The Cohen-Sutherland algorithm divides the two-dimensional space in how many regions?

Computer Graphics - Quiz(MCQ)

Correct Answer : 9

Explanation : If the line is neither a visible case nor an invisible case, then it will be considered to be the clipped case.

The Cohen-Sutherland algorithm will divide the 2D space into nine regions.

All nine regions are assigned codes. Each code is of 4 bits. If both endpoints of the line have end bits zero, then the line is considered to be visible.
