entertainment: Creating cartoons, animation films, video games, and television shows.
- Medical Imaging: Generating images to assist in medical diagnosis and understanding.
- Image Processing: Editing and improving images, for various uses.
- Graphical Interface: Creating user-friendly interfaces.
Fundamentals Techniques
- Advanced Shading Methods: Improves visual richness of images.
- Lighting: Increases realism using light sources and effects.
- Texture Mapping: Adds surface details to textures and shapes.
- Translucency: Creates semi-transparent elements, enhancing realism.
- Atmospheric Effects: Simulates atmosphere and light scattering.
