To keep the purposes, technical schemes and advantages of the embodiment of the present application clearer, below in conjunction with attached drawing to the application Technical solution be clearly and completely described, it is clear that described embodiment is some embodiments of the present application, rather than Whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making creative work premise Under every other embodiment obtained, shall fall in the protection scope of this application.

The term " includes " and " having " and their any deformation being previously mentioned in the entry of the embodiment of the present application, it is intended that It is to cover and non-exclusive includes.Such as the process, method, system, product or equipment for containing a series of steps or units do not have It is defined in listed step or unit, but optionally further comprising the step of other are not listed or unit, or optionally It further include the other step or units intrinsic for these process, methods, product or equipment.

The embodiment of the present invention is further introduced with reference to the accompanying drawing.

Fig. 1 is the construction method flow diagram of virtual networks in a kind of game provided in an embodiment of the present invention.Such as Fig. 1 institute Show, this method comprises:

S110 obtains editor's information of the first road network.

Editor's information of first road network includes the road description of the crossing description and the first road network of first via net.This first Crossing position of the description including first point of road network and the crossing attribute corresponding to first point；The road description packet of first road network Include the first line segment group position and the road attribute corresponding to the first line segment group.

First line segment group cutting is the according to the road attribute of preset point of contact setting rule and the first road network by S120 The road line segment group of one road network and the crossing line segment group of the first road network, and determine the segmental information and first at the crossing of the first road network The segmental information of the road of road network.

The segmental information at the crossing of first road network includes the crossing line segment group of first point and the first road network；First road network Road segmental information include the first road network road line segment group.

S130 according to the segmental information at each crossing of the first road network, corresponding to first point of crossing attribute and corresponds to The road attribute of the crossing line segment group of first road network generates the corresponding virtual crossing in each crossing of the first road network.

S140, the road of the road line segment group according to the segmental information of every road of the first road network and corresponding to the first road network Road attribute generates the corresponding virtual road of every road of the first road network.

S150 combines the corresponding virtual crossing of the first road network and virtual road, generates the virtual networks of the first road network.

It describes in detail below to above-mentioned steps S110-S150.

In above-mentioned steps S110, road network information that editor's information of road network can be indicated by Points And lines.Wherein, point For determining position, for example, can indicate position by the longitude and latitude or coordinate of point.Line can be closed by the connection between point To indicate, which can be used to identify road for system；According to the position of the line and point corresponding with the line, the position of road can be determined It sets.In some instances, point or line can have attribute, which can be identified by way of label.All It may include some for identifying the point that road crosses, this is used to indicate the point that road crosses and is properly termed as crossing mark in point Point.Wherein, the line between joint is properly termed as road markings line segment.

For example, Fig. 2 shows editor's information of road network may include multiple points and a plurality of line.Wherein, point 200 and point 204 For crossing；Line segment group between point 200 and point 204 is that " 200,201,202,203,204 ", which is road.

In specific implementation, editor's information of road network can be edited by developer.As an example, developer can be with Using map as reference, to edit editor's information of road network, for example, can be using OSM as the reference information of editor's road network.Separately Outside, in order to cope with the editor of large-scale road network, an OSM exploitation server can be built to facilitate multiple person cooperational editor's road network Edit information.Exploitation terminal can obtain editor's information of road network by exploitation server, can also edit the editor of road network Information.

In some embodiments, editor's information of the first road network can be obtained by developer's direct editing, be also possible to The editor's information for the second road network edited according to developer is divided to obtain.

As an example, above-mentioned steps S110 can be achieved by the steps of:

Step 1.1) obtains editor's information of the second road network.Editor's information of second road network includes the road of the second road network The road description of mouth description and the second road network；

Step 1.2) corrects editor's information of the second road network according to preset modification rule, obtains modified second road network Editor's information；

Step 1.3) is divided into multiple first by editor's information of modified second road network according to preset division rule Editor's information of road network.Wherein, the preset division rule may include: the first adjacent road network editor's information between include The part of overlapping.

For above-mentioned steps 1.1), the crossing of above-mentioned second road network describes the position including second point and corresponds to second point Crossing attribute.The road description of above-mentioned second road network includes second line segment group position and the road category corresponding to second line segment group Property.

For above-mentioned steps 1.2), which can be an error detection process, the editor of editor's information of the second road network Cheng Zhong can only generally guarantee that format is correct, but can not check whether data comply with standard.It may insure by amendment scheme subsequent The available correct data of algorithm.There are two types of amendment schemes, and one is the editor's letters for directly prompting the second road network of developer Cease it is problematic, so that developer re-starts editor.Another is to be automatically corrected number according to preset modification rule According to.Which kind of is specifically depended on the difficulty for being automatically repaired realization using.

Above-mentioned preset modification rule may include following one or more:

Judge that the intersection between the second line segment of intersection whether there is second point, if it does not, increasing intersection pair The second point answered；

The trend of second line segment group is corrected, so that the corresponding line segment trend of same section of road is consistent；

Second point and second line segment are merged or split, so that being connected between second point by individual second line segment It connects.

For example, as shown in figure 3, for indicating the line segment group " 12,13,14,15 " and " 3,4,5,6 " cross, still of road There is no joints.

It, can first to line segment, " 13,14 " " 4,5 " near joint with line segment when increasing the corresponding second point of intersection It interrupts, then carries out vertex merging again and obtain joint.As shown in figure 4, can by be used to indicate road line segment group " 12,13, 14,15 " and " 3,4,5,6 " squeeze out upwards, and a circle is generated near vertex, and squeeze out, are allowed to for indicating upwards The line segment group " 12,13,14,15 " and " 3,4,5,6 " extrusion and the intersection of the extrusion of circle, are carrying out phase reducing, and retain on road After the line of bottom, realize to line segment " 13,14 " and line segment " 4,5 " interrupt near joint, then will interrupt and to carry out a vertex and melt Conjunction obtains joint.

For another example as shown in figure 5, for indicate road line segment group " 51,52,53,54 " be same section of road, still, " 51,52 " " 53,54 " move towards is inconsistent with line segment for line segment.At this point it is possible to adjust line segment trend.For example, as shown in fig. 6, logical Cross adjustment line segment " 53,54 " trend so that the line segment group for indicating road " 51,52,53,54 " trend is consistent.

For above-mentioned steps 1.3), in some embodiments, forms and deposit between the component (for example, road or crossing etc.) in city In very strong relevance.As space increases, the type of component is also continuously increased, and the network that is mutually related between component is multiple Miscellaneous degree will be with the increase of the speed of geometry grade.By splitting these associations, the demand to hardware can be reduced.

After the size of entire scene is more than a certain size, whole load is nearly impossible.Segmentation spatially Just at inevitable choice.Dividing grid by certain unit-sized is a more commonly used preset division rule.In addition, The preset division rule will keep associated integrality when can also including: piecemeal, even if the content that is mutually related is super Region should be also in inside a block out；In order to avoid meeting difficulty when piecemeal, the generation of the object of super large is avoided as far as possible. Such as the road of very long several pieces of a leap that do not divide.This is also unfavorable to game performance.

It in one example, can be according to presetting size for editor's information of the second road network as shown in Figure 7 Grid carries out Preliminary division to the layout of the second road network.As shown in connection with fig. 8, can by the line segment and point in the second road network, to Upper extrusion；And a cube is copied on the grid for needing piecemeal, becoming for the cube can be the side length of grid Twice.The figure squeezed out on grid is cut using the cube, retains bottom line segment and point, obtains the line of the first road network Section and point.Aforesaid operations, the line segment and point of available each first road network successively are carried out to each grid.It is implementing When, can once cut completion, then successively execute above-mentioned steps S110-S150, be also possible to every time for grid into Row cutting after obtaining a piecemeal, executes above-mentioned steps S110-S150, after the completion of execution, then carries out the cutting of next piecemeal. Furthermore it is possible to execute above-mentioned steps S110-S150 for each piecemeal by way of executing parallel.

In addition, needing to merge to obtain final result after obtaining virtual networks for each piecemeal.It, should based on this Method further include: the virtual networks of corresponding each first road network of the second road network are merged, the virtual networks of the second road network are obtained.

Editor's information for the road network corrected, it may be convenient to distinguish crossing and connect the road at crossing.With this It is a bit foundation, further crossing is separated, to be respectively processed.

In one example, for some special crossings, the virtual crossing of special rotary island type can be generated.It is based on This, above-mentioned steps S130 can specifically include:

Step 2.1), from the segmental information at the crossing of the first road network, separation outlet attribute is the cutting at rotary island crossing Information.

For example, as shown in figure 9, segmental information may include, the 1: 91 and first line segment " 91,92 ", " 91,93 ", " 91,94 ", " 91,95 " and " 91,96 " the first line segment groups constituted.

For the segmental information at each rotary island crossing, it is performed both by following steps 2.2)-step 2.5):

Step 2.2), according to the positional relationship of the crossing line segment group at rotary island crossing and corresponding to the road of the crossing line segment group Attribute, every two adjacent crossing line segment generate a U-shaped outline border.

For example, as shown in Figure 10, according to the first line segment " 91,92 " and " 91,93 " positional relationship and the first line segment " 91, 92 " and " 91,93 " it is corresponding have a lot of social connections, generate U-shaped outline border 1001.

Step 2.3) generates the blending portion of external road according to the corresponding multiple U-shaped outline borders in rotary island crossing.

For example, as shown in figure 11, the blending portion of external road is generated according to the corresponding multiple U-shaped outline borders in rotary island crossing 1101。

Step 2.4) generates the inside astragal at rotary island crossing according to the first of rotary island crossing position and crossing attribute Part.

For example, as shown in figure 12, it is raw according to the size of the first of rotary island crossing: 91 position and the crossing of the first road network At the inside astragal part 1201 at rotary island crossing.

The blending portion of the external road at rotary island crossing and internal astragal part are merged, and carried out by step 2.5) Road surface textures obtain virtual rotary island.

In one example, above-mentioned steps S130 can specifically include following steps, to realize the life at dummy general crossing At:

Step 3.1), from the segmental information at the crossing of the first road network, separation outlet attribute is the cutting at general crossing Information.

As shown in figure 13, general crossing segmental information may include, the 1: 131 and first line segment " 131,132 ", " 131,133 ", " 131,134 " and " 131,135 " the first line segment groups constituted.

Step 3.2), according to the positional relationship of the crossing line segment group at general crossing and corresponding to the road of the crossing line segment group Attribute, every two adjacent crossing line segments translate the specified width, which width on road outward, obtain a general crossing intersection point.The specified width, which width It is determined according to the road attribute for corresponding to every two adjacent crossing line segments.

For example, as shown in figure 14, according to the crossing line segment " 132,134 " and " 133,135 " of first road network at general crossing Positional relationship and road width, every two adjacent crossing line segments translate the specified width, which width on road outward (for example, road width Half), general crossing intersection point 141,142,143 and 144 is obtained respectively.

Step 3.3) determines the outer profile at general crossing according to the corresponding intersection point in each general crossing and point of contact, based on logical Road surface and curb textures are carried out with the outer profile at crossing.

Wherein, point of contact can be that the point of contact that rule determines is arranged according to preset point of contact in aforementioned S120.

In one example, based on intersection point 151,152,153 and 154 as shown in figure 15, which can be based on Figure 14 Shown in method hair determine that each intersection point does vertical line to original path, at most obtain two vertical line intersection points (may also only one or Person does not have, and three roads as shown in figure 16 cross, and point 161 i.e. no corresponding vertical point crosses for 4 roads, if vertical line In the another side of joint, being considered as does not have vertical line intersection point in original road), for example, intersection point 151 and 152 is on same road Hang down point 155 and 156, takes the point 155 farthest from road joint, as point of contact (when not having vertical line intersection point, then taking joint).

Vertical line section is done with road line segment after point of contact extrapolation certain distance, the width of the vertical line section is equal to road width.Sequentially Connection vertical line endpoint and intersection point have just obtained the outer profile at crossing, for example, as shown in figure 17 1701.Done at point of contact it is round and smooth, Obtain round and smooth corner.

Step 3.4), on the road surface textures at general crossing, the corresponding position in point of contact generates zebra stripes, obtains dummy general Crossing.

Wherein, zebra stripes one is perpendicular to point of contact are chiefly used in T font crossing, angle changing rate is orthogonal there are two types of form Crossroad etc..Another kind is two intersection point line directions, is chiefly used in the biggish crossing of tilt angle.The setting of the zebra stripes Mode can be preset, for example, can edit in the attribute at crossing.

Each road is all a line segment group, traverses these line segment groups, generates each road.When generating road, The part of bend can individually be handled.In one example, above-mentioned steps S140 can specifically include:

Step 4.1) generates every road according to the corresponding road width of road line segment group of every road of the first road network The outline border on road；

Step 4.2) successively judges whether there is racetrack portion according to the road description of every road of the first road network；

The road description of the road is separated into curved by step 4.3) for there are the roads of racetrack portion in the first road network Road part and straight way part；

Step 4.4) is moved towards to carry out bend along bend based on the outline border of road according to preset curved road surface textures rule Partial road surface textures；

Step 4.5), according to preset straight way road surface textures rule, the outline border based on road carries out the road surface of straight way part Textures；

The road surface of step 4.6), road surface and straight way part that the racetrack portion of the road of racetrack portion will be present merges, and According to there are the corresponding road attributes of the road of racetrack portion to generate curb and graticule, the road there are racetrack portion is obtained Virtual road.

Step 4.7), according to preset straight way road surface textures rule, is based on the road for the road of racetrack portion is not present The outline border on road carries out the road surface textures of straight way part, and generates curb according to the corresponding road attribute of the road line segment group of the road And graticule, obtain the virtual road of the road.

In step 4.2), bend can be separated by the angle of abutment points by independent processing.In each point can be with Which the point for obtaining his adjoining is.The abutment points on each vertex are one or two.Illustrate that he is road if it is one Endpoint, do not need to calculate.If there are two abutment points, illustrate that he is the middle section of road.Abutment points and current vertex can To form two sides, the angle that this two sides are formed is calculated.If angle is less than first threshold, it may be considered that being curved Road, wherein the setting value can predefine.

In some embodiments, above-mentioned steps 4.4) it can specifically include following steps:

Judge whether the corresponding turning amplitude of racetrack portion meets road service requirement；

If do not met, the outline border of the road of racetrack portion is smoothed, and based on the outline border after smoothing processing, It moves towards to carry out road surface textures along bend according to the outline border of road；

If met, the road surface textures of progress racetrack portion are moved towards along bend based on the outline border of road.

Wherein, road service requirement can be that turning amplitude cannot be excessive.For example, abutment points and current vertex can form Two sides calculate the angle that this two sides are formed.If angle is less than second threshold, it may be considered that being not meet road Service requirement, wherein the setting value can predefine, which can be greater than second threshold.In addition, road service requirement It can also include other requirements, can specifically be set according to the running requirement of real road.

In step 4.7), racetrack portion and straight way portion point are merged, the generation on road surface just completes, then again In addition curb and graticule.UV (mapping coordinates system) segmentation on road surface follows road surface to move towards, so as to when adding wheel trajectories etc., more It is convenient.In addition, the UV of textures can also be divided by certain length, guarantee every section of UV all in 0~1 section.

Wherein, UV refers to the coordinate system of textures.For example, the UV on vertex refers to that vertex is projected to the seat of textures by certain rule Coordinate in mark system.This projection is a kind of three-dimensional open and flat transformation to two-dimensional textures of model.He determines textures such as What is covered on model.We just need to calculate its corresponding UV value when generation vertex, just can guarantee that textures correctly paste On model.

The construction method and device of virtual networks in a kind of game provided in an embodiment of the present invention.The first road network can be obtained Editor's information, editor's information of first road network include first via net crossing description and the first road network road description, should Crossing position of the description including first point of first road network and the crossing attribute corresponding to first point, the road of first road network are retouched It states including the first line segment group position and corresponding to the road attribute of the first line segment group, road network is described by Points And lines with this, drop Low editor's difficulty of editor's information of road network, and the resource needed when operation；By the way that rule is arranged according to preset point of contact It is road line segment group and crossing line segment group by the first line segment group cutting with the road attribute of the first road network, and is based on the first road network The segmental information at crossing and the segmental information of road of the first road network generate the corresponding void in each crossing of the first road network respectively The corresponding virtual road of every road at quasi- crossing and the first road network；To finally virtual crossing and virtual road be combined, be generated Virtual networks can be divided according to complexity with this, and are respectively processed by virtual networks, reduce the volume of road network The complexity of volume information reduces interfering with each other for data in treatment process, improves the building efficiency of virtual networks, reduce While cost, the accuracy rate of virtual networks is higher.

The embodiment of the present invention can also be realized according to precision not by the modification rule of editor's information of the road network of offer Editor's information of high road network generates the higher virtual networks of precision, and accuracy rate with higher, while reducing road network Editor's information editor's difficulty.In addition, divided by the modified editor's information of the second road network by block, and respectively into Row processing can reduce requirement of the treatment process to hardware, and improve the formation speed of virtual networks.

In addition, can also be carried out to crossing and road according to complexity further in the building process of virtual networks Subdivision, and is respectively processed, and the complexity of editor's information of road network is lower, data the case where interfering with each other in treatment process Less, the building of virtual networks is more efficient, and cost is lower, and the accuracy rate of virtual networks is higher.

In some embodiments, in textures, if crossing has some seams and occurs when encountering big corner.In road network The editor that edits information and when amendment, can keep the normal of crossing junction unanimously can effectively avoid crossing seam. Furthermore it is also possible to be modified as follows:

As an example, it is generated in the joining place of the corresponding virtual crossing of virtual networks of the first road network and virtual road Pavement or gutter.To use the modes such as pavement or gutter to cover seam.

As another example, if encountering small gap, interface can be grouped, then vertex merging is to together may be used With very good solution seam problems.

In addition, also having seam problems in curb and ground, a part of area can be overlapped in textures.Dan Shi, can be with Avoid plane from being overlapped as far as possible, if the case where encountering overlapping, be staggered up and down, and adjacent edge generate one it is vertical Face avoids seeing gap when camera lens level.

In some embodiments, this method further include: the road outline border based on virtual networks, according to presetting virtual adjunct Create-rule generates the virtual adjunct in roadside.

It sometimes appear that the problem of adjunct is overlapped, the embodiment of the present invention can also provide when multilayer adjunct generates Collision rule.

As an example: collision rule -- remove: the adjunct covered by the higher attached object point of priority removes；

As another example: collision rule -- it squeezes: the adjunct in a certain distance from the higher adjunct of priority It is squeezed.

In some embodiments, virtual networks can be supported according to hypsography.The height of road surface curve is by locality The height of shape obtains.Since the realization of all virtual networks before is all in one plane completed, collected height is not P.y can be directly stored to, and (P is locative variable, and y represents vertical direction.) in, and need temporarily to exist in other variable. It is just filled P.y is highly stored to when to the last constructing road surface.

In further embodiments, in order to which solve can be by difference polishing, with landform between each sampled point of road network Not the case where actual conditions are not met, and are easy to appear interspersed phenomenon.This method can also specifically include the steps of determining that virtually Shape；The virtual networks are projected on the Virtual Terrain of same position, and Virtual Terrain is smoothed.

In some embodiments, virtual networks can also be edited.

It is, for example, possible to use a set of indexes by road and crossing, the attribute of every road and crossing is arranged, and The object palette of corresponding accessory attribute.Individual attribute can be arranged in every road, each crossing.Each index has its correspondence Geometry, for storing corresponding data.Unique identification corresponding with road can be used to indicate in index, so as to Retain editor's information of unchanged road network when road network iteration.
