Step S30, realized based on the Internet images storehouse (Web Graphics Library, WebGL) technology it is cross-platform, lead to Cross the color applying drawing that indoor map Engine draws flow carries out map;
It should be noted that the indoor three-dimensional map engine can be based on HTML (HyperText Markup Language, HTML) framework realization, preferably HTML5.Based on HTML5 frameworks, the Internet images storehouse (Web can be used Graphics Library, WebGL) the cross-platform displaying for realizing indoor map of drawing technique, realized by WebGL technologies Realize that the display problem in the indoor map of different platform, such as user pass through browsing on mobile phone or computer by a set of code Device, the displaying of indoor map can be carried out by different types of browser.
Render and can call rendering intent by starting animation, then call view rendering side carrying out indoor three-dimensional map Method and calling WebGL render to carry out indoor three-dimensional map.
The schematic flow sheet of indoor three-dimensional map engine renders as shown in Figure 4, when the indoor three-dimensional map of progress renders, Map corresponding to ID is first turned on, loading, analytic map pattern, after pattern is parsed, judges whether that atural object, which is not present, to be clicked on Action listener function, if it does not exist, then addition atural object clicks on action listener function, monitored if it is present starting, after calling Platform asks atural object data, and carries out data conversion, then initializes scene, floor data is converted into atural object atural object mesh Mark 3D objects are simultaneously added in scene, and extraction floor data is parsed and changed, according to the floor atural object number after parsing, conversion It is added to according to the target 3D objects of construction in scene, and starts animation, calls rendering intent, recycles recurrence amending method unlimited Circulation, then call view rendering method and call WEBGL rendering intents to be rendered so as to realize to indoor three-dimensional map, also The authenticity of atural object, improves Consumer's Experience in former indoor three-dimensional map.
It is understood that after the indoor map data being managed with figure layer concept are got, indoor ground can be based on Figure Engine draws flow carries out the color applying drawing of map, so it is easy to understand that the indoor map Engine draws flow refers to, leads to Visualized map engine is crossed to go to show indoor map.
In the specific implementation, rendered to the figure layer data, with each floor maps corresponding to getting, described in displaying Floor maps, to realize the displaying to indoor map.Go to realize the drafting of floor maps based on above-mentioned each figure layer data, than it Floor maps are drawn using floor maps data as whole removing, it is more efficient and quick to divide the mode of figure layer, Ke Yirang User quickly sees the displaying of indoor map.Also, in order to further accelerate map acquisition speed, due to entering for figure layer Go division, certain priority can also have been carried out to each figure layer parameter corresponding with each figure layer data and divided, such as, for reality Now quick displaying, can first show that user may most think the information first seen, floor figure layer, atural object figure layer and communal facility can be set Figure layer is the first priority, and it is the second priority that the information such as text marking and picture mark, which can be set,., can be excellent when user watches First render and show the information of the first priority, then show the information of the second priority, so that obtaining user can quickly obtain Effective information.When the network environment residing for smart mobile phone is less unobstructed, this kind of mode can preferably weaken network speed difference band Negative influence, also achieve effective collection for indoor map data and effectively classification, also improve indoor map and show Reaction speed.In addition, by setting certain figure layer parameter priority, it is ensured that user can get effective room On the premise of interior information, accelerate the displaying speed of map.
It is understood that after the indoor map data are carried out with floor and figure layer division, each layer can be obtained Floor maps data, and then the figure layer data of floor maps data are got, the figure layer data can be rendered, to obtain Corresponding each floor maps.
In the specific implementation, after seven parts of floor maps corresponding with seven parts of floor maps data are had been obtained for, User can individually carry out the viewing of each layer map by floor maps, still, unified visual angle is based on for entirely building to realize Build space to be observed, the floor maps can be spliced, using spliced map as indoor map, you can obtain room Interior map.User can more clearly from observe whole target structures thing by direct viewing indoor map.
Step S40, by setting two Three-dimensional Display parameters, to realize the two of engine map three-dimensional different display effects;
It is understood that the difference of the observation visual angle of two-dimensional map and three-dimensional map causes the letter that user can get Breath type has differences, and both can watch two-dimensional map simultaneously for the ease of user or can watch three-dimensional map, and dimension can be set Selection instruction is spent, the dimension selection instruction chooses the dimension map for being currently needed for display for user and display is rendered good Dimension map.For example when user needs to show three-dimensional map, it is according to the current dimension that the dimension selection instruction determines For three-dimensional.
In the specific implementation, it is determined that display three-dimensional map after, by the indoor map data including three-dimensional map data Rendered, to get corresponding three-dimensional indoor map;Or in order to accelerate display speed, can render in advance completion this three Indoor map is tieed up, when user inputs dimension selection instruction, directly displays the three-dimensional indoor map of the rendered completion.
It is understood that in order to show three-dimensional indoor map, the indoor map data may include three-dimensional modeling data With non-three-dimensional modeling data, the three-dimensional modeling data refers to the data that three-dimensional shape is recorded by wire frame, the non-three-dimensional mould Type data refer to the three-dimensional modeling data carry out Texture mapping color and lines information, with reference to three-dimensional modeling data with it is non- Three-dimensional modeling data, which is rendered, can just show clear and the colorful one floor maps.
Further, first the non-three-dimensional modeling data can be loaded, to obtain corresponding relief-map.Wherein, The relief-map is the cartographic information without embodiment threedimensional model, such as, backcolor and building substance markers etc..
Further, after relief-map is got, the relief-map can be carried out by the three-dimensional modeling data Draw, to get indoor map.
It is understood that due to only delineating relief-map, user still can not find out specific and detailed building Thing picture, so, after relief-map corresponding to getting, the relief-map can be carried out by the three-dimensional modeling data Draw, to obtain corresponding indoor map, you can get the indoor map that user can be observed how the details of building. Wherein, the reason for first obtaining relief-map is that the data volume of three-dimensional modeling data is larger, so by for threedimensional model number Need to consume larger amount of calculation according to cartographic information corresponding to render acquisition, in order to allow user quickly can observe ground Figure, can be by with three-dimensional modeling data successively dividually draw to non-three-dimensional modeling data, also, can also avoid same When handle three-dimensional modeling data and non-three-dimensional modeling data equipment operand it is excessive the problem of.
In the specific implementation, relief-map can not clearly see the specific object of interior clearly, still, with getting model Secondary drafting is carried out after figure again to get corresponding indoor map, does not divide and three-dimensional directly enters with non-three-dimensional modeling data than it Row renders figure, the technical scheme that the present embodiment provides, user can be allowed more stably to check indoor two three-dimensional maps, and allow and set Standby operand tends to be steady.
It is understood that because the ratio data of threedimensional model is big, the first display of engine map acquiescence is except threedimensional model Other data messages, it is then asynchronous to load threedimensional model one by one, it is displayed immediately on after the completion of loading above map, so as to realize three Dimension map is fade-in formula and enters map scene.
Step S50, by preferentially drawing one floor data of display, and other floor datas are asynchronously shown, so as to reach The effect quickly shown;
In the specific implementation, by first handle floor maps data acquisition to corresponding to each floor maps, it is finally indirect again Ground gets indoor map, does not divide floor than it and directly renders indoor map, the drafting display mode of the present embodiment is easy to The management for floor maps is realized, user can also be allowed quickly to get map, because user first can be shown to user The floor maps at place, then other floor maps are shown, based on this kind, orderly floor maps are shown, i.e., initial by setting The mode for loading floor is come after the completion of quick one layer of displaying of first loading, continues to load other floors, accelerates display speed so as to reach The technique effect spent and allow user quickly to get map.
Because the data of threedimensional model are bigger, indoor three-dimensional map engine acquiescence first show except threedimensional model other Data message, it is then asynchronous to load threedimensional model one by one, it is displayed immediately on after the completion of loading on map, so as to realize three-dimensional atural object It is fade-in formula and enters map scene.
