While the x and z dimensions of the contained_by box are obviously up to me,
how do I work out what (sensible) values to use for the y dimensions of, for
example, the following:
#declare MountFunc = function{"ridgedMF" <0.9, 2, 5, 0.75, 2>}
#declare MBase =
isosurface{
function { y - MountFunc(x,0,z) * min(2, max(0.125,(sqr(x/5) +
sqr(z/5)))) }
eval
max_gradient 50
contained_by{box{<-20,-1,-20>,<20,15,20>}}
texture{MBaseTex}
}
