[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Current game scenes are very diverse. To enhance the scene effects, game scenes typically include architectural scenes, natural scenes, and various indoor scenes. In related technologies, the models needed for the game scene are usually created first, and then different scenes are rendered based on these models using specific software. Developers often need to process the models using different methods for different types of scenes, including manually assembling models, manually drawing different models, and achieving various display effects. A complete game scene usually includes many different types of scenes, and each type of scene contains a large number of models. Manually processing these is very time-consuming and labor-intensive, prone to errors, affecting the scene effects, and reducing production efficiency. Therefore, this invention provides a method, apparatus, electronic device, and storage medium for generating virtual scenes, which can be applied to devices such as laptops and computers.

[0036] To facilitate understanding of this embodiment, a method for generating a virtual scene disclosed in this invention will first be described in detail, such as... Figure 1 As shown, the method includes the following steps:

[0037] Step S102: Obtain a pre-generated virtual model; wherein the virtual model is used to generate at least one type of scene;

[0038] The aforementioned virtual models can be models from different virtual scenes. For example, virtual walls, doors, windows, floors, and fences in architectural scenes; various virtual machines in mechanical scenes; virtual trees, beaches, rocks, and rivers in natural environment scenes; and virtual glass, lighting fixtures, appliances, and furniture in indoor environments. These virtual scenes typically refer to virtual scenes within games. They can be a single type of virtual scene or include multiple types. For instance, it could be a virtual scene containing architectural scenes, natural scenes, or only architectural scenes.

[0039] Specifically, the virtual models mentioned above are usually created using modeling software. In order to save the production cycle of virtual scenes, the size of each virtual model is usually pre-planned so that the size of all virtual models is a regular integer.

[0040] Step S104: Identify the construction location of the virtual model in the virtual scene, and construct the virtual model according to the construction location to generate the initial virtual scene;

[0041] Specifically, the above steps can be performed using pre-created blueprints. These pre-created blueprints typically include multiple blueprints, each used for different functions, such as generating an initial virtual scene, generating architectural virtual scenes, or applying materials to the model. Additionally, each blueprint includes multiple functional nodes, each used for different functions, such as identifying the placement of the virtual model or constructing the virtual model. The placement of the virtual model can be pre-configured during virtual model creation or determined in the game engine using blueprints based on the virtual model's dimensions. The initial virtual model typically refers to a virtual scene without any model rendering.

[0042] Specifically, when opening a virtual model in the game engine and building each virtual model, the required functions are first enabled, and a blueprint is created based on the target function nodes. Then, based on the enabled functions and the created blueprint, the model size and building position of the virtual model can be automatically identified. Finally, the virtual model that conforms to the building size can be automatically built based on the model size and building position. This building process can be automatic or manual.

[0043] Step S106: Perform material processing on the specified virtual model in the virtual model to obtain the target virtual model;

[0044] The aforementioned specified virtual model can be virtual equipment, virtual machines, virtual glass, virtual rivers, virtual rocks, etc., within a virtual scene. The target virtual model possesses a realistic and natural visual effect, typically including wear and tear effects, such as wear on metal, wood, or plastic, which can include paint chipping, polishing, or breakage. It also includes material blending effects, such as the blending of stone and sand materials. The blueprint is created by combining multiple target functional nodes, which at least include: VertexNormalMS node, IF node, LinearInterpolate node, DistanceToNearestSurface node, Absolute Worldposition node, CameraPosition node, PixelDepth node, and various function nodes.

[0045] The VertexNormalMS node outputs the expression for the vertex normals in world scene space; the IF node compares two inputs and then passes the expression for one of the other single input values ​​based on the comparison result; the LinearInterpolate node is an expression that interpolates between two input values ​​using a third input as the masking parameter; the DistanceToNearestSurface node is an expression for the distance from the nearest surface to the material; the Absolute Worldposition node outputs the expression for the current pixel's position in global space; the CameraPosition node outputs a 3D vector value representing the camera's position in world scene space; the PixelDepth node outputs the depth of the currently rendered pixel, i.e., the expression for the distance between the pixel and the camera; various function nodes include at least the BreakOutFloat3Components and MakeFloat2 functions. The BreakOutFloat3Components function takes a 3D vector as input and retrieves and outputs a scalar for a single channel. The MakeFloat2 function creates a 2D vector from a series of scalar inputs.

[0046] Specifically, a target texture can be drawn at a specified location on a specified virtual model, or a target material can be assigned to it to obtain the target virtual model. The target texture and target material are usually pre-generated to give the target virtual character a realistic and natural display effect.

[0047] Step S108: Generate the target virtual scene based on the initial virtual scene and the target virtual model.

[0048] After creating the initial virtual scene and the target virtual model, the virtual model in the initial virtual scene can be rendered to make the initial virtual scene more realistic and natural. The target virtual model can then be placed into the initial virtual scene to generate the target virtual scene. The aforementioned target virtual scenes include at least: architectural scenes, natural environment scenes, indoor scenes, and mechanical scenes.

[0049] It should be noted that the aforementioned "blueprint" can serve as one of the execution entities for the virtual scene generation method described above. Alternatively, it can be understood as executing the steps of the virtual scene generation method using a pre-created blueprint for reuse / invocation. This blueprint refers to a visual script.

[0050] This invention provides a method for generating virtual scenes, which involves: acquiring a pre-generated virtual model; identifying the construction position of the virtual model in the virtual scene and constructing the virtual model according to the construction position to generate an initial virtual scene; applying material processing to a specified virtual model within the virtual model to obtain a target virtual model; and generating the target virtual scene based on the initial virtual scene and the target virtual model. This method generates at least one type of virtual scene by programmatically constructing the virtual model and applying material processing to the specified virtual model, eliminating the need to manually draw different types of virtual scenes, reducing the labor costs of creating virtual scenes, saving production time, and thus improving the scene effect and production efficiency of virtual scenes.

[0051] Currently, when creating realistic architectural scenes, the main approach is to first create component models, and then achieve variations in detail through different combinations of these components. However, the assembly process relies entirely on visual observation and manual splicing. This method, relying solely on visual observation and manual splicing, easily leads to misalignment, overlap, or cracks at the joints. Eliminating these errors requires a considerable amount of time.

[0052] The virtual model mentioned above includes a first component model and a second component model, which are used at least to generate architectural scenes; the first component model and the second component model are each preset with marker points; the marker points are used to indicate the connection positions between the first component model and the second component model;

[0053] This embodiment uses a virtual model as an example of a building scene. The first component model typically refers to a building model, such as various building walls, while the second component model typically refers to accessory models within the building, such as doors and windows. The marker points mentioned above are pre-configured anchor points.

[0054] The first component model and the second component pricing model mentioned above are created in the following manner:

[0055] First, set the grid size in the modeling software. Specifically, you can use the Grid Spacing function to set the side length of each grid cell in the background grid of the virtual model, for example, to 100cm. Figure 2 As shown, set the input box for Grid Spacing to 100cm. Grid Spacing serves as the reference unit for precise model positioning. Since directly building components within an architectural scene can easily lead to light leaks or misalignments, the dimensions of the first and second component models need to be carefully planned. Specifically, the background grid of the virtual model can be used as a reference to ensure that the dimensions of the created models are regular integers. For example... Figure 3 The first component model shown has dimensions that are regular integers.

[0056] Additionally, for the second component model, which consists of door and window fittings with non-integer dimensions, anchor points can be configured at specific locations in the second component model (such as corners or below the center line of doors and windows) and at corresponding locations in the first component model. For example, such as... Figure 4 The marker points (i.e., anchor points) set on the door model (corresponding to the second component model mentioned above) and the door frame model (object of the first component model mentioned above) are shown. For example... Figure 5 The marker points (i.e. anchor points) are set on the window model (corresponding to the second component model above) and the window frame model (object of the first component model above).

[0057] One possible implementation of the above steps—identifying the location of the virtual model, building the virtual model based on the location, and generating the initial virtual scene—is as follows:

[0058] The model size of the first component model is determined by capturing the mesh and the capture angle, and the first component model is built according to the model size. The capturing mesh and capture angle are used to determine the model size of each first component model, and first component models with the same model size are built together. A component snap-fit ​​system is used to detect the distance between preset marker points of the first component model and preset marker points of the second component model. The component snap-fit ​​system is used to identify the preset marker points of the first component model and the second component model in real time, and calculate the distance between the preset marker points of different models. When the distance is less than a preset threshold, the second component model is controlled to be built at the target position of the first component model, generating an initial virtual scene.

[0059] The aforementioned preset thresholds can be set according to actual needs. Specifically, when assembling (building) the first and second component models in the game engine, it is necessary to enable the game engine's mesh snapping and angle snapping functions. A diagram illustrating these functions is shown below. Figure 6 As shown. By using the mesh snapping and angle snapping functions, the model dimensions of the first component model can be automatically identified. Based on these dimensions, the various first component models can be automatically and perfectly aligned, such as... Figure 7 The two first component models shown are now complete.

[0060] When building the second component model onto the first component model, you first need to enable the ModularSnap System, as shown in the diagram below. Figure 8 As shown. This component snap-fit ​​system is an externally loaded plugin. In actual implementation, the operator only needs to move the second component model near the first component model. When the distance between the preset marker points of the first and second component models is less than a preset threshold, the second component model can be automatically snapped to the first component model. For example, the anchor points of the door and window models snap to the corresponding anchor points on the door and window frames. That is to say, initially, the window model needs to be manually moved roughly, but when the model enters the effective range of the anchor points, it will automatically be pulled to the correct position, just like an iron block entering the magnetic field of a magnet. The final generated initial virtual scene can be an architectural scene, a natural environment scene, an interior scene, etc. For example, as shown... Figure 9 The initial virtual scene shown is an architectural scene.

[0061] In this method, the first component model can be automatically controlled to splice by using the mesh capture function, the angle capture function, and the component snap-fit ​​system. At the same time, the second component model can be automatically snapped to the corresponding position of the first component model by using the pre-set anchor points. This improves the scene effect of the virtual scene, avoids splicing errors, and improves production efficiency.

[0062] The above-described step of controlling the second component model to be built at the target position of the first component model to generate the initial virtual scene when the distance is less than a preset threshold can be implemented as follows: When the distance is less than the preset threshold, it is determined that preset marker points in the first component model are associated with preset marker points in the second component model; based on the position of the associated marker points, the second component model is controlled to be built to the target position of the first component model to generate the initial virtual scene; wherein, the preset marker points of the second component model coincide with the preset marker points of the first component model. The aforementioned target position is the position of the marker points in the first component model associated with the second component model.

[0063] Typically, pre-set markers are interconnected. Therefore, when placing the second component model onto the corresponding position of the first component model, the two component models will automatically snap together only if their markers are interconnected. In other words, when the distance between the markers on the first and second component models is less than a preset distance, the two component models will automatically snap together, with the markers serving as the reference point for snapping. For example, if the first component model has a first and a second marker, and the second component model has a third and a fourth marker, with the first and third markers interconnected, the first marker on the first component model will be placed at the position of the third marker on the second component model, and the second marker on the first component model will be placed at the position of the fourth marker on the second component model.

[0064] Currently, placing a door in the correct position requires manual operation and visual observation, which is slow and prone to errors. Using anchor points (the interconnected markers mentioned above) acts like a magnet; simply placing the anchor point in the correct location allows the model to be automatically pulled into the correct position when moved near it. This method is highly efficient when constructing large buildings with many doors and windows.

[0065] When creating sci-fi scenes primarily featuring mechanical models, the wear and tear effects on the edges of mechanical parts are often achieved by hand-painting. Creating these effects by hand requires unUVing the model, adding a wear and tear layer to the texture file, and finally manually painting the edges. This process is repeated for each mechanical part, making it extremely time-consuming.

[0066] Therefore, the aforementioned virtual model refers to a mechanical model within a virtual scene; where the mechanical model in the virtual scene can be various metal machine models, such as generators, transformers, metal cabinets, etc.

[0067] One possible implementation of the above steps for processing the materials of a specified virtual model in a virtual model to obtain the target virtual model is as follows:

[0068] (1) Determine the edge region of the specified virtual model;

[0069] The aforementioned edge regions typically refer to the prominent edges of the model, for example, such as... Figure 10 The diagram shows a specified virtual model, where the white area represents the edge region of the specified virtual model. In other words, the aforementioned edge region can be understood as the area with sharp edges in the specified virtual model.

[0070] One possible implementation is as follows: obtain the vertex normal information of the specified virtual model, determine the surface curvature of the specified virtual model based on the vertex normal information, and determine the edge region of the specified virtual model based on the surface curvature.

[0071] Specifically, the material system's global vertex normal (VertexNormalMS) node, in conjunction with the (IF) node, is used to generate a function that identifies the surface curvature of the model to locate the model's prominent edges, i.e., the aforementioned edge regions. Specifically, the material system's global vertex normal (VertexNormalMS) node acquires and outputs the vertex normal information of the specified virtual model; then, based on the vertex normal information, the surface curvature of the specified virtual model is calculated; and the edge regions of the specified virtual model are determined based on the surface curvature using the IF node.

[0072] A higher curvature indicates a greater degree of curvature in the curve. Therefore, a curvature threshold can be set; if the curvature of the model surface exceeds this threshold, the model surface is defined as the edge region of the virtual model. In this method, specific functional nodes within the game engine can automatically determine the model's edges, eliminating the need for manual selection by developers and significantly improving production efficiency.

[0073] (2) Obtain the pre-generated first target material, assign the first target material to the edge area to obtain the target virtual model, so that the target virtual model has the display effect of edge metal wear; wherein, the first target material is a noise material that imitates damage.

[0074] The first target material mentioned above is pre-generated. Specifically, it can be generated based on the model material of a specified virtual model. For example, if the model material of the specified virtual model is metal, then a noise material with metal wear can be generated. For instance, as shown... Figure 11 The diagram shown simulates a damaged, noisy material.

[0075] Specifically, you can directly apply the first target material to the edge area. You can also use the edge area as a mask, such as... Figure 10 As shown, the white area is a mask. By adjusting certain parameters and multiplying the first target material by the mask, a target mask with an irregular wear effect at the edges can be obtained, as shown. Figure 12 As shown, the edge area at this point has an irregular wear effect. This allows us to obtain the aforementioned target virtual model, giving the edge area of ​​the target virtual model a metallic wear display effect.

[0076] Alternatively, the obtained mask can be used to generate a damaged material mask through a Linear Interpolate node and applied to the metal material (i.e., the area of ​​the specified virtual model excluding the edge areas). The resulting target virtual model will then exhibit a metal wear effect not only in the edge areas but also in other areas. For example, ... Figure 13 As shown, not only the edge areas have a metallic wear effect, but other areas also have a metallic wear effect.

[0077] In this method, the edges and corners of a specified virtual model are determined automatically through a programmed process, and pre-generated noise materials simulating damage are automatically applied to the edge and corner areas, intelligently achieving a metallic effect of edge wear. This eliminates the need for developers to manually draw textures, significantly saving time on texture drawing and improving production efficiency.

[0078] When creating natural scenes, blending different objects, such as large rocks or trees inserted into the ground, with the ground is often achieved by manually drawing textures or using vertex shaders. However, this method requires drawing each model individually based on the specific blending requirements, which is very time-consuming.

[0079] Based on this, the aforementioned designated virtual model refers to a natural scenery model in a virtual scene. The designated virtual model includes a first designated virtual model and a second designated virtual model. The first designated virtual model can be a rock in water, a rock on grass, a rock on a beach, a tree on the ground, etc. The second designated virtual model can be water, a desert, grassland, etc. For example,... Figure 14 As shown, the first designated virtual model is the stone model in the figure, and the second designated virtual model is the desert model located below the stone model.

[0080] Another possible implementation of the above steps of processing the material of a specified virtual model in a virtual model to obtain a target virtual model is as follows: Determine the contact area between the first specified virtual model and the second specified virtual model; wherein, the first specified virtual model is partially or entirely located on a specified surface of the second specified virtual model; obtain a pre-generated second target material, and apply the second target material to the contact area to obtain the target virtual model, so that the target virtual model has a display effect of natural material transition; wherein, the second target material is a mixed material of the material of the first specified virtual model and the material of the second specified virtual model.

[0081] Specifically, the material difference between the first specified virtual model and the second specified virtual model can be mixed to obtain a mixed material, which is the second target material mentioned above. In actual implementation, the DistanceFields function of the game engine can be enabled first, such as... Figure 15 The "Generate Mesh Distance Field" is shown. Then, the DistanceToNearestSurface node is used to identify the contact area, also known as the intersection range, between the first and second specified virtual models. Specifically, the absolute world position nodes can be used to determine the absolute world positions of the first and second specified virtual models, and the areas with the same position are identified as the contact area. Then, the second target material is applied to the contact area, finally resulting in a virtual model with a material blending effect. For example, as shown... Figure 16 As shown, the area where the stone contacts the ground has a natural transition in material properties.

[0082] In one possible approach, after determining the contact area, this area is multiplied by a second target material to obtain a natural transition effect. Using the area with this effect as a mask, the rock material and the ground material can be blended using linear interpolation. This results in a smart material that can automatically recognize the intersection of the model and the terrain and generate a natural transition. In use, the model with this material is simply placed in the scene, and it will automatically produce natural changes, saving a significant amount of processing time.

[0083] In the above method, the contact area between models is determined automatically through a program, and the display effect of material transition in the contact area is intelligently realized. There is no need for developers to draw manually, which saves a lot of production time and improves production efficiency.

[0084] Delayed decals are a very common and efficient way to enrich scenes. However, in game engines, delayed decals generally don't display correctly on semi-transparent materials, such as... Figure 17 As shown, time-lapse decals display correctly on regular materials, but not on transparent materials. Related techniques typically involve manually drawing time-lapse decals on transparent or semi-transparent virtual models, which is time-consuming.

[0085] Based on this, the above-mentioned virtual model is a virtual model with transparent or semi-transparent materials; a virtual model with transparent materials can be a glass virtual model, etc., and a semi-transparent virtual model can be a colored glass model, a patterned glass model, or a water model, etc.

[0086] Another possible approach to the steps described above for applying material processing to a specified virtual model within a virtual model to obtain the target virtual model is as follows:

[0087] (1) Obtain the virtual cube and preset texture;

[0088] The aforementioned virtual cube can also be called a virtual cube matrix. This virtual cube can be understood as being composed of many points, and these points can be called a virtual cube matrix. For example, such as... Figure 18 The diagram shows a virtual cube. After processing based on the virtual cube and preset textures, when this virtual cube comes into contact with any virtual model in the virtual scene, the preset texture will be displayed on the contact surface.

[0089] (2) Based on the virtual cube and the preset texture, when the specified virtual model intersects with the virtual cube, the preset texture is displayed on the intersection area of ​​the specified virtual model to obtain the target virtual model, so that the target virtual model has the display effect of delayed decal.

[0090] The above-described steps, based on a virtual cube and a preset texture, involve displaying the preset texture on the intersection area of ​​the specified virtual model and the virtual cube when the specified virtual model intersects, thus obtaining the target virtual model and giving it a delayed decal display effect. One possible implementation is as follows:

[0091] (1) Determine the target location points within the virtual cube;

[0092] The aforementioned target location point usually refers to the location point included in the virtual cube, and the target location point is also a location point on the virtual model in the current scene, or a location point in the current scene.

[0093] (2) Calculate the target coordinates of the target location point; where the target coordinates are two-dimensional coordinates, and the target coordinates are used to: indicate the display range of the preset texture;

[0094] Calculate the first coordinate of the target location point in the virtual cube; the first coordinate is a two-dimensional coordinate; determine the target coordinate of the target location point based on the second coordinate and the first coordinate of each pixel in the preset texture; wherein, the second coordinate is a two-dimensional coordinate.

[0095] One possible implementation of the above steps for calculating the first coordinates of the target location point in the virtual cube is as follows: calculate the third coordinates of the target location point in the virtual cube; the third coordinates are three-dimensional coordinates; sample the coordinate values ​​of the first and second coordinate axes in the third coordinates to obtain the first coordinates of the target location point in the virtual cube.

[0096] Specifically, the local coordinates (i.e., the third coordinates) of the current pixel (i.e., the target position point mentioned above) in the virtual cube matrix can be calculated using the absolute world position node, the camera position node, and the pixel depth node. Here, the current pixel refers to the pixel within the virtual cube matrix displayed on the screen.

[0097] Since the preset decal is a two-dimensional image, the coordinates of each point on the image are a set of (X,Y) values. Therefore, the (X,Y) values ​​of the current pixel are sampled using the BreakOutFloat3Components and MakeFloat2 functions. That is, the coordinate values ​​of the first and second coordinate axes in the third coordinate are sampled to obtain the first coordinates of the target position point in the virtual cube.

[0098] After obtaining the first coordinates of the target location point in the virtual cube, the second and first coordinates of each pixel in the preset texture are used as inputs to the Multipiy node, and the target coordinates of the target location point, i.e., the two-dimensional coordinates of the preset decal displayed within the virtual cube, can be output.

[0099] Additionally, it should be noted that this embodiment uses a virtual cube to simulate the function of a delayed decal. Therefore, it is necessary to calculate the range of this virtual cube, which is the area to be used to display the decal. Thus, it is necessary to determine whether all pixels are within the range of the virtual cube. If they are within the virtual cube, a preset decal will be displayed. If they are not within the virtual cube, no image will be displayed.

[0100] (3) Based on the target coordinates of the target location point and the preset texture, when the specified virtual model intersects with the virtual cube, the preset texture is displayed on the intersection area of ​​the specified virtual model to obtain the target virtual model, so that the target virtual model has the display effect of delayed decal.

[0101] The target coordinates of the target location point are stored in the alpha channel of the preset material sphere, and the preset texture is stored in the color channel of the material sphere. The material sphere is assigned to the static mesh. When the specified virtual model intersects with the virtual cube, the intersection area of ​​the specified virtual model and the target coordinates of the intersection point in the intersection area are determined. Using the material sphere, based on the target coordinates of the intersection point, the preset texture is displayed at the intersection point, and the preset texture is not displayed at other target locations besides the intersection point, thus obtaining the target virtual model, so that the target virtual model has a delayed decal display effect.

[0102] One possible implementation involves first calculating the positions of all points within a virtual cube using nodes, and then calculating the positions of points where the virtual cube intersects with other models. This result is then connected to the alpha channel of the material. The desired result is that the points at these intersections display the decal content, while points outside the intersections do not. Only the alpha channel in the material has this function (essentially, a function to control which points are displayed and which are not). Later, after applying an image to the color channel, the decal content will be displayed at specific locations on the model. For example,... Figure 19 As shown, preset textures are displayed on transparent glass. This method of simulating time-delay decals retains all the characteristics and working methods of the original time-delay decals, and can perfectly display patterns on semi-transparent materials, also compensating for the shortcomings of some game engines' original time-delay decals. Furthermore, this method can not only be applied to displaying patterns on glass, but also to displaying special effects such as skill releases on water surfaces. It can implement time-delay decal functionality on all materials, offering a wider range of applications than the time-delay decals built into game engines.

[0103] In the above method, transparent and semi-transparent models can be made to have the display effect of time-delay decals through a programmed automatic method. This not only retains all the characteristics and working methods of the original time-delay decals, but also perfectly displays the pattern on the semi-transparent material. There is no need for developers to draw manually, which saves a lot of production time and improves production efficiency.

This method utilizes specified functional nodes within the game engine to pre-create blueprints through logical combinations, enabling the procedural construction of virtual models and the application of material processing to specified virtual models to generate at least one type of virtual scene. This eliminates the need for manually drawing different types of virtual scenes, reducing the labor costs of virtual scene creation, saving production time, and thus improving the scene effects and production efficiency of virtual scenes.
