PK_proj_connect_t

typedef int PK_proj_connect_t;

Used in:

PK_CURVE_project_o_t

This datatype specifies how to connect disjoint components of the projection.

It has the values:

    PK_proj_connect_none_c       Do not connect at all.

    PK_proj_connect_side_c       Connect if possible with projections on
                                 faces which are side on when viewed in the
                                 projection direction.

    PK_proj_connect_all_c        Connect if possible with side and hidden
                                 faces.

    PK_proj_connect_side_all_c   Project to all faces which are side on when
                                 viewed in the projection direction, even if
                                 they do not connect disjoint components.

    PK_proj_connect_hidden_all_c Project to all faces which are side on or
                                 hidden when viewed from the projection
                                 direction, whether they connect disjoint
                                 components of the projection or not. This
                                 value is not supported if 'use_max_dist' is
                                 set to PK_proj_max_dist_whole_c.

Note that if 'use_max_dist' is set to PK_proj_max_dist_whole_c then connect
projections must lie entirely within 'max_dist' of the input curves.
