The code is an isosurface fond on MathMod software.
Translated in SDL :


—————————————————————————————————————————————————
#declare R = function { k*(x/(x*x+y*y+z*z)) }

#declare PSkeletalGraph = function { 
cos(x)+cos(y)+cos(z)+(51/100)*(cos(x)*cos(y)+cos(y)*cos(z)+cos(z)*cos(x))+(147/100) 
}

#declare InvertPSkeletalGraph = function {
  PSkeletalGraph(R(x,y,z),R(y,x,z),R(z,y,x))
  }

// --- Isosurface
#declare Fxyz = function (x,y,z) { InvertPSkeletalGraph(x,y,z) }

isosurface {
	function { Fxyz(x,y,z) }
	max_gradient 800 // 3500
	contained_by { box { -L, +L } }
	pigment { Yellow }
	}
