You just beat me to the punch Ron :-)
The docs for MegaPov give the correct syntax for the named isosurface functions, but
MegaPov also requires
contained_by {}
in the isosurface definition.
e.g.
isosurface { function { "rounded_box" <.2> }
contained_by { }
pigment { Red}
}
In testing this with MegaPov I found a bug has been added since SuperPatch.
The size of the rounded box is determined by the size of contained_by !
With no value for contained_by you get a rounded box of unit sides. But;
contained_by { box {0,4}}
makes the rounded box of sides 4!
Ah well, it just goes to keep us on our toes :-)
