Description

本開示の一態様に係る描画装置が提供される。描画装置は、オブジェクトのポリゴンモデル内の複数のポリゴンのうち、Ｍ×Ｍ（Ｍは、４以上の整数）に分割された複数のポリゴンの中で、Ｍ／２×Ｍ／２の範囲に属する複数のポリゴン毎に連続した番号が割り当てられた場合、ポリゴンに割り当てられた番号順に、ポリゴンの頂点に連続した番号が割り当てられることで得られた複数の頂点を示す頂点データを記憶する記憶部を有する。 A drawing device according to one aspect of the present disclosure is provided. The drawing device is a polygon that belongs to a range of M/2 x M/2 among multiple polygons divided into M x M (M is an integer greater than or equal to 4 ) in the polygon model of the object. When consecutive numbers are assigned to each of multiple polygons , a storage unit is provided that stores vertex data indicating the multiple vertices obtained by assigning consecutive numbers to the vertices of the polygons in the order of the numbers assigned to the polygons. have

Claims

Among the multiple polygons in the polygon model of the object, each of the multiple polygons belonging to the range of M/2×M/2 among the multiple polygons divided into M×M (M is an integer of 4 or more ) having a storage unit that stores vertex data indicating a plurality of vertices obtained by assigning consecutive numbers to the vertices of the polygon in the order of the numbers assigned to the polygons when consecutive numbers are assigned to the polygons;
drawing device.

further comprising a drawing section;
