Description
これは、太陽が障害物に出たり入ったりする瞬間にフレアモデルが描画される。フレアモデルでは、X,Y,Zの座標比が〔1,1、r+4〕、a=2|0.5−r|で定義される。図2に示すように、フレアモデル18Aは発光体モデル10より突出し、発光体の拡散光に対して強調されて描画される。
Claims (3)
- 仮想三次元空間内に配置された画像モデルを、前記仮想三次元空間内に設定された視点の視点座標系における透視投影面上に透視投影して得られる二次元画像を画像処理回路により生成する画像処理方法であって、
前記画像処理回路は、
前記仮想三次元空間に配置される発光体を、発光源座標から前記投影面に向かった方向に距離成分を持ち、かつ、前記投影面側において前記方向に放射状に拡がる形状を形作る面からなるモデルによって構成し、
当該オブジェクトに前記発光体の中心像とこれから放出される拡散光像とを描くようにし、
前記発光体が、前記視点側に位置する障害物により、隠れる割合を示す食分に応じて、前記モデルの始点より終点までの距離を変化させるようにした画像処理方法。 - 前記画像処理回路は、前記食分に応じて、前記オブジェクトの透明度を変化させてなる請求項1記載の画像処理方法。
- 請求項1記載の画像処理の手順をコンピュータに実行させるためのプログラム。
