I being use a old nesa patch metaballs, but i what to make a cube in jit.gl.isosurf, and not a sphere

the sphere is being generated from maths in jit.expr, can show me how to make a cube from it instead or give me some points?

sorry, i've re-read my post and it did not make lots of sense here was the question:

A cube is trickier. You'll need to come up with a distance function for a cube. Have a look at this page:

thanks for the answer, however i am struggling to understand how to implement the code from the page into jit.expr,

for making a cube in jit.gl.isosurf you would use a multi plane image with the xy being on the same plane and the z would be the plane number

do i understand this right?

 any more help would be fab!

It'll be tricky to do with jit.expr because you need a length function. With jit.gen it's trivial:
