在这项工作中，我们引入了“移动树”结构，用于复杂3D室内场景的高级功能表示。近年来，数字室内场景变得越来越流行，包括详细的几何形状和复杂的功能。这些场景通常由以各种姿势重复出现并相互关联的对象组成。在这项工作中，我们分析了场景中的对象的重现，并自动检测其功能的移动性。“移动性”分析表示对象及其子部分的运动能力（即自由度），其通常与其室内功能相关。我们通过分析对象的空间排列、重复和与其他对象的关系来计算对象的移动性，并将其存储在“移动性树”中。场景中的重复运动被分组为“移动组”，为此我们开发了一组复杂的控制器，以促进语义高级编辑操作。我们展示了我们的流动性分析的应用程序，交互式场景操作和重组，并提出了各种室内场景的结果。
In this work, we introduce the ‘mobility‐tree’ construct for high‐level functional representation of complex 3D indoor scenes. In recent years, digital indoor scenes are becoming increasingly popular, consisting of detailed geometry and complex functionalities. These scenes often consist of objects that reoccur in various poses and interrelate with each other. In this work we analyse the reoccurrence of objects in the scene and automatically detect their functional mobilities. ‘Mobility’ analysis denotes the motion capabilities (i.e. degree of freedom) of an object and its subpart which typically relates to their indoor functionalities. We compute an object's mobility by analysing its spatial arrangement, repetitions and relations with other objects and store it in a ‘mobility‐tree’. Repetitive motions in the scenes are grouped in ‘mobility‐groups’, for which we develop a set of sophisticated controllers facilitating semantical high‐level editing operations. We show applications of our mobility analysis to interactive scene manipulation and reorganization, and present results for a variety of indoor scenes.
