The invention discloses a conversion method and device of a building information model and a building energy consumption simulation model. Qualitative analysis is performed on a quality current situation of a traditional building information model, space information demand of a building energy consumption mode is integrally considered by taking the qualitative analysis as a basis, a space data extraction algorithm which is widely applied to a building information model is designed, and the problem of dependence of a high-quality building information model is solved. Polygon operation of computation geometry is used as a technical support, a thermal transfer surface matching algorithm, a concave polygon surface conversion algorithm and a hotzone defect detection and filling algorithm duringthe space information conversion process are researched, and accurate conversion between the building information model and the building energy consumption simulation model is achieved.

The invention discloses a BIM (Building Information Modeling) directory tree generation method and device, a product and a storage medium. The method comprises the following steps: determining a unique coding structure of a BIM according to an application demand of the BIM; respectively adding coding information and attribute information of corresponding hierarchies to the BIM model according to the unique coding structure by utilizing a BIM model attribute management tool, and adding sequence codes to the same class of objects with the same coding information; obtaining a unique code of the BIM model; lightweight processing is carried out on the BIM model, and geometric information and attribute information of the lightweight BIM model are associated; and importing the lightweight BIM model and the attribute information into a digital platform, identifying a unique code of the lightweight BIM model, analyzing a coding level, a table code, a classification object code level and a sequence code, matching an analysis result with a classification and coding table in the digital platform, and generating a BIM model directory tree according to the coding level and a matching result. According to the method, the corresponding directory tree can be automatically adjusted along with expansion and adjustment of the model.

The invention discloses a man-machine interaction online game operating method, and aims to solve the problem of poor experience feeling caused by adopting a mouse and a keyboard for operating in conventional online game operation. The man-machine interaction online game operating method provided by the invention specifically comprises the following stepsthatstep 1, a server carries out BIM (Building Information Modeling) on a scene selected by a client, loads a model and projects to the scene; and step 2, a user makea named action on site, equipment obtains the action of the user and carriesout judgement, if it is judged thatthe action represents a command in a server, the server carries out a corresponding command, and if it is judged thatthe action represents no meaning in the server,the service does not make a response. According to the method provided by the invention, a three-dimensional scene and a motion sensing technology are combined, an appointed gesture is used for sending a command to a system to accomplish an appionted action, namely the system is controlled, the traditional mouse and a keyboard operating mode is replaced, and advances in science and technology canbe felt intuitively.
