I'm using the code

ContourPlot3D[
  NumericQ[
    Integrate[
      Piecewise[
        {{Exp[-1/(1 - x^4 - y^4)]*
            Exp[I*ω*10*({Cos[ϕ], Sin[θ]} - {Cos[π/2], Sin[π/2]})], 
          Sqrt[x^2 + y^2] < 1}, 
        {0, Sqrt[x^2 + y^2] >= 1}}, 
        PerformanceGoal -> "Speed"], 
      {x, -2, 2}, {y, -2, 2}]], 
  {ϕ, 0, 2*π}, {θ, 0, 2*π}, {ω, -2, 2}, 
  PerformanceGoal -> "Speed", MaxRecursion -> 0]

I had the parameters set higher before, namely {x,-10,10}, etc., and I didn't use the MaxRecursion nor PerformanceGoal, but after four days of running I still had no result. Even now, I have had it running for most of the day and still no result.

Is this normal? Can I speed it up?

Edit: Note that the piecewise function I'm trying to plot is:

$$\frac{e^{10i\omega}}{40\pi}\int_{-\infty}^{\infty}\int_{-\infty}^{\infty}\exp\left(-\frac{1}{1-x^{4}-y^{4}}\right)\exp\left(10i\omega\left(\begin{pmatrix} \cos\phi\\\sin\theta \end{pmatrix}-\begin{pmatrix} \cos\frac{\pi}{2}\\\sin\frac{\pi}{2} \end{pmatrix}\right)\begin{pmatrix} x\\y \end{pmatrix}\right)\,dx\,dy, \text{ if }\sqrt{x^2+y^2}<1\text{ and }0\text{ otherwise}.$$
