MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Correct choice is (a) True Explanation: A polygon can also be clipped by specifying the clipping window.

Detailed explanation-2: -A polygon can also be clipped by specifying the clipping window. Sutherland Hodgeman polygon clipping algorithm is used for polygon clipping. In this algorithm, all the vertices of the polygon are clipped against each edge of the clipping window.

Detailed explanation-3: -We can correctly clip a polygon by processing the polygon bound jry as a whole against each window edge. This could be accomplished by processing all polygon vertices against each clip rectangle boundary in turn.

Detailed explanation-4: -Polygon clipping is an important operation that computers, execute all the time. An algorithm that clips a polygon is rather complex. Each edge ofthe polygon must be tested against each edge of the clipping window, usually a rectangle.

Detailed explanation-5: -The Sutherland–Hodgman algorithm is an algorithm used for clipping polygons.
