To provide a computer program which suppresses the Moire.SOLUTION: A computer program causes a computer to execute: processing of generating a voxel structure constituted by a voxel with the determined RGB value and opacity corresponding to each pixel of each of a plurality of x-y plane images captured at a prescribed interval along a Z-axis direction, processing of correcting the RGB value of the target voxel on the basis of the RGB value of the neighboring voxel located in the vicinity of the target voxel whose opacity of the voxel structure is a prescribed value； processing of generating a 3D texture image constituted by the voxel with the corrected RGB value； processing of generating a post-conversion 3D texture image by performing prescribed conversion to the 3D texture image； processing of setting the laminated square in which the squares on the X-Y coordinate surface of the three-dimensional space are arranged in the Z-axis direction； and processing of generating a rendering image on the basis of the RGB value obtained by alpha blending the RGB value of the voxel of the post-conversion 3D texture image corresponding to the X-Y coordinates of the square on the sight line in parallel with the Z-axis direction from the prescribed view point.SELECTED DRAWING: Figure 9【課題】モアレを抑制するコンピュータプログラムを提供する。【解決手段】ｚ軸方向に沿って所定間隔で撮像された複数のｘｙ平面画像それぞれの各画素に対応し、ＲＧＢ値及び不透明度が定められたボクセルで構成されるボクセル構造体を生成し、ボクセル構造体の不透明度が所定値である対象ボクセルの近傍に位置する近傍ボクセルのＲＧＢ値に基づいて、対象ボクセルのＲＧＢ値を補正し、ＲＧＢ値が補正されたボクセルで構成される３Ｄテクスチャ画像を生成し、３Ｄテクスチャ画像に所定の変換を行って変換後３Ｄテクスチャ画像を生成し、３次元空間のＸＹ座標面上の四角形をＺ軸方向に並べた積層四角形を設定し、所定の視点からＺ軸方向に平行な視線上の四角形のＸＹ座標に対応する変換後３Ｄテクスチャ画像のボクセルのＲＧＢ値をアルファブレンディングして得られたＲＧＢ値に基づいてレンダリング画像を生成する。【選択図】図９
