Holds optional controls for closing gaps at tolerant vertices in the loop.

Used in:

PK_LOOP_close_gaps

The options structure contains the following options:

'gap_in_3_space'   Option for controlling model space gaps at tolerant
                   vertices in the loop.

                   Permitted values are:
                        PK_LOOP_3_space_gap_close_c
                        PK_LOOP_3_space_gap_no_c

                   If the value is set to PK_LOOP_3_space_gap_close_c,
                   model space gaps at tolerant vertices of the loop will be
                   closed where possible by modifying the SP-curves.
                   Geometry attached to accurate edges will not be modified.

                   The default value is PK_LOOP_3_space_gap_close_c.

'gap_in_2_space'   Option for controlling parameter space gaps at tolerant
                   vertices in the loop.

                   Permitted values are:
                        PK_LOOP_2_space_gap_no_c
                        PK_LOOP_2_space_gap_minimise_c
                        PK_LOOP_2_space_gap_close_cu_c
                        PK_LOOP_2_space_gap_close_all_c

                   If the value is set to PK_LOOP_2_space_gap_minimise_c, the
                   parameter space gaps between adjacent fin geometries will
                   be minimised where possible by transforming the SP-curves
                   to meet in the same period. This option only comes into
                   effect when the surface attached to loop's face is periodic.

                   If the value is set to PK_LOOP_2_space_gap_close_cu_c, the
                   parameter space gaps between adjacent fin geometries will
                   be closed where possible by extending or retrimming
                   the SP-curves to meet within the tolerance specified by
                   'tol_in_2_space'.

                   If the value is set to PK_LOOP_2_space_gap_close_all_c,
                   the parameter space gaps between adjacent fin geometries
                   will be closed where possible by extending or retrimming
                   the SP-curves to meet within the tolerance specified by
                   'tol_in_2_space' and by reparameterising the underlying
                   surface if required.

                   The default value is PK_LOOP_2_space_gap_no_c.

'tol_in_2_space'   tolerance value for identifying parameter space gap at
                   tolerant vertices in the loop. The default value is 1.0e-06.

'trim_fin_geom'    if the value is set to PK_LOOP_trim_geom_yes_c then that
                   portion of the fin's SP-curve that lies outside the
                   bounds of the fin will be discarded.
