Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating presentations of views of building entities according to an interaction graph. One of the methods includes processing building information model data to identify a plurality of building entities, wherein each building entity represents a respective feature of a building modeled by the data. Relationships between different respective pairs of the building entities are determined. The relationships are traversed according to simulated user interactions with respective presentations of a plurality of the building entities. At each subsequent building entity encountered by traversing the plurality of relationships, a respective presentation of a view of the building entity is generated, wherein the respective presentation includes one or more selectable references to one or more other views of one or more other building entities corresponding to one of the determined relationships between the building entities.

Abstract: A photo localization application is configured to determine the location that an image depicts relative to a 3D representation of a structure. The 3D representation may be a 3D model, color range scan, or gray scale range scan of the structure. The image depicts a particular section of the structure. The photo localization application extracts and stores features from the 3D representation in a database. The photo localization application then extracts features from the image and compares those features against the database to identify matching features. The matching features form a location fingerprint, from which the photo localization application determines the location that the image depicts, relative to the 3D representation. The location allows the user to better understand and communicate information captured by the image.
Abstract translation: 配置照片本地化应用以确定图像相对于结构的3D表示描绘的位置。 3D表示可以是结构的3D模型，颜色范围扫描或灰度范围扫描。 该图像描绘了结构的特定部分。 照片本地化应用程序从数据库中的3D表示中提取和存储功能。 然后，照片本地化应用程序从图像中提取特征，并将这些特征与数据库进行比较，以识别匹配的特征。 匹配特征形成位置指纹，相对于3D表示，照片定位应用从该位置指纹确定图像描绘的位置。 该位置允许用户更好地理解和传达由图像捕获的信息。
