Hi all

I've just started playing around with isosurfaces, only without much
success.
Here's a snippet of my code:

#local round = 0.2;

isosurface {
    function{f_superellipsoid(x,y,z, round, round)}
    contained_by { box { -1, 1 } }
    pigment{White}
}

I would expect this to produce a round box, but all I see is the container
box with some artefacts.
My aim to produce a round box as would appear if using the superellipsiod
primitive - I'm using an isosurface though because I want to later deform it
with a noise function.

I'm guessing there's a simple solution I've overlooked in the manual.

thanks in advance
jim
