bool A48::Vertex::is_bdry (   )  [inline]

Returns true if the vertex belongs to mesh boundary, else return false. Returns: boolean type (true or false). Definition at line 38 of file vertex.h. References A48::Hedge::edge(), A48::Edge::is_bdry(), and s_. Referenced by A48::Mesh::simplify(). { return s_->edge()->is_bdry(); };

bool A48::Vertex::is_inbase (   )  [inline]

Returns true if the vertex belongs to base mesh, else return false. The base mesh represents the resolution level 0 of the mesh 4-8. Returns: boolean type (true or false). Definition at line 44 of file vertex.h. References level(). { return (level() == 0); };

bool A48::Vertex::is_weld (  Face *  exclude = NULL  )  [inline]

Returns true if the vertex is a weld vertex, else return false,. A weld vertex is a vertex that can be simplified. Parameters: exclude  Face pointer. Returns: boolean type (true or false).
