UNIT I INTRODUCTION 9
Survey of computer graphics, Overview of graphics systems – Video display devices, Raster scan
systems, Random scan systems, Graphics monitors and Workstations, Input devices, Hard copy
Devices, Graphics Software; Output primitives – points and lines, line drawing algorithms, loading the frame buffer, line function; circle and ellipse generating algorithms; Pixel addressing and object
geometry, filled area primitives.

UNIT II TWO DIMENSIONAL GRAPHICS 9
Two dimensional geometric transformations – Matrix representations and homogeneous coordinates,
composite transformations; Two dimensional viewing – viewing pipeline, viewing coordinate reference
frame; widow-to-viewport coordinate transformation, Two dimensional viewing functions; clipping
operations – point, line, and polygon clipping algorithms.

UNIT III THREE DIMENSIONAL GRAPHICS 10

tables- Plane equations - Polygon meshes; Curved Lines and surfaces, Quadratic surfaces; Blobby
objects; Spline representations – Bezier curves and surfaces -B-Spline curves and surfaces.
TRANSFORMATION AND VIEWING: Three dimensional geometric and modeling transformations –
Translation, Rotation, Scaling, composite transformations; Three dimensional viewing – viewing
pipeline, viewing coordinates, Projections, Clipping; Visible surface detection methods.

UNIT IV ILLUMINATION AND COLOUR MODELS 7
Light sources - basic illumination models – halftone patterns and dithering techniques; Properties of
light - Standard primaries and chromaticity diagram; Intuitive colour concepts - RGB colour model -
YIQ colour model - CMY colour model - HSV colour model - HLS colour model; Colour selection.

UNIT V ANIMATIONS & REALISM 10
ANIMATION GRAPHICS: Design of Animation sequences – animation function – raster animation –
key frame systems – motion specification –morphing – tweening. COMPUTER GRAPHICS
REALISM: Tiling the plane – Recursively defined curves – Koch curves – C curves – Dragons –
space filling curves – fractals – Grammar based models – fractals – turtle graphics – ray tracing.
