plotparam takes two main arguments,
a list of three
expressions of two variables and the list of these variable names
where each variable name may be replaced by variable=interval
to specify the range of the parameters.
It accepts an optional argument to specify
the discretization steps of the parameters u and v with
ustep=... and vstep=....
plotparam([f(u,v),g(u,v),h(u,v)],[u,v]) draws the surface defined by the
first argument : x=f(u,v),y=g(u,v),z=h(u,v), where u and v
ranges default to the graphic configuration.
