In mathematics, a Kochanek–Bartels spline or Kochanek–Bartels curve is a cubic Hermite spline with tension, bias, and continuity parameters defined to change the behavior of the tangents. Given ''n'' + 1 knots, :p0, ..., p''n'', to be interpolated with ''n'' cubic Hermite curve segments, for each curve we have a starting point p''i'' and an ending point p''i''+1 with starting tangent d''i'' and ending tangent d''i''+1 defined by : : where... Setting each parameter to zero would give a Catmull–Rom spline. The (source code found here ) of Steve Noskowicz in 1996 actually describes the impact that each of these values has on the drawn curve: The code includes matrix summary needed to generate these splines in a BASIC dialect. == External links == * * 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Kochanek–Bartels spline」の詳細全文を読む スポンサード リンク
