FCurveKey.Interpolation

説明

F カーブセグメントの右側の補間タイプを（siFCurveKeyInterpolation列挙型の値の 1 つとして）設定したり、戻したりします。

F カーブセグメント補間は、標準F カーブ(タイプが siStandardFCurve のもの)にのみ適用されます。他のすべての F カーブタイプでは、siConstantKeyInterpolation 値が戻されます。

siDefaultInterpolation値を使用してキー補間を設定しようとした場合、その操作は無視され、C++でS_FALSE が戻されます。

詳細については、Softimage ユーザ ガイドの「F カーブの補間および外挿」を参照してください。
