What will we be learning Why Study this Course ? & What will we be learning

Basic Terminologies What is Computer Graphics? How does Computer Graphics Differ from Image Processing? Phases of Graphics Pipeline: Imaging = representing 2D images Modeling = representing 3D objects Rendering = constructing 2D images from 3D models Animation = simulating changes over time

Applications Graphs and Charts Computer-Aided Design Virtual Reality Environments Data Visualizations Computer Art Entertainment Industry Image Processing GUI Applications

Types of display architecture Random Scan (/Vector System) Raster Scan Electron beam is deflected only along the path where display is required Image is divided into matrix of pixels and electron beam is scanned sequentially from top to bottom row-wise (& then back to top). Beam intensity is set to reflect pixel intensity
