I'm having a problem trying to plot a 3D energy band structure. Having a function of 3 variables (energy) for example:
f[x_,y_,z_]:= Cos[x]+Cos[y]+Cos[z]
What i need is simple to evaluate f along the paths:
x[t_] := {t, 0, 0}
y[t_] := {1, t, 0}
z[t_] := {1, 1, t}
r[t_] := {t, t, t}
And plot all the graphics aligned (image as an example)
I found a solution very similar to this problem Here, but the package built there is for the 2D problem.
