QUESTION 1

Why polygonal models favored (over NURBS for instance) as assets in computer games? Explain in two or more paragraphs. Include references. (301 words)

Polygon Modeling method is the most common method of modeling used at present times in Films, Television and especially for Computer/Video games. This is because its convenient, efficient and easy to work with.There are points in 3D space, called vertices, are connected by line segments to form a 'polygonal mesh'. 3D Models in present moment are constructed as textured polygonal models, because they are flexible and therefore computers can render them quickly and efficiently. It has many efficient tools. Polygons are easy for a game engine to understand better comparing it with …show more content…

More recent hole-filling methods focus more on the appearance of the fill - naive triangulation of the hole may not appear smooth with its immediate surroundings hole boundary, progress has been made in two main directions. Besides edges forming the boundary of a gap or hole, the input model may contain non-manifold polygonal edges shared by more than one or two polygons. Non-manifold connectivity often represents membranes interior to the model or redundant pieces of geometry, while some formula separates these models into manifold patches possibly with overlapping boundaries and others eliminate the membranes by representing them as double-sided walls and removing the overlapping polygons.

QUESTION 3

Name three significant advances in computer graphics technology from 1960 to the present day? Briefly discuss each, stating why they were crucial and how they have influenced contemporary CG creation. Include references.(315 Words)

The phrase “Computer Graphics” was coined in 1960 by William Fetter, a graphic designer for Boeing. Art Director made the first computer model of a human body ("Boeing Man"). He
