Hi :

I have plot that's given by:

spiral = SphericalPlot3D[\[Phi], {\[Theta], 0, Pi}, {\[Phi], 0, 3 Pi},
BoxRatios -> {1, 1, 1}, PlotRange -> {{-10, 10}, {-10, 10}, {-10, 10}}];
line = ParametricPlot3D[{-3*t, 16*t, 1*t}, {t, -2, 2},
AxesLabel -> {"x", "y", "z"}, PlotStyle -> {Thickness[0.006], Blue}];
Show[spiral, line]

This is a line that pierces a spiral. (The spiral looks like a snail's shell.)
How can I calculate the intersection point coordinates that are shown in the plot?


Thanks,

Bill

PS. I'm using Mathematica 6.0.1.
