[0073] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0074] It is understood that the terms "first," "second," etc., used in this application may be used to describe various concepts herein, but unless otherwise stated, these concepts are not limited by these terms. These terms are only used to distinguish one concept from another. For example, without departing from the scope of this application, a first material may be referred to as a second material, and similarly, a second material may be referred to as a first material.

"Multiple" refers to two or more materials. For example, multiple materials can be two materials, three materials, or any integer greater than or equal to two. "Each" refers to each of the at least one materials. For example, each material refers to each of the multiple materials.

[0076] The terrain type identification method provided in this application is executed by a computer device. Optionally, the computer device is a terminal or a server. Optionally, the server is an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. Optionally, the terminal is a smartphone, tablet computer, laptop computer, desktop computer, smart speaker, smartwatch, etc., but is not limited to these.

[0077] In one possible implementation, the computer device used to identify landform types in this application embodiment is a node in a blockchain system. This node can store the generated spatial description file in the blockchain, and then the node or other nodes in the blockchain can identify the landform type of the area in the virtual space based on the spatial description file.

[0078] Figure 1 This is a schematic diagram of an implementation environment provided in an embodiment of this application. See also: Figure 1 The implementation environment includes a server 101 and a terminal 102. The server 101 and the terminal 102 are connected via a wireless or wired network. The server 101 provides a virtual space for the terminal 102, which displays the virtual space provided by the server 101. The server 101 uses the method provided in this embodiment to identify the terrain type of a region within the virtual space, thereby providing backend support for the terminal 102. Optionally, the virtual space may be a virtual space in a video game, etc.

[0079] In one possible implementation, a target application, provided by server 101, is installed on terminal 102.

[0080] Figure 2 This is a flowchart of a landform type identification method provided in an embodiment of this application. This embodiment is executed by a computer device. See also... Figure 2 The method includes:

[0081] 201. The computer device responds to the material recognition command and determines the surface material of the elements in the virtual space.

[0082] Virtual space is a space created within a computer device, also known as a virtual scene. This virtual space can be a three-dimensional space containing various elements, such as virtual terrain like grasslands, deserts, or snowfields, as well as virtual objects like virtual buildings, rocks, animals, or plants. This variety of elements enhances the diversity and realism of the virtual space. Furthermore, this virtual space can be used to simulate real-world environments under different weather conditions, such as sunny days, rainy days, foggy days, or nighttime.

[0083] The material identification command is used to request the identification of the material corresponding to a region in the virtual space. In response to the material identification command, the computer device first determines the surface material of the element in the virtual space. The element in the virtual space is rendered with at least one layer of material, which includes a surface material. The surface material refers to the material displayed on the surface of the element, and the material can be of any type.

[0084] Optionally, the material identification instruction may be sent from a terminal or other device to the computer device, or the material identification instruction may be triggered by a user operation. This application embodiment does not limit the method of obtaining the material identification instruction.

[0085] 202. The computer device controls the movement of the collision box in the virtual space. When the collision box collides with an element, the area where the collision box is located is determined as the area where the element is located.

[0086] The computer device generates a collision box and controls its movement in the virtual space. When the collision box collides with any element, it indicates that the element is included in the area where the collision box is currently located. Therefore, the computer device determines the area where the collision box is located as the area where the element that collided with the collision box is located.

[0087] The area of ​​an element in the virtual space refers to the portion of space occupied by that element in the virtual space. Optionally, the area where the element is located does not include other elements.

[0088] 203. The computer equipment determines the surface material of an element to be the material corresponding to the area where the element is located.

[0089] In this embodiment of the application, considering that the material of the area where the element is located is the surface material of the element, for the area where the element exists in the virtual space, the surface material of the element in the area can be taken as the material corresponding to the area. Therefore, after the computer device determines the surface material of the element and the area where the element is located, it determines the surface material of the element as the material corresponding to the area, thereby determining the material corresponding to the area in the virtual space based on the material of the element in the virtual space.

[0090] After determining the material corresponding to the area, the computer device performs either step 204 or step 205.

[0091] 204. The computer device responds to the first identification instruction carrying the first target area, determines the first target material corresponding to the first target area, and determines the landform type to which the first target material belongs as the landform type to which the first target area belongs.

[0092] The first identification instruction is used to request the identification of the terrain type to which the first target area belongs. The terrain type refers to the surface morphology of an area in virtual space, such as grassland, sand, snow, ocean, or forest.

[0093] Since the correspondence between regions and materials in the virtual space has been determined in step 203 above, the computer device, in response to the first identification instruction, can determine the first target material corresponding to the first target region. In this embodiment, considering that the material corresponding to a region is the surface material of the elements in the region, the material corresponding to a region can reflect the terrain type to which the region belongs. It can be considered that the terrain type to which the region belongs is also the terrain type to which the material corresponding to the region belongs. Therefore, the computer device determines the terrain type to which the first target material corresponding to the first target region belongs as the terrain type to which the first target region belongs.

[0094] 205. In response to a second identification instruction carrying a target landform type, the computer device determines a second target material corresponding to the target landform type and identifies the area corresponding to the second target material as an area belonging to the target landform type.

[0095] The second identification instruction is used to request the identification of a region in the virtual space that belongs to the target terrain type. In response to the second identification instruction, the computer device first determines the second target material that belongs to the target terrain type. Since the terrain type to which the region corresponding to the material belongs is the same as the terrain type to which the material belongs, the region corresponding to the second target material is the region that belongs to the target terrain type. Since the correspondence between the region and the material in the virtual space has been determined in the above step 202, the computer device can query the region corresponding to the second target material and then determine the region as the region that belongs to the target terrain type.

[0096] The method provided in this application determines the region where an element is located in a virtual space by controlling the movement of a collision box in that virtual space, and uses the surface material of the element in the virtual space as the material corresponding to the region where the element is located. Considering that the material corresponding to a region can reflect the terrain type to which that region belongs, it can be considered that the terrain type to which the region belongs is also the terrain type to which the material corresponding to that region belongs. Therefore, when it is necessary to identify the terrain type to which a certain region belongs, the terrain type to which the material corresponding to that region belongs can be determined as the terrain type to which that region belongs; or when it is necessary to identify a region belonging to a certain terrain type, the region corresponding to the material belonging to that terrain type can be determined as the region belonging to that terrain type. This provides an automatic way to identify terrain types without manual annotation, saving manpower and time, and improving the efficiency of terrain type identification.

[0097] In the above Figure 2 Based on the previous implementation, the elements in this virtual space include virtual terrain and virtual objects, as detailed below. Figure 3 Examples of implementations.

[0098] Figure 3This is a flowchart of another landform type identification method provided in this application embodiment. This application embodiment is executed by a computer device. See [link to flowchart]. Figure 3 The method includes:

[0099] 301. Computer devices create virtual spaces, which include virtual terrain and virtual objects.

[0100] First, it should be noted that this application embodiment uses the creation of a virtual space by the computer device as an example for illustration. In another embodiment, the virtual space can be created by other devices, in which case the computer device does not need to perform step 301, but directly performs step 302 as described below. The virtual space includes a variety of different elements, including virtual surfaces and virtual objects.

[0101] Virtual terrain, also known as virtual landscape, includes elements such as grasslands, mountains, rivers, and roads. Virtual objects are those placed on the virtual terrain during the creation of the virtual space; these objects can be virtual trees, rocks, houses, tents, or streetlights.

[0102] The virtual surface and virtual objects are rendered with materials. Materials can be seen as a combination of texture and material composition. In this embodiment, materials refer to the representation of artistic effects, such as metal, wood, sand, and grass. Materials are divided into surface materials and object materials. Surface materials can be rendered onto virtual surfaces or virtual objects, such as snow, grass, soil, or sand. Object materials can be rendered onto virtual objects, such as building materials, ruins materials, or metal materials. Each material has its own material identifier, which indicates the material; for example, the material identifier can be a material's serial number. The material identifiers for various materials are shown in Table 1 below.

[0103] Table 1

[0104] 01 grassland Ground material and object material 02 dry soil Ground material and object material 03 rock Ground material and object material 04 sandy land Ground material and object material 05 snow Ground material and object material 06 ocean Ground material and object material 07 Reserved Ground material and object material 08 Architectural structures (such as stone bridges, houses, tents, etc.) Material of an object 09 Ruins (such as Stonehenge) Material of an object 10 Metals (e.g., containers) Object Material 11 Reserved Material of an object

[0105] In Table 1, the first column is the material identifier represented by the serial number, the second column is the material, and the third column is the type of material. "Surface material and object material" means that the material can be used as both the material of virtual surface and the material of virtual object, and "object material" means that the material is used as the material of virtual object.

[0106] Figure 4 This is a schematic diagram of a virtual space provided in an embodiment of this application, such as... Figure 4As shown, Image 401 illustrates a virtual space in a video game, which includes grass, ponds, rocks, and trees. Elements of different colors in this virtual space are rendered with different materials. Image 402 shows the visualization effect of this virtual space; for example, the grass in the virtual space is rendered with a grass material, and the rocks in the virtual space are rendered with a rock material.

[0107] In one possible implementation, the computer device renders a layer of material onto a virtual surface, queries the material name corresponding to the material rendered onto the virtual surface, and establishes a correspondence between the material name and the virtual surface.

[0108] Computer equipment renders materials onto a virtual terrain, creating effects such as deserts, grasslands, and snowfields. To easily identify the material of this virtual terrain, its corresponding material name can be looked up, establishing a mapping between the material name and the virtual terrain. The material name indicates the material rendered onto the virtual terrain.

[0109] Optionally, the material name consists of a prefix and a suffix. The prefix indicates the material type, and the suffix uniquely identifies a material belonging to that type. For example, material names could be Gra-Grassland1, Gra-Grassland2, Vol-Volcano, or Sno-Snow. In "Gra-Grassland1" and "Gra-Grassland2," "Gra" indicates the material type is grass, "Grassland1" indicates sparse grass, and "Grassland2" indicates lush grass, etc. In "Vol-Volcano," "Vol" indicates the material type is volcano, and in "Sno-Snow," "Sno" indicates the material type is snow, etc.

[0110] Optionally, the virtual surface has a corresponding surface identifier, which is used to indicate the virtual surface. Establishing a correspondence between the material name and the virtual surface means establishing a correspondence between the material name and the surface identifier corresponding to the virtual surface.

[0111] In another possible implementation, the computer device renders a layer of material onto the virtual object, and the material identifier corresponding to the material rendered onto the virtual object is determined as the original material identifier of the virtual object.

[0112] In this process, only one layer of material is rendered on the virtual object. This material can be understood as the original material of the virtual object. For example, if the virtual object is a wooden table, then the wood material is rendered on the virtual object. This wood material is the original material of the virtual object. Therefore, after the computer device renders a layer of material onto the virtual object, it determines the material identifier corresponding to the material and identifies this material identifier as the original material identifier of the virtual object. This original material identifier is used to indicate the original material of the virtual object.

[0113] Optionally, in this embodiment, each material corresponds to a serial number, and different materials have different serial numbers. The serial number corresponding to the material is used as the material identifier. Optionally, the virtual object corresponds to an object identifier, which is used to indicate the virtual object. The computer device also establishes a correspondence between the original material identifier of the virtual object and the object identifier corresponding to the virtual object.

[0114] Figure 5 This is a schematic diagram of a virtual object provided in an embodiment of this application, such as... Figure 5 As shown, interface 501 displays the created virtual space, which includes a virtual tree 511. Interface 502 displays information about the virtual tree 511, such as... Figure 5 As shown, the element identifier (object identifier) ​​of the virtual tree 511 is "tree 3", the element type of the virtual tree 511 is a virtual object, and the original material identifier of the virtual tree 511 is "15", where "15" represents the wood material.

[0115] In another possible implementation, the computer device renders at least two layers of material onto the virtual object, and determines the material identifier corresponding to the first layer of material rendered onto the virtual object as the original material identifier, and determines the material identifier corresponding to the last layer of material rendered onto the virtual object as the additional material identifier.

[0116] The virtual object is rendered with at least two layers of material. The first layer of material rendered onto the virtual object, from bottom to top, can be considered the object's original material. Materials rendered above the first layer can be considered additional materials. For example, if the virtual object is a rock in snowy conditions covered with snow, its original material is stone, and its additional material is snow. Similarly, if the virtual object is a rock in grassy areas covered with moss, its original material is stone, and its additional material is grass. To facilitate subsequent identification of the rendered materials, after rendering at least two layers of material onto the virtual object, the computer determines the material identifier corresponding to the first layer. This material identifier is designated as the original material identifier of the virtual object, indicating its original material, which is the first layer of material rendered onto the virtual object. The computer device determines the material identifier corresponding to the last material layer and identifies the material identifier as an additional material identifier for the virtual object. This additional material identifier indicates the last material layer among the at least two material layers rendered on the virtual object.

[0117] In one possible implementation, the virtual object without rendered materials is a static mesh created by the computer device. After the computer device renders different materials on the static mesh, the static mesh will have different effects and form different virtual objects. For example, for the same static mesh used as a rock, if the snow material is rendered on the rock, the rock can be a rock in the snow. If the grass material is rendered on the rock, the rock can be a rock in the grass. Figure 6 This is a schematic diagram of another virtual object provided in an embodiment of this application, such as... Figure 6 As shown, interface 601 displays a spherical rock in virtual space. The first layer of material on the rock is stone, and the last layer is snow. Interface 602 shows the rock's original material identifier and additional material identifiers, such as... Figure 6 As shown, the original material identifier of the rock is "03", where "03" represents stone material, and the additional material identifier of the rock is "05", where "05" represents snow. Figure 7 This is a schematic diagram of another virtual object provided in an embodiment of this application, such as... Figure 7 As shown, interface 701 displays another spherical rock in the virtual space. The first layer of material for this rock is stone, and the last layer is grass. Interface 702 shows the original material identifier and the additional material identifier for this rock, such as... Figure 7As shown, the original material identifier of the rock is "03", where "03" represents stone material, and the additional material identifier of the rock is "01", where "01" represents grass.

[0118] 302. The computer device responds to the material recognition command and determines the surface material of the virtual ground in the virtual space.

[0119] The material identification command is used to request the identification of the material corresponding to a region in the virtual space. Elements in the virtual space include the virtual surface. After receiving the material identification command, the computer device first determines the surface material of the virtual surface in the virtual space. The virtual surface is rendered with a material layer, and the surface material of the virtual surface is the material rendered by the virtual surface.

[0120] In one possible implementation, the computer device, in response to a material identification command, obtains the material name corresponding to the virtual surface, whereby the material name describes the surface material of the virtual surface. The computer device then queries for the material corresponding to the material name and identifies the found material as the surface material of the virtual surface.

[0121] The computer device stores a mapping between virtual surfaces and material names. The material name corresponding to the virtual surface describes its surface material, as described in step 301 above. After determining the material name corresponding to the virtual surface, the computer device identifies the material corresponding to that material name as the surface material of the virtual surface. The material corresponding to the material name is also the material described by that material name. For example, if the material name of the virtual surface is "Gra-Grassland1," and the material corresponding to "Gra-Grassland1" is grass, then the computer device will identify grass as the surface material of the virtual surface.

[0122] Optionally, the computer device stores a correspondence between surface identifiers and material names. The computer device determines the surface identifier corresponding to the virtual surface and queries the material name corresponding to the surface identifier. Optionally, the computer device stores a correspondence between material names and material identifiers. The computer device queries the material identifier corresponding to the material name and determines the material indicated by the material identifier as the surface material of the virtual surface.

[0123] 303. Computer equipment determines the surface material of virtual objects in virtual space.

[0124] Elements in the virtual space also include virtual objects. After receiving the material recognition instruction, the computer device also determines the surface material of the virtual objects in the virtual space. Specifically, a virtual object may be rendered with one layer of material or at least two layers of material. If the virtual object is rendered with only one layer of material, the computer device directly determines that layer of material rendered to the virtual object as its surface material. If the virtual object is rendered with at least two layers of material, the computer device determines the last layer of material rendered to the virtual object as its surface material.

[0125] In one possible implementation, the computer device, in response to a material recognition command, queries an additional material identifier corresponding to the virtual object. If the additional material identifier is found, the material indicated by the additional material identifier is determined as the surface material. If the additional material identifier is not found, the material indicated by the original material identifier of the virtual object is determined as the surface material.

[0126] The original material identifier indicates the first layer of material rendered onto the virtual object, while the additional material identifier indicates the last of at least two layers of material rendered on the virtual object. Virtual objects in virtual space may or may not have an original material identifier. If the computer device finds an additional material identifier for a virtual object, it means that the virtual object has rendered at least two layers of material, and the additional material identifier indicates the last layer of material on the virtual object. Therefore, the computer device determines the material indicated by the additional material identifier as the surface material of the virtual object. If the computer device does not find an additional material identifier for a virtual object, it means that the virtual object has only rendered one layer of material, and the original material identifier of the virtual object indicates the first layer of material on the virtual object. Therefore, the computer device determines the material indicated by the original material identifier as the surface material of the virtual object.

[0127] 304. The computer device controls the movement of the collision box in the virtual space. Whenever the collision box collides with any element, the area where the collision box is located is determined as the area where the element is located.

[0128] The computer device generates a collision box and controls its movement in the virtual space. When the collision box collides with any element, it indicates that the element is included in the area where the collision box is currently located. Therefore, the computer device determines the area where the collision box is located as the area where the element that collided with the collision box is located.

[0129] In one possible implementation, the virtual space comprises multiple subspaces. Each subspace includes a first boundary and a second boundary, the first boundary being opposite to and identical in shape to the second boundary. The first and second boundaries are parallel to the target direction, and the cross-section of the collision box in the target direction is the same as the cross-section of the subspace in the target direction. A computer device controls the collision box to move from the first boundary to the second boundary of the subspace, and whenever the collision box collides with any element, the area where the collision box is located is determined as the area where the element is located.

[0130] For example, each subspace is a cuboid, and the collision box is also a cuboid. The first boundary of a subspace is its top edge, and the second boundary is its bottom edge. The target direction is horizontal. The horizontal cross-section of the collision box is the same as the horizontal cross-section of the subspace, and the vertical length of the collision box is less than the vertical length of the subspace. The computer controls the collision box to move from the top boundary to the bottom boundary of the subspace. When the collision box reaches the bottom boundary of the subspace, it has essentially moved to any region within that subspace, colliding with every element in the subspace and thus determining the region where each element is located.

[0131] In another possible implementation, the first boundary is the top boundary of the subspace, and the second boundary is the bottom boundary of the subspace. Whenever the collision box collides with any element, if the collision is not the first collision of the collision box in the subspace, the computer device generates indication information corresponding to the element. The indication information is used to indicate that there are other elements above the element.

[0132] Since the collision box moves from the top boundary to the bottom boundary of the subspace, when the collision box collides with the element above it for the first time in the subspace, there are no other elements above the element that collides with the collision box. When the collision box collides with the element above it for the first time in the subspace, it means that the collision box has already collided with other elements during its movement from the top boundary to the bottom boundary. Therefore, there are other elements above the element that collides with the collision box this time.

[0133] In another possible implementation, the virtual space corresponds to a coordinate system. The virtual space includes multiple three-dimensional regions, each with the same volume. The computer device constructs a cuboid with the same volume as each region. For example, if the volume of each region is 20cm*20cm*10cm, then the volume of the cuboid is also 20cm*20cm*10cm. The computer device uses this cuboid as a collision box and controls the collision box to move in the virtual space. Whenever the collision box collides with any element, the computer device determines the horizontal coordinate, vertical coordinate, and height of the collision box in the coordinate system at the time of the collision. Based on the horizontal coordinate, vertical coordinate, and height, the computer device generates coordinate information and determines the area indicated by the coordinate information as the area that collided with the collision box.

[0134] In this embodiment, since the coordinate information generated by the computer device stores the horizontal coordinate, vertical coordinate, and height, this coordinate information can be used to represent the area where three-dimensional objects such as slopes, covered bridges, and lakes are located, which is beneficial for constructing a more realistic virtual space.

[0135] 305. The computer device determines the surface material of the element to be the material corresponding to the region.

[0136] In this embodiment of the application, considering that the material of the area where the element is located is the surface material of the element, for the area where the element exists in the virtual space, the surface material of the element in the area can be taken as the material corresponding to the area. Therefore, after the computer device determines the surface material of the element and the area where the element is located, it determines the surface material of the element as the material corresponding to the area, thereby determining the material corresponding to the area in the virtual space based on the material of the element in the virtual space.

[0137] After determining the material corresponding to the area, the computer device performs step 306 or step 307.

[0138] 306. The computer device responds to the first identification instruction carrying the first target area, determines the first target material corresponding to the first target area, and determines the landform type to which the first target material belongs as the landform type to which the first target area belongs.

[0139] 307. In response to a second identification instruction carrying a target landform type, the computer device determines a second target material corresponding to the target landform type and identifies the area corresponding to the second target material as an area belonging to the target landform type.

[0140] It should be noted that the embodiments of this application only illustrate the example of virtual space including virtual surfaces and virtual objects. In another embodiment, the elements in the virtual space only include virtual surfaces, then the computer device does not need to perform the above step 303, or the elements in the virtual space only include virtual objects, then the computer device does not need to perform the above step 302.

[0141] The method provided in this application determines the region where an element is located in a virtual space by controlling the movement of a collision box in that virtual space, and uses the surface material of the element in the virtual space as the material corresponding to the region where the element is located. Considering that the material corresponding to a region can reflect the terrain type to which that region belongs, it can be considered that the terrain type to which the region belongs is also the terrain type to which the material corresponding to that region belongs. Therefore, when it is necessary to identify the terrain type to which a certain region belongs, the terrain type to which the material corresponding to that region belongs can be determined as the terrain type to which that region belongs; or when it is necessary to identify a region belonging to a certain terrain type, the region corresponding to the material belonging to that terrain type can be determined as the region belonging to that terrain type. This provides an automatic way to identify terrain types without manual annotation, saving manpower and time, and improving the efficiency of terrain type identification.

[0142] Furthermore, querying the material of a virtual object is to determine the material corresponding to a region. The last layer of material of a virtual object can better reflect the characteristics of the region. Therefore, when a virtual object has rendered at least two layers of material, the last layer of material on the virtual object is determined as the material corresponding to the region where the virtual object is located, which improves the accuracy of determining the material corresponding to the region.

[0143] Furthermore, by assigning material names and material identifiers to materials in the virtual space, establishing a correspondence between virtual surfaces and material names, and adding standardized original material identifiers and additional material identifiers to virtual objects, the ability to identify materials in the virtual space is realized, which facilitates the subsequent identification of materials corresponding to areas, thereby determining the landform type to which the material belongs as the landform type to which the area belongs.

[0144] In the above Figure 2 Based on the previous embodiment, the computer device can associate the material identifier of the surface material with the coordinate information of the area and write it into a spatial description file so that subsequent landform type identification can be performed based on the spatial description file. The specific process is detailed below. Figure 8 and Figure 9 Examples of implementations.

[0145] Figure 8 This is a flowchart of another landform type identification method provided in this application embodiment. This application embodiment is executed by a computer device. See [link to flowchart]. Figure 8 The method includes:

[0146] 801. The computer device responds to the material recognition command and determines the surface material of the elements in the virtual space.

[0147] 802. The computer device controls the movement of the collision box in the virtual space. When the collision box collides with an element, the area where the collision box is located is determined as the area where the element is located.

[0148] The process of steps 801-802 is the same as that of steps 201-202 or steps 302-304 mentioned above, and will not be described again here.

[0149] 803. The computer equipment associates the material identifier of the surface material with the coordinate information of the area and writes it into the spatial description file.

[0150] The computer device determines the material identifier corresponding to the surface material of an element and determines the coordinate information of the area where the element is located. It associates the material identifier with the coordinate information and writes it into a spatial description file, thereby establishing a correspondence between materials and areas. This allows for subsequent direct querying of the material corresponding to a certain area or the area corresponding to a certain material based on the spatial description file.

[0151] In one possible implementation, the content of the space description file is as follows: X / L|Y / W|Z / H|ID. Here, ID represents the material identifier, and X, Y, Z, L, W, and H are obtained using the method in step 304. Specifically, X represents the x-coordinate of the collision box when it collides, Y represents the y-coordinate of the collision box when it collides, Z represents the height of the collision box when it collides, L represents the length of a region in the virtual space, W represents the width of the region, and H represents the height of the region.

[0152] In one possible implementation, each element in the virtual space corresponds to an indicator message. This indicator message indicates that other elements exist above the element. The generation method for this indicator message is described in step 304 above. The computer device associates the material identifier of the surface material, the coordinate information of the region, and the indicator message of the element into a spatial description file. Subsequently, when querying the spatial description file, if the corresponding material identifier, coordinate information, and indicator message are found, it indicates that the material corresponding to the region indicated by the coordinate information is the material indicated by the material identifier, and that other elements exist above the region indicated by the coordinate information.

[0153] 804. The computer device responds to the first identification instruction carrying the first target area, determines the first coordinate information corresponding to the first target area, queries the first material identifier corresponding to the first coordinate information in the spatial description file, and determines the material indicated by the first material identifier as the first target material.

[0154] The first identification command is used to request the identification of the terrain type to which the first target area belongs. In response to the first identification command, the computer device determines the first coordinate information corresponding to the first target area. This first coordinate information refers to the location of the first target area in the virtual space. Since the spatial description file stores the coordinate information and corresponding material identifiers, the computer device can directly query the spatial description file for the first material identifier corresponding to the first coordinate information. The material indicated by this first material identifier is also the first target material corresponding to the first target area.

[0155] 805. The computer equipment determines the landform type to which the first target material belongs as the landform type to which the first target area belongs.

[0156] Considering that the material corresponding to a region is the surface material of the elements in the region, the material corresponding to a region can reflect the landform type to which the region belongs. It can be considered that the landform type to which the region belongs is also the landform type to which the material corresponding to the region belongs. Therefore, the computer device determines the landform type to which the first target material corresponding to the first target region belongs as the landform type to which the first target region belongs, thereby realizing the identification of the landform type to which the first target region belongs.

[0157] The method provided in this application, after determining the material corresponding to a region, associates the region's coordinate information with the material identifier and writes it into a spatial description file, realizing an automated process for generating spatial description files. Subsequently, when it is necessary to query the material corresponding to a region, it can be queried directly in the spatial description file without manual annotation, reducing the risk of errors in manual annotation, improving query speed, and further realizing the automated identification of the landform type to which any region belongs.

[0158] Figure 9 This is a flowchart of another landform type identification method provided in this application embodiment. This application embodiment is executed by a computer device. See [link to flowchart]. Figure 9 The method includes:

[0159] 901. The computer device responds to the material recognition command and determines the surface material of the elements in the virtual space.

[0160] 902. The computer device controls the movement of the collision box in the virtual space. When the collision box collides with an element, the area where the collision box is located is determined as the area where the element is located.

[0161] 903. The computer equipment associates the material identifier of the surface material with the coordinate information of the area and writes it into the spatial description file.

[0162] The process of steps 901-903 is the same as that of steps 801-803 above, and will not be repeated here.

[0163] 904. The computer device responds to the second identification instruction carrying the target terrain type and determines the second target material corresponding to the target terrain type.

[0164] The second identification instruction is used to request the identification of a region in the virtual space that belongs to the target terrain type. In response to the second identification instruction, the computer device determines the second target material corresponding to the target terrain type. The second target material corresponding to the target terrain type refers to the target material that belongs to the target terrain type.

[0165] For example, if the target terrain type is snow, then the material of the second target is snow; as another example, if the target terrain type is sand, then the material of the second target is sand.

[0166] 905. The computer equipment determines the second material identifier corresponding to the second target material, queries the second coordinate information corresponding to the second material identifier in the spatial description file, and determines the area indicated by the queried second coordinate information as the area belonging to the target landform type.

[0167] Considering that the material corresponding to a region is the surface material of the elements within that region, the material corresponding to a region can reflect the terrain type to which that region belongs. Therefore, it can be assumed that the terrain type of the region corresponding to the material is the same as the terrain type to which the material itself belongs. Thus, the region corresponding to the second target material is a region belonging to that target terrain type. Since the spatial description file stores coordinate information and corresponding material identifiers, the computer device determines the second material identifier corresponding to the second target material and then directly queries the spatial description file for the second coordinate information corresponding to that second material identifier. The region indicated by this second coordinate information is also a region belonging to that target terrain type.

[0168] The method provided in this application, after determining the material corresponding to a region, associates the region's coordinate information with the material's identifier and writes it into a spatial description file, thus realizing an automated process for generating spatial description files. Subsequently, when it is necessary to query the material corresponding to a region, it can be queried directly in the spatial description file without manual annotation, reducing the risk of errors in manual annotation, improving query speed, and further realizing the automated identification of regions belonging to any landform type.

[0169] Figure 10 This is a schematic diagram of a virtual space construction method provided in an embodiment of this application, such as... Figure 10 As shown, the method includes the following:

[0170] (i) Material Generation: The computer device generates various materials, including surface materials and object materials. Surface materials are rendered onto the virtual ground, such as grass, snow, and sand. Object materials are rendered onto virtual objects, such as building materials and metal materials. The computer device assigns a corresponding material identifier to each material, which is used to indicate the material.

[0171] (II) Generating Virtual Surfaces and Virtual Objects: The computer device generates virtual surfaces, renders surface materials onto them to make the virtual surfaces appear as grasslands, snowfields, rivers, or deserts, and assigns corresponding material names to the virtual surfaces. The computer device generates virtual objects, renders object materials onto them to make the virtual objects appear as trees, houses, or bridges, and assigns original material identifiers and additional material identifiers to the virtual objects.

[0172] (III) Constructing Virtual Space: Computer devices place generated virtual objects onto a virtual surface to form a virtual space. The virtual space can then be supplemented and optimized to make it richer and more aesthetically pleasing.

[0173] (iv) Exporting the Virtual Space File, Virtual Space Description File, and Installation Package File: Based on the created virtual space, the computer device exports a virtual space file, and then exports a virtual space description file and an installation package file based on this virtual space file. The virtual space file includes the virtual space itself; the virtual space description file includes the mapping between region coordinates and material identifiers; and the installation package file is a simplified version of the virtual space file. The virtual space description file is used during server runtime to allow the server to query the mapping between regions and materials, while the installation package file is used when installing applications on the terminal.

[0174] Figure 11 This is a schematic diagram of a spatial description file generation method provided in an embodiment of this application, such as... Figure 11 As shown, the method includes the following:

[0175] 1101. Generating a Virtual Object Identification File: The computer device traverses the virtual objects in the virtual space. If an additional material identifier corresponding to the virtual object is found, this additional material identifier is designated as the surface material identifier of the virtual object, indicating the surface material of the virtual object. If no additional material identifier is found, the original material identifier of the virtual object is retrieved and designated as the surface material identifier of the virtual object. The computer device generates an identification file for the virtual object, which includes the object identifier and the surface material identifier of the virtual object.

[0176] 1102. Generating a Virtual Surface Identification File: The computer device traverses the virtual surfaces in the virtual space, queries the material name corresponding to the virtual surface, and determines the surface material identifier of the virtual surface based on the material name. The computer device generates a virtual surface identification file, which includes the surface identifier and the surface material identifier of the virtual surface.

[0177] 1103. Determining Coordinate Information: The computer device exports a static spatial file, which includes a virtual surface and virtual objects in the virtual space without rendered materials. The computer device loads this static spatial file using PhysX (a physics engine) to obtain the virtual space, and controls a collision box to move within this virtual space. Whenever the collision box collides with any element, the coordinate information of the area where the collision box is located is determined. This coordinate information can be used to indicate the area where the element that collided with the collision box is located.

[0178] 1104. Associate coordinate information and surface material identifiers and write them into the spatial description file: After the computer device obtains the coordinate information, it queries the element identifiers corresponding to the elements in the area indicated by the coordinate information. The element identifiers are either surface identifiers or object identifiers. In the identifier file generated in steps 1101 and 1102 above, the computer device queries the surface material identifiers corresponding to the element identifiers and associates the queried surface material identifiers with the coordinate information and writes them into the spatial description file.

[0179] The terrain type identification method provided in this application can be applied to any scenario where the terrain type of a region in a virtual space is identified. For example, in the context of a video game, the virtual space is a virtual space within the video game. The following description uses a video game as an example to illustrate the application scenario of this application.

[0180] In video games, a vast game world is created for the user; this game world, also known as the virtual space in this embodiment, allows the user to explore and freely choose when and how to complete game tasks. Users can also interact with elements within the game world, such as chopping down trees, building houses, harvesting crops, making fire, and cooking. To enhance the fun of video games, the method provided in this embodiment can be used to identify the terrain type of areas within the virtual space, thereby refreshing and controlling elements within the virtual space based on the terrain type.

[0181] For example, this application embodiment is applied to scenarios where collectibles are refreshed in a virtual space. In video games, players control virtual objects to perform activities in a virtual space, such as collecting virtual plants or picking up virtual items. To enhance the fun of video games, virtual plants can be randomly refreshed in the virtual space, such as virtual strawberries in a grassy area, virtual watermelons in a sandy area, and virtual lotus flowers in a lake. Therefore, the method provided in this application embodiment can be used to identify the terrain type of a region in the virtual space and refresh virtual plants that match the terrain type of that region.

[0182] For example, embodiments of this application are applied to scenarios where artificial intelligence (AI) objects are controlled to move within a virtual space. In video games, AI objects are controlled to move within an environment suitable for their survival. For instance, if an AI object's attribute is a penguin, it is controlled to move in snowy terrain within the virtual space; if its attribute is a monkey, it is controlled to move in a forest within the virtual space. Therefore, the method provided in embodiments of this application can be used to identify the terrain type of a region in the virtual space and control the movement of AI objects matching that terrain type within that region.

[0183] For example, this application embodiment is applied to scenarios where elements are refreshed based on environmental conditions in a virtual space. In video games, virtual space can also be used to simulate real environments under different conditions, such as sunny days, rainy days, foggy days, or nighttime. Computer devices can refresh elements in the virtual space under target environmental conditions. For example, when the target environmental condition is rainy, moss-like plants can be refreshed on rocks; when the target environmental condition is nighttime, bioluminescent insects such as fireflies can be refreshed in the forest. Therefore, the method provided in this application embodiment can be used to identify areas in the virtual space that belong to rocks or forests, thereby refreshing the corresponding elements and making the virtual space more realistic and richer.

[0184] In addition, the method provided in this application can also be applied to scenarios involving the creation of virtual spaces. For example, video game developers create virtual spaces to serve as game worlds. Developers create virtual surfaces and virtual objects through a space creation interface displayed on a terminal, render materials for the virtual surfaces and virtual objects, and set the material names corresponding to the virtual surfaces and the original or additional material identifiers corresponding to the virtual objects in the space creation interface. Then, the virtual objects are placed on the virtual surfaces to form the virtual space. Subsequently, the method provided in this application can be used to identify the terrain type of each area within the virtual space.

[0185] Figure 12This is a schematic diagram of the structure of a terrain type identification device provided in an embodiment of this application. See also... Figure 12 The device includes:

[0186] Material determination module 1201 is used to determine the surface material of elements in the virtual space in response to material recognition instructions;

[0187] The material determination module 1201 is also used to control the movement of the collision box in the virtual space. When the collision box collides with an element, the area where the collision box is located is determined as the area where the element is located.

[0188] The material determination module 1201 is also used to determine the surface material of the element as the material corresponding to the area where the element is located;

[0189] The type determination module 1202 is configured to, in response to a first identification instruction carrying a first target area, determine a first target material corresponding to the first target area, and determine the terrain type to which the first target material belongs as the terrain type to which the first target area belongs; or,

[0190] The region determination module 1203 is used to respond to a second identification instruction carrying a target landform type, determine a second target material corresponding to the target landform type, and determine the region corresponding to the second target material as a region belonging to the target landform type.

[0191] The terrain type recognition device provided in this application determines the region where an element is located in a virtual space by controlling the movement of a collision box in that virtual space, and uses the surface material of the element in the virtual space as the material corresponding to the region where the element is located. Considering that the material corresponding to a region can reflect the terrain type to which that region belongs, it can be considered that the terrain type to which the region belongs is also the terrain type to which the material corresponding to that region belongs. Therefore, when it is necessary to identify the terrain type to which a certain region belongs, the terrain type to which the material corresponding to that region belongs can be determined as the terrain type to which that region belongs, or when it is necessary to identify a region belonging to a certain terrain type, the region corresponding to the material belonging to that terrain type can be determined as the region belonging to that terrain type. This provides an automatic method for identifying terrain types, eliminating the need for manual labeling, saving manpower and time, and improving the efficiency of terrain type recognition.

[0212] The third determining unit 1231 is used to control the collision box to move from the first boundary of the subspace to the second boundary of the subspace. Whenever the collision box collides with any element, the area where the collision box is located is determined as the area where the element is located.

[0213] The second boundary is opposite to the first boundary and has the same shape. The first boundary and the second boundary are parallel to the target direction. The cross-section of the collision box in the target direction is the same as the cross-section of the subspace in the target direction.

[0214] Optionally, see Figure 13 The first boundary is the top boundary of the subspace, the second boundary is the bottom boundary of the subspace, and the device further includes:

[0215] The generation module 1205 is used to generate indication information corresponding to the element whenever the collision box collides with any element, provided that the collision is not the first collision of the collision box in the subspace.
