PK_SURF_split_t

typedef int PK_SURF_split_t;

Used in:

PK_SURF_fix_self_int_o_t

This datatype indicates which direction to prefer splitting surfaces when
fixing self-intersecting surfaces. It has the values:

    PK_SURF_split_prefer_u_c    Allow splitting in both directions, but prefer
                                splits in the u parametric direction.

    PK_SURF_split_prefer_v_c    Allow splitting in both directions, but prefer
                                splits in the v parametric direction.

    PK_SURF_split_only_u_c      Only allow splitting in the u parametric
                                direction.

    PK_SURF_split_only_v_c      Only allow splitting in the v parametric
                                direction.
