MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Abhishek Mishra. Answer: d Clarification: In polygon clipping, first the polygon is clipped against the left edge of the polygon window to get new vertices of the polygon. So, it is the top left which is clipped first.

Detailed explanation-2: -The first of all polygons are stored in original form. Then clipping against left edge done and output is stored. Then clipping against right edge done, then top edge. Finally, the bottom edge is clipped.

Detailed explanation-3: -(1) Out-In-If the first vertex is outside the window boundary and the second vertex is inside, both the intersection point of the polygon edge with the window boundary and the second vertex are added to the output vertex list.

Detailed explanation-4: -Line Clipping | Set 1 (Cohen–Sutherland Algorithm)

Detailed explanation-5: -3. Which of the following part of a polygon is considered in a polygon clipping algorithm? Explanation: Polygon clipping is a process in which we only consider the part which is inside the view pane or window. We will remove or clip the part that is outside the window.
