指定されたデフォーマに対してデンベロープ
ウェイトを設定し、ウェイトを平均化します。ウェイトを平均化したくない場合、Envelope.SetDeformerWeights2
メソッドを使用します。
}デフォーマのウェイトは、ジオメトリのインデックス順ではなく、クラスタのインデックス順に渡す必要があります。指定されたジオメトリインデックスと一致するクラスタインデックスを取得するには、Envelope.Elementsと同時にClusterElementCollection.FindIndexを使用します。
Envelope.SetDeformerWeights( Deformer, [Weights] ); |
| パラメータ | タイプ | 詳細 |
|---|---|---|
| デフォーマ | X3DObjectまたはエクスプレッション | デフォーマオブジェクト |
| ウェイト | DoubleのArray | ウェイトの配列。エンベロープによって影響を受けるポイントごとに1 つのウェイト。 |
