Study Notes
Introduction to Computer Graphics
- Computer graphics combines display, storage, and manipulation of images for visual system representation.
- The discipline relies on programming to create drawings, charts, and pictures using a computer.
- Graphics are composed of numerous pixels, forming the basis of digital image representation.
Applications of Computer Graphics
- Used across various fields: science, engineering, medical sciences, business, entertainment, art, education, and training.
- Facilitates effective information presentation through visual means, enhancing understanding in diverse areas.
Objectives of Computer Graphics
- Aims to generate realistic or useful images on a computer.
- Focus on realism for applications like special effects in films and data visualization for practical usefulness.
- Images produced can include realistic scenes, statistical diagrams (e.g., histograms, pie charts), and software interfaces.
Impacts of Computer Graphics Development
- Revolutionized media, leading to advancements in animation, film, and the video game industry.
- Encompasses several elements: image data representation and manipulation, technologies for image creation, produced images, and the study of digital synthesis and manipulation of visual content.
Interactive Computer Graphics
- Users can control and modify images in interactive graphics, enabling a two-way communication with the computer.
- Input devices allow users to make changes to the produced images, enhancing user engagement and experience.
Components of Interactive Graphics
- Composed of three key components:
- Frame Buffer or Digital Memory
- Monitor (similar to a television but without tuning and receiving electronics)
- Display Controller or Video Controller, which conveys frame buffer contents to the monitor.
History of Computer Graphics
- 1950: Ben Laposky creates the first graphic images using an oscilloscope for waveform artwork.
- 1951: MIT produces Whirlwind, a mainframe computer with a CRT to visualize incoming aircraft based on radar data.
