Basics of Computer Graphics
- 1. An Introduction to Computer Graphics Mohit Raj Panday By
- 2. Introduction • Computer graphics is an art of drawing pictures on computer screens with the help of programming or through any software. • It involves computations, creation, and manipulation of data. • In other words, we can say that computer graphics is a rendering tool for the generation and manipulation of images. • The primary output device in a graphical system is the video monitor. The main element of a video monitor is the Cathode Ray Tube (CRT). • There are two ways (Random scan and Raster scan) by which we can display an object on the screen.
- 4. Computer graphics user interfaces (GUIs) • The graphical user interface (GUI), is a type of user interface that allows users to interact with electronic devices through graphical icons and visual indicators, instead of text-based user interfaces, typed command labels or text navigation. • A graphic, mouse-oriented paradigm which allows the user to interact with a computer. 4
- 5. 5 Weather Maps • Real-time weather mapping and its symbolic representations.
- 6. 6 Cartography • Cartography is the study and practice of making maps. Combining science, aesthetics, and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively.
- 7. 7 Satellite Imaging/Geodesy • Satellite geodesy is geodesy by means of artificial satellites — the measurement of the form and dimensions of Earth, the location of objects on its surface and the figure of the Earth's gravity field by means of artificial satellite techniques. It belongs to the broader field of space geodesy.
- 8. Photo Enhancement • Sharpening blurred photos. • Changing Effects on photos. • Converting B/W photos into Colored. • Image manipulation. 8
- 9. 9 Medical imaging • MRI scans : Magnetic Resonance Imaging • CAT scans: Computerized axial tomography scans • Ultrasound Scan • Other Non-invasive internal examination.
- 10. Engineering drawings • Mechanical, electrical, civil, etc. - Replacing the blueprints of the past. 10
- 11. 11 Art • Computers provide a new medium for artists. • Software like CorelDraw provide this type of functionality.
- 12. Training • Flight simulators, computer aided instruction, etc. 12
- 13. 13 Entertainment • Movies and games.
- 14. Simulation and modeling • Replacing physical modeling and enactments 14
