Class xlifepp::Polygon#

class Polygon : public xlifepp::Surface #

definition of a polygonal geometry in R^3

Polygon constructors are based on a key-value system. Here are the available keys:

_vertices: the vertices defining the polygon, oriented along the boundary (clockwise or counterclockwise)
_nnodes: to define the number of nodes on each edge of the Polygon
_hsteps: to define the local mesh steps on the vertices of the Polygon
_domain_name: to define the domain name
_side_names/_edge_names: to define the side names
_vertex_names: to define the side of side names
_varnames: to define the variable names for print purpose
