Description

Technical Field

[0001] The present invention relates to the technical field of model rendering, and in particular to a method, device and electronic equipment for generating a virtual scene. Background Art

[0002] In the editing and production of virtual scenes, it is usually necessary to use terrain tools, such as Terrain, to edit and produce the target scene. In conventional scene editing and production, the scene model object can usually be directly inserted into the target scene, or it can be spliced ​​with the terrain module in the target scene through modular model components. However, in the above-mentioned scene production method, defects will appear at the junction of the scene model object and the surface of the target scene, as well as at the connection between the model component and the terrain module. In the related art, transparent vegetation models or transparent patches are usually used to block the defects at the junction. However, this method of scene production that requires vegetation models will result in many obscured model faces and vertices in the resulting scene, and these obscured model faces and vertices will also be rendered, which will inevitably increase the loss of game performance. In addition, this scene production method that requires additional transparent patches will also increase the performance consumption of transparent rendering. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0029] In virtual scene editing, a terrain tool such as Terrain (a terrain system of an engine software, generally used for drawing material fusion, drawing ups and downs, and batch brushing vegetation) is usually used. The Terrain has its own series of file forms and implementation modes, and it is not necessary for all game types to have these Terrain parameters and record files. Therefore, in some game types, performance waste is inevitable. In conventional scene editing, scene model objects can be directly inserted into a target scene, or can be spliced with a terrain module in the target scene through a modular model component. However, in the above scene production methods, defects occur at the junction of the scene model object and the ground surface of the target scene, and at the connection of the model component and the terrain module.

[0030] For example, a virtual object (a stone) is placed on a terrain surface. In the real world, the junction of the stone and the ground surface is not just a line, but there is mud or moss as a medium to make the ground and the stone perfectly integrated. Therefore, a vegetation model is used to cover the joint to cover the defects at the joint. However, in this way of producing a scene by using a vegetation model, many model surfaces and vertices are covered, and these covered model surfaces and vertices are also rendered, which inevitably increases the loss of game performance.

[0031] In addition, when the modular model component is spliced with the terrain module in the target scene, since the value of the terrain module changes with the size of the terrain chunk file, it is difficult to lock the uv position like the model, so that a gap occurs at the junction of the Terrain and the scene modular model, and an additional surface is needed to cover the defects at the joint, which also increases the performance consumption of the surface rendering.

[0032] Based on this, the embodiment of the present application provides a virtual scene generation method, device and electronic equipment, which can be applied to a device having a function of generating a virtual scene, and is especially suitable for MOBA (Multiplayer Online Battle Arena) games, MMORPG (Massive (or Massively) Multiplayer Online Role-Playing Game) games, and games with buff effects on the soles of characters and flat road surfaces.

[0033] To facilitate the understanding of the present embodiment, first, a virtual scene generation method disclosed by the present embodiment is introduced in detail, as shown in the following formula (I): Figure 1 The method comprises the following steps.

[0034] Step S102: Acquire a scene model; wherein the scene model includes: a terrain module and at least one object module spliced ​​with the terrain module;

[0035] The above scene model refers to a scene model built in a modular production method. Specifically, you can install the Terrain tool in the game engine (such as Neox2.0) to build the scene in a modular production method. First, dig a hole in the plane to get the terrain module. In fact, it is like building blocks. A complex scene is made by piecing together multiple small modules of the same specifications. Then, pre-made object modules (such as Figure 2 As shown, it includes object modules of various shapes) spliced ​​to the terrain module to obtain Figure 3 The scene model shown here is identical in shape between the object and terrain modules to ensure smooth integration between them. For example, the top view of the object module is square. Besides squares, triangles and hexagons can also serve as object modules. Finally, export the scene model from Neox to .fbx or .obj, then import it into 3ds Max.

[0036] Step S104, in response to the deletion operation on the specified face in the terrain module, obtaining a first model face of the scene model; wherein the first model face has a specified orientation; the specified face is a face in the terrain module that is blocked by the object module;

[0037] Since the scene model is composed of the object module and the terrain module, the splicing area of ​​the terrain module, that is, the specified surface, will also participate in the rendering process to increase the rendering performance. Therefore, the specified surface in the terrain module can be deleted in the Max software. The first model surface of the scene model obtained is as follows: Figure 4 That is, in 3dmax, delete the surface with high and low difference in Terrain, and keep the upper and lower plane parts. The above specified direction is usually the horizontal plane of the terrain module. In the terrain module, since there are multiple heights, each height has the horizontal plane of the terrain module, such as Figure 4 The shown includes four layers.

[0038] Step S106 , merging the first model surface and the surface with the specified orientation in the object module to obtain a merged surface;

[0039] Since the terrain module and the object module are spliced ​​together and may have different textures, in order to reduce splicing defects and rendering effects, the first model surface and the surface with a specified orientation in the object module can be merged. Specifically, in the Max software, merge the surfaces in the object module that are connected to the first model surface, such as Figure 5The partial model of the scene model shown in FIG. 1 , wherein the square-shaped area is the first model surface; the triangular-shaped area is the surface of the object module that has the same orientation as the first model surface. The surface with a specified orientation in the object module can also be understood as the upper and lower planes of the object module. For example, see Figure 5 As shown, the first model surface of the grid-shaped area 1 can be merged with the surface of the triangular area 2, the first model surface of the grid-shaped area 3 can be merged with the surface of the triangular area 4, and the surface of the dotted area (that is, the triangular area) can be merged with the first model surface with the same orientation, and finally the above-mentioned merged surface can be obtained, as shown in FIG. Figure 6 As shown, the plane at each height is a complete merged surface.

[0040] Step S108 , rendering the merged faces and faces other than those in the specified direction in the object module to generate a target virtual scene.

[0041] The faces other than the specified directions in the object module above refer to the side faces of the object module, such as Figure 5 The scene model shown includes faces other than the merged faces. Specifically, the merged faces and faces other than the specified directions in the object module can be input into the game engine, and the baking tool of the ue4 engine can be used through the plug-in to make a lighting effect map for the merged faces and faces other than the specified directions in the object module. Since the rendering results need to be transmitted back to the game engine, the rendering parameters need to be set before rendering. The same rendering parameters need to be set in the game engine and the ue4 engine borrowed by the plug-in. For example, the accuracy of the rendering parameters is 1024. Finally, after the parameters are set, the lighting effect map is rendered to the merged faces and faces other than the specified directions in the object module to generate the above-mentioned target virtual scene, as shown in the figure. Figure 7 As shown in the figure, only the area pointed by the arrow has a seam, and the other areas are a complete plane.

[0042] An embodiment of the present invention provides a method for generating a virtual scene, which includes obtaining a scene model; the scene model includes a terrain module and at least one object module spliced ​​with the terrain module; in response to a deletion operation on a specified face in the terrain module, obtaining a first model face with a specified orientation in the scene model; the specified face is a face in the terrain module that is blocked by the object module; merging the first model face with the face with the specified orientation in the object module to obtain a merged face; rendering the merged face and faces other than the specified orientation in the object module to generate a target virtual scene. In this method, the overall scene model is constructed in a modular manner, and faces in the terrain module that are blocked by the object module are deleted, thereby reducing unnecessary rendering and lowering the performance loss of the game; faces with the same orientation in the terrain module and the object module are merged, thereby solving the connection defects between modules in the virtual scene and improving the effect of the virtual scene.

[0043] Since there are splicing defects between the first model surface and the surface with the specified orientation in the object module, and the surface mapping is different, in order to improve the effect of the virtual model and improve rendering efficiency, the merged surface and the surfaces other than the specified orientation in the object module are rendered to generate the target virtual scene. A possible implementation method is as follows:

[0044] (1) Mapping the merged surface to obtain the target merged surface;

[0045] The above-mentioned merged surface may include multiple surfaces, so each merged surface needs to be mapped. Specifically, the channel map of the merged surface can be determined first, and then the merged surface is mapped based on the channel map to obtain the above-mentioned target merged surface.

[0046] A possible implementation method is: responding to a target material creation operation for the merged surface to obtain a target material; responding to a drawing operation for a target channel map, mixing a preset mixed map into the target material according to a preset channel order to obtain a target channel map; responding to a mapping operation for the merged surface, mapping the merged surface according to the target channel map and a preset surface map to obtain a target merged surface.

[0047] The preset channel order mentioned above can be ARGB, and the preset mixed map can be set according to actual needs. Specifically, you can export the merged surface as an fbx file in the Max software and import it into Unity. Use the third-party plug-in T4M to paste 4 surface maps for mixing in ARGB order on the T4M panel, select one of them to start drawing, and finally get the drawn target channel map, that is, the ARGB map. Then export the merged surface in the Max software to the game engine Neox2, use the material shader / x11pbr_miniterrain.surf, import the target channel map drawn in Unity into the game engine Neox2, and paste the target channel map with the surface map at the specified position of the material ball to obtain the above-mentioned target merged surface. It should be noted that because the four ARGB channels each represent a map, the order must be consistent with the order in Uniy to restore the effect. There is also a normal channel for the corresponding position in the material ball.

[0048] In the above method, the merged surface is enriched by setting the target channel map to the merged surface and performing mixed mapping processing.

[0049] (2) Rendering is performed on the target merged faces and faces other than those with the specified orientation in the object module to generate the target virtual scene.

[0050] In fact, since the planes of the scene model have been merged, it is only necessary to create one light effect map, and use the light effect map to render the surface of the scene model.

[0051] In the above method, by mapping the merged surface, the plane can be mapped Figure 1 The merged faces that have been textured and the faces other than those with the specified orientation in the object module will be rendered. The generated target virtual scene can solve the problem of texture gaps and the gaps caused by the edges of light effect maps. The expanded drawing range of the surface makes the drawing more vivid and flexible, which is more conducive to making picture layers, and the package size is smaller and the performance is better.

[0052] A possible implementation method is as follows: in response to an acquisition operation on a face other than a specified orientation of the object module, the model side face of the object module is acquired from the scene model; in response to a rendering operation on the target merged face and the model side face, the target merged face and the model side face are rendered according to pre-configured rendering parameters and a pre-drawn lighting effect map to generate a target virtual scene.

[0053] The pre-drawn light effect map is created in the game engine through a plug-in using the UE4 engine. After creation, it is returned to the game engine. Using pre-configured rendering parameters and the pre-drawn light effect map, the target merged surface and model side are rendered to generate the target virtual scene. In addition, because the rendering process requires the use of both the UE4 engine and the game engine, the rendering parameters of the UE4 engine and the game engine must be pre-set before importing the target merged surface and model side. For example, the rendering parameter precision must be set to 1024. This rendering process can also be called baking.

[0054] In Max, the faces of the scene model outside the specified orientation (i.e., the model's side faces) are exported to the game engine. Simultaneously, the target merged faces are also exported to the game engine in Unity. A lighting map is then created using the UE4 engine plugin. Finally, the target merged faces and model's side faces are rendered in the game engine using pre-configured rendering parameters and pre-drawn lighting maps to generate the target virtual scene.

[0055] In the above method, since the plane of the terrain module is merged with the plane of the object module, a light effect map can be drawn to render the scene model, which solves the defects at the seams of the planes and further improves the effect of the virtual scene.

[0056] In order to enable mapping and rendering operations on the merged surface and the side surface of the model in the subsequent rendering process, and at the same time to simplify the light effect map to one, thereby improving the rendering accuracy, the first model surface and the surface with a specified orientation in the object module are merged to obtain the merged surface. After the step, the above method also includes: responding to the UV expansion operation on the merged surface, performing 1UV expansion processing and 2UV expansion processing on the merged surface respectively, to obtain a first expansion result and a second expansion result; wherein the first expansion result is used for mapping processing in the merged surface, and the second expansion result is used for rendering the light effect in the merged surface.

[0057] It's important to note that the Terrain tool has a heightmap drawing channel for creating undulations, but it doesn't support editing triangle routing, UV unwrapping, or secondary UV processing. The T4M (Texture Tour Mask) tool, which blends four textures through the ARGB channels, is a static model and can't be used to create heights. However, the advantage of T4M is that it can be edited in professional modeling software like Max and Maya and then imported into the engine. It can edit triangle routing, perform UV unwrapping, and perform secondary UV processing. The benefit of triangle routing is that it can create richer and more detailed contours, allowing for the creation of any smooth shape.

[0058] In Max, the merged surfaces were processed with 1UV and 2UV respectively. The 1UV expansion operation was to solve the seam problem with the module caused by the size value of the Terrain tool, and the UV at the previous gap can be seamlessly connected together without any seams. The 2UV expansion operation was to solve the seams caused by insufficient lighting effect accuracy, and to maximize the use of the lighting effect map.

[0059] In the above method, by performing 1uv expansion processing and 2uv expansion processing on the merged surface, the mapping effect and rendering accuracy of the merged surface are improved.

[0060] Furthermore, in response to an acquisition operation for a face other than the specified orientation of the object module, after the step of acquiring the model side of the object module from the scene model, the above method also includes: responding to a UV expansion operation for the model side, performing 2UV expansion processing on the model side to obtain a third expansion result; wherein the third expansion result is used to render light effects on the model side.

[0061] In Max, the sides of the model were individually 2UV expanded. The purpose of the 2UV expansion operation is to avoid wasting 2U. The top and bottom surfaces are merged onto the Terrain, leaving a large gap in the module 2U. Therefore, the lighting effect map accuracy is improved by reorganizing the 2U. In this method, the rendering accuracy of the object module is improved by 2UV expansion of the side of the model.

[0062] Specifically, after performing 1UV unwrapping on the merged surface, the merged surface will store the 1UV unwrapping result. When mapping the merged surface, the 1UV unwrapping result, i.e., the first unwrapping result, can be used to map the merged surface. After performing 2UV unwrapping on the merged surface and the side surface of the model, the merged surface and the side surface of the model will store the 2UV unwrapping result. When rendering the target merged surface and the side surface of the model, the 2UV unwrapping results, i.e., the second and third unwrapping results, can be used to render the merged surface, thereby improving rendering accuracy.

[0063] In addition, the advantage of being able to edit 1u is that the gaps can be removed by UV connection, and the UV space can be used to the maximum extent. The advantage of being able to edit 2u is that the utilization rate of the light effect map is maximized, and only manual control can be used to subjectively control the weight of the light effect.

[0064] The following describes the method of constructing the above-mentioned scene model: in response to the digging operation of the digging module with a first specified size, the digging module is controlled to perform digging processing in the initial terrain module to obtain the terrain module in the scene model; in response to the splicing operation of the object module with a second specified size, the object module is controlled to be spliced ​​to the specified position of the terrain module to construct the scene model.

[0065] The first specified size is usually the same as the second specified size. The second specified size refers to the size of the object module after it is transformed into a whole cube. Specifically, in the Terrain tool, according to actual needs, the digging module is controlled to dig holes in the initial terrain module, and then Figure 2 The object modules shown are spliced ​​to the designated positions of the terrain modules as needed, and the following can be obtained in the end: Figure 3 Compared to traditional methods of making field maps, the modular production approach reduces the loss of game performance.

[0066] This approach solves the problem of gaps between terrain and modular components, as well as gaps caused by light effect map edges. It provides a more integrated and space-saving design. Modular components' light effect maps are more precise, and the terrain light effect maps are combined into a single map, saving performance. The expanded surface drawing range makes drawing more vivid and flexible, and is more conducive to creating layered graphics. This results in a smaller package size and improved performance.

[0067] Corresponding to the above method embodiment, the embodiment of the present invention provides a device for generating a virtual scene, such as Figure 8 As shown, the device includes:
