I am interested in plotting the 3D region which is the intersection of functions of the form :
- f1( x, y, z, u) = 0
- f2( x, y, z, u) = 0
- f3( x, y, z, u) = 0
- gmin <= g(u) <= gmax
Note that there is a free variable u apart from the 3 coordinate vars - x,y,z
assume that it is NOT possible to simplify/eliminate the above into 3equations in x,y,z.
Is there a way this region can be plotted in Mathematica using a combination of RegionPlot3D and Boole functions?
