It is very flexible and can be This function is used to assign values to individual quantities for a domain. It is very flexible and can be used with many data types: a statement of the form \code{domain.set\_quantity{name, x}} can be used to define a quantity having the name \code{name}, where the other argument \code{x} can \begin{itemize} \item a number \item a list of numbers \item a Numeric array \item a function (e.g. see the samples introduced in Chapter 2) \item a number in which case all vertices in the mesh gets that for the quantity in question. \item a list of numbers or a Numeric array ordered the same way as the mesh vertices. \item a function (e.g.\ see the samples introduced in Chapter 2) \item an expression composed of other quantities and numbers, arrays, lists (for example, a linear combination of quantities) \item the name of a file from which the data can be read \item a geospatial dataset \item a geospatial dataset (See ?????) \end{itemize} The output generated by \anuga may be viewed by means of the visualisation tool \code{swollen}, which takes the \code{sww} file output by \anuga and creates a visual representation of the data. Examples may be seen in Figures XX and YY. To view an \code{sww} file with \code{swollen} in the Examples may be seen in Figures \ref{fig:bedslopestart} and \ref{fig:bedslope2}. To view an \code{sww} file with \code{swollen} in the Windows environment, you can simply drag the icon representing the file over an icon on the desktop for the \code{swollen} executable file (or a shortcut to it). Alternatively, you can operate \code{swollen} \end{tabular} \section{utilities/polygons} Could do now. \section{utilities/polygons} \begin{classdesc}{Polygon_function}{regions, default = 0.0, geo_reference = None} \begin{funcdesc}{populate_polygon}{polygon, number_of_points, seed = None, exclude = None} \indexedcode{populate_polygon} Module: \code{utilities.polygon} \begin{funcdesc}{point_in_polygon}{polygon, delta=1e-8} \indexedcode{point_in_polygon} Module: \code{utilities.polygon} \begin{funcdesc}{inside_polygon}{points, polygon, closed = True, verbose = False} \indexedcode{inside_polygon} Module: \code{utilities.polygon} \begin{funcdesc}{outside_polygon}{points, polygon, closed = True, verbose = False} \indexedcode{outside_polygon} Module: \code{utilities.polygon}
