Starting from i.e. the following 3d plot:
d = RandomReal[1, {100, 3}];
ListPlot3D[d]
Is it possible to extract points that lay along an arbitralyarbitrarily oriented line, i.e. like this:
Show[{ListPlot3D[d], Graphics3D[Line[{{0, -.5, 1}, {0.5, 1, 1}}]]}]
?
EDIT: Z values of the plot along the line projected onto the x-y plane
