To render a virtual object that is a permeation object at a high speed while reducing discomfort in its appearance.SOLUTION: An image processing system comprises attribute determination means for determining the permeation attribute of a virtual object, setting means for setting a virtual viewpoint to observe the virtual object, relations determination means for determining the physical relationship among each of a plurality of polygons representing the virtual object and the virtual viewpoint, determination means for determining if a surface of the polygon is to be rendered for each polygon of the plurality of polygons based on the physical relationship among the permeation attribute of the virtual object, the virtual viewpoint, and the polygon, and rendering means for rendering the surface of the polygon that is determined to be rendered by the determination means.SELECTED DRAWING: Figure 2 【課題】 透過物体である仮想物体を、見た目の違和感を低減しつつ高速に描画する。【解決手段】 画像処理装置に、画像処理装置に、仮想物体の透過属性を判定する属性判定手段と、前記仮想物体を観察する仮想視点を設定する設定手段と、前記仮想物体を表現する複数のポリゴンの各々と前記仮想視点との位置関係を判定する関係判定手段と、前記複数のポリゴンの各ポリゴンについて、前記仮想物体の透過属性と、前記仮想視点と当該ポリゴンとの位置関係とに基づいて、当該ポリゴンの面を描画対象とするかを判断する判断手段と、前記判断手段により描画対象とすると判断されたポリゴンの面を描画する描画手段とを備える。【選択図】 図２
