The new isosurface object allows to directly render
surfaces defined by an arbitrary mathematical function.
isosurface {
function { sqrt( pow(x,2) + pow(y,2) + pow(z,2)) - 1 }
contained_by { box { -1, 1 } }
}
generates a simple sphere for example. The surface rendered is an equipotential surface of the specified function. There is a large collection of internal functions available for designing objects. For details see the introductory tutorial or the reference section.
The parametric object makes it possible to directly render a
surface defined by a set of three parametric functions.
