PK_BCURVE_clamp_t

typedef int PK_BCURVE_clamp_t;

Used in:

PK_BCURVE_create_spline_2_o_t
PK_BCURVE_create_spline_o_t

This datatype controls whether to apply a clamp when creating a bcurve.

It has values:

    PK_BCURVE_clamp_no_c          The resultant bcurve will not be clamped.
    PK_BCURVE_clamp_constant_c    If a subsequence of 'positions' lie in the
                                  same clamp plane, then the resultant spline
                                  will also remain coincident with that clamp
                                  plane between those positions.
    PK_BCURVE_clamp_extreme_c     The resultant bcurve will have the same
                                  property as with PK_BCURVE_clamp_constant_c.
                                  Furthermore, if a supplied position p is such
                                  that the previous and next positions lie on
                                  the same side of a clamp plane passing
                                  through p, then the resultant spline will
                                  also lie on the same side of that clamp plane
                                  between the adjacent positions.
