PK_neutral_method_t

typedef int PK_neutral_method_t;

Used in:

PK_FACE_make_neutral_sheet_o_t

This datatype controls the method by which the faces given to the function are
used to construct the neutral sheet.

    PK_neutral_method_mid_offset_c  The function will find the current offset
                                    value of the faces and consider this to be
                                    the thickness between the faces. It will
                                    then make an offset sheet between them
                                    relative to this thickness.

                                    If the faces are not offsets of each other,
                                    or are offsets at different distances, then
                                    this method will fail.

    PK_neutral_method_offset_left_c The function will find the maximum distance
                                    that the 'left_faces' can be offset before
                                    they intersect the 'right_faces' and
                                    consider this to be the thickness between
                                    the faces. It will then offset the
                                    'left_faces' relative to this thickness.

                                    If the minimum distance between the faces
                                    is zero or can not be calculated, this
                                    method will fail.

    PK_neutral_method_medial_c      The function will create a single face
                                    neutral surface such that each point on it
                                    satisfies (1 - p ) D1 = (1 + p) D2.

                                    This allows creation of neutral sheets for
                                    face sets which are not offsets of each
                                    other.
