    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.
