In the drawings, like reference numbers indicate identical or functionally similar elements. Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
In addition, numerous specific details are set forth in the following detailed description in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements, and circuits well known to those skilled in the art have not been described in detail in order not to obscure the present disclosure.
Fig. 1 shows a flowchart of a temporary building model generation method according to an embodiment of the present disclosure. As shown in fig. 1, the method includes: step S100, the created temporary building area and the model to be generated in the temporary building area are obtained. Here, the temporary building area refers to an area occupied by the temporary building model. The region may be rectangular, or may be circular or the like. In this application, in order to facilitate the subsequent calculation, the temporary building area setting may be set to be rectangular, so as to simplify the subsequent calculation process. Meanwhile, it will be understood by those skilled in the art that the number of building models included in the temporary building generated in the temporary building area is generally plural, and thus the number of models generated in the temporary building is generally two or more.
Step S200, sequentially extracting a first model and a second model from the selected models, and obtaining a first coordinate array and a second coordinate array based on the source file of the first model and the source file of the second model. The first model and the second model are any one of the acquired models. Here, it should be noted that when the first model and the second model are sequentially extracted from the acquired models, the first model and the second model may be implemented in a permutation and combination manner. That is, the acquired models are combined two by two to obtain a plurality of model groups. And then sequentially acquiring two models in each model group to serve as a first model and a second model respectively.
Such as: when the acquired models include three, the three models are M1, M2, and M3, respectively. And combining M1, M2 and M3 two by two to obtain three model groups. The three model groups obtained were: M1M2, M2M3 and M1M3. Further, the models in the three model groups are sequentially selected as a first model and a second model, respectively.
Here, it should also be noted that the resulting first coordinate array is the vertex coordinate array of the first model, and the second coordinate array is the vertex coordinate array of the second model. Since the shapes of the first model and the second model may be irregular shapes, the number of vertices of the first model and the vertices of the second model may be different according to the shapes of the models. Thus, the vertex coordinates in the first coordinate array and the vertex coordinates in the second coordinate array may be the same or different. Such as: when the first model is a cuboid, the number of coordinates in the first coordinate array is 8, and the coordinates are respectively 8 vertexes of the cuboid. When the first model is a triangular pyramid, the number of coordinates in the first coordinate array is 4.
And step S300, respectively converting the first coordinate array and the second coordinate array to obtain corresponding first projection coordinates and second projection coordinates. That is, each vertex coordinate in the first coordinate array is converted to obtain a first projection coordinate set. And simultaneously, converting each vertex coordinate in the second coordinate array to obtain a corresponding second projection coordinate set. The first projection coordinate set comprises a plurality of first projection coordinates, and the number of the first projection coordinates is the same as that of the vertex coordinates in the first coordinate set and corresponds to one of the vertex coordinates. The second projection coordinate set also includes a plurality of second projection coordinates. The number of the second projection coordinates is the same as the number of the vertex coordinates in the second coordinate array, and the second projection coordinates are in one-to-one correspondence.
And then, through step S400, sequentially traversing the projection coordinates in the first projection coordinate set and the second projection coordinate set, and obtaining the distance between each vertex of the first model and each vertex of the second model according to the projection coordinates in the first projection coordinate set and the projection coordinates in the second projection coordinate set. Finally, through step S500, when the distances between the vertices of the first model and the vertices of the second model are all greater than or equal to the preset values, the first model and the second model are automatically generated in the temporary building area according to the preset sequence, so that the purpose of automatically generating the temporary building model is achieved.
Here, the distance between each vertex of the first model and each vertex of the second model being equal to or greater than the preset value means that there is no case where the distance between each vertex of the first model and each vertex of the second model is less than the preset value.
According to the temporary building model generation method, the model which is required to be generated in the temporary building area at present is acquired, and coordinate conversion is carried out based on the acquired vertex coordinates of the first model and the acquired vertex coordinates of the second model in the model, so that a corresponding first projection coordinate set and a corresponding second projection coordinate set are obtained. And then, obtaining the distance between each vertex of the first model and each vertex of the second model through the projection coordinates in the first projection coordinate set and the projection coordinates in the second projection coordinate set, and automatically generating the first model and the second model in the temporary building area according to a preset sequence when the distance between each vertex of the first model and each vertex of the second model is larger than or equal to a preset value, so as to realize the purpose of automatically generating the temporary building model. Compared with the method that the development designer manually carries out placement of each model in the related art, the temporary building model generation method only needs to establish a corresponding temporary building area by the development designer and limit the required model, and can realize automatic generation of the temporary building model without executing other manual operations, so that the generation process of the temporary building model is effectively simplified, the generation difficulty of the temporary building model is reduced, and the generation efficiency of the temporary building model is greatly improved.
It should be noted that, the temporary building model generating method of the present application may be implemented based on the Unity development platform. That is, a corresponding model database is added to the Unity development platform, the model database having a plurality of different building models stored therein. And the model database can also update data according to actual conditions so as to ensure the comprehensiveness and diversity of model types, thereby being capable of meeting the construction and generation of various different temporary building models.
When the temporary building model generation method is executed based on the Unity development platform, when the created temporary building area is obtained, a research and development designer can directly draw the currently required area on the Unity operation interface, so that the temporary building area is created. The operation is simple and easy to realize.
Further, when the creation of the temporary building area and the selection of the model are performed based on the Unity development platform, in one possible implementation manner, the first coordinate array and the second coordinate array are obtained based on the source file of the first model and the source file of the second model respectively, which can be achieved in the following manner.
First, a source file of a first model and a source file of a second model are read. Wherein, the source file of the model stored in the database contains all data of the model, such as: vertex information, hierarchical structure, etc. And then, by calling a grid renderer component (namely, a mergence renderer) in the untiy development platform, a first coordinate array and a second coordinate array are extracted from a source file of the first model and a source file of the second model according to the grid renderer component.
That is, by calling the mergencener in the uny development platform, vertex information of the first model and vertex information of the second model are respectively extracted from the source file of the first model and the source file of the second model according to the mergencener. The component in the UNTIY development platform is directly called to extract the vertex information of the model based on the UNTIY development platform, and the development and design of information extraction are not needed to be repeated, so that the development difficulty of the temporary building model generation method is further reduced, and meanwhile, the operation process of information extraction is further simplified.
Further, after the vertex coordinates of the first model and the vertex coordinates of the second model are obtained, coordinate conversion can be performed on the first coordinate array and the second coordinate array to obtain a corresponding first projection coordinate set and a corresponding second projection coordinate set.
According to the foregoing, when the temporary building model generating method of the present application is executed based on the universal development platform, the coordinate conversion of the first coordinate array and the second coordinate array may be implemented by directly calling the local coordinate to world coordinate transformation matrix component (i.e., mesh.
That is, referring to fig. 2, firstly, through step S110, a temporary construction area is created in a three-dimensional scene of the Untiy development platform to obtain the temporary construction area, and step S120, after a model automatically generated in the temporary construction area is selected to obtain a selected model, through step S200', a first model and a second model are sequentially extracted from the selected model, and based on a source file of the first model and a source file of the second model, a first coordinate array and a second coordinate array are obtained according to a merrender, and then, through step S310, a local coordinate in the Untiy platform is called to a world coordinate transformation matrix assembly, and each coordinate in the first coordinate array and each coordinate in the second coordinate array are transformed according to the local coordinate to the world coordinate transformation matrix assembly, so as to obtain a corresponding first matrix set and a second matrix set. Then, through step S320, a product of the first matrix set and the first coordinate set is calculated to obtain a first projection coordinate set, and a product of the second matrix set and the second coordinate set is calculated to obtain a second projection coordinate set.
Here, it should be noted that, when the local coordinate to world coordinate transformation matrix component transforms each coordinate in the first coordinate array and each coordinate in the second coordinate array, the obtained first matrix set includes a plurality of matrices, and the second matrix set also includes a plurality of matrices. The first matrix group comprises a plurality of matrixes, wherein the matrixes in the first matrix group are in one-to-one correspondence with the vertex coordinates in the first coordinate array, and the matrixes in the second matrix group are in one-to-one correspondence with the vertex coordinates in the second coordinate array.
Meanwhile, it should be further noted that performing product calculation on the first matrix set and the first coordinate set to obtain a first projection coordinate set refers to performing product calculation on the matrix in the first matrix set and the vertex coordinates in the first coordinate set in a one-to-one correspondence manner. Correspondingly, performing product calculation on the second matrix set and the second coordinate set to obtain a second projection coordinate set refers to performing product calculation on each matrix in the second matrix set and each vertex coordinate in the second coordinate set in a one-to-one correspondence manner.
For example, the first coordinate array includes 5 vertex coordinates, A, B, C, D and E, respectively. Correspondingly, the first matrix group obtained when converting the coordinates of each vertex in the first coordinate array also comprises 5 matrices, which are respectively: a1, A2, A3, A4 and A5. Wherein, A1 is obtained by converting the vertex coordinate A, A2 is obtained by converting the vertex coordinate B, and so on. When the first matrix group and the first coordinate array are multiplied to obtain a first projection coordinate group, the first matrix group and the first coordinate array are multiplied to obtain a projection coordinate, the first projection coordinate group containing 5 projection coordinates is finally obtained by multiplying A1 and A to obtain a projection coordinate, multiplying A2 and B to obtain a projection coordinate, multiplying A3 and C to obtain a projection coordinate, multiplying A4 and D to obtain a projection coordinate and multiplying A5 and E to obtain a projection coordinate.
Here, it should be noted that, when the product calculation is performed on each matrix in the first matrix set and each vertex coordinate in the first coordinate array in a one-to-one correspondence manner, a left-hand multiplication calculation manner may be adopted. That is, a left-hand multiplication calculation is used in the entiy development platform. I.e. projection coordinates = matrix vertex coordinates. The product calculation of one-to-one correspondence is carried out on each matrix in the first matrix group and each vertex coordinate in the first coordinate array by calling the left-hand multiplication calculation in the unitary development platform, the calculation mode is simple and convenient, and only the corresponding calculation formula is directly called for calculation, and the development of a specific algorithm is not needed, so that the development difficulty of the generation method of the temporary building model is further reduced.
The specific process of performing the product calculation on the second matrix set and the second coordinate set to obtain the second projection coordinate set is the same as or similar to the process of performing the product calculation on the first matrix set and the first coordinate set described above, and therefore will not be illustrated herein.
After the first projection coordinate set of the first model and the second projection coordinate set of the second model are obtained in any mode, the calculation of the distance between each vertex of the first model and the distance between each vertex of the second model can be performed, so that the automatic generation of the temporary building model in the temporary building area can be performed according to the distance between the first model and the second model.
In one possible implementation manner, to further improve the accuracy of the temporary building model generating method of the present application, before sequentially traversing the projection coordinates in the first projection coordinate set and the second projection coordinate set, obtaining the distances between the vertices of the first model and the vertices of the second model according to the projection coordinates in the first projection coordinate set and the projection coordinates in the second projection coordinate set (i.e., before calculating the distances between the first model and the second model), the method further includes: and obtaining boundary coordinates of the temporary building area, determining the position relationship between the first model and the temporary building area according to the first projection coordinate set and the boundary coordinates, and determining the position relationship between the second model and the temporary building area according to the second projection coordinate set and the boundary coordinates.
Here, it should be explained that the positional relationship between the first model and the temporary building area refers to the size relationship between the first model and the temporary building area. I.e. whether the first model can be inside the critical area. Correspondingly, the positional relationship between the second model and the temporary building area refers to the size relationship between the second model and the temporary building area.
When the boundary of the first model exceeds the boundary of the temporary building area or the boundary of the second model exceeds the boundary of the temporary building area, the condition that one model exists in the first model or the second model is beyond the boundary range of the temporary building area is indicated. That is, the currently created temporary area does not hold the first model or the second model. Therefore, the calculation of the vertex distances between the subsequent models is not required. The temporary building model generation process is suspended, and indication information that the temporary building model cannot be generated in the temporary building area is directly pushed and displayed at the same time, so that research and development designers are prompted to recreate the temporary building area or to select the temporary building model again.
When the boundaries of the first model are all at the boundaries of the temporary building area and the boundaries of the second model are all at the boundaries of the temporary building area, the first model and the second model are indicated to be both in the temporary building area range, so that the step of traversing the numerical values in the first projection coordinate set and the second projection coordinate set in sequence can be directly executed, and the distance between each vertex of the first model and each vertex of the second model is obtained according to the first projection coordinate set and the second projection coordinate set.
After the first projection coordinate set of the first model and the second projection coordinate set of the second model are obtained, before the distance between the vertexes of the first model and the second model is calculated, the position relation between the first model and the temporary building area and the position relation between the second model and the temporary building area are respectively determined according to the first projection coordinate set and the boundary coordinates of the first model and the second projection coordinate set and the boundary coordinates of the second model. And when the first model and the second model are determined to be in the temporary building area, calculating the distance between the vertexes of the first model and the second model. This also effectively avoids unnecessary computation processes, thereby saving resources and reducing power consumption.
The method can be realized in the following manner when determining the position relationship between the first model and the temporary building area according to the first projection coordinate set and the boundary coordinates and when determining the position relationship between the second model and the temporary building area according to the second projection coordinate set and the boundary coordinates.
Referring to fig. 2, after the projection coordinates of each model are obtained in step S320, the vertical points of each model from the boundary may be obtained by vector cross-multiplication in step S004. It should be noted here that the vertical point of each model from the boundary refers to the vertical point of each model from the boundary of the critical area.
That is, vector cross multiplication is performed on each projection coordinate in the first projection coordinate set to obtain a vertical point of the first model from the boundary of the temporary building area, so as to determine the position relationship between the first model and the temporary building area. And carrying out vector cross multiplication on each projection coordinate in the second projection coordinate set to obtain a vertical point of the second model from the boundary of the temporary building area so as to determine the position relationship between the second model and the temporary building area.
Here, it will be understood by those skilled in the art that the resulting vertical points of the first model from the boundary include a plurality of vertical points, each corresponding to a different boundary of the first model. And, the respective boundaries of the first model may be determined by coordinates of every adjacent two vertices. Meanwhile, vector cross-multiplication is a conventional technical means in the art. The vector cross equation is: u x v= { u2v3-v2u3, u3v1-v3u1, u1v2-u2v1}. Where u and v are vectors, u= (u 1, u2, u 3); v= (v 1, v2, v 3).
Based on the vector cross multiplication formula, carrying out vector cross multiplication on each projection coordinate in a first projection coordinate set of a first model to obtain a vertical point of the first model from the boundary of the temporary building area, carrying out vector cross multiplication on each projection coordinate in a second projection coordinate set of a second model to obtain a vertical point of the second model from the boundary of the temporary building area, further determining whether the first model crosses the boundary of the temporary building area according to the obtained vertical point of the first model from the boundary, and determining whether the second model crosses the boundary of the temporary building area through determining the vertical point of the second model from the boundary of the temporary building area, so that the generated temporary building model can be located in the temporary building area when automatic generation of the temporary building model in the temporary building area is carried out later.
In addition, it should be noted that after the first model and the second model are determined to be both capable of being located in the temporary building area through the steps, the distance between each vertex of the first model and each vertex of the second model can be calculated, and then the temporary building model generating process is performed according to the calculated distance between the first model and the second model.
In one possible implementation manner, when the distance between each vertex of the first model and each vertex of the second model is calculated according to the projection coordinates in the first projection coordinate set and the projection coordinates in the second projection coordinate set, the calculation of the distance between the vertex of the first model and the vertex of the second model may be performed by directly traversing the projection coordinates in the first projection coordinate set and the second projection coordinate set in sequence and using a two-point distance formula.
For example, the first projection coordinate set includes 5 projection coordinates, which are respectively: TY1, TY2, TY3, TY4 and TY5, the second projection coordinates comprise 6 projection coordinates, respectively: ty1, ty2, ty3, ty4, ty5, and ty6.
When traversing each projection coordinate in the first projection coordinate set and each projection coordinate in the second projection coordinate set in turn, the projection coordinate TY1 in the first projection coordinate set and the projection coordinate TY1 in the second projection coordinate set can be selected first, and then the distance between TY1 and TY1 is calculated by using a two-point distance calculation formula, so as to obtain the distance between the first vertex in the first model and the first vertex in the second model: TY1TY1.
Then, a projection coordinate TY2 in the first projection coordinate set and a projection coordinate TY1 in the second projection coordinate set are selected, and then a distance between TY2 and TY1 is calculated by using a two-point distance calculation formula, so that a distance between a second vertex in the first model and a first vertex in the second model is obtained: TY2TY1.
Then, a projection coordinate TY3 in the first projection coordinate set and a projection coordinate TY1 in the second projection coordinate set are selected, and then a distance between TY3 and TY1 is calculated by using a two-point distance calculation formula, so that a distance between a third vertex in the first model and a first vertex in the second model is obtained: TY3TY1.
Similarly, the distances between the vertex of the first model and the vertex of the second model are 30, which are respectively: TY1, TY1TY2, TY1TY3, TY1TY4, TY1TY5, TY1TY6, TY2TY1, TY2, TY2TY3, TY2TY4, TY2TY5, TY2TY6, TY3TY1, TY3TY2, TY3, TY3TY4, TY3TY5, TY3TY6, … …. No further examples are given here.
After the distance between the vertex of the first model and the vertex of the second model is calculated, the distance between the vertex of the first model and the vertex of the second model can be compared with a preset value for judgment. When the distance between the vertex of the first model and the vertex of the second model is not smaller than the preset value, that is, when the distance between the vertex of the first model and the vertex of the second model is larger than or equal to the preset value, the corresponding first model and the second model can be automatically generated in the adjacent building area directly according to the preset sequence. Here, it should be noted that the preset sequence refers to the placement sequence of each model in the temporary building area. Such as: the first model and the second model are placed in the adjacent building area in sequence.
The preset sequence may be determined according to a selection sequence of the model. That is, when the models to be generated in the temporary building area are selected, the selection sequence of each model also determines the placement sequence of each model in the temporary building area. In addition, the preset sequence can be determined by setting sequence labels on the selected models and then according to the set sequence labels. When the sequence tags are set for the respective models, the sequence tags may be set in advance when the models are stored in the model database.
When the distance between the vertex of the first model and the vertex of the second model is smaller than a preset value, the fact that the first model and the second model cannot be automatically generated in the temporary building area is indicated at the moment, and therefore prompt information that the temporary building model cannot be generated in the temporary building area can be directly pushed and displayed, and the fact that the currently selected model of the research and development designer is not matched with the temporary building area is prompted.
Here, it should be noted that the preset value may be set by itself according to the actual situation. The preset value is in meters, and can be set by research and development designers according to actual conditions. It is pointed out that the preset value is used to represent the shortest distance between each selected model and the boundary, and the shortest distance between each model. The preset number is set to be what is the minimum distance judged when the temporary building model is generated. In the temporary building model generation method of the present application, the value of the preset numerical value may be set to 1. By setting the value of the preset numerical value to 1, the reliability and the accuracy of the temporary building model generation method are further improved.
Further, in order to further improve the accuracy and reliability of the temporary building model generating method of the present application, in step S400, the distance between each vertex of the first model and each vertex of the second model is obtained according to the projection coordinates in the first projection coordinate set and the projection coordinates in the second projection coordinate set, and the distance between the first model and the boundary of the adjacent building area and the distance between the second model and the boundary of the adjacent building area are obtained according to the projection coordinates in the first projection coordinate set and the boundary coordinates of the adjacent building area and the projection coordinates in the second projection coordinate set. Correspondingly, when comparing each distance with the preset value, the method further comprises the step of comparing the distance between the first model and the boundary of the temporary building area with the preset value and the step of comparing the distance between the second model and the boundary of the temporary building area with the preset value.
That is, referring to fig. 2, in one possible implementation manner, the method further includes step S400', where the obtained first projection coordinate set, the second projection coordinate set, and the boundary coordinates of the temporary building area are respectively traversed in a circulating manner, and the distances between the vertices of the first model and the vertices of the second model, and the distances between the first model and the boundary of the temporary building area and the distances between the second model and the boundary of the temporary building area are calculated by using a two-point distance formula.
Further, in step S510, all the obtained distances are compared with a preset value (the preset value may be 1). And when all the distances are larger than or equal to the preset value, executing step S520, and automatically generating a first model and a second model in the temporary building area according to the preset sequence to construct and obtain a temporary building model. And when the fact that the distances are smaller than the preset value is compared, returning to the step S110 and the step S120, and pushing and displaying related prompt information.
It should be noted that, although the temporary building model generation method of the present application is described taking fig. 2 as an example, those skilled in the art can understand that the present disclosure should not be limited thereto. In fact, the user can flexibly set the execution sequence of each step and the specific implementation mode of each step according to personal preference and/or practical application scene, so long as the purpose of automatically generating the temporary building model can be achieved.
In addition, since the number of models generated in the temporary building area is generally plural, the calculation of the distance between the models may be performed in a multi-threaded manner to increase the rate of generating the temporary building model.
That is, when the first model and the second model are selected from the selected models, the selected models are combined in pairs to obtain model groups, and then the models in each model group are used as the first model and the second model respectively, and then the processes of coordinate conversion and calculation on the first model and the second model in each model group can be executed in parallel in a multithreading manner, so that the selected models can be completely generated in the temporary building area.
Correspondingly, based on the same inventive concept, the application also provides a temporary building model generating device. Since the working principle of the temporary building model generating device provided by the application is the same as or similar to that of the temporary building model generating method, the repetition is not repeated.
