I'd like to have a Manipulate that shows a cross-section of a 3D Graphic, with the position of the cross section determined by the Manipulate controls. It seems to me this should be possible with the new graphics functionality in version 10.
Turns out taking a cross-section of a Ball centered at {x,y,z} with radius r onto the plane z = zz can be done with a rule:
Ball[{x, y, z}, r] -> Ball[{x, y}, Sqrt[Max[r^2 - (zz - z)^2, 0]]
Hi,
