Hello,

Is there an expert over there, who would able to add, using mathematica:
a text "abc" at position "1,1,2" and
a text "def" at position "2,2,4", by :

keeping same looking at the original plot (no changing of ratio x, y, z)
keeping Show (because i need to put other stuff inside)

Show[Plot3D[-8*(x*x+y*y)+(x*x+y*y)*(x*x+y*y),{x,-3,3},{y,-3,3},BoxRatios-=
>{3,4,2},Mesh->None,ClippingStyle->None,RegionFunction->Function[{x,y,z},=
x^2+y^2<9 && x<2],Boxed->False,Axes->True,AxesOrigin->{0,0,-16.5}]

thank you
