Principles of Computer Graphics

Salient Features:- Computer Graphics Basics: origin of graphics working of interactive graphics Random scan methods Raster scan methods Pixels and frame buffer color display techniques Graphics Primitives Display file structure. Output primitives: Points & lines Line drawing DDA algorithm Bresenhams line drawing algorithm circle generation algorithm Character generation text display filling polygon. Display description: Line and polygon clipping viewing algorithms- Windows and viewpoints windowing zooming and planning Homogeneous co-ordinate Two dimensional and three dimensional transformation Concatenation. Interactive Graphics: CRT graphical input devices Graphical input techniques event handling input functions Segmented display file: Segments functions for segmenting the display file posting and unposting a segment segment naming schemes appending to segment. Three dimensional graphics: Geometric models Introduction to realism perspective depth Introduction to shading and illumination: Phong shading Gouraud shading Projection Types of projection. Hidden Surface elimination & Curves and surfaces.
