Include:
Step 101: obtaining the texture mapping being pre-designed.
Wherein, the texture mapping includes: the first texture mapping applied to community residential building, applied to office building
Two texture mapping, the 4th texture mapping applied to Hotel Buildings, are applied to quotient at the third texture textures applied to hospital architecture
5th texture mapping of field building, and be applied to except community residential building, office building, hospital architecture, Hotel Buildings, market building
Except other building the 6th texture mapping.Specifically, as shown in Fig. 2, to be pasted applied to the first texture of community residential building
Figure;As shown in figure 3, for the second texture mapping applied to office building;As shown in figure 4, for the third line applied to hospital architecture
Manage textures;As shown in figure 5, for the 4th texture mapping applied to Hotel Buildings;As shown in fig. 6, being to be built applied to market
5th texture mapping;As shown in fig. 7, for applied to except community residential building, office building, hospital architecture, Hotel Buildings, market building
Except other building the 6th texture mapping.
I.e. the embodiment of the present invention is by classifying to building in navigation map, to utilize different texture mapping
It goes to indicate different types of building, to reach the identification for promoting each building in navigation map.In addition, being pasted for texture
The included type of figure is not limited to above-mentioned six kinds.
Preferably, the texture mapping is the window textures of building.Wherein, different types of building is on window
Design is general different, it is possible to be distinguished by the difference of window to all kinds of buildings.It therefore, can be only to navigation ground
The window area of buildings model in figure carries out the mapping of texture mapping, to reduce textures mapping area, further saves and leads
The memory of boat map.
Step 102: the object areal coordinate and the texture coordinate in the texture mapping for determining the buildings model being obtained ahead of time
Mapping relations.
Wherein, object areal coordinate be buildings model surface any point in buildings model a little for origin, with
The length direction of the buildings model is respectively the coordinate in the coordinate system that X-axis, Y-axis and Z axis are established.Texture coordinate is line
Manage textures region in any point in the texture mapping a little for origin, with the length and width side of the texture mapping
The coordinate in coordinate system established to respectively X-axis and Y-axis.
Step 103: according to the mapping relations, the texture mapping being mapped in the buildings model, is had
The buildings model of texture display effect.
The mapping relations of the texture coordinate on the object areal coordinate and texture mapping of buildings model are determined by step 102
It afterwards, then can be by the imparting of the pixel at the object areal coordinate of buildings model and texture coordinate respective pixel data, to obtain
Buildings model with texture display effect.
Wherein, after buildings model in navigation map carries out the mapping of texture mapping, still can amplify, reduce and
360 degree rotation etc. is normally shown.
The embodiment of the present invention, by the way that the texture mapping being pre-designed is mapped in the buildings model in navigation map,
So that buildings model has texture display effect, consequently facilitating user distinguishes each different building in navigation map
Recognize, improves the identification of buildings model in navigation map.
In addition, being carried out on the basis of the embodiment of the present invention is the buildings model in the navigation map to have completed
Textures, it is no longer necessary to data supplier expends a large amount of man power and materials and goes individually designed buildings model, and cost is greatly saved, and
And chart pasting method is not especially big, data volume very little, to save navigation system memory, Jin Erti to the rendering pressure of engine
The reaction speed of navigation is risen.
Preferably, step 102 includes:
Obtain the textures region in the buildings model being obtained ahead of time;
Determine the object areal coordinate in the textures region and the mapping relations of the texture coordinate in the texture mapping.
I.e. firstly the need of determining which region of surface of buildings model needs to carry out the mapping of texture mapping, thus can
Texture mapping is further mapped to these regions.
Further, the textures region is rectangular area, the object areal coordinate in the determination textures region and institute
The step of stating the mapping relations of the texture coordinate in texture mapping, comprising:
The object plane coordinate of the object areal coordinate and four vertex that determine four vertex in the textures region is corresponding
Texture coordinate;
Using interpolation computing method, according to the object areal coordinate on four vertex in the textures region and four vertex
The corresponding texture coordinate of object plane coordinate determines the corresponding texture coordinate in any point in the textures region, obtains the patch
The object areal coordinate of graph region and the mapping relations of the texture coordinate in the texture mapping.
Wherein, if the texture coordinate of four vertex correspondences of a rectangular area has determined, in the rectangular area
The texture coordinate in portion just needs interpolation to calculate.Such as the corresponding texture of four vertex (p0, p1, p2, p3) of a rectangular area
Coordinate be respectively (q0, q1, q2, q3), then rectangular area inside any point (x, y, z) can by will (p0, p1, p2,
P3) coordinate of this four points substitutes into predetermined formula and is determined, and the corresponding texture coordinate of point then pass through by
The coordinate of (q0, q1, q2, q3) this four points substitutes into predetermined formula and is determined.
In conclusion the building mould obtained using the acquisition methods of buildings model in the navigation map of the embodiment of the present invention
Type, occupied memory is less in navigation map, so that user can experience during using navigation map
Faster reaction speed, and it is capable of according to the texture mapping on each buildings model surface the destination of auxiliary positioning oneself, significantly
Improve the usage experience of user.
