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.

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.
