Abstract

　インタラクティブ用途のＣＧ処理にも適用でき、かつ、入力ポリゴンモデルの頂点データのロードに関するメモリアクセス量を低減する。 　ポリゴンを描画することでコンピュータグラフィックス画像を生成する画像生成装置（１００）であって、ポリゴンを構成する頂点の頂点データのうち、座標データをロードする座標データロード部（１０３）と、ロードされた座標データを異なる座標系に変換する座標変換部（１０４）と、変換されて得られる変換済み座標データを用いて、ポリゴンが描画の対象となるか否かを判定するポリゴン消去判定部（１０５）と、有効と判定されたポリゴンを構成する頂点は有効であると判定する頂点消去判定部（１０６）と、有効と判定された頂点のみに対応する形態データをロードする形態データロード部（１０７）と、ロードされた形態データと変換済み座標データとを用いてポリゴンを描画するポリゴン描画処理部（１０８）とを備える。
