Which of the following can be first used to test for overlap of a curve with the clipping window? a) Edges of the curve b) The centre of the curve c) The bounding rectangle for the curve d) Tangents to the curve
Answer: c Explanation: The bounding rectangle for the curve can be used to test for overlap of the curve with the clipping window. We can use the regular polygon clipping on the basis of the condition that is fulfilled if the bounding rectangle for the curve comes inside the viewing window or not.
