All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

A method for displaying a BIM model component, as shown in FIG. 2, comprises:
And 203, determining to render and display the target component according to the two-dimensional expression data and/or the three-dimensional expression data according to the target display mode.
In the embodiment, expression data of a target component in a BIM (building information modeling) model is acquired, the expression data comprises two-dimensional expression data and three-dimensional expression data, the expression data of the target component is separated, the two-dimensional expression data and/or the three-dimensional expression data are rendered and displayed according to the expression modes included by the target display mode, conversion between the two-dimensional expression data and the three-dimensional expression data is not needed when different expression modes are switched, different expression data can be selected for rendering according to the target display mode, the problem that the conversion process between different expression modes of the target component is complicated is solved, the rendering difficulty is reduced, and the data processing speed is increased.
In one embodiment, obtaining expression data of a target member in a BIM model comprises: acquiring identification information of a target component; acquiring expression data corresponding to the identification information according to the identification information and a preset mapping relation; the mapping relation is the mapping relation between the identification information and the expression data.
The expression data comprises two-dimensional expression data and three-dimensional expression data; the mapping relation comprises a mapping relation of the identification information and the two-dimensional expression data in a two-dimensional expression mode, and a mapping relation of the identification information and the three-dimensional expression data in a three-dimensional expression mode; the two-dimensional representation data comprises description data of a two-dimensional abstract figure of the target member; the three-dimensional representation data includes description data of a three-dimensional figure of the target member. The identification information of the target component is obtained, the description data of the two-dimensional abstract graph and the description data of the three-dimensional graph of the target component corresponding to the identification information can be obtained according to the identification information, and the rendering display is carried out according to the description data of the two-dimensional abstract graph and/or the description data of the three-dimensional graph determined according to the target display mode.
The target member may be a family member, a nested family member in the family member, or any component in the family member or the nested family member. The two-dimensional data is represented by a symbolic line, the symbolic line is only displayed in a two-dimensional view, the three-dimensional data is an entity geometric figure and is displayed in the three-dimensional view by default, whether the figure is displayed in the two-dimensional view can be set, and the two-dimensional view comprises a two-dimensional plane view and a two-dimensional vertical view.
The two-dimensional expression is used as an abstract symbol of the component, so that the component can be accurately represented, and the drawing habit of a designer is met. The two-dimensional representation can be displayed on both a plane and a facade.
The BIM model is a three-dimensional information model, all components in the model are real mapping of real objects, and when a design result needs to provide the three-dimensional model, the BIM model is presented. When a two-dimensional drawing is required for a design result, a three-dimensional component needs to be abstracted into a specific symbol on two dimensions for expression, so that the drawing specification and the habit in the traditional design are met.
The target member is exemplified as a door in a building, as shown in fig. 3, which is a three-dimensional representation, a two-dimensional planar representation, and a two-dimensional facade representation of the door, respectively. It can be seen that the representation of the door in two dimensions, whether it is a two-dimensional planar representation or a two-dimensional facade representation, is not a true mapping of the door, but these two-dimensional abstract symbols are common names agreed in the industry and do not affect the reading of other people. Such abstract expressions are also numerous in the building, construction, water heating and electricity professions. In the mapping relation, two-dimensional expression data and three-dimensional expression data are respectively stored, the corresponding two-dimensional expression data and three-dimensional expression data are called according to identification information of a target component, the two-dimensional expression data are rendered and displayed when the two-dimensional expression data need to be displayed, the three-dimensional expression data are rendered and displayed when the three-dimensional expression data need to be displayed, decoupling of the two-dimensional expression data and the three-dimensional expression data is achieved, the problem that the expression mode of each vertex needs to be modified when conversion is carried out between the two-dimensional expression and the three-dimensional expression is solved, the conversion difficulty is greatly simplified, and the efficiency of switching the expression modes is improved.
In order to improve the efficiency of two-dimensional expression and three-dimensional expression conversion, two-dimensional expression data and three-dimensional expression data can be rendered at the same time, expression data needing to be displayed is rendered and displayed, and expression data which do not need to be displayed temporarily can be rendered for later use in a background.

The first presentation mode may include presenting two-dimensional expression data.
When two-dimensional expression data need to be displayed, the main thread performs rendering display of the two-dimensional expression data, and simultaneously performs synchronous rendering of the three-dimensional expression data in the background thread, so that the 2D plane can be drawn in real time through the main thread on the main interface, the 3D model is rendered in the background through the background process in an off-screen rendering mode, the main thread is prevented from being jammed, and the operation smoothness is improved. And in the mapping relation, the two-dimensional data and the three-dimensional data are stored independently, so that no coupling relation exists, and the two-dimensional data and the three-dimensional data can be rendered independently during rendering, for example, during two-dimensional expression, the data of three-dimensional expression does not need to be considered, the number of surface patches and the number of vertex points are reduced, the rendering efficiency is higher, the required expression mode is rendered in a main thread, and the rendering efficiency of a computer can be balanced sufficiently. When the three-dimensional expression data is required to be switched to be displayed, the rendered three-dimensional expression data can be directly displayed, the processing speed in the switching of the expression modes is increased, and the user experience is improved.
In one embodiment, the target display mode is a second display mode; rendering and displaying the target component according to the two-dimensional expression data and/or the three-dimensional expression data, wherein the rendering and displaying comprises the following steps: in the main thread, performing three-dimensional rendering display on the target component according to the three-dimensional expression data; and performing two-dimensional rendering display on the target component according to the two-dimensional expression data in a background thread. The second presentation mode may include presenting three-dimensional representation data.
When three-dimensional expression data need to be displayed, the main thread performs rendering display of the three-dimensional expression data, and simultaneously performs synchronous rendering of the two-dimensional expression data in the background thread, so that 3D real-time drawing can be performed on a main interface through the main thread, and a 2D model is rendered in the background through the background process in an off-screen rendering mode, so that the main thread is prevented from being jammed, and the operation smoothness is improved. In the mapping relation, the two-dimensional data and the three-dimensional data are stored independently, the two-dimensional data and the three-dimensional data are expressed respectively, no coupling relation exists, rendering can be carried out independently during rendering, a required expression mode is rendered in a main thread, and the rendering efficiency of a computer can be balanced sufficiently. When the two-dimensional expression data needs to be switched to be displayed, the rendered two-dimensional expression data can be directly displayed, the processing speed in the process of switching expression modes is increased, and the user experience is improved.
In one embodiment, a method comprises: and rendering the target component rendered by the main thread in the first area, and rendering the target component rendered by the background thread in the second area. Since the building block includes the two-dimensional expression data and the three-dimensional expression data, the developer can edit the building block in the two-dimensional state or the three-dimensional state. When a developer edits the component in a two-dimensional editing mode, displaying a two-dimensional model of the component in an editing area, and displaying a corresponding three-dimensional model in a preview area; and when the developer switches to the three-dimensional editing mode, displaying the three-dimensional model of the component in the editing area, and displaying the corresponding two-dimensional model in the preview area.
In this embodiment, the two-dimensional expression data and the three-dimensional expression data can be simultaneously displayed on the rendering display interface, the first area and the second area are different areas in the rendering display interface, the first area can be an editing area, the second area can be a preview area, and the two-dimensional expression data and the three-dimensional expression data can be respectively displayed in the editing area and the preview area. And when switching, the rendering display contents of the editing area and the preview area are switched. In one embodiment, the method further comprises: acquiring modification parameters of a target component; and modifying the two-dimensional expression data and the three-dimensional expression data simultaneously according to the modification parameters.
In this embodiment, if the two-dimensional expression data and the three-dimensional expression data need to be modified, the parameters may be edited at the front end to obtain modified parameters, and the two-dimensional expression data and the three-dimensional expression data at the rear end are modified according to the modified parameters. The method can be applied not only before the target component is determined to be rendered and displayed according to the two-dimensional expression data and/or the three-dimensional expression data, but also after the target component is determined to be rendered and displayed according to the two-dimensional expression data and/or the three-dimensional expression data. Specifically, as shown in fig. 4, the method includes: step 401, front end editing; step 402, changing parameters; step 403, modifying data; step 404, modeling data; step 405, re-render. For example, the front end is performing two-dimensional expression, after the parameters of the front end are changed, the two-dimensional expression data of the back end and the three-dimensional expression data corresponding to the parameters are modified according to the modified parameters, data modeling is driven through the expression data, and two-dimensional rendering is performed again at the front end, wherein the expression data comprises the two-dimensional expression data and the three-dimensional expression data.
In one embodiment, the method further comprises: acquiring original data of a BIM (building information modeling) model, wherein the original data comprises family data and nested family data in the family data; the family data and the nested family data are separated, and expression data of the target member included in the separated family data and nested family data are extracted, respectively.
When the method is used for a terminal side, for example, the method is applied to a browser side for online rendering, if the original data of the BIM model is directly rendered, multiple references exist among members in the original data, and redundant information is more, for example, a door exists on one wall, in the original data of the BIM model, the data of the door can store the information of the wall, and the data of the wall can also store the information of the door, so that the general data volume of the original data is larger, the data transmission time cost can be increased, and meanwhile, the transmission speed is also required to be very high. In this embodiment, the original data is processed in advance, the target component to be rendered and the information included in the target component and required for rendering in the original data are extracted, and a component (component) is separately formed, so that after the component is added, the data user only pays attention to the data that the user wants to pay attention to, and the redundant information of multiple references is removed from the data in the component, so that the data is relatively compact. The expansibility of the component is strong, and all the components which need to be added later can be included.
The original data has no component part, and a data user needs to find needed data in all data, so that the data is complex to use. The data format of the embodiment includes a component part, and a data user only needs to search the component for data to render, so that the data can be used more directly. By the method, data needed in front-end rendering is organized in advance, compared with original data of the BIM model, the data volume is greatly reduced, and due to the fact that the data are simplified, the data transmission time is shortened, the front-end data interaction efficiency can be improved, and the rendering efficiency can be further improved.
The nested group data refers to group data nested in the group data, for example, the parking space includes a stretching body, characters, a vehicle pier and the like, the parking space is the group data, and the vehicle pier is the nested group data. In the present embodiment, family data and nested family data in original data are separated, and expression data of a target member contained in the separated family data and nested family data are extracted, respectively. Taking a parking space as an example, separating a stretching body, characters, a pier and the like in original data of the parking space from the parking space, storing the separated stretching body, characters, pier and the like in the parking space into a component, rendering identification information corresponding to a component according to needs when the parking space needs to be rendered, correspondingly searching response data in the component, acquiring corresponding two-dimensional expression data in the component if two-dimensional rendering is required, and acquiring corresponding three-dimensional expression data in the component if three-dimensional rendering is required.
The family data can be classified according to the family type data, the family data with the same family type is stored together, the family data with the same family type shares a set of templates, the family data is distinguished by the ID, the data is further simplified, the size of the data is reduced, and the front end can be conveniently used.
It can be understood that, since the BIM model is composed of a plurality of components, a person skilled in the art can obtain a corresponding method for displaying the BIM model by the method for displaying the BIM model components provided by the present invention. In this way, the developer can switch between two-dimensional or three-dimensional modes at will while viewing or editing the BIM model.
