| Zusammenfassung: | To provide a surface write field conversion device which converts a surface write field so as to obtain a natural rendering result according to a posture change of a three-dimensional model.SOLUTION: A surface write field conversion device 1 includes a directional vector conversion unit 20 which converts a directional vector to a directional vector after a posture change by using a posture conversion matrix indicating rotational conversion of a normal vector n of a three-dimensional model in a local position following the posture change, and a directional conversion matrix indicating rotational conversion from a direction of the normal vector n before the posture change to a directional vector contained in the surface write field L.SELECTED DRAWING: Figure 5
【課題】三次元モデルの姿勢変化に応じて自然なレンダリング結果となるようにサーフェスライトフィールドを変換するサーフェスライトフィールド変換装置を提供する。【解決手段】サーフェスライトフィールド変換装置１は、姿勢変化に伴う三次元モデルの局所における法線ベクトルｎの回転変換を示す姿勢変換行列と、姿勢変化前の法線ベクトルｎの方向からサーフェスライトフィールドＬに含まれる方向ベクトルの方向への回転変換を示す方向変換行列とを用いて、方向ベクトルを姿勢変化後の方向ベクトルに変換する方向ベクトル変換部２０、を備える。【選択図】図５ |
