Hi,
I'm trying to solve Antenna in the Cinoc Mountains from UVa.
I don't know how to find the intersection between a segment and a cone. Can anyone point me in the right direction?
Thanks.

The cone can be nicely intersected with parametrized line: x=x1+t*(x2-x1) . And the segment is parametrized line of form above with t in [0,1]. I hope this helps
