Specific embodiment
In the following description, numerous specific details are set forth in order to facilitate a full understanding of the present invention.But the present invention can be with
Much it is different from other way described herein to implement, those skilled in the art can be without prejudice to intension of the present invention the case where
Under do similar popularization, therefore the present invention is not limited to the specific embodiments disclosed below.
Secondly, the present invention is described in detail using schematic diagram, when describing the embodiments of the present invention, for purposes of illustration only, showing
It is intended to be example, the scope of protection of the invention should not be limited herein.
Refering to fig. 1, Fig. 1 is a kind of process of the method for CAD diagram paper modeling underworkings three-dimensional scenic provided by the invention
Schematic diagram.The step of this method includes:
By being read out to the data in CAD diagram paper, the data type read is distinguished in analysis, by different types of data format
It turns to and draws the 3-D graphic basic data that scene needs.
By graphics engine rendering three-dimensional graphics basic data, tunnel threedimensional model is obtained, is realized by graphic editor
To the editor of three-dimensional roadway model.
It wherein, is binary system arrow by the Data Format Transform of CAD diagram paper before being read out to the data in CAD diagram paper
Measure data format.
Wherein, when the data type read is distinguished in analysis, the data type is included at least and is read out from CAD diagram paper
Vertex type, the line style of type and the text type come.
Wherein, when data format to be turned to the 3-D graphic basic data for drawing scene needs, the 3-D graphic base
Plinth data refer to the graph data that graphics engine is needed in modeling, include pattern classes, dimension of picture, figure coordinate.
Wherein, when graphics engine rendering circular foundation data obtain tunnel threedimensional model, the graphics engine is that can incite somebody to action
Basic data automatically processes into the code packet of graphical model, has the characteristics that cross-platform cross browser execution.
Wherein, when graphic editor realizes the editor to three-dimensional roadway model, graphic editor is that front end scripting language is opened
The graphical authoring tools of hair have the function of drawing importing, scene editor, graphic elements deployment, save data.
Exemplary, in terms of the call format of CAD diagram paper, the preservation format of common CAD diagram paper is generally dwg format, needs
It is converted into vector data form.CAD diagram paper is opened using CAD software for editing, saves as the vector data using dxf as suffix name
Format.It is required that establishing single line Roadway model, if drawing is two-wire Roadway model, need using the line tool in CAD editing machine
Along tunnel, trend establishes single line Roadway model figure layer, and single line tunnel figure layer is saved as vector data form.
In terms of handling drawing data, the drawing of vector data form is to carry out tissue in the form of text, passes through file
System reads data and is transferred in the running memory of browser in a text form.Scanning is read in browser execution memory
Drawing text data, navigate to content area, take out content part, the sweep object in content part will scan a little pair
As, lines object, text object classification storage in memory.By the data of classification storage, by corresponding transcode, by point pair
As, the attribute information in lines object, text object, is converted according to fixed format, obtain 3-D graphic basic data.
