Abstract: 詳細度レベルによる物体表面の質感変化を分析し,人間の視覚特性を考慮した物体表面の凹凸形状に対する視認性のよいリアルタイム表現を行った.その結果,物体表面の凹凸付けに対する様々な手法を,物体表面の詳細度に応じて切り替えて適用することで,1~2割程度の速度の向上を確認した.また,物体表面の陰影付けに際し凹み部分の遮蔽による陰影付けを行うことで,凹凸状態の視認性が良好になる手法を提案した. : We have analyzed change in visual impression depending on Level-of-detail(LoD) of an object’s surface, and developed a real-time representation method for material data to increase noticeability of surface bumpiness considering human visual features. As a result, the method adapts LoD to object surface details and changes rendering technique corresponding LoD, and improves performance around 10-20%. We also added realism to surface dents or grooves without deforming surface geometry, and achieved better perception of the three dimensional surface shape.
