It may be one of those quirky sort of things, like which math is done
first. I.e. x+y*z or z*y+x or x+(y*z) or... Didn't mean to make math out to
be folly by saying that, sorry :-)
Anyway, I've seen it someplace that it's a good idea to do a box thusly:
-4,4 instead of 4,-4 so that the lower values are put first. Either that or
I'm dreaming it up. Why such a thing would cause a break in it I haven't a clue.

| Why do I get a surface here:
|
| isosurface {
| function {sqr(x)+sqr(z)-sqr(y)}
| contained_by { box { -4,<4,0,4> } }
| pigment {rgb y}
| }
|
| but not here:
|
| isosurface {
| function {sqr(x)+sqr(z)-sqr(y)}
| contained_by { box { <4,0,4>,-4 } }
| pigment {rgb y}
| }
|
