I can plot the intersection line of two surfaces f$f$,g $g$ by using:
Contourplot3D[f[xContourPlot3D[
f[x, y,z]==0 z] == 0,
MeshFunctions -> {Function[{x, y, z, f}, f[x, y, z] - g[x, y, z]]}
]
But I need to do some calculations based on the intersection line. Or I need 100 (for example) group data of (x,y,z)$(x, y, z)$ on the line. How can I do this?
