Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are more clearly understood, below in conjunction with the accompanying drawings to this hair
Bright embodiment is described in further details.Here, the schematic description and description of the present invention is used to explain the present invention, but simultaneously
It is not as a limitation of the invention.
As shown in Figure 1, a kind of online displaying side an embodiment of the present invention provides Building Information Model BIM difference in version
Method, intuitively rapidly to show existing difference between the different editions of same BIM, this method includes：
101：The corresponding object tag JSON files of BIM are obtained, the attribute information of BIM is extracted from JSON files；
102：The threedimensional model of BIM is drawn out at browsing device net page end according to the attribute information of BIM；
103：The attribute information of the BIM of different editions is compared, determines the model being had differences in different editions BIM
Component；
104：The model component being had differences in different editions BIM is indicated on the threedimensional model of BIM.
In one embodiment, in above-mentioned steps 101, in order to promote the speed for obtaining BIM attribute informations, Fast Drawing BIM
Threedimensional model, the JSON files of the attribute information comprising BIM can be cut into multiple subfiles, while to multiple subfiles
The reading of data is carried out, avoids causing to generate the drawbacks of data reading speed is slow because JSON files are excessive.In implementation, BIM is obtained
Corresponding object tag JSON files extract the attribute information of BIM from JSON files, can be there are many embodiment.For example,
As shown in Fig. 2, it may include steps of：
201：The corresponding object tag JSON files of BIM are obtained, calculate the size of JSON files；
202：By JSON files compared with default threshold value；
203：When the size of JSON files is more than default threshold value, JSON files are cut into multiple sizes no more than threshold
The JSON subfiles of value；
204：Multiple JSON subfiles are loaded to the Buffer object of browser, extract BIM in multiple JSON subfiles
Attribute information.
In one embodiment, predetermined threshold value can be there are many embodiment.For example, in order to improve loading velocity, and it is unlikely
It is cut through in file more, default threshold value can be arranged to 20MB：When the size of JSON files is more than 20MB, by JSON texts
Part is cut into multiple JSON subfiles no more than 20MB.In the Buffer object of the multiple JSON files of loading to browser,
Since JSON files have been cut into multiple subfiles, multiple subfiles can be loaded simultaneously, improve loading velocity, avoid because
It is long to load an excessive JSON document time, causes loading efficiency low, influences the drafting efficiency of threedimensional model.
In one embodiment, in above-mentioned steps 102, draw out BIM's at browsing device net page end according to the attribute information of BIM
Threedimensional model, can be there are many embodiment.For example, as shown in figure 3, the threedimensional model of BIM can be drawn according to following steps：
301：The tinter of browser is called according to the triangular plate member of the attribute information rendering model component of BIM；
302：According to the threedimensional model of the triangular plate of each model component member composition BIM；
303：The threedimensional model of BIM is shown at browsing device net page end.
During one is implemented, in above-mentioned steps 104, indicate what is had differences in different editions BIM on the threedimensional model of BIM
Model component, can be there are many scheme.For example, it as shown in figure 4, may include steps of：
401：Determine the difference type for the model component being had differences in different editions BIM, the difference type includes：Newly
Increase, be deleted or modified；
402：On the threedimensional model of BIM, with the model being had differences in different display mode mark different editions BIM
Component.
In one embodiment, in above-mentioned steps 402, to be had differences in different display mode mark different editions BIM
Model component, can be there are many embodiment.For example, different colors can be set for different difference types in advance,
On the threedimensional model of BIM, the model component for increasing newly, being deleted or modified is shown as different colors, makes user not only can be fast
In place of speed observes difference, and it is known that the type of difference.For another example different difference types can also be set not in advance
Same brightness, on the threedimensional model in BIM, is shown as different brightness, equally by the model component for increasing newly, being deleted or modified
Can the type of difference be rapidly intuitively presented to user.
In one embodiment, a BIM model is modified in its second version, and first version has 4
Rectangular column, and then become in second version for 8 rectangular columns, being related to 2 rectangular columns among these does not change, and 2
Root rectangular column highly halves, and has in addition newly increased 4 rectangular columns.It, can there will be differences on the threedimensional model of BIM in implementation
Model component be shown as different colors, for example, can two rectangular columns of modification be shown as the first color (red), newly
4 rectangular columns increased are shown as the second color (yellow), and the model component of difference may be not present then without coloring.At this point, with
Family can grasp rapidly difference by observing the BIM threedimensional models of different editions.
In one embodiment, much information can be included by stating the attribute information of BIM.For example, the attribute information of BIM can wrap
It includes：One of model component tri patch index information, material information, location information and cost information of BIM or arbitrary group
It closes.
In one embodiment, model component tri patch index information can include plurality of kinds of contents.For example, model component three
Edged surface piece index information can include vertex information array, normal information array, texture information array etc..
Based on same inventive concept, a kind of Building Information Model BIM difference in version is additionally provided in the embodiment of the present invention
Online displaying device, as described in the following examples.Due to the online displaying device solution of Building Information Model BIM difference in version
Certainly the principle of problem is similar to the online methods of exhibiting of Building Information Model BIM difference in version, therefore Building Information Model BIM editions
