How to do this efficiently?

Hi,
I have a number of (>30k) 3D curved lines stored in a cell. They are of different lengths. What would be the best way to find out whether each one goes through a rectangular bounding box? With a for loop, it seems to be slow.
Thanks.

Do you have a working solution based on a for loop?
I don't think the for loop can be the problem. Do you have a growing variable in the loop?

Please post your code. Otherwise suggestions for improvements are based on guessing.
