Title
(JA) 三次元物体の表現の直列化
Abstract
(JA)

一例において、本方法は、一層ずつの製造プロセスで製造される物体の少なくとも一部を表すデータをプロセッサで受信することを含む。データから、物体の少なくとも一部の直列化八分木表現を生成することができる。直列化八分木表現において、ノードは次のように順序付けられる。すなわち、(i)物体生成の意図された順序において先に生成される物体の層を含む体積を表すノードが、その後に生成される物体の層から構成された体積を表すノードに先行し;(ii)物体の所与の層を含む体積を表すノードが、八分木表現内のノードのレベルに基づいて順序付けられ、親ノードが、子孫ノードよりも前に現れ;(iii)物体の所与の層を含む体積を表すノードであって八分木表現内で同じレベルにあるものが、位置符号化パターンに従って順序付けられる。
