typedef struct PK_replace_help_points_s PK_replace_help_points_t;



This structure is part of the PK_FACE_replace_surfs_o_t options
structure. It contains the help point positions to be used to
calculate the new geometries of the specified topologies.
For each topology, its closest geometry solution to its related
help point is prefered to any possible other.
The topologies must be of the same type, all edges or all vertices.

Used in:

PK_FACE_change_o_t
PK_FACE_replace_surfs_o_t

Description of fields:



'n_topologies'      Number of topologies to help modify. Length of the
                    'topologies' and 'positions' arrays.
                    The default value is 0.


'topologies'        Array of the topologies to help modify. All the topologies
                    in this array must be of the same type, edges or vertices.
                    The array default value is NULL.


'positions'         Array of the user-provided help positions for
                    the specified topologies. The array default value is NULL.
