  • 11. PRESENTATION GRAPHICS
    • Presentation Graphics is representing descriptions and facts using graphs.
    • Various Graphs such as Piechart, bargraphs line charts are used.
    • Used to summarize financial, statistical, mathematical, scientific data etc.
  • 12. VISUALIZATION
    • Scientific Visualization
    • Business Visualization
    • Computer graphics makes vast quantities of data accessible.
    • Numerical simulations frequently produce millions of data values.
    • Similarly, satellite-based sensors amass data at rates beyond our abilities to interpret them by any other means than visually.
    • Mathematicians use computer graphics to explore abstract and high-dimensional functions and spaces.
    • Physicists can use computer graphics to transcend the limits of scale.
  • 13. IMAGE PROCESSING
    • Manipulating images with a computer
    •  
    • Image processing generally involves three steps:
      • Import an image with an optical scanner or directly through digital photography.
      • Manipulate the image in some way. This stage can include image enhancement and data compression.
    • For example: Image processing can be used to reduce the noise (that infernal spec that comes from nowhere) in an image.
      • Output the result. The result is the image altered in some way.

  • 14. EDUCATION AND TRAINING
    • Computer Graphics is almost used in every field to teach and train
    • Medicine
    • Human Anatomy Models
    • Engineering
    • Animated Models : Explaining the working of different models
    • Fashion Designing
    • Designing and Creating new Patterns
