btol_edge_algs::btol_edge_algs ( ) [private]

vsol_box_2d btol_edge_algs::bounding_box ( vcl_vector< vtol_edge_2d_sptr > & edges ) [static]

Get the bounding box for a set of edges.

Computes the bounding box for a set of edges.

vtol_vertex_2d_sptr btol_edge_algs::closest_vertex	(	vtol_edge_2d_sptr const &	e,
		const double	x,
		const double	y
	)		`[static]`

Find the vertex closest to the specified position.

find the vertex closest to the given position and return it.

void btol_edge_algs::edge_2d_erase	(	vcl_vector< vtol_edge_2d_sptr > &	edges,
		vtol_edge_2d_sptr const &	e
	)		`[static]`

A convenient erase interface.

a bit more convenient interface for finding edges than messing with iterators.

	)		`[static]`

use static methods.

Splits e at v and returns the two edges e1, e2, which are incident at v.

If v is not within btol_edge_algs::tol (user-settable) of a point on edge e then false is returned, and e is not split

	)		`[static]`

Replace va on edge e by vb.

Replaces va by vb on edge e.
