Detailed Description

Structure of a convex.

This class is not to be manipulated by itself. Use pconvex_structure and the functions written to produce the convex structures from classicals convexes (simplexes, polygonals ...). The reason is that there is no need for having more than one convex structure for the same type of convex.

Member Function Documentation

nb_points_of_face()

short_type bgeot::convex_structure::nb_points_of_face ( short_type  i ) const

inline

Number of vertices of a face.

Parameters

i	the face number.

Definition at line 99 of file bgeot_convex_structure.h.

ind_points_of_face()

const convex_ind_ct& bgeot::convex_structure::ind_points_of_face ( short_type  i ) const

inline

Give an array of the indexes of the vertices of a face.

The indexes are "local" to the convex.

Parameters

i	the face number.

Definition at line 105 of file bgeot_convex_structure.h.

ind_common_points_of_faces()

const convex_ind_ct & bgeot::convex_structure::ind_common_points_of_faces

(

const std::vector< short_type > &

ftab

)

const

Give an array of the indexes of the vertices at the intersection of a set of faces.

The indexes are "local" to the convex.

Parameters

i	the face number.

Definition at line 56 of file bgeot_convex_structure.cc.

ind_dir_points()

const convex_ind_ct& bgeot::convex_structure::ind_dir_points ( ) const

inline

Return "direct" points indexes.

These are the subset of points that can be used to build a direct vector basis. (rarely used)

Definition at line 116 of file bgeot_convex_structure.h.

faces_structure()

const convex_structure_faces_ct& bgeot::convex_structure::faces_structure ( ) const

inline

Give a pointer array on the structures of the faces.

faces_structure()[i] is a pointer on the structure of the face i.

Definition at line 121 of file bgeot_convex_structure.h.

ind_dir_points_of_face()

ref_convex_ind_ct bgeot::convex_structure::ind_dir_points_of_face ( short_type  i ) const

inline

Return "direct" points indexes for a given face.

Parameters

i	the face number.

Definition at line 126 of file bgeot_convex_structure.h.

is_product()

bool bgeot::convex_structure::is_product ( pconvex_structure *  pprod1 = 0, pconvex_structure *  pprod2 = 0  ) const

inline

Return true if the convex structure is indeed a direct product of two convex structures.

Parameters

pprod1	the first sub-structure (optional)
pprod2	the second sub-structure (optional)
