The BIM is a virtual building created in a computer by means of digitization, which contains geometric information describing the visual appearance of the building and non-geometric information related to the building components, such as building material information, procurement information, construction cost information, etc. That is, the BIM model is effectively a database that records all data information for the building. The core of the BIM model application lies in that the data can be utilized to run through the whole life cycle of the building, and play an important role in the construction and later operation management of the building.
The base members in the BIM model generally include foundations, columns, beams, plates, walls, etc., and also include various professional models such as heating and ventilating models, electromechanical models, soft-mounted models, etc. The generation of the BIM model typically uses client design software (e.g., revit) that constructs the BIM model to be viewed only in its own software. If the BIM model is required to be viewed on a mobile phone or a webpage, the BIM model is required to be subjected to lightweight processing and then rendered through a web rendering engine. Although the online visualization provides convenience for viewing the model, the BIM data is often very huge, so that the traditional online visualization has the problems of slow data loading, poor interactivity, complex operation, low stability, poor visualization effect and the like.

Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Examples
The method for browsing a BIM model quickly in this embodiment is mainly implemented by the following steps, which are detailed in the flowchart shown in fig. 1.
S100, constructing a spatial index and quickly reducing the view range by selecting the spatial index.
In the traditional practical related application of the BIM model, many applications only need to be able to view the shape and structure of the building element at a certain viewpoint and then view non-geometric data associated with the building element, such as building material information, procurement information, construction cost information, etc., but the internal structure of the BIM model is often complex and it is complex to quickly locate the viewpoint and select the building element. Therefore, the present invention firstly needs to select the spatial index to quickly narrow the view range, so as to jump to the ideal view as soon as possible.
The spatial index in this step refers to the division of the spatial range of the BIM model according to the actual building function space, and the viewpoint of the space can be quickly positioned in the BIM model through the spatial index.
Where the space in the BIM model can be described as the elevation, the coordinates of the vertices of the polygon on the bottom surface and the height within the BIM model, the virtual space generated is in fact a range made up of a series of three-dimensional points. Through the range of the space, the building components in the space can be accurately inquired.
The spatial index includes a plurality of communication relationships of independent spaces in addition to the range of each space. In an actual scene, each functional space has a certain connection relationship, for example, whether two spaces are adjacent or not, whether the spaces are reachable or not, and the like, so that the relationship between the spaces can be represented by a communication relationship diagram of a plurality of spaces. In this embodiment, the space may be divided into a field space, a building space, a floor space, a room space, and a sub-function space, and each type of space may be configured with a communication diagram separately, such as a communication diagram between floors and a communication diagram between rooms. Through the communication relation of each type of multi-level space, the next space viewpoint which is possibly jumped by the current space viewpoint can be quickly searched, the viewpoint can be quickly switched according to the actual user requirement, and good interactivity can be realized when roaming checking is required in the BIM.
And S200, reconstructing a data index of the BIM corresponding to each view point by using the rendering result of each view point.
When a traditional BIM is previewed directly on line, because a rendering engine of the traditional BIM needs to calculate the triangular surface required to be displayed in each viewing cone, and then each frame of picture is generated and displayed by utilizing a rendering technology, the calculation of the method is very slow under the condition that the number of the triangular surfaces of the BIM is large, and the method is limited by the hardware condition of terminal equipment, and the poor hardware display effect is poor.
Therefore, in order to display the content of the BIM model at a certain view point, the present invention uses a rendering-in-advance mode to store the rendering result of each view point in a picture or panorama mode, and based on this, the data index of the corresponding BIM is reconstructed. The method can meet the requirements of checking each component of the BIM and browsing BIM data, greatly improves the loading speed when online previewing is carried out, and can obtain better rendering effect when offline rendering is carried out.
As shown in the flowchart of fig. 2, the reconstructing the data index of the BIM corresponding to each view by using the rendering result of each view includes the following specific steps:
s201, calculating the preset viewpoint position and direction of the BIM model, and generating the position and range of each viewpoint.
According to the invention, before off-line rendering, a viewpoint and a rendering range must be calculated firstly, and in consideration of friendly interactivity and maximized convenient query components, different viewpoints are generated for each type of space according to a plurality of levels of spaces, for example, in a building space, viewpoints parallel to the direction and a 45-degree direction are generated respectively by taking a plurality of plane directions of a building polygonal cube as references, and the distance from the viewpoint to the building space is limited by looking up all components in the space, so that the optimal distance is calculated, and a plurality of preset viewpoints of the building space are generated.
For another example, for a room space, a viewpoint in the room space targets a BIM model component that can view the range as much as possible, a point is preset in the center of the room space, and a point is preset in each corner of a polygon cube in the room space. To summarize, it is possible to view more BIM model components in each space as the viewpoint preset for the destination component.
S202, rendering the picture or the panoramic picture of each viewpoint in an off-line mode according to the position and the range of the generated viewpoint, and generating the rendered panoramic pictures and pictures related to all the viewpoints.
After step S201 is completed, the picture needs to be rendered according to the view information, that is, the picture or panorama of each view is rendered by an offline rendering method. The offline rendering uses professional rendering tools, such as rendering engines of 3dmax, ue4, unity and the like, the BIM model is firstly loaded into the rendering engine, then the camera is adjusted to the position of a viewpoint to be rendered, and finally the rendering engine is started to generate a rendering graph. In particular, it is necessary for generating the panorama to change the visual rotation range of the viewpoint to 360 degrees to generate the panorama. In this way, all view-dependent panoramas and pictures are generated.
And S203, calculating the corresponding picture range of the model component in the view point.
Since the pictures or panoramas of the respective viewpoints in the BIM model generated by offline rendering can only be used to view the appearance of the BIM model, and there is no interaction or operation, it is also necessary to generate the corresponding range of the component on each picture. In contrast to pictures, the range of a component can be represented by a planar polygon, specifically by a series of two-dimensional pixel coordinates and a connection relationship between points.
In the off-line rendering process, when each image is rendered at each viewpoint, the coordinates of three-dimensional points of the edges of the components in the viewpoint range corresponding to the coordinates of two-dimensional points on the image are calculated according to a coordinate system loaded to an engine by a BIM (building information modeling), and then the vertices of a polygon are generated according to a group of two-dimensional points on the image and the smoothness of continuous pixels, so that the data volume is reduced.
For each BIM component in the visual range in Zhang Xuanran map of the viewpoint, its corresponding polygon range point should be generated, and for each rendering map, the range point coordinates of its corresponding BIM component are stored separately. For components that are within the range of visible points and within the current corresponding spatial range, range point coordinates should also be generated for components that are occluded by other components. Meanwhile, all generated coordinates in the step need to be stored by using a data file.
And S204, storing the non-geometric data of the model component.
The invention should save non-geometric data in the BIM model of the BIM component besides the range of rendering the image, and the data is very useful in some application scenes, such as building tracing, looking up manufacturers and the like. For each rendering, individual files are used to store non-geometric information for each component in the rendering, which can be queried by the ID of the component.
And S205, calculating the picture range corresponding to the space in the view point.
In this step, for each rendering, the range of other spaces existing therein needs to be saved, for example, a rendering under a floor space may include multiple room spaces, for a subspace, a separate file should be used to save the range of the subspace, and the generation method is similar to the component range, and generates a polygon of its boundary range.
Since the image-based BIM data has been completely constructed, one BIM model should generate a rendered image, component range information, non-geometric data information, and subspace range information for each viewpoint in a scene.
S300, image information is selected according to the data type.
The step is different from the step of selecting component browsing data through mapped three-dimensional points in a general BIM model, and the step is selected on the rendered image of each viewpoint according to the type of data needing to be browsed.
For viewing building components of the BIM model, the component range polygons are directly drawn on the rendering map, and the specific components are directly positioned through user selection. For the component occluded in the space, after the component is selected by the component name in the drop-down list and located, the corresponding non-geometric information can be inquired through the ID of the component.
For viewing the spatial sub-region of the BIM model, the polygon range corresponding to the space is directly drawn on the rendering map, and the information of the space and the components of the space can be viewed by selecting the range. And selecting different polygon ranges according to different data types, and querying corresponding information according to the component ID or the space ID to query BIM related data.
S400, switching of the BIM scene is completed according to the spatial index.
In order to achieve good interactivity and fluency, the invention adopts the spatial index as the basis to complete the switching of the BIM scene, and the specific content is as follows: initially, a user selects a starting viewpoint as required, a scene is switched to an image or a panoramic image corresponding to the viewpoint, and the user selects components, views spatial information, views component information and the like in the scene as required.
When loading a scene of a viewpoint, a buffer area is required to be set, and the buffer area contains images of an adjacent communicated space of a space where the current viewpoint is located. When the user views the next space, the image is directly taken out from the buffer area, and the loading of the image is completed. The scene switching is carried out by utilizing the spatial index, so that the interactivity is improved by giving a fixed viewpoint to a user, and the fluency is improved by caching images of adjacent spaces in the spatial index.
As described above, the present invention can be preferably realized.
