According to embodiments of the present invention, a kind of joining method of target object in stereo-picture is provided, as shown in Fig. 2, should Method includes:

Step S21, judges whether any two target object to be spliced is in same textures texture coordinate.

Textures texture coordinate in the application above-mentioned steps S21 can be identified with UV, define the position of each point on picture The information set.These points connect each other with 3D model, to determine the position of surface texture mapping.

Step S23, in the case where any two target object to be spliced is in same textures texture coordinate, by two The vertex for meeting preset condition in target object to be spliced is merged according to preset merging rule.

In an alternative embodiment, when being spliced using 3DS MAX to target object, in two mesh to be spliced Mark object is in same textures texture coordinate, in order to remove the redundancy vertex generated after splicing, improves the smooth degree of game, can The vertex for meeting preset condition to be merged using the control function of being carried in 3DS MAX.

The vertex that two are overlapped is merged into new summit it should be noted that can be in the process merged herein, Therefore, the former vertex that the vertex parameter of new summit is overlapped by two determines, wherein vertex parameter includes at least the UV of apex, And the TBN of apex, it is believed that the UV on two coincidence vertex is identical.

It should be further noted that since the former vertex that the parameter of new summit is overlapped by two determines, then new summit In vertex parameter, the UV of new summit is identical as the former vertex that two are overlapped, but the TBN that TBN is overlapped former vertex by two is calculated It arrives, the TBN in the vertex parameter on the former vertex being overlapped with two is not identical, therefore can cause the flaw of splicing.The application is directed to The flaw that above-mentioned reason occurs provides preset merging rule and merges method, so that at the splicing edge of object to be spliced The vertex at place is able to maintain the TBN information on former vertex, to eliminate splicing edge while removing redundancy vertex to greatest extent Flaw.

Step S25 will splice in the case where any two target object to be spliced is in different textures texture coordinates The tangent line space vector on each splicing vertex is adjusted to identical in vertex set；

Wherein, splicing vertex is the point on the splicing edge line between any two target object to be spliced, splicing edge All splicing vertex for including on edge line constitute splicing vertex set.

Herein it should be noted that working as the case where any two target object to be spliced is in same textures texture coordinate Under, it is believed that above-mentioned two target object to be spliced is that two objects in same file therefore can be to above-mentioned two Vertex in object such as merges at the operation；The case where two target objects to be spliced are in different textures texture coordinates Under, it is believed that above-mentioned two target object to be spliced is two objects in two different files, therefore, above-mentioned two Vertex in target object, which cannot merge, to be operated.

From the foregoing, it will be observed that scheme provided by the above embodiments of the present application, by judging any two target pair to be spliced As if it is no in same textures texture coordinate；The feelings of same textures texture coordinate are in any two target object to be spliced Under condition, the vertex that preset condition is met in two target objects to be spliced is merged according to preset merging rule；? In the case that any two target object to be spliced is in different textures texture coordinates, by each splicing in splicing vertex set The tangent line space vector on vertex is adjusted to identical mode, by judging whether any target object to be spliced is in same textures Texture coordinate takes target object to be spliced different measures, has reached the normal direction one of the stitching portion of object to be spliced The purpose of cause to realize the technical effect for eliminating splicing flaw, and then solves in the stereo-picture of the prior art and includes Any two target object when being spliced, since the tangent line space vector of opposite vertexes when merging is recalculated, make Tangent line space vector and the master tangent space vector that edge must be spliced are inconsistent, and the technology of flaw is generated so as to cause stitching portion Problem.

It is worth noting that, in above-mentioned stereo-picture provided by the present application the joining method of target object it is unlimited be applied to The splicing of game role also can be widely applied for advertisement, video display, industrial design, architectural design, three-dimensional animation, multimedia system It is related to the part of stereo-picture splicing in the fields such as work, game, aided education and Engineering Visual.

Still when noticeable, the software in the application above-mentioned steps for being spliced to stereo-picture, which can be, appoints Anticipating has the 3D software for editing that splicing function is carried out to stereo-picture, unlimited and above-mentioned 3D MAX.

In a kind of optinal plan that the above embodiments of the present application provide, above-mentioned steps S23, by two targets pair to be spliced Include the following steps: as the middle vertex for meeting preset condition is merged according to preset merging rule

Step S231 obtains the vertex for meeting preset condition, wherein the vertex for meeting preset condition includes two to be spliced Target object splicing after overlapping position be overlapped vertex and splice edge line splicing vertex.

As a kind of optional embodiment, in the example that user is previously selected game role replacement clothes, user By using preset control in 3DS MAX, the dress ornament that user selects is replaced to pair of the pre-selected game role of user Position is answered, at this point, dress ornament has the position being overlapped with the naked mold of game role, these positions being overlapped just will include naked calligraphy or painting model body Vertex and dress ornament in same position vertex, i.e., include multiple vertex at the position of above-mentioned coincidence.In above-mentioned splicing Occur multiple vertex in, there is a kind of vertex be in the edge of dress ornament, the i.e. stitching portion of dress ornament and naked mould, these be in dress ornament and The vertex of naked mould stitching portion is the splicing vertex of above-mentioned splicing edge line, includes in multiple vertex at the position of above-mentioned coincidence, The vertex for removing splicing vertex is to be overlapped vertex.

Step S233, screening obtains being overlapped vertex from the vertex for meet preset condition, and merges vertex is overlapped.

In an alternative embodiment, still by taking above-mentioned user is previously selected game role replacement clothes as an example, when After getting the vertex for meeting preset condition, the vertex for meeting preset condition is distinguished so that distinguish be overlapped vertex and For the purpose of splicing vertex, then the coincidence vertex distinguished in result is merged.

In the above-described embodiments, it should be noted that exist in the purpose merged to the coincidence vertex distinguished in result In reducing the redundancy vertex in game role, so that amount of compressed data is so that game is more smooth.It is merged in opposite vertexes When should be noted that the vertex of merging is more, the smooth degree of game is better, but therewith the careful degree of picture then can under Drop.

In a kind of optionally example, still by taking above-mentioned family is previously selected game role replacement clothes as an example, when weight When closing vertex including 100000 vertex, if 100000 vertex, which are merged, becomes 20000 vertex, the size of game role is obtained Compression is arrived, but the fine degree of game role has been similarly obtained compression, if 100000 vertex, which are merged, becomes 40000 tops Point, the size of game role is greater than role's size when being compressed to 10000 vertex, but the careful degree of thin game role at this time Greater than careful degree when being compressed to 10000 vertex.Therefore when opposite vertexes merge, removing meets the big of game role Small degree is still to take into account the careful degree of game role.The number of new summit is specifically incorporated into the vertex of target object, by swimming The property and player experience of opera script body determine.

Herein it should be noted that in the above-mentioned vertex for meeting preset condition, preset condition is can arbitrarily to obtain entirely The condition on the vertex being overlapped after portion's splicing.

From the foregoing, it will be observed that scheme provided by the above embodiments of the present application, obtains the vertex for meeting preset condition, wherein full The vertex of sufficient preset condition includes the coincidence vertex of overlapping position and splicing edge line after two target objects to be spliced splice Splice vertex, screening obtains being overlapped vertex from the vertex for meet preset condition, and merges vertex is overlapped.Above scheme By way of distinguishing and being overlapped vertex and edge vertices, the technical effect only merged to coincidence vertex is realized.

In a kind of optinal plan that the above embodiments of the present application provide, above-mentioned steps S233, from the top for meeting preset condition The step of being screened in point before obtaining being overlapped vertex further include:

Step S2331 adjusts the normal direction for splicing vertex to preset direction.

In an alternative embodiment, Fig. 3 is united according to the vertex of target object to be spliced in the embodiment of the present application 1 Schematic diagram before one normal direction, as shown in connection with fig. 3, figure middle conductor crosspoint are used to characterize the top of target object to be spliced Point, what apex extended out is not belonging to the line segment of plane locating for vertex for characterizing the normal direction on the vertex.In conjunction with Fig. 3 It is found that adjusting by the normal direction for splicing vertex to before preset direction, same position has multiple normal directions different Vertex, Fig. 4 is the schematic diagram unified after normal direction according to the vertex of target object to be spliced in the embodiment of the present application 1, As shown in connection with fig. 4, the result to preset direction is adjusted using the normal direction on preset control adjustment splicing vertex in 3DS MAX For shown in Fig. 4, the normal direction on multiple vertex of same position is all the same.

Herein it should be noted that adjusting by the normal direction for splicing vertex to during the realization of preset direction, on It states preset direction and acquisition is calculated according to the TBN information on multiple vertex of same position by 3DS MAX.

Step S2333, to splicing apex marker vertex color.

It in an alternative embodiment, can be black by splicing apex marker.

Herein it should be noted that when for splicing apex marker vertex color, the vertex color of label can be compiled for any 3D Volume discernmible color of software, and the unlimited black with above-described embodiment.

Redundancy vertex is merged it should also be noted that, the purpose for splicing apex marker vertex color is to work as herein When, it is overlapped vertex from all meeting to filter out in the vertex of preset condition, the vertex of vertex color is as marked, it is possible thereby to know Dawn, the purpose of above scheme are the coincidence vertex distinguished meet in whole vertex of preset condition and splicing vertex, therefore, this Application above-mentioned steps are unlimited and are splicing apex marker vertex color, and can distinguish the equal energy of scheme for being overlapped vertex with splicing vertex It is enough in the application.

From the foregoing, it will be observed that the normal direction for splicing vertex is adjusted to default in the scheme that the above embodiments of the present application propose Direction, and to splicing apex marker vertex color.Above scheme is made by adjusting the normal direction for splicing vertex to preset direction The TBN information for obtaining the vertex of the edge in target object to be spliced can be unified, to produce after having reached elimination splicing The technical purpose of raw flaw, above scheme to splicing apex marker vertex color so that 3D software for editing to redundancy vertex into The technical purpose distinguished when row merging and be overlapped vertex and splicing vertex, and only coincidence vertex is merged.Therefore, above scheme Not only make the tangent line space vector on the splicing vertex of target object to be spliced unified, and distinguishes the coincidence top of target object Point and splicing vertex, thus reached during removing redundancy vertex, the technical effect that only coincidence vertex is merged, When further solving any two target object for including in the stereo-picture of the prior art and spliced, when due to merging The tangent line space vector of opposite vertexes is recalculated so that splicing edge tangent line space vector and master tangent space to Measure it is inconsistent, so as to cause stitching portion generate flaw the technical issues of.

In a kind of optinal plan that the above embodiments of the present application provide, above-mentioned steps S233, from the top for meeting preset condition Screening obtains being overlapped vertex in point, and will be overlapped vertex and merge and include the following steps:

Step S2335 filters out the vertex of unmarked vertex color from the vertex for meet preset condition, confirms unmarked top The vertex of point color is to be overlapped vertex.

Step S2337 will confirm that be overlapped the vertex on vertex and merging.

In an alternative embodiment, by taking above-mentioned user is previously selected game role replacement clothes as an example, right Splice the vertex color of apex marker when acquiring the whole vertex for meeting preset condition, to traverse all full for black The vertex of sufficient preset condition, and confirm that the vertex of unmarked vertex color is coincidence vertex to be combined.

Herein it should be noted that when handling game role or stereo-picture, may due to a variety of demands, Vertex color is marked in opposite vertexes, so if the vertex of included label vertex color in vertex, then to splicing apex marker When the color of vertex, need to make with labeled vertex color to distinguish.

From the foregoing, it will be observed that being filtered out not from the vertex for meet preset condition in the scheme that the above embodiments of the present application propose The vertex for marking vertex color confirms the vertex of unmarked vertex color to be overlapped vertex, will confirm that be overlapped the vertex on vertex and carrying out Merge.Above scheme has reached the technical effect that the screening in the whole vertex for meeting preset condition is overlapped vertex, and to coincidence Vertex merges, and has reached the technical purpose for eliminating the redundancy vertex that the splicing of target object generates in stereo-picture.

In a kind of optinal plan that the above embodiments of the present application provide, above-mentioned steps S2337 be will confirm that be overlapped vertex Vertex merges, comprising:

Step S23371 obtains the vertex information on the coincidence vertex of any two target object to be spliced, wherein vertex Information includes: the Texture Coordinates and tangent line space vector on vertex.

Step S23373 screens Texture Coordinates phase in the vertex of any two target object overlapping position to be spliced Same the first vertex and the second vertex.

Step S23375, by the tangent line space vector on the first vertex and the second vertex be calculated new tangent line space to Amount.

Step S23377, by the common Texture Coordinates in the first vertex and the second vertex and new tangent line space to Amount determines the vertex data for merging obtained new summit.

In an alternative embodiment, it is calculated by the tangent line space vector on the first vertex and the second vertex new Tangent line space vector can be obtained by following code:

From the foregoing, it will be observed that obtaining any two target object to be spliced in the scheme that the above embodiments of the present application propose It is overlapped the vertex information on vertex, wherein vertex information includes: the Texture Coordinates and tangent line space vector on vertex, any Identical first vertex of Texture Coordinates and the second vertex are screened in the vertex of two target object overlapping positions to be spliced, are led to New tangent line space vector is calculated in the tangent line space vector for crossing the first vertex and the second vertex, passes through the first vertex and second The common Texture Coordinates in vertex and new tangent line space vector determine the vertex data for merging obtained new summit.It is above-mentioned Step calculates the top of new summit after merging by the vertex information on the coincidence vertex of acquisition any two target object to be spliced Point data realizes the technical effect for merging vertex, and then has reached the technical purpose of removal redundancy vertex.

In a kind of optinal plan that the above embodiments of the present application provide, preset condition is in two target objects to be spliced Whole vertex in, have vertex identical with the Texture Coordinates on vertex.

In an alternative embodiment, as shown in connection with fig. 3, the vertex shown in Fig. 3 with multiple normal directions is For multiple vertex for meeting preset condition.

Herein it should be noted that the vertex for meeting preset condition is the vertex with same position, due to vertex Location information has corresponding relationship with the normal map coordinate on vertex, therefore works as the location information phase on two or more vertex Meanwhile inevitable normal map coordinate having the same, therefore, when acquisition meets the vertex of preset condition, vertex is in same method With the identical vertex in vertex or position of same coordinate value in line mapping coordinates, above-mentioned two conditions be it is of equal value, can be with Any one condition obtains the vertex for meeting preset condition as preset condition.

From the foregoing, it will be observed that preset condition is in two targets pair to be spliced in the scheme that the above embodiments of the present application propose In whole vertex of elephant, there is vertex identical with the Texture Coordinates on vertex, realize the skill for obtaining vertex to be combined Art purpose.

In a kind of optinal plan that the above embodiments of the present application provide, above-mentioned steps S25, by the tangent line on multiple splicing vertex Space vector, which is adjusted to identical, to be included the following steps:

Step S251, the angle adjusted between the corresponding extended line of multiple location points is less than predetermined angle, so that multiple The tangent line space vector for splicing vertex is identical, wherein location point is splicing vertex corresponding point in Texture Coordinates.

In above-mentioned steps, Fig. 5 is according to being adjusted between the corresponding extended line of multiple location points in the embodiment of the present application 1 Angle is less than the schematic diagram of predetermined angle, and as shown in connection with fig. 5, the intersection point of edge and other line segments is location point, position in figure The direction that the direction of the corresponding extended line of point is point A Zhi point B as shown in Figure 5, the direction of the extended line of multiple location points such as Fig. 5 In arrow shown in.
