Hi all.

What am I doing wrong:

#declare meshfunc = function{f_mesh1(x,y,z,0.2,0.2,0.3,0.4,0.5)}

isosurface
{
        function {meshfunc(x,y,z)}
        threshold 1

        contained_by
        {
                box {-1,1}
        }         
        
        material{texture{pigment{color White}}}
}

All this does is produce a white cube, sized 1x1x1. I can put any values
from very small to large (0.01 to 10) into the function line, but it still
only produces a white cube, instead of a mesh.

What is wrong with my parameters or code structure here?

Thanks!

All that's happening is that with "threshold 1" the thickness of each
thread is larger than the contained_by box, so the box gets completely
filled. Try setting the threshold to a much smaller value, like 0.01

You will then also need to increase max_gradient.

Thanks! That fixed it - I decreased the threshold and that did the trick.
