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

I can think of two possibilities:
1: the shape is simply bigger than the container. Try making the 
container bigger.
2: the superellipsoid is inside-out for some reason...use "open" or 
modify the function.

Thanks - I think it was inside out - I changed the function to

    -f_superellipsoid(x,y,z, round, round)
    ^
    |----mulitiplied the thing by -1

and I get the 'proper' result
