PK_pick_approximate_t

typedef int PK_pick_approximate_t;

Used in:

PK_BODY_pick_topols_o_t

The 'pick_approx' option can be set to one of the following values:

PK_pick_approximate_yes_c           Curves are approximated by a sequence
                                    of straight line chords.

PK_pick_approximate_no_c            Accurate curve geometry is used when
                                    checking whether the ray intersects
                                    a face.

The default value is 'PK_pick_approximate_yes_c' and it is recommended for
interactive picking operations.
