KOSEKOMA 0191 - An isosurface is a three-dimensional analog of an isoline. It is a surface that represents points of a constant value (e.g. pressure, temperature, velocity, density) within a volume of space; in other words, it is a level set of a continuous function whose domain is 3D-space: x^2+y^2+z^2+cos(4*x)+cos(4*y)+cos(4*z)-0.2=0
