Outline of Final Research Achievements

Design softwares used for manufacturing require efficient and realistic CG rendering techniques. Although several methods have been proposed for this purpose, most of them rely on heuristic assumptions. This incurs users on tedious parameter tunings to obtain rendering results with desired accuracies. This research project aims to develop a rendering method that can estimate the error accurately and control the error, which can eliminate the tedious parameter tunings from the users. Our method only requires two intuitive parameters and can render the results with desired accuracy.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は,許容相対誤差と信頼水準という2つのパラメータを与えたら,真値との誤差を確率的に推定し,許容相対誤差以内となるようにクラスタを自動的に決定する点にある.モンテカルロ法と異なり,誤差を定量的に推定し制御することができるため,ユーザの負担が大幅に軽減され,デザイン編集や映像制作への福音となる.
