enum bs3_curve_form {
  bs3_curve_open_ends,
  bs3_curve_closed_ends,
  bs3_curve_periodic_ends,
  bs3_curve_unknown_ends
}

Classifies the end conditions of a 3D B-spline curve.

Values:

bs3_curve_open_ends: The curve has open ends.
bs3_curve_closed_ends: The curve has position continuity but not tangent continuity.
bs3_curve_periodic_ends: The curve closes smoothly, and there is tangent as well as position continuity around the ends.
bs3_curve_unknown_ends: unknown end conditions.
