.SH NAME
\fBlevel_set\fP - compute a level set from a function
.\" skip: @findex  level_set
.\" skip: @clindex field
.\" skip: @clindex geo
.PP
.SH SYNOPSIS

geo level_set (const field& fh);
.SH DESCRIPTION

Given a function \fBfh\fP defined in a domain \fBLambda\fP,
compute the level set defined by {x in Lambda, fh(x) = 0}.
This level set is represented by the \fBgeo\fP class.
.SH OPTIONS

The option class \fBleve_set_option_type\fP
controls the slit of quadrilaterals into triangles
for tridimensional intersected surface and also the
zero machine precision, \fBepsilon\fP.
