When generating three-dimensional virtual scene data, a creator of a scene generally performs manual creation, and the creation methods used by different creators are different. However, in the process of manually creating the three-dimensional virtual scene, the generation efficiency of the three-dimensional virtual scene is reduced due to complicated creation steps, a large amount of human resources are consumed, the generation time of the three-dimensional virtual scene is greatly wasted, and the generated three-dimensional virtual scene cannot be directly represented as an image with a material effect finally, so that the generation efficiency of the three-dimensional virtual scene data is influenced. An embodiment of the present invention provides a method for generating three-dimensional virtual scene data, as shown in fig. 1, the method includes:
101. and acquiring geometric model data and model layout parameters of a basic component model of the virtual scene to be built.

The basic component model is a basic building block unit for building a three-dimensional virtual scene, the basic component model is a non-static model, and the three-dimensional modeling coordinates of the basic component model can be adjusted to obtain UV with different shapes, namely, the UV coordinates of the three-dimensional modeling textures with different shapes are represented. Meanwhile, the basic component models are spliced with each other by configuring a splicing interface, for example, the square component models and the cone component models are spliced with each other, and the basic component models include but are not limited to models in basic set shapes such as box bodies, cones, cylinders, pyramid bodies, spheres, bent connecting pieces, linear connecting pieces, spiral connecting pieces and the like. Specifically, the basic component model is used for representing several most basic model bodies expected to build the virtual scene, and at the moment, geometric model data and model layout parameters are used as basic parameters for building the basic component model. The geometric model data are used for representing the geometric shape of the basic component model in a three-dimensional space, the model layout parameters are used for representing the distribution position and the logical relationship of the basic component model, the distribution position is the composition position of the basic component model expected to be built in the three-dimensional virtual scene, and the logical relationship is the logical relationship of Boolean operation between the basic component models, such as logic and, logic or, logic not, and logic XOR, so that the current execution main body automatically builds the scene model in the three-dimensional virtual scene based on the geometric model data and the model layout parameters.
It should be noted that the geometric model data and the model layout parameters of the basic component model of the virtual scene to be built can be input in real time by a scene editor or directly stored in the current execution end, so as to be acquired when the basic component model needs to be built, and the embodiment of the present invention is not particularly limited.
102. And determining the construction parameters of the basic component model according to the geometric model data and the model layout parameters, and generating a target scene model matched with the construction parameters.
In the embodiment of the invention, after the geometric model data and the model layout parameters are obtained, the construction parameters of the basic component model are determined in a calculation mode, and at the moment, the construction parameters are used for representing the specific spatial position, the model parameters and the like of the basic component model constructed in the three-dimensional virtual model. The obtained basic component models can be multiple, each basic component model can be spliced through a splicing interface, the geometric shape of each model is determined based on geometric model data, the spatial position of each basic component model in a three-dimensional space is determined based on the distribution position in the model layout parameters, at the moment, the splicing positions of the basic component models are calculated according to the logic relation in the model layout parameters of each basic component model aiming at the splicing among the multiple basic component models, so that the spatial positions, the model parameters and the like of the spliced basic component models are obtained and serve as setting parameters, and the target scene model of the basic component model is set up in the three-dimensional virtual scene. For example, as shown in fig. 2, the basic component model includes a cube, a bridge, a cuboid, and the like, and spatial positions and model parameters of the cube, the bridge, and the cuboid in the virtual street view are calculated based on geometric model data and model layout parameters of the cube, the bridge, and the cuboid, so as to generate a target street view model, at this time, the target street view model includes a plurality of building models in the virtual scene, and each building model is a model of a simple geometric body, so as to further refine the model.
103. And obtaining model adjusting parameters of the target scene model, and adjusting the construction parameters of the target scene model through the model adjusting parameters to obtain an adjusted target scene model.
In the embodiment of the invention, as the basic component model is a three-dimensional model with different geometric shapes, in order to realize convenient adjustment of the composition of the target scene and further improve the refinement degree of the composition, the model adjustment parameters of the target scene model are firstly obtained. The target scene model may include one basic component model built in the three-dimensional virtual scene, or may include a plurality of basic component models built in the three-dimensional virtual scene, and at this time, the model adjustment parameters for obtaining one or more target scene models may be input by a user, or may also be model adjustment parameters for establishing a matching relationship with the target scene model in advance, so as to achieve the purpose of automatic adjustment. At this time, since the target scene model is generated based on the set-up parameters, and the corresponding model adjustment parameters for adjusting the target scene model are the data content for adjusting the set-up parameters, the set-up parameters are adjusted by the model adjustment parameters, so as to realize a refined composition of the target scene model, as shown in fig. 3.
104. And obtaining a map material matched with the target scene model, rendering the target scene model based on the map material, and generating three-dimensional virtual scene data.
In the embodiment of the invention, in order to show the composition effect of the virtual scene, the material effect is increased, the chartlet material matched with the target scene model is obtained, and the chartlet material is used for rendering the target scene model, so that the material effect is added to the target scene model in the virtual scene, and different scene effects are realized. The chartlet material may be generated by baking in advance, or may be loaded from a cloud or a local material database, and the embodiment of the present invention is not limited specifically. In addition, when the target scene model is rendered based on the map material, the rendering is performed directly based on the map material matched with the target scene model, and three-dimensional virtual scene data including all rendered target scene models is obtained, as shown in fig. 4.
Since the three-dimensional virtual scene data is three-dimensional and can be used as a data base for creating a virtual scene such as a three-dimensional animation or a game for a scene editor, the three-dimensional virtual scene data can be directly imported to a game engine or an action creation system for use by rendering based on a game engine, an animation creation system, or the like in the current execution side.
In another embodiment of the present invention, for further definition and explanation, as shown in fig. 5, the step 102 of generating a target scene model matching the set-up parameters includes:
201. calling a space partition component, and building the basic component model in a three-dimensional virtual scene based on the space partition component;
202. and configuring the initial construction parameters into the construction parameters through the space partition assembly to obtain a target scene model in the three-dimensional virtual scene.
In the embodiment of the present invention, the spatial partition component may be a component that is embedded in a game engine and adds a basic component model to a virtual scene, and the current execution subject calls the spatial partition component through the game engine to construct the basic component models with different geometric shapes. The space partition component is provided with a plurality of basic component models in different shapes as basic building block units, so that the building is carried out in a three-dimensional virtual scene. Meanwhile, initial setting parameters of different basic component models are configured in the space partition component, when the basic component model is set up based on the space partition component, setting is carried out according to the initial setting parameters, and then setting is carried out on time initially according to setting parameter configuration obtained through calculation based on geometric model data and model layout parameters, so that a target scene model is obtained.
It should be noted that the generation of the game three-dimensional virtual scene in the embodiment of the present invention is applied to a game engine scene building function, and the game engine may be UE, Unity, or the like, which is not particularly limited. And then, according to the building parameters obtained by calculating the geometric model data and the model layout parameters, calling the space partition component in the game engine to build the basic component model to obtain the target scene model. At this time, in the game engine, the target scene model built according to the building parameters is a three-dimensional model with a spatial position, a spatial layout and a splicing relation, and the target scene model is directly built and generated according to the building parameters.
In another embodiment of the present invention, for further limitation and description, as shown in fig. 6, step 103 obtains a model adjustment parameter of the target scene model, and adjusts a building parameter of the target scene model according to the model adjustment parameter, so as to obtain an adjusted target scene model, where the obtaining includes:
301. acquiring scene adjustment operation on the target scene model;
302. analyzing the adjustment content generated by the scene adjustment operation on the target scene model, determining model adjustment parameters, and adjusting the construction parameters of the target scene model according to the model adjustment parameters based on the space editing subassembly of the space partition assembly to obtain an adjusted target scene model.
In order to realize flexible adjustment of model composition so as to meet composition requirements of different scene editors, parameters of a target scene model are adjusted based on model adjustment parameters, and thus, the detailed adjustment of a target scene is realized. Specifically, in the process of composition making of the virtual scene, scene adjustment operation of the target scene model is obtained, the scene adjustment operation includes operation content for adjusting geometric model data and model layout parameters of the target scene model, so that model adjustment parameters are determined based on the scene adjustment operation, and the purpose of performing detailed adjustment on the target scene model according to the model adjustment parameters is achieved. The scene adjusting operation comprises adjusting contents of model points, model lines and model surfaces of the target scene model, so that the operation contents of adjusting the geometric model data and the model layout parameters are determined based on the operation contents, including but not limited to moving the target scene model points, extending the target scene model lines, expanding the target scene model surfaces, splicing a plurality of target scene models, moving the spatial positions and the like. At this time, if the point, the line, or the plane corresponding to the adjustment operation is determined, the target scene model may be determined correspondingly, and the embodiment of the present invention is not particularly limited. In addition, the target scene model surface is composed of target scene model point connecting lines, and the connecting lines between the target scene model points comprise target scene model lines, so that the linkage adjustment of other target scene model points, target scene model lines and target scene model surfaces can be realized for any adjustment content of the target scene model points, the target scene model lines and the target scene model surfaces.
It should be noted that, the scene adjustment operation includes operation contents for adjusting geometric model data and model layout parameters of the target scene model, including adjustment operations for adjusting positions, lengths, sizes, and the like of target scene model points of the target scene model, at this time, the adjustment operations determine change contents of the geometric model data and the model layout parameters, and determine the change contents as model adjustment parameters, and the building parameters of the target scene model are adjusted according to the model adjustment parameters based on the spatial editing subassembly of the spatial partitioning component, so as to obtain the adjusted target scene model. The embodiment of the present invention is not particularly limited. The space partition component is embedded into the game engine, and after the target scene model is built, the editing subassembly in the space partition space is called, so that the building parameters of the target scene model are refined and adjusted according to the model adjusting parameters based on the space editing subassembly, the target scene model after the model parameters are adjusted is obtained, and at the moment, the target scene model is a three-dimensional model with rich scene details.
In another embodiment of the present invention, for further definition and explanation, as shown in fig. 7, before the step 104 of obtaining a map material matching the target scene model, the method further includes:
401. loading resource maps for rendering different target scene models;
402. creating a material ball based on the resource map, and configuring at least one material parameter for the material ball to obtain a map material;
403. and configuring matched parameter nodes for the material parameters.
In order to construct three-dimensional virtual scene data of a rendering map material, the composition effect of a virtual scene is improved, and the map material is baked in advance. The resource map is pre-stored in a material library, so that when the map material is constructed, the resource map is loaded from the material library, at this time, the material library can be a Quixel or a certain accelerator material library, the resource map is a material texture map used for rendering different composition models, and the map material is generated based on the resource map. Specifically, after the resource map is loaded, a material ball matching the resource map is created, as shown in fig. 8, and material parameters are configured for each material ball, so that the material is adjusted based on the material parameters, and the material parameters include, but are not limited to, color, transparency, and the like, so that the scene of the rendering model is adjusted.
It should be noted that, in order to adjust the map material based on the material parameter, so as to satisfy the composition effect for different virtual scenes, after the map material is generated, parameter nodes are configured for each material parameter of the map material, so as to adjust the material parameter based on the parameter nodes. The parameter node is a node bound to different material parameters in the map material, and the material is adjusted according to the parameter of the node, so that after the map material is generated, the material parameter of the map material is adjusted based on the parameter node, for example, the color or transparency of the wall material is adjusted, and the embodiment of the invention is not particularly limited.

In order to simplify a selection process of a mapping material during rendering of three-dimensional virtual scene data and achieve the purpose of automatically generating the three-dimensional virtual scene data, specifically, the mapping material matched with each model surface of a target scene model is determined according to a mapping material corresponding relation, the mapping material corresponding relation is used for representing the corresponding relation between different target scene model surfaces and different material mappings, and the mapping material matched with the model surface of the target scene model is determined by pre-configuring a current execution end and calling the mapping material corresponding relation when rendering is needed. The composition material corresponding relationship may be written in advance by a user, or may be downloaded simultaneously when the resource map is loaded, and the embodiment of the present invention is not particularly limited. After the chartlet material is determined, a material ball of the configured chartlet material is called, so that the model surface of the target scene model is rendered according to the material parameters corresponding to the material ball to obtain three-dimensional virtual scene data, and at this time, the three-dimensional virtual scene data can be directly realized through a rendering module in a game engine, as shown in fig. 4, and the embodiment of the invention is not particularly limited.
In another embodiment of the present invention, for further limitation and explanation, as shown in fig. 9, after obtaining a mapping material matched with the target scene model in step 104, rendering the target scene model based on the mapping material, and generating three-dimensional virtual scene data, the method further includes:
501. acquiring at least one scene atmosphere model;
502. rendering the scene atmosphere model into the three-dimensional virtual scene data according to the scene characteristic auxiliary relationship to obtain the scene three-dimensional virtual scene data.
As the three-dimensional virtual scene data is a three-dimensional virtual scene, in order to increase more scene effects, after the three-dimensional virtual scene data is obtained through rendering, the scene atmosphere model is obtained, and the scene atmosphere model is rendered into the three-dimensional virtual scene data according to the scene characteristic auxiliary relationship, so that the scene three-dimensional virtual scene data with the scene atmosphere sense is obtained. The scene atmosphere model is a model for increasing atmosphere characteristics of the three-dimensional virtual scene data, and the atmosphere characteristics include, but are not limited to, contents such as special effects, plants, celestial bodies and the like for representing the scene atmosphere in the three-dimensional virtual scene data, for example, as shown in fig. 10, so that the detailed atmosphere effect of the three-dimensional virtual scene data is embodied. In addition, in order to automatically realize the rendering of the atmosphere sense, the scene atmosphere model is rendered into the three-dimensional virtual scene data according to the scene characteristic auxiliary relationship, and the scene characteristic auxiliary relationship is used for representing the characteristic relationship between different scene atmosphere models and different target scene models in the three-dimensional virtual scene data, for example, a leaf model serving as the scene atmosphere model has an attachment relationship with a wall target scene model, so that the leaf model is rendered by attaching to the wall model during rendering. Specifically, the characteristic relationship may include, but is not limited to, an attachment relationship, a positional relationship, an embedding relationship, and the like, so that when rendering is performed, the ambience is increased by adding the scene atmosphere model, so as to obtain three-dimensional virtual scene data with the ambience, and achieve the purpose of generating accurate and refined virtual scene data.
In another embodiment of the present invention, for further definition and illustration, the method further comprises:

602. and acquiring process information matched with a target rollback node from rollback information obtained by starting the rollback mechanism so as to adjust data in the process information.
In the embodiment of the invention, when the three-dimensional virtual scene is built, for the generation of the target scene model, Boolean logic calculation is needed to be based on, so that different basic component models are spliced or the target scene model is adjusted and refined, and a rollback mechanism is configured to improve the efficiency and flexibility of building the three-dimensional virtual scene. At the moment, starting a rollback mechanism from the acquisition of geometric model data and model layout parameters of a basic component model of the virtual scene to be built so as to generate three-dimensional virtual scene data, so as to backtrack any rollback node in the generated three-dimensional virtual scene data. The rollback mechanism is used for tracking and recording process information for generating the three-dimensional virtual scene data, wherein the process information is information in the whole process from the acquisition of geometric model data and model layout parameters of a basic component model to the generation of the three-dimensional scene data, and at the moment, the process information comprises but is not limited to blank virtual scene data, operation contents for adjusting the geometric model data and the model layout parameters, a target scene model for operation adjustment and various operation time points, so that the rollback purpose is achieved through recording and tracking the process information. After a rollback mechanism is started, when the generation of the three-dimensional virtual scene data in the embodiment of the invention is executed currently, each operation time sequence and corresponding operation content are recorded and tracked, and a rollback node corresponding to each operation and corresponding recorded process information are determined, so that when a rollback operation is performed, a target rollback node is determined from rollback information including all process information, and corresponding process information is obtained and output. The rollback operation is to select a target rollback node from the process information corresponding to the recording operation time sequence after completing recording and tracking of the process information, and if the target rollback node is selected according to a time point, the target rollback node may also be quickly returned to a previous operation recording point in a mouse wheel manner, so as to call the recording information at the previous recording point for display. The rollback information comprises a piece of process information corresponding to each recording time point, and each recording time node corresponds to a rollback node so as to select a target rollback node from the rollback nodes.
It should be noted that, because the rollback mechanism is used to record and track process information at any time point in the whole process of obtaining geometric model data and model layout parameters of the basic component model of the virtual scene to be built to generate three-dimensional virtual scene data, the output of the recorded information may be virtual scene rendering according to blank virtual scene data at each time point, or operation content for adjusting the geometric model data and the model layout parameters, or a target scene model for performing operation adjustment, that is, re-rendering a virtual scene at a target rollback node, thereby overcoming the disadvantage of boolean computation destructiveness. Of course, if the process information corresponding to the rollback operation only includes the adjustment of the coordinates of the model points, the corresponding adjustment content may be directly output, and if the process information includes the content of the boolean operation in the logical relationship, the virtual scene needs to be rendered again.

It should be noted that, in the process of building a basic component model based on a space partition component, a basic component model of a simple geometric shape matched with a scene in reference composition image data is built by using the space partition component according to the reference composition image data, at this time, a scene editor can select a matched geometric shape from the space partition component according to the scene in the reference composition image data to build the basic component model, and the space partition component can also scan or image recognize two-dimensional reference composition image data to determine the spatial position and layout composition of a key geometric body in the scene, so as to obtain geometric model data and model layout parameters of the basic component model of a virtual scene to be built, so as to calculate the parameters and build the basic component model. Meanwhile, in order to refine the basic component model in the shape of a simple geometric figure and simplify the operation flow of a user, the setting parameters of the basic component model can be refined and adjusted by using the input basic composition requirement data, and the embodiment of the invention is not particularly limited.

Further, scene three-dimensional virtual scene data with more ambience is obtained by rendering the scene atmosphere model. At this time, since all the generated three-dimensional virtual scenes can be realized by the game engine UE4, the three-dimensional virtual scenes can be converted into the static mesh-to-FBX file format and imported into the 3D software at the time of post-production, as shown in fig. 11.
