Definition

template<typename R>
class CGAL::Convex_hull_d< R >

Deprecated:: This package is deprecated since the version 4.6 of CGAL. The package PkgTriangulations should be used instead.

An instance C of type Convex_hull_d<R> is the convex hull of a multi-set S of points in \( d\)-dimensional space. We call S the underlying point set and \( d\) or dim the dimension of the underlying space. We use dcur to denote the affine dimension of S. The data type supports incremental construction of hulls.

The closure of the hull is maintained as a simplicial complex, i.e., as a collection of simplices. The intersection of any two is a face of both (The empty set if a facet of every simplex). In the sequel we reserve the word simplex for the simplices of dimension dcur. For each simplex there is a handle of type Simplex_handle and for each vertex there is a handle of type Vertex_handle. Each simplex has 1 + dcur vertices indexed from 0 to dcur; for a simplex s and an index i, C.vertex(s,i) returns the i-th vertex of s. For any simplex s and any index i of s there may or may not be a simplex t opposite to the i-th vertex of s. The function C.opposite_simplex(s,i) returns t if it exists and returns Simplex_handle() (the undefined handle) otherwise. If t exists then s and t share dcur vertices, namely all but the vertex with index i of s and the vertex with index C.index_of_vertex_in_opposite_simplex(s,i) of t. Assume that t exists and let j = C.index_of_vertex_in_opposite_simplex(s,i). Then s = C.opposite_simplex(t,j) and i = C.index_of_vertex_in_opposite_simplex(t,j).

The boundary of the hull is also a simplicial complex. All simplices in this complex have dimension dcur - 1. For each boundary simplex there is a handle of type Facet_handle. Each facet has dcur vertices indexed from 0 to dcur - 1. If dcur> 1 then for each facet f and each index i, 0 <= i < dcur, there is a facet g opposite to the i-th vertex of f. The function C.opposite_facet(f,i) returns g. Two neighboring facets f and g share dcur - 1 vertices, namely all but the vertex with index i of f and the vertex with index C.index_of_vertex_in_opposite_facet(f,i) of g. Let j = C.index_of_vertex_in_opposite_facet(f,i). Then f = C.opposite_facet(g,j) and i =C.index_of_vertex_in_opposite_facet(g,j).

Template Parameters

R	must be a model of the concept `ConvexHullTraits_d`.

Iteration Statements

forall_ch_vertices( \( v,C\)) \( \{\) the vertices of \( C\) are successively assigned to \( v\) \( \}\)

forall_ch_simplices( \( s,C\)) \( \{\) the simplices of \( C\) are successively assigned to \( s\) \( \}\)

forall_ch_facets( \( f,C\)) \( \{\) the facets of \( C\) are successively assigned to \( f\) \( \}\)

Implementation

The implementation of type Convex_hull_d is based on [2] and [1]. The details of the implementation can be found in the implementation document available at the download site of this package.

The time and space requirements are input dependent. Let \(C_1\), \(C_2\), \(C_3\), \(\ldots\) be the sequence of hulls constructed and for a point \( x\) let \( k_i\) be the number of facets of \( C_i\) that are visible from \( x\) and that are not already facets of \( C_{i-1}\).

Then the time for inserting \( x\) is \( O(dim \sum_i k_i)\) and the number of new simplices constructed during the insertion of \(x\) is the number of facets of the hull which were not already facets of the hull before the insertion.

The data type Convex_hull_d is derived from Regular_complex_d. The space requirement of regular complexes is essentially \( 12(dim +2 )\) bytes times the number of simplices plus the space for the points. Convex_hull_d needs an additional \( 8 + (4 + x)dim\) bytes per simplex where \( x\) is the space requirement of the underlying number type and an additional \( 12\) bytes per point. The total is therefore \( (16 + x)dim + 32\) bytes times the number of simplices plus \( 28 + x \cdot dim\) bytes times the number of points.

Types
Note that each iterator fits the `Handle` concept, i.e. iterators can be used as handles. Note also that all iterator and handle types come also in a const flavor, e.g., `Vertex_const_iterator` is the constant version of `Vertex_iterator`. Const correctness requires to use the const version whenever the convex hull object is referenced as constant. The `Hull_vertex_iterator` is convertible to `Vertex_iterator` and `Vertex_handle`.
