Key Concepts of Computer Graphics

Computer graphics/CG are any drawing/image/media, usually movies and pictures that are created on the computer screen through the use of hardware and software. Computer graphics are often referred to as computer-generated anything. An example of a computer graphic is given in this picture.Computer Graphics 

Why Computer Graphics is Important

Some key points are given below to understand the importance of the basics of Computer Graphics. This is a basic overview of Computer graphics study important.

  • Understanding information: Visualization is the basics for dealing with complex data.
  • Improved communication with computers: Graphical and audio interfaces are helpful to understand anything in groups.
  • Better product designs: Designers can explore more things in less time with the help of computer graphics.
  • More economical designs: Design databases can be tested electronically, reducing dependence on the complex.
  • Better Manufacturing: Design databases can be transmitted to robots for manufacturing.

Subfields of Computer Graphics

According to many experts, there are eight fundamental areas of computer graphics. These are discussion able.

Mathematical Structures
Spaces, points, vectors; dust, curves, surfaces, solids.
Modeling
Description of objects and their attributes, including:
  • Primitives (e.g. pixels, polygons)
  • Intrinsic Geometry
  • Attributes (color, texture)
  • Connectivity (scene graphs)
  • Dynamics (motion, morphing)

Techniques for object modeling, including:

  • Polygon meshes
  • Patches
  • Solid Geometry
  • Fractals
  • Sweeps
  • L-grammars
  • Particle systems
User Interfaces
Human interfaces, input-output devices, color theory, workstations, interactive techniques, dialog design, animation.
Graphics Software
Graphics APIs; paint, CAD, draw and animation software; modeling and image databases.
Graphics Hardware
Input output devices, specialized graphics card for specialized architectures.
Viewing
Abstract to device coordinate transformations, the synthetic camera, windows, viewports, clipping and etc.
Rendering
Realism, physical modeling, ray tracing, radiosity, visible surface determination, transparency, translucency, refraction, reflection, shading, shadows, surface and texture mapping, etc.
Image Processing
Image description, storage, transformations, filtering, enhancement, pattern recognition, edge detection, object reconstruction.
