The portable wearable device can be a smart watch, a smart bracelet, a head-mounted device, and the like. The server 104 may be implemented as a stand-alone server or as a server cluster comprised of multiple servers.
In one embodiment, as shown in fig. 2, a data processing method is provided, which is described by taking the application of the method to the server in fig. 1 as an example, and includes the following steps:
step 202, obtaining a Revit family file, and converting the Revit family file into file object model structure data.
The family is a powerful concept in Revit and is also an indispensable function in Revit, and each family file of Revit contains many parameters and information, such as size, shape, type and other parameter variable settings. The Document Object Model (DOM) is a standard programming interface for the W3C organization to process extensible markup language recommendations. The DOM is an Application Programming Interface (API) that is platform and language independent, and can dynamically access programs and scripts to update their content, structure, and style of www documents (HTML and XML documents are defined by the declarative parts). The document may be further processed and the results of the processing may be added to the current page. The DOM consists of three parts, including: the core (core), the HTML interface and the XML interface, the core part is a set of the comparison bottom object of the structured document, and the defined object can express the data in any HTML and XML document completely. The method can convert the Revit family file into the file object model structure data in a Document loading mode.
Specifically, the processor acquires a Revit family file, and then converts the Revit family file into file object model structure data.
And step 204, traversing the structural data of the file object model to obtain the primitives of various types.
Wherein, traversing means that each node in the tree (or graph) is visited once in turn along a certain search route. 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. A primitive is a graphic representation of any one graphic representation composed of a number of different dots, lines, surface patterns, or cycles of the same pattern. These dot, line, and plane patterns are basic graphic elements. The traversing mode mainly comprises the following steps: obtaining a set element traversal List and traversing the List using an iterator, wherein the List represents an ordered set of elements. There are two common implementation data structures for a List: arrays and linked lists. The internal implementation of the different methods is performed for the different List implementation data structures.
Specifically, the processor first acquires an element set in the Collection, and then traverses the elements in the set to obtain the primitives of each type after acquiring the iterator corresponding to the set.
And step 206, analyzing each type of primitive to obtain attribute information of each type of primitive.
The primitive attributes refer to display characteristics of control primitives. The attribute information of the primitive includes one of a point attribute, a line attribute, a fill area attribute, an area, a character, a primitive generation method, and the like, but is not limited thereto. Where dot attributes include color and size, in a raster system, dots of various sizes are displayed with a square array of pixels. Line attributes include color, width, and type. The line width is specified in multiples of the standard single pixel width. Line attributes include solid, dashed and dotted lines and various brush or brush types. The fill area properties include a solid color fill, a fill pattern fill, or an open fill that merely shows the area boundaries. Various pattern fills are described in terms of color arrays, mapped to the interior of the region. The characters include color, size, spacing, and orientation.
Specifically, the processor analyzes each type of primitive to obtain attribute information of each type of primitive.
And step 208, storing each type of diagram element and the attribute information in an extensible markup language file corresponding to the Revit family file.
The extensible markup language refers to a subset of standard universal markup languages, and is abbreviated as XML. Is a markup language for marking electronic documents to be structured.
Specifically, the processor acquires each type of diagram element and attribute information, and stores each type of diagram element and attribute information in an extensible markup language file corresponding to the Revit family file.
In the data processing method, a Revit family file is obtained and converted into file object model structure data; traversing the structural data of the file object model to obtain the primitives of each type; analyzing each type of primitive to obtain attribute information of each type of primitive; and storing each type of diagram element and attribute information in an extensible markup language file corresponding to the Revit family file, wherein the extensible markup language file can be read to realize parametric modeling, so that the Revit file information can be acquired.
In one embodiment, converting a Revit family file into file object model structure data includes: and loading the Revit family file in a Document loading mode to obtain the file object model structure data.
There are many different types of nodes in the DOM, similar to atoms containing sub-atom particles, and many types of DOM nodes containing other types of nodes. Which comprises the following steps: element nodes, text nodes, and attribute nodes. An element node refers to an atom in the DOM. The DOM access element node includes: obtaining through a top-level document node, obtaining through a father node, obtaining through a neighbor node, and obtaining through a child node. A text node is one of the element node types. For example, in our home page, the '< p >' element contains text, sharee: 'Xiaoming'. A minutia is a text node that is always contained inside an element node. The attribute nodes are used to make more detailed descriptions of the elements.
Specifically, the processor analyzes an HTML file in a Revit family file, loads an external script and a style, analyzes and executes the script in the file, completely constructs an HTML DOM, loads a picture and external content, and loads a webpage to obtain file object model structure data.
In this embodiment, the review family file is loaded in a Document loading manner, so as to obtain an object model structure.
In one embodiment, analyzing each type of primitive to obtain attribute information of each type of primitive includes: analyzing the Revit file to obtain a primitive operation function; and analyzing each type of primitive according to the primitive operation function to obtain the attribute information of each type of primitive.
Wherein the primitive operation function is a function for primitive drawing. The primitive is described using some fixed point sets with order. In the use of primitive manipulation functions, mostly a pair of functions glBegain () and glEnd () are used, and the argument passed to the glBegain () function uniquely determines what kind of geometric primitive is to be drawn, and at the same time, the definition of the geometric primitive is given in the function pair, and the function glEnd () marks the end of the vertex list.
Specifically, the processor analyzes the Revit file to obtain a primitive operation function, and then analyzes each type of primitive according to the obtained primitive operation function to obtain attribute information of each type of primitive.
In this embodiment, the attribute information of each type of primitive is obtained by obtaining the primitive operation function.
In one embodiment, the data processing method further includes:
step 302, the processor reads the extensible markup language file corresponding to the Revit family file, and then obtains attribute information of the primitives in the extensible markup language file.
Specifically, the processor reads an XML file in the Revit family file first, and obtains primitive attribute information in the XML file.
And 304, acquiring a generating mode of the primitive from the attribute information of the primitive, and determining the type of the parameter model according to the generating mode.
The primitive generation methods include stretching (Extrusion), merging (Blend), rotation (Revolume), lofting (Sweep), and lofting merging (SweptBlend). Stretching refers to stretching the lines in the graphical elements proportionally. Blending refers to blending multiple figures together, such as blending two circles. Rotation is the rotation of one figure around a fixed point by a certain angle to obtain the change of another figure. Lofting is the formation of complex three-dimensional objects using a two-dimensional volumetric object as a cross-section along a path. Lofting fusion is that a lofting path needs to be given by a reference line, then two contours of lofting fusion are drawn at two ends of the reference line, and finally the reference line and the two contours at the two ends are simultaneously selected to create a shape.
Specifically, the processor acquires a primitive generation mode from the attribute information of the primitive, and determines the type of the parameter model according to the primitive generation mode.
And step 306, generating a parameter model taking the attribute information of the primitive as a variable according to the primitive, the type of the parameter model and the constraint condition.
Specifically, the processor acquires the primitive, the type of the parameter model and the constraint condition, and generates the parameter model using the attribute information of the primitive as a variable according to the primitive, the type of the parameter model and the constraint condition.
In this embodiment, parameters for constructing the model are obtained through attribute information of the primitive.
In one embodiment, generating a parametric model with attribute information of a primitive as a variable according to the primitive, the type of the parametric model and a constraint condition comprises: generating a parameter model frame according to the type of the parameter model and the constraint condition; and adding the primitive into a parameter model frame to be drawn to obtain a parameter model taking the attribute information of the primitive as a variable.
Wherein, the constraint condition refers to an additional condition for the relationship between the graphs. Variables are concepts in computer language that can store a result of a computation or can represent a value. Variables may be accessed by variable names. In an instructional language, variables are usually variable; but in purely functional languages (such as Haskell), the variables may be immutable.
Specifically, a constraint condition is preset, one or more items of attribute information of the primitive are used as variables, the processor obtains a parameter model type and the constraint condition, a parameter model frame is generated according to the parameter model type and the constraint condition, and the primitive is added into the parameter model frame to be drawn to obtain a parameter model with the attribute information of the primitive as variables.
In this embodiment, a parameterized model can be established through the parametric model and the constraint conditions.
In one embodiment, further comprising: receiving a parameter modification instruction, and modifying parameter values and corresponding constraint conditions according to the parameter modification instruction; and adjusting the parameter model according to the modified parameter value and the constraint condition.
The parameter modification instruction refers to an instruction generated by modifying a parameter of a constructed model, for example, the processor obtains an operation of modifying attribute information in a parameter model constructed by using attribute information of a primitive as a variable to generate a corresponding parameter modification instruction.
Specifically, the processor receives a parameter modification instruction, modifies a parameter value and a corresponding constraint condition according to the parameter modification instruction; and adjusting the parameter model according to the modified parameter value and the constraint condition. For example, the processor obtains a change in the length of the primitive from S1 to S2, where S2 is greater than S1, and generates a new parametric model based on the modified parameter values S2 and constraint condition rendering.
In this embodiment, the construction of the parameterized model can be adjusted by modifying the parameters.
According to the data processing method, the establishment of the parameterized model is realized by analyzing the Revit family file to obtain the primitive information. The following describes specific steps of the data processing method with reference to a detailed embodiment, as shown in fig. 4:
(1) loading a Revit family file in a Document loading mode to obtain DOM structure data, and taking all elements ElementCollector through Document;
(2) traversing DOM structure data to obtain all types of primitives;
(3) analyzing the Revit family file by using the C # to obtain a primitive operation function;
(4) according to the primitive operation function, different analyses are carried out on different primitives to obtain attribute information of the primitives;
(5) storing all types of primitives and attributes of the primitives into an XML file;
(6) reading and analyzing an XML file to obtain attribute information of a primitive;
(7) reading primitive generation mode in attribute information of primitive to determine construction type of model
(8) And processing the primitive modeling by using the attribute information of the primitive as a parameter of the model and drawing a function through an Operation Control Center (OCC) in an open source modeling library.
The parametric modeling is mainly composed of a graph, parameters, variables and constraint conditions, and as shown in fig. 6, the graph can be secondarily rendered through the set variables and constraints.
It should be understood that, although the steps in the flowcharts related to the embodiments as described above are sequentially displayed as indicated by arrows, the steps are not necessarily performed sequentially as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
