          <dc:description>歴史的・文化的な建造物などの3次元的な形状を有する文化財を，レーザ計測によって精密保存する機会が増えている．計測で得られるデータは数千万から数億個以上の3次元点群データである．本論文では，このような大規模3次元点群を，できるだけ加工せずにそのまま利用して，計測対象の内部構造をわかりやすく可視化する手法を提案する．具体的には，最近我々が提案した粒子ベース・レンダリングをレーザ計測データに適用する．また，計測された点群から，計測対象の任意平面における断面線を自動生成し，これを平面図，立面図などの断面図として3次元形状と融合して半透明可視化する．</dc:description>
          <dc:description>Recent rapid development of laser scanners has enabled precise measurement of real 3D objects that are important for cultural and historical reasons. The laser-scanned data are a point cloud that often consists of over 107 or 108 3D points. We propose a novel application of the particle-based rendering to such large-scale laser-scanned 3D point data. Based on the rendering method, we execute precise translucent visualization of complex laser-scanned buildings. We also automatically create a cross-section drawing of a building from its laser-scanned 3D points. We make fused translucent visualization of the created 2D drawing with the 3D structure of the building.</dc:description>
