vtol_extract_topology_vertex_node Struct Reference

#include <vtol_extract_topology.h>

List of all members.

Detailed Description

A node in the graph of vertices.

The links correspond to edges between the vertices. Each vertex is located at the corner of the pixel.

Member Function Documentation

static const unsigned null_index vtol_extract_topology_vertex_node::VCL_STATIC_CONST_INIT_INT_DECL

(

unsigned(-2)

)

[static]

Null index value.

A vertex with an index value >= this value does not correspond to a node in the graph.

static const unsigned done_index vtol_extract_topology_vertex_node::VCL_STATIC_CONST_INIT_INT_DECL

(

unsigned(-1)

)

[static]

"Processed" index value.

This is used to indicate that the boundary edge following went through a vertex.
