Question: Analog of discont=true in plot3d?

Is there some sort of analog of  option  discont=true  in  plot3d?  Can I remove these vertical cylindrical surfaces in the following example? They correspond to the zeros of the denominator:

plot3d((x^2+sin(x))/(y^2+cos(x)), x = -7 .. 7, y = -5 .. 5, view = [-7 .. 7, -6 .. 6, -1 .. 7], numpoints = 50000, scaling = constrained, axes = normal);

plots[implicitplot](y^2+cos(x), x = -7 .. 7, y = -5 .. 5, scaling = constrained, numpoints = 5000);

 

 

Please Wait...
