ContourPlot3d Inside a Sphere Boundary?

Ricardo Canedo, 1

Hello Wolfram Scientists!

Any idea how to do a Region Function "boundary" sphere instead of the default cube shape in Mathematica? I would like to encapsulate a ContourPlot3D smoothly inside of a sphere?

Thank you so much!

I am sorry Ricardo, I don't understand what do you mean with "cut the mesh". Can you show me an example?

I basically need the sphere to cut the mesh. But Ball is not working on my end, unfortunately.

Would it be possible to do this as a Region Function of a Sphere? Does this method cut the mesh smoothly?

Thank you!

Thank you, Ahmed!

The code works well but when I pass on to my code, I get this error:

Show::gtype: Times is not a type of graphics.

Do you know why?

Hi Ricardo

One solution is that you can hide the box around your figure and add a sphere around it using Show. This allows lots of customizations for the surrounding sphere.

Show[Graphics3D[{Opacity[0.3], Sphere[{0, 0, 0}, 4]}], 
 ContourPlot3D[x^3 + y^2 - z^2, {x, -2, 2}, {y, -2, 2}, {z, -2, 2}], Axes -> False, Boxed -> False]
