Description

Technical Field

[0001] The present disclosure relates to the field of computer technologies, and in particular, to a method, apparatus, device, and storage medium for constructing a virtual object. Background Art

[0002] With the rapid development of science and technology, the application of three-dimensional (3D) image reconstruction has received increasing attention and emphasis in various industries. Currently, 3D image reconstruction has been widely applied in daily life and scientific research. In related technologies, multiple three-dimensional materials of object parts can be pre-generated for subsequent use. Generally, three-dimensional virtual materials corresponding to two-dimensional virtual materials are directly generated to facilitate the quick acquisition of three-dimensional virtual materials and the splicing of three-dimensional virtual materials corresponding to two-dimensional virtual materials when generating a three-dimensional virtual object. However, for such three-dimensional virtual materials directly obtained from two-dimensional virtual materials, when splicing human faces, since the transitions of the three-dimensional virtual materials corresponding to different object parts are abrupt at the splicing points, the resulting three-dimensional virtual object will have unnatural connections at the splicing points of each object part.

[0082] In order to enable those of ordinary skill in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0083] It should be noted that the terms "first", "second", etc. in the specification, claims and above-mentioned drawings of the present disclosure are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order different from those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0084] Please refer to Figure 1 , which shows a schematic diagram of the implementation environment provided by the embodiments of the present disclosure. The implementation environment may include: at least one target terminal 01 and at least one server 02. The at least one target terminal 01 and the at least one server 02 can communicate data through a network.

[0085] In an alternative embodiment, the target terminal 01 may be a client that provides a construction request for a three-dimensional virtual object to the server 02. And when the server 02 constructs a three-dimensional virtual object according to the construction request to obtain a target three-dimensional virtual object, the target terminal 01 may receive the target three-dimensional virtual object sent by the server 02 and display the target three-dimensional virtual object on the interface. Among them, the above-mentioned target terminal 01 may include, but is not limited to, types of electronic devices such as smart phones, desktop computers, tablet computers, laptop computers, smart speakers, digital assistants, augmented reality (AR) / virtual reality (VR) devices, and smart wearable devices. The operating systems running on the target terminal 01 may include, but are not limited to, Android system, IOS system, linux, windows, Unix, etc.

[0086] In an alternative embodiment, the server 02 may be a server that constructs a three-dimensional virtual object in response to a construction request for a three-dimensional virtual object sent by the target terminal 01 to obtain a target three-dimensional virtual object. Optionally, the server 02 may be 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 communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0087] In addition, it should be noted that Figure 1 What is shown is merely an application environment of the virtual object construction method provided by the present disclosure.

[0088] It should be noted that the following figure shows a possible step sequence, but in fact, it is not necessary to strictly follow this sequence. Some steps can be executed in parallel without depending on each other. The user information (including but not limited to user device information, user personal information, user behavior information, etc.) and data (including but not limited to data for display, training data, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties.

[0089] Figure 2 is a flowchart of a virtual object construction method shown according to an exemplary embodiment. This virtual object construction method can be applied to server 02, such as Figure 2 shown, the virtual object construction method includes the following steps:

[0090] In step S21, a construction request for a three-dimensional virtual object sent by the target terminal is received. The construction request includes material identifiers of a plurality of target two-dimensional materials.

[0091] In the embodiments of this specification, the three-dimensional virtual object can be any object. For example, it can include furniture, pets (dogs and cats), humans, etc. As an example, below, a part of the human body will be described, such as the head.

[0092] In the embodiments of this specification, the plurality of target two-dimensional materials can be at least two of a plurality of first preset two-dimensional materials; the plurality of first preset two-dimensional materials can be two-dimensional materials corresponding to the facial features of the head. The material identifier of the target two-dimensional material can be used to uniquely identify the target two-dimensional material to distinguish it from other first preset two-dimensional materials.

[0093] In practical applications, the target terminal can display a plurality of first preset two-dimensional materials. The user can select a plurality of target two-dimensional materials from the plurality of first preset two-dimensional materials. Based on the user's selection, the target terminal can be triggered to generate a construction request for a three-dimensional virtual object and send the construction request to the server. The server performs construction processing on the three-dimensional virtual object based on this construction request. Specifically, the construction request can include material identifiers of a plurality of target two-dimensional materials.

[0094] In step S22, a target three-dimensional material corresponding to the material identifier is determined from the first preset three-dimensional material set. The first preset three-dimensional materials in the first preset three-dimensional material set are obtained by performing three-dimensional conversion processing on a plurality of first preset two-dimensional virtual objects to obtain a plurality of first preset three-dimensional virtual objects and then performing segmentation processing on the plurality of first preset three-dimensional virtual objects.

[0095] In the embodiments of this specification, the first preset three-dimensional material set refers to a set composed of preset three-dimensional materials. There may be a corresponding relationship between the material identifiers of the preset two-dimensional materials and the material identifiers of the preset three-dimensional materials. Therefore, based on this corresponding relationship, the material identifier of the target three-dimensional material corresponding to the material identifier of the target two-dimensional material can be determined, and then the target three-dimensional material corresponding to the material identifier of the target three-dimensional material can be determined from the first preset three-dimensional material set. In some examples, the corresponding relationship between the material identifiers of the preset two-dimensional materials and the material identifiers of the preset three-dimensional materials may be as shown in the following table:

[0096] Table 1

[0097]

[0098] The example of the corresponding relationship between the material identifiers of the preset two-dimensional materials and the material identifiers of the preset three-dimensional materials shown in Table 1 above is only an example provided in the embodiments of this specification. The embodiments of this application do not limit the representation method of the material identifiers.

[0099] In the embodiments of this specification, the preset three-dimensional materials in the first preset three-dimensional material set are three-dimensional materials of preset object parts. For example, when the three-dimensional virtual object to be constructed is the head, the preset object parts can be the facial features of the head. Correspondingly, the first preset three-dimensional material set can include the three-dimensional materials corresponding to the facial features of the head. The preset object parts can include the eyebrow part, the eye part, the nose part, the mouth part, and the ear part. The first preset two-dimensional virtual object can be a two-dimensional head image.

[0100] In the embodiments of this specification, the segmentation process for multiple preset three-dimensional virtual objects can be to, after performing three-dimensional conversion on multiple preset two-dimensional virtual objects to obtain multiple preset three-dimensional virtual objects, split out the corresponding preset three-dimensional materials according to the annotations of the vertices of the preset object parts.

[0101] In step S23, the multiple target three-dimensional materials are spliced to obtain a target three-dimensional virtual object.

[0102] In the embodiments of this specification, the target three-dimensional virtual object refers to a three-dimensional virtual object constructed according to the construction request of the three-dimensional virtual object sent by the target terminal. The preset object parts can include multiple object parts. According to the multiple vertices of each object part, the target three-dimensional materials are spliced to obtain the target three-dimensional virtual object. Among them, the multiple vertices of each object part can refer to multiple points on the edge of each object part. For example, when the target three-dimensional virtual object is the head, the target three-dimensional materials can be spliced according to the annotations of the vertices of the five parts including the eyebrows, eyes, nose, mouth, and ears; when the target three-dimensional virtual object is the human body, the target three-dimensional materials can be spliced according to the annotations of the vertices of the three parts including the head, limbs, and torso.

[0103] Specifically, the annotation of the vertices of different preset object parts during splicing can be correlated. For example, the annotation of the vertices of the eyebrow and eye parts is correlated. Based on this correlation, the target 3D materials of the eyebrow and eye parts can be spliced.

[0104] Optionally, in order to avoid obvious protrusions or corners during the splicing process, when annotating the preset 3D material, the annotated points can be extended outward by a target distance after splitting the preset 3D material, so as to ensure that the splicing process of the multiple target 3D materials is smoother.

[0105] In step S24, the target 3D virtual object is sent to the target terminal.

[0106] In the embodiments of this specification, the target 3D virtual object can be sent to the target terminal through the network, so that the target terminal can display the target 3D virtual object, or the target terminal can perform business processing on the received target 3D virtual object.

[0107] By performing 3D conversion processing on multiple first preset 2D virtual objects in advance, multiple first preset 3D virtual objects are obtained, and by performing segmentation processing on the multiple first preset 3D virtual objects, a first preset 3D material set including multiple first preset 3D materials can be obtained. For the 3D virtual object obtained by converting a complete 2D virtual object, in the case of using it for material segmentation processing to obtain 3D materials, it can ensure that the splicing process of the 3D materials is smoother and the connection at the splicing is more natural; moreover, by the method of sending a construction request by the target terminal to obtain the target 3D virtual object, users can achieve personalized customization of each object part of the 3D virtual object and obtain a target 3D virtual object with smooth splicing of each object part.

[0108] In an exemplary embodiment, as Figure 3 shown, the method may further include:

[0109] In step S31, multiple first preset 2D virtual objects are obtained.

[0110] In the embodiments of this specification, the multiple first preset 2D virtual objects refer to the 2D virtual objects corresponding to the preset object parts. Since the first preset 2D virtual object in the embodiments of this specification is a whole and the transition at the connection of different object parts is smooth, it can make the transition at the connection of different preset object parts of the preset 3D virtual object obtained by subsequent 3D conversion processing based on the preset 2D virtual object also smooth.

[0111] In the embodiments of this specification, multiple first preset two-dimensional virtual objects can be obtained by drawing. For example, the first preset two-dimensional virtual object can be a two-dimensional head picture, which can be drawn by a drawing engineer in a drawing application. Obtaining multiple preset two-dimensional virtual objects by drawing can reduce the defects of the preset two-dimensional virtual objects.

[0112] In step S32, three-dimensional conversion processing is performed on multiple first preset two-dimensional virtual objects to obtain multiple first preset three-dimensional virtual objects.

[0113] In the embodiments of this specification, when performing three-dimensional conversion processing on multiple first preset two-dimensional virtual objects, a three-dimensional general model can be preset. Texture mapping processing is performed on the three-dimensional general model according to multiple first preset two-dimensional virtual objects respectively to obtain multiple first preset three-dimensional virtual objects. Taking the texture mapping processing of the three-dimensional general model according to a first preset two-dimensional virtual object as an example, the preset object parts of the first preset two-dimensional virtual object can be corresponded to the preset object parts of the three-dimensional general model, and the texture map of the first preset two-dimensional virtual object is covered on the three-dimensional general model to simulate the concavity and convexity and shape and other characteristics of each preset object part of the first preset three-dimensional virtual object, so as to generate the corresponding preset three-dimensional virtual object of the first preset two-dimensional virtual object.

[0114] In step S33, based on the preset object parts, segmentation processing is performed on multiple first preset three-dimensional virtual objects to obtain a first preset three-dimensional material set.

[0115] In the embodiments of this specification, the topology and vertices of the three-dimensional general model can be set according to the preset object parts to obtain the corresponding annotations for the preset object parts, so that when performing segmentation processing on multiple first preset three-dimensional virtual objects, the corresponding multiple first preset three-dimensional materials can be directly split according to the annotations. Specifically, the topology of the three-dimensional general model represents the point-line-plane layout, structure, and connection situation of the three-dimensional general model in the form of a polygon mesh. After performing segmentation processing on multiple first preset three-dimensional virtual objects, the full amount of first preset three-dimensional materials corresponding to the multiple first preset three-dimensional virtual objects can be obtained, and the full amount of first preset three-dimensional materials is used as the first preset three-dimensional material set.

[0116] Optionally, the process of segmenting multiple preset three-dimensional virtual objects to obtain a preset three-dimensional material set may include: determining three-dimensional blend deformation materials corresponding to different preset object parts in the three-dimensional virtual object based on the preset object parts, and using the three-dimensional blend deformation materials as three-dimensional materials. In the embodiments of this specification, when segmenting each preset three-dimensional virtual object, each preset object part can be independently stored in a general model in the form of BS (Blend Shape, three-dimensional blend deformation). This enables the fusion of three-dimensional blend deformation files when combining preset three-dimensional materials of different preset object parts.

[0117] By determining three-dimensional blend deformation materials corresponding to different preset object parts in the three-dimensional virtual object based on the preset object parts, and using the three-dimensional blend deformation materials as three-dimensional materials, the convenience of subsequent combination of three-dimensional materials can be improved.

[0118] By obtaining multiple complete first preset two-dimensional virtual objects, performing three-dimensional conversion processing on the multiple first preset two-dimensional virtual objects to obtain multiple first preset three-dimensional virtual objects, and based on the preset object parts, performing segmentation processing on the multiple first preset three-dimensional virtual objects to obtain a first preset three-dimensional material set. Since the first preset two-dimensional virtual objects themselves are complete, the object parts of the obtained first preset three-dimensional virtual objects are smoothly and naturally connected. Splitting the different object parts of the first preset three-dimensional virtual object can obtain preset three-dimensional materials for users to make personalized selections.

[0119] In some exemplary embodiments, as Figure 4 shown, before obtaining multiple preset two-dimensional virtual objects, the method may further include:

[0120] In step S41, obtaining multiple first preset two-dimensional materials, where the multiple first preset two-dimensional materials are two-dimensional materials corresponding to the preset object parts.

[0121] In the embodiments of the present specification, multiple first preset two-dimensional materials may be layer files of a first preset two-dimensional virtual object drawn by a drawing engineer. During the drawing process, at least one object part may be drawn on one layer first, and then other object parts may be drawn on other layers. Subsequently, all the layers are superimposed to obtain a complete first preset two-dimensional virtual object. Based on this, the materials corresponding to different object parts are superimposed, and the obtained two-dimensional virtual objects can be smoothly connected without being obtrusive at the joints of different preset object parts. It should be noted that when all the layers are superimposed to obtain a complete first preset two-dimensional virtual object, the positions of the object parts in each layer are precisely adjusted, which can ensure that the first preset two-dimensional materials corresponding to the preset object parts on different layers are in the appropriate positions of the first preset two-dimensional virtual object, thereby ensuring the integrity of the first preset virtual object and the coordination of each object part.

[0122] In step S42, according to the object parts of multiple first preset two-dimensional materials, the multiple first preset two-dimensional materials are divided into multiple first material combinations, and each first material combination includes the first preset two-dimensional materials corresponding to the preset object parts.

[0123] In the embodiments of the present specification, each first material combination is a combination of the first preset two-dimensional materials corresponding to the preset object parts. For example Figure 5 as shown Figure 5 (a) are multiple face shape materials, Figure 5 (b) are multiple mouth materials, Figure 5 (c) are multiple eyebrow materials, Figure 5 (d) are multiple eye materials, that is, the multiple preset two-dimensional materials are face shape 1, face shape 2... face shape 6, mouth 1, mouth 2... mouth 6, eyebrow 1, eyebrow 2... eyebrow 6, eye 1, eye 2... eye 6. According to the preset object parts, multiple first material combinations are determined. The multiple first material combinations may be as shown in the following table:

[0124] Table 2

[0125]

[0126]

[0127] The above Table 2 only shows a possible example of multiple first material combinations provided by the embodiments of the present specification. The embodiments of the present application do not limit whether the first material combinations are unique or the expression methods of the content in the first material combination set.

[0128] In step S43, material combination processing is performed on the first preset two-dimensional materials in each first material combination to obtain multiple first preset two-dimensional virtual objects.

[0129] In the embodiments of this specification, the first preset two-dimensional materials in each first material combination can be stored in the form of layers. All the layers in each first material combination can be superimposed to obtain the first preset two-dimensional virtual object corresponding to each first material combination. Taking the head facial features as an example of the preset object part, each first material combination can include five layers corresponding to the head facial features, so that the five layers can be superimposed to obtain the first preset two-dimensional virtual object, such as Figure 6 shown.

[0130] By obtaining a plurality of first preset two-dimensional materials and dividing the plurality of first preset two-dimensional materials into a plurality of first material combinations according to the object parts of the plurality of first preset two-dimensional materials, it is possible to ensure that each first preset two-dimensional material is considered when constructing the first preset two-dimensional virtual object, and it is possible to avoid the repeated use of the first preset two-dimensional materials by random combination; and perform material combination processing on the first preset two-dimensional materials in each first material combination to obtain a plurality of first preset two-dimensional virtual objects, which improves the processing efficiency of the conversion process from the first preset two-dimensional materials to the first preset two-dimensional virtual objects and reduces the conversion processing amount.

[0131] In some exemplary embodiments, as Figure 7 shown, performing combination processing on the first preset two-dimensional materials in each first material combination to obtain a plurality of first preset two-dimensional virtual objects may include:

[0132] In step S71, determine the object part and position information corresponding to the first preset two-dimensional materials in each first material combination.

[0133] In the embodiments of this specification, the first preset two-dimensional materials can carry object part information and position information. For example, when the preset two-dimensional material is a layer file, the object part information and position information can be stored in the hierarchical file of the first preset two-dimensional material in advance by means of annotation, and the object part and position information corresponding to the first preset two-dimensional material can be determined by obtaining the annotation information.

[0134] In step S72, based on the object part and position information of the first preset two-dimensional materials in each first material combination, perform hierarchical superposition processing and position adjustment on the first preset two-dimensional materials in each first material combination to obtain the two-dimensional virtual object corresponding to each first material combination.

[0135] In the embodiments of this specification, the first preset two-dimensional materials in each first material combination can be subjected to hierarchical superposition processing according to the preset object part to ensure the integrity of the preset object part of the two-dimensional virtual object, and the position of the preset two-dimensional materials in each first material combination can be adjusted according to the position information, so that the overall two-dimensional virtual object composed of different preset object parts is natural and coordinated.

[0136] By determining the object parts and position information corresponding to the first preset two-dimensional materials in each first material combination, and based on the object parts and position information of the first preset two-dimensional materials in each first material combination, performing hierarchical superposition processing and position adjustment on the first preset two-dimensional materials in each material combination, a first preset two-dimensional virtual object corresponding to each material combination can be obtained, which can ensure the integrity and overall natural coordination of the first preset two-dimensional virtual object.

[0137] In some exemplary embodiments, the preset three-dimensional material set can be updated. Based on this, as Figure 8 shown, the method may further include:

[0138] In step S81, receive an update request for the preset three-dimensional material, where the update request includes a second preset two-dimensional material.

[0139] In the embodiments of this specification, there is a corresponding first preset two-dimensional material for each first preset three-dimensional material in the first preset three-dimensional material set, and the second preset two-dimensional material is a material other than the first preset two-dimensional material. The second preset two-dimensional material can be obtained from another terminal or automatically generated. It can be two-dimensional materials corresponding to all preset object parts that form an overall two-dimensional virtual object, or two-dimensional materials corresponding to some object parts in the preset object parts. The present disclosure does not limit this.

[0140] In step S82, based on the second preset two-dimensional material, construct a second preset two-dimensional virtual object.

[0141] In the embodiments of this specification, the two-dimensional materials that make up the second preset two-dimensional virtual object include at least one second preset two-dimensional material. Specifically, the second preset two-dimensional materials can be spliced to obtain the second preset two-dimensional virtual object.

[0142] In step S83, perform three-dimensional conversion processing on the second preset two-dimensional virtual object to obtain a second preset three-dimensional virtual object.

[0143] In the embodiments of this specification, the texture map of the second preset two-dimensional virtual object can be covered on a preset three-dimensional general model to simulate the concave-convex feeling and shape and other characteristics of each preset object part of the second preset three-dimensional virtual object, so as to obtain the second preset three-dimensional virtual object.

[0144] In step S84, based on the preset object parts, perform segmentation processing on the second preset three-dimensional virtual object to obtain a second preset three-dimensional material set.

[0145] In the embodiments of this specification, based on a preset object part, the topology and vertex semantics of the three-dimensional general model can be set to fixed semantics to obtain an annotation corresponding to the preset object part. In this way, when performing segmentation processing on the second preset three-dimensional virtual object, the second preset three-dimensional materials can be directly split according to the annotation, and thus the second preset three-dimensional material set can be obtained.

[0146] In step S85, the first preset three-dimensional material set is updated based on the second preset three-dimensional material set to obtain an updated preset three-dimensional material set.

[0147] In the embodiments of this specification, after obtaining the second preset three-dimensional material set, the first preset three-dimensional material set and the second preset three-dimensional material set can be merged, and the merged material set is the updated preset three-dimensional material set. It should be noted that after obtaining the updated preset three-dimensional material set, the target terminal will display the updated preset two-dimensional material set for the user to select. There is a one-to-one correspondence between the preset two-dimensional materials in the updated preset two-dimensional material set and the preset three-dimensional materials in the updated preset three-dimensional material set. The server can determine the target three-dimensional material corresponding to the target two-dimensional material selected by the user based on this correspondence relationship to construct the target three-dimensional virtual object.

[0148] By receiving an update request for the preset three-dimensional materials, the update request includes the second preset two-dimensional materials, constructing the second preset two-dimensional virtual object based on the second preset two-dimensional materials, performing three-dimensional conversion processing on the second preset two-dimensional virtual object to obtain the second preset three-dimensional virtual object, performing segmentation processing on the second preset three-dimensional virtual object based on the preset object part to obtain the second preset three-dimensional material set, and updating the first preset three-dimensional material set based on the second preset three-dimensional material set to obtain the updated preset three-dimensional material set, it is possible to update the preset three-dimensional material set based on the second preset two-dimensional materials, simplify the update processing flow of the preset three-dimensional material set, and improve the update efficiency.

[0149] In some exemplary embodiments, such as Figure 9 shown, constructing the second preset two-dimensional virtual object based on the second preset two-dimensional materials may include:

[0150] In step S91, when the object part corresponding to the second preset two-dimensional material is all the object parts of the preset object part, the second preset two-dimensional material is divided to obtain a plurality of second material combinations.

[0151] In the embodiments of this specification, the second preset two-dimensional materials can be combined and divided according to the preset object part. Specifically, a plurality of second preset two-dimensional materials corresponding to the preset object part that have not appeared in other combinations can be used as one combination. Based on this, the second preset two-dimensional materials in each of the obtained second material combinations do not repeat.

[0152] In step S92, perform a combination process on the second preset two-dimensional materials in each second material combination to obtain a second preset two-dimensional virtual object.

[0153] By dividing the second preset two-dimensional material to obtain a plurality of second material combinations when the object part corresponding to the second preset two-dimensional material is all the object parts of the preset object part, and performing a combination process on the second preset two-dimensional materials in each second material combination to obtain a second preset two-dimensional virtual object, the number of second material combinations can be minimized, the utilization rate of the second preset two-dimensional materials can be improved, and the combination efficiency can be improved.

[0154] In some exemplary embodiments, as Figure 10 shown, constructing a second preset two-dimensional virtual object based on the second preset two-dimensional material may include:

[0155] In step S101, when the object part corresponding to the second preset two-dimensional material is part of the preset object part, determine the first object part of the second preset two-dimensional material.

[0156] In the embodiments of this specification, when the second preset two-dimensional material is a layer file, the preset object part of the new two-dimensional material can be determined according to the layer where the second preset two-dimensional material is located. When some second preset two-dimensional materials carry annotation information, the first object part of the second preset two-dimensional material can be determined according to the annotation information.

[0157] In step S102, based on the first object part of the second preset two-dimensional material, determine a second object part, where the second object part is the object part of the preset object part other than the first object part.

[0158] In the embodiments of this specification, the second object part is an object part different from the first object part, and the second object part and the first object part can form the preset object part. Taking the head as an example, the preset object part is eyebrows, eyes, nose, mouth, ears. If the first object part includes eyebrows and eyes, then the second object part can be nose, mouth, ears.

[0159] In step S103, obtain the first preset two-dimensional material corresponding to the second object part from a plurality of first preset two-dimensional materials.

[0160] In the embodiments of this specification, obtaining the first preset two-dimensional material corresponding to the second object part from multiple first preset two-dimensional materials may be obtaining a fixed number of first preset two-dimensional materials or first preset two-dimensional materials with fixed material identifiers. Specifically, for each object part in the second object part, one corresponding first preset two-dimensional material can be obtained from multiple first preset two-dimensional materials. For example, among the second preset two-dimensional materials corresponding to the first object part, there are two eyebrow materials and two eye materials, and one nose material, one mouth material, and one ear material can be obtained from multiple first preset two-dimensional materials, so that the nose material, mouth material, and ear material can be combined with the second preset two-dimensional materials corresponding to the first object part subsequently.

[0161] In step S104, multiple third material combinations are determined according to the second preset two-dimensional materials corresponding to the first object part and the first preset two-dimensional materials corresponding to the second object part.

[0162] In the embodiments of this specification, the second preset two-dimensional materials corresponding to the first object part and the first preset two-dimensional materials corresponding to the second object part are combined according to the preset object parts to obtain multiple third material combinations.

[0163] In step S105, the second preset two-dimensional materials and the first preset two-dimensional materials corresponding to the second object part in each third material combination are combined to obtain a second preset two-dimensional virtual object.

[0164] By determining the first object part of the second preset two-dimensional material when the object part corresponding to the second preset two-dimensional material is a partial object part in the preset object parts, determining the second object part based on the first object part of the second preset two-dimensional material, obtaining the first preset two-dimensional material corresponding to the second object part from multiple first preset two-dimensional materials, and determining multiple third material combinations according to the second preset two-dimensional materials corresponding to the first object part and the first preset two-dimensional materials corresponding to the second object part, it is possible to quickly and efficiently determine the third material combinations when the object part corresponding to the second preset two-dimensional material is a partial object part in the preset object parts, so as to prepare for updating the first preset three-dimensional material set subsequently.
