Hi!

I just noticed something strange - did not made much testing by now, but
perhaps someone can confirm this behaviour. I'm using MegaPov 0.6a. (Maybe
it's already fixed in 0.7?)
The following isosurface renders fine as it is.
But if I change the contained_by to box {<-14.5,1.3,30>,<0,1.5,6>} it
disappears

isosurface {
        function {(
                          ((x-5)*(x-5)+(z*z)/4-144)                    //
[12*12=144]
                        )
                       }
        method 2
        max_gradient 40
        max_trace 2
        accuracy 0.0025
        contained_by{box {<-14.5,1.5,30>,<0,1.3,6>}}

        texture{ T_Wood8
                   }
    }

My fault?
