This document provides an overview of computer graphics, including definitions, algorithms, applications, and references. It defines computer graphics as the technology dealing with designs and pictures created using computers. Key algorithms discussed include Bresenham's line drawing algorithm, the DDA algorithm, and the mid-point circle drawing algorithm. Applications mentioned are GUIs, weather maps, satellite imaging, medical imaging, and engineering drawings.

4. What is Computer Graphics?
The definition of computer graphics is the technology that deals with designs and
pictures on computers.
In other words, Computer graphics is an art of drawing pictures, lines, charts, etc. using
computers with the help of programming.

5. Short note on Computer Graphics
• The term computer graphics refers to "almost everything on computers that
is not text or sound”
• Refers to creation, Storage and manipulation of pictures and drawing using a
digital computer.
• Computer graphics is responsible for displaying art and image data
effectively and meaningfully to the consumer.
• Computer graphics development has had a significant impact on many types
of media and has revolutionized animation, movies, advertising, video
games, and graphic design in general.

6. Algorithms
Some algorithms for Computer Graphics:
DDA algorithm:
Digital Differential Analyzer (DDA)algorithm is the simple line
generation algorithm. It is a faster method for calculating pixel positions
than the direct use of equation y = mx + b.
Bresenham’s Line Drawing algorithm:
An efficient algorithm to render a line with pixels. The long dimension is
incremented for each pixel, and the fractional slope is accumulated.

7. Mid Point Circle Drawing Algorithm:
We use this algorithm to calculate all the perimeter
points of the circle in the first octant and then print
them along with their mirror points in the other octants.

8. Figures

10. Remarks
we can create our own creation by using computer graphics. It is a quick way for
visualize the charts, the numbers, images.

11. Applications
• Computer graphics user interfaces (GUIs) − A graphic, mouse-oriented
paradigm which allows the user to interact with a computer.
• Weather Maps − Real-time mapping, symbolic representations.
• Satellite Imaging − Geodesic images.
• Photo Enhancement − Sharpening blurred photos.
• Medical imaging − MRIs, CAT scans, etc. - Non-invasive internal examination.
• Engineering drawings − mechanical, electrical, civil, etc. - Replacing the
blueprints of the past.
• Even More
