Suppose you want to store line segments in an R-tree. If a line segment is not parallel

Question:

Suppose you want to store line segments in an R-tree. If a line segment is not parallel to the axes, the bounding box for it can be large, containing a large empty area.

• Describe the effect on performance of having large bounding boxes on queries that ask for line segments intersecting a given region.

• Briefly describe a technique to improve performance for such queries and give an example of its benefit.
