Draw functions on Plot3D












2












$begingroup$


I have a 2D function $f(x,z)$ which I render with Plot3D. In the plot, on top of the surface, I want to plot 1D functions at $f(0, z)$, $f(100, z)$ and $f(200, z)$.



So far I only have this:



um = 1;



Potential[V0_, k_, w_, x_, z_] := V0*(Sin[k z]^2)*Exp[(-2 x^2)/w^2]



mfx = 

  Function[{x, y, z}, Evaluate[D[Potential[1, (2 π)/(0.725 um ), 200 um, x, z], x]]];



Plot3D[Potential[1, (2 π)/(0.725 um ), 200 um, x, z], 

   {x, -500 um, 500 um}, {z, -1.1 um, 1.1 um}, 

   PlotRange -> Full, 

   AxesLabel -> {x, z}, 

   PlotPoints -> 50, 

   MeshFunctions -> {mfx}, 

   Mesh -> {{0}}, 

   MeshStyle -> {{Red}}, 

   Boxed -> False, 

   Axes -> {True, False, False}, 

   PlotStyle -> Cyan]


And I get this:

This only works for the $x = 0$ bit though.. how can I also add lines at $x = 100, 200$?

          You have to indicate the Mesh as a List



          um = 1;
          
Potential[V0_, k_, w_, x_, z_] := V0*(Sin[k z]^2)*Exp[(-2 x^2)/w^2]
          
Plot3D[Potential[1, (2 π)/(0.725 um), 200 um, x, z], 
          
  {x, -500 um, 500 um}, {z, -1.1 um, 1.1 um}, 
          
  PlotRange -> Full,
