Hi, does anyone have any thoughts or solutions to my volume problem:

Given two arbitrary ellipses in 3 space I am trying to develop an

efficient test to determine whether or not any arbitrary point

is contained within the volume defined by the two ellipses.

Im not being very precise about the definition of the enclosing

volume, but its usually a tube-like structure with ellipsoid caps,

not necessarily parallel to each other.

Thanks for any help.

Rob.
