DRAWING PROGRAM, DRAWING METHOD AND DRAWING DEVICE

PROBLEM TO BE SOLVED: To reduce the number of points to be drawn and perform drawing of a point group appropriately.SOLUTION: A computer is caused to execute processing including: adjusting, when a three-dimensional point group is projected onto a projection plane, a size of each cell so that a projected point is less than or equal to a predetermined number in each cell defined on the projection plane; selecting, after the adjustment, a single point for a cell containing a projected single point; selecting, for a cell containing a plurality of projected points, one point from the plurality of points; and drawing the point selected by the selection on the projection plane.SELECTED DRAWING: Figure 4 【課題】描画する点数を削減でき、点群の描画を適切に行えるようにする。【解決手段】３次元の点群を投影面に投影した場合、投影された点が前記投影面に定義された各セルに所定数以下となるように前記各セルのサイズを調整し、前記調整後に、投影された単数の点が含まれるセルについては前記単数の点を選択し、投影された複数の点が含まれるセルについては前記複数の点から１の点を選択し、前記選択により選ばれた点を前記投影面に描画する、処理をコンピュータに実行させる。【選択図】図４
