Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the disclosed embodiments. However, it will be apparent to one skilled in the art that the present disclosure may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present disclosure with unnecessary detail.

Further, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to".

In the description of the present disclosure, it is to be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Further, in the description of the present disclosure, "a plurality" means two or more unless otherwise specified.

In the field of building construction, a building plan is a drawing composed of a horizontal projection method and corresponding legends according to the building conditions of a newly-built building or the functional layout of the wall, the door and window, the stairs, the ground and the interior of the building. The building plan is used as an important component in building design and construction drawings, reflects the conditions of plane shape, size, internal layout, specific positions and occupied areas of the ground, doors and windows and the like of a building, is an important basis for construction and construction site arrangement of a newly built building, and is also a basis for designing and planning professional engineering plans of water supply and drainage, strong and weak electricity, heating and ventilation equipment and the like and drawing a comprehensive pipeline drawing. The building plan can be divided into a building construction drawing, a structure construction drawing and an equipment construction drawing. Floor plans for building construction typically include a floor plan, a standard floor plan, a roof plan, and a roof plan.

During the construction of a building, each process may involve the modification of a drawing, which usually needs an engineering technician to manually perform on professional drawing software (e.g., AutoCAD, SketchUp, 3D Studio Max), and thus, a lot of labor and time costs are consumed; furthermore, because the drawing is drawn manually, the drawing speed of the drawing is slow, and the quality of the drawing is difficult to ensure. In addition, when the user puts forward personalized requirements, because the areas where the user is located are different and the AutoCAD software based on the C/S structure does not have cross-platform capability, the cooperation and communication between the user and engineering technicians are difficult; furthermore, because the modification of the drawing is completed on line based on the paper drawing, the problems of loss, confusion, damage and the like of the modified drawing are easy to occur.

Therefore, the conventional drawing modification method mainly depends on manual operation of engineering technicians, and although some products capable of directly analyzing the CAD drawing through a graphic engine exist in the market, the products cannot analyze the three-dimensional model and cannot meet the requirement of online editing of the engineering technicians. Therefore, it is necessary to provide a scheme capable of editing a two-dimensional drawing or a three-dimensional model on line based on a graphic engine to optimize an editing process, improve editing efficiency, reduce error rate, and save a lot of manpower and time costs.

In some embodiments, obtaining a building plan parsed from a building information model and displaying the building plan through a web page includes: obtaining model data of a building information model, and converting the model data into data which can be identified by a lightweight engine by using a conversion plug-in, wherein the conversion plug-in is a Revit plug-in; storing data recognizable by the lightweight engine into JSON format data, wherein the JSON format data comprises attribute data and entity data, the attribute data comprises floor identification of a floor, the entity data comprises entity attribute data and entity geometric data of each entity in a plurality of entities in the floor, and the entity attribute data comprises type data of each entity; and analyzing the JSON format data by using a lightweight engine to obtain adjusted model data, and displaying a building plan generated based on the adjusted model data through a webpage.

Specifically, the server extracts model data in the building information model, converts the model data into data recognizable by a lightweight engine using a conversion plug-in such as a Revit plug-in, and stores the data as JSON-format data including attribute data including floor identification of a floor and entity data including entity attribute data and entity geometric data of each of a plurality of entities in the floor, the entity attribute data including type data of each entity; further, the server analyzes the JSON format data by using the lightweight engine to obtain adjusted model data, and displays a building plan generated based on the adjusted model data through a webpage.

Here, Plug-in (Plug-in) is a program written in an application program interface following a certain specification, and can only run under a system platform (possibly supporting multiple platforms simultaneously) specified by the program, and cannot run separately from a specified platform. The conversion plug-in may be a Revit plug-in. The Revit plug-in is a plug-in for secondary development. Here, the secondary development means that customized modification is performed on existing software to extend functions, that is, to achieve desired functions; secondary development does not typically change the kernel of the original system.

And the lightweight engine is used for carrying out lightweight conversion on the BIM model, and loading and using the lightweight model. The light weight conversion is to convert the BIM into primitive data and model structured data through a light weight engine, wherein the primitive data is stored in the form of an original file; the model structured data is saved in a corresponding relational database in the form of data records so as to facilitate the retrieval and utilization of the data at a later time. The lightweight model is loaded and used by displaying the lightweight BIM in a webpage by using WebGL (Web Graphics library) technology, and the lightweight BIM comprises a BIM control function, a model component attribute customization function, a BIM model-based labeling and displaying function and the like.

WebGL is a three-dimensional (3D) drawing protocol, the drawing technical standard allows JavaScript and OpenGL ES 2.0 to be combined together, and by adding one JavaScript binding of OpenGL ES 2.0, WebGL can provide hardware 3D accelerated rendering for HTML5 Canvas, so that a Web developer can not only more smoothly display 3D scenes and models in a browser by means of a system display card, but also can create complex navigation and data visualization. Therefore, the WebGL technical standard avoids the trouble of developing a webpage-dedicated rendering plug-in, can be used for creating a website page with a complex 3D structure, and can even be used for designing a 3D webpage game and the like.

Json (javascript Object notification) is a lightweight data interchange format that stores and represents data in a text format that is completely independent of programming languages, based on a subset of ECMAScript. The JSON has a simple and clear hierarchical structure, is easy for a user to read and write, and is also easy for machine analysis and generation, so that the network transmission efficiency is effectively improved. Preferably, in the embodiment of the present disclosure, the data recognizable by the lightweight engine is GeoJSON format data. Here, GeoJSON is a format for encoding various geographic data structures, a geospatial information data exchange format based on Javascript object notation. The GeoJSON object may represent a geometry, a feature, or a set of features. GeoJSON supports the component types described above: point, line, face, multipoint, multiline, multifaceted and geometric collections.

The JSON format data may include attribute data and entity data. The attribute data may include, but is not limited to, a floor identification of a floor, a floor name, a floor height, etc., and the entity data may include entity attribute data and entity geometry data for each of a plurality of entities in the floor, where an entity refers to various elements in a building plan, including resources and components.

The operation performed by the access node depends on the specific application problem, and the specific access operation may be to check the value of the node, update the value of the node, and the like. Different traversal methods have different access node orders. In the embodiment of the present disclosure, the traversal refers to performing a traversal operation on all entities under the same floor to acquire type data of each entity, so that separation of resource data and component data can be performed based on the type data of each entity.

Here, the correspondence relationship refers to the amount of resources occupied by the object. For example, the corresponding relationship may be that one object occupies one resource, one object occupies two resources, one object occupies three resources, one object occupies five resources, and the like. Further, the corresponding relationship may be a relationship preset by the user according to experience data, or may be a relationship obtained by adjusting the set relationship according to actual needs by the user, which is not limited in the embodiment of the present disclosure. Preferably, in the embodiment of the present disclosure, the object is a shop area composed of shops (resources).

For example, suppose that a third building in mall A has multiple shops, and the shops are all vacant, as shown in FIG. 2 a. If "ABC child" wants to rent two shops of "A-3F-04" and "A-3F-05 b", and "TD calligraphy education" wants to rent a shop of "A-3F-05 a", it indicates that "ABC child" occupies a number of shops of 2 and "TD calligraphy education" occupies a number of 1, and thus, the two shops (resources) of "A-3F-04" and "A-3F-05 b" are merged and displayed as "ABC child" (object), and "A-3F-05 a" is displayed as "TD calligraphy education", as shown in FIG. 2 b.

Specifically, the server traverses the plurality of resource objects and the plurality of component identifiers one by one to determine whether a resource identifier or a component identifier matching the target area identifier exists in the plurality of resource objects and the plurality of component identifiers. Optionally, in the case that it is determined that there is a resource identifier or a component identifier matching the target area identifier in the plurality of resource identifiers and the plurality of component identifiers, the server performs color filling and/or diagonal processing on the target area in the building plan.

In some embodiments, in a case that it is determined that there is a resource identifier or a component identifier matching the target area identifier in the plurality of resource identifiers and the plurality of component identifiers, performing an online editing operation on the resource or the component corresponding to the resource identifier based on the online editing instruction includes: and under the condition that the resource identifier or the component identifier matched with the target area identifier exists in the plurality of resource identifiers and the plurality of component identifiers, carrying out online editing operation on the resource corresponding to the resource identifier or the component corresponding to the component identifier by calling the corresponding application program interface based on the online editing instruction, and obtaining the edited building plan.

Specifically, under the condition that the resource identifier or the component identifier matched with the target area identifier exists in the plurality of resource identifiers and the plurality of component identifiers, the server calls the corresponding application program interface to perform online editing operation on the resource corresponding to the resource identifier or the component corresponding to the component identifier based on the online editing instruction, and the edited building plan is obtained.

Here, an Application Programming Interface (API), also called API, is a convention for linking different components of a software system. The API is actually a function set, and from the perspective of a user, the API appears as a series of API functions which can be used by the user to develop network application programs; from the network perspective, the API provides a set of methods for the user, the user can use the set of methods to send service requests, information and data to the application layer, and the layers in the network respond in sequence to finally complete the network data transmission. In the embodiment of the present disclosure, the editing module provides a rich interactive editing API based on an autonomously developed geometry Math (Math) library and a two-dimensional (2D) rendering library, and dispatches edited update data to a two-dimensional or three-dimensional (3D) rendering engine by using an event dispatch (EventDispatch) mechanism to perform visual rendering on an edited building plan, as shown in fig. 2 c.

Further, the full-scale professional adsorption operation can be achieved through the quadtree scene division and the application of the Web Worker, all the editing operations are based on the full-scale adsorption, and the scale driving is used in an auxiliary mode, so that the accuracy of the editing operations is guaranteed. The basic idea of full-scale adsorption is to divide the space into tree structures with different hierarchical structures, divide the space of a known range into four equal subspaces, and stop the segmentation until the tree hierarchy reaches a certain depth or the number of objects in the subspaces is less than a certain value. Arcs which do not need to participate in adsorption calculation can be removed through full adsorption, and the main thread rendering cannot be blocked by adopting Web Worker to calculate adsorption.

Since all application scenarios cannot be satisfied even if the full adsorption is satisfied, for example, a user wants to adsorb a mouse when moving to a vertical or horizontal direction of a node, the embodiments of the present disclosure provide an auxiliary line and an extension line. The auxiliary lines are divided into two modes of line segment auxiliary lines and ray auxiliary lines, the auxiliary lines and end points of the auxiliary lines have adsorption capacity, and the extension lines enable the vertical and horizontal directions of the nodes to have adsorption capacity.

The scale driving means that another point is accurately obtained through scale driving relative to one datum point, and the unit is accurate to two digits after a decimal point. The scale driving may include a quadrature driving mode, a line segment mode, and an axis component driving mode.

The partition of the closed polygon may be implemented by a Depth-First Search (DFS) algorithm, that is, the vertices and edges of the closed polygon are combined into a graph, and the Depth Search obtains all the minimum closed polygons (which do not include more than one sub-polygon).

Math is a built-in mathematic function library provided by Python, does not support complex types and only supports integer and floating point operations. In the disclosed embodiments, the autonomously developed geometric mathematics library provides nearly one hundred mathematical methods to support the implementation of the editing API. The core functions of the edit API may include geometric additions, geometric calculations, and geometric measurements, where the geometric additions may include, but are not limited to, resources and holes (e.g., circles, rectangles, and closed polygons), fire fighting equipment (e.g., fire curtains, fire hydrants), fire doors, walls (e.g., straight walls), aid lines (e.g., rays, conventional aid lines); geometric operations may include, but are not limited to, polygon operations (e.g., boolean operations, division, deletion, rotation, and translation) and line segment operations (e.g., node edits, line segment arc rotations, and rounded corners); geometric measurements may include, but are not limited to, dot pitch, arc pitch, and area, as shown in FIG. 2 d.

Event dispatch is the dispatching of an event to a specified event target and the triggering of the affected event targets in the proper order. By using an event dispatching mechanism, more complex decoupling can be completed, and the coupling degree between codes is reduced.

PixiJS provides seamless Canvas fallback, supporting mainstream browsers, including desktop and mobile. By using PixiJS in combination with various graphics optimization means, full-volume professional rendering can be achieved.

ThreeJS is a 3D rendering engine running in a browser for creating various three-dimensional scenes in a webpage, and is an easy-to-use 3D rendering library formed by packaging and simplifying a WebGL interface. The thread js adopts a physical-Based Rendering (PBR) technology to realize batch merging of different materials on the basis of batch merging of the same material, so that the communication cost is reduced, and smooth interactive experience and Rendering effect are provided.

Specifically, the pre-configured visualization list stores the type of the architectural plan that the user desires to obtain, for example, a two-dimensional visualization image or a three-dimensional visualization image; after the edited building plan is obtained, the server drives a corresponding PixiJS or ThreeJS engine to perform visual rendering on the edited building plan based on the type of the building plan to obtain a two-dimensional visual image or a three-dimensional visual image; further, the server displays the two-dimensional visualization image or the three-dimensional visualization image using a web page. Here, the visualization list may be a list pre-configured by the user according to empirical data, or may be a list obtained by adjusting the configured list according to actual needs by the user, which is not limited in the embodiment of the present disclosure.

For example, taking an escalator in a shopping mall plan as an example, if a two-dimensional visual image of the escalator is desired to be displayed, the two-dimensional visual rendering may be performed on the shopping mall plan through the pixijjs engine to obtain a two-dimensional visual effect, as shown by a circular area in fig. 2 e; if a three-dimensional visual image of the escalator is desired to be displayed, a three-dimensional visual rendering can be performed on the shopping mall plan through the ThreeJS engine, so that a three-dimensional visual effect is obtained, as shown by a square area in fig. 2 f.

{

"data":{

"properties":{

"RevitID":434843,

"FEATURE_NAME":"3F",

"FEATURE_HEIGHT":11400

"features":{

"properties":{

"FEATURE_NAME2":"",

"FEATURE_AREA":-1,

"FEATURE_NAME":"",

"FEATURE_TYPE":"CBD_FLOOR",

"RevitID":2490618

"geometry":{

"coordinates":[

[

122249.98,

-50847.35

[

128004.02,

-50847.35

It should be noted that, only data of one entity is shown here as an example, and in practical applications, data of multiple entities may be included in the GeoJSON format data.

Secondly, traversing a plurality of entities in the GeoJSON format data by using a lightweight engine based on the floor identification of the floor, and separating resource data and member data of the entity data based on the type data of each entity to obtain adjusted model data, wherein the adjusted model data mainly comprises two parts of contents, namely a resource data set and a member data set.
