[0016] Embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While several embodiments of the present disclosure are illustrated, it is to be understood that the present disclosure is not to be limited to the precise embodiments and that various changes and modifications can be effected therein by one skilled in the art. It should be understood that the drawings and detailed description thereto are not intended to limit the scope of the present disclosure to the precise embodiments illustrated. Rather, the embodiments are intended to illustrate by way of example the various aspects of the present disclosure.

[0017] It should be noted that the headings provided in any section / subsection of the disclosure herein are not limitations. Various embodiments are described throughout this document and any type of embodiment can be included under any section / subsection. Furthermore, embodiments described in any section / subsection can be combined with any other embodiment described in the same section / subsection and / or a different section / subsection in any manner.

[0018] In the description of embodiments of the disclosure, the term "includes" and its derivatives, such as "including," should be understood in an open-ended way, that is, "including but not limited to." The term "based on" should be understood as "based at least in part on." The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment." The term "some embodiments" should be understood as "at least some embodiments." Other explicit and implicit definitions can also be included below. The terms "first," "second," and the like can refer to different or the same objects. Other explicit and implicit definitions can also be included below.

[0019] Data of users, acquisition and / or use of data, etc. can be involved in embodiments of the disclosure. These aspects all comply with corresponding laws and regulations and relevant provisions. In embodiments of the disclosure, all data collection, acquisition, processing, processing, forwarding, use, etc. are carried out on the premise that the user is aware of and confirms. Accordingly, when implementing embodiments of the disclosure, the type of data or information that can be involved, the use range, the use scenario, etc. should be notified to the user and the authorization of the user should be obtained through appropriate means according to relevant laws and regulations. The specific notification and / or authorization mode can vary according to the actual situation and application scenario, and the scope of the disclosure is not limited in this respect.

[0020] In the specification and embodiments of the disclosure, if personal information processing is involved, it will be processed on the premise of legality (for example, obtaining the consent of the subject of personal information, or being necessary for the performance of a contract, etc.), and only within the prescribed or agreed range. Users refuse to process personal information other than the necessary information required for basic functions, which will not affect the user's use of basic functions.

[0021] As briefly mentioned above, some complex virtual scenes can involve multiple texture elements. In addition, in the production of some large virtual scenes, different regions can be produced by different designers, and splicing for different regions is performed. This can cause obvious seams when splicing textures.

[0022] For example, Figure 1An example map 100 generated according to a conventional scheme is shown. In the example map 100, the textures of two adjacent map regions 110 and 120 may, for example, be made by different designers, which results in an obvious seam 130 when the two adjacent map regions 110 and 120 are spliced. This will greatly affect the interactive experience of the user, which is undesirable.

[0023] Embodiments of the present disclosure propose a scheme for map processing. According to various embodiments of the present disclosure, an electronic device can determine a transition region associated with a first map region and a second map region. Further, the electronic device can determine a set of private textures based on first texture information of the first map region and second texture information of the second map region, where the set of private textures includes a first set of private textures corresponding to the first map region and / or a second set of private textures corresponding to the second map region.

[0024] Correspondingly, by removing the set of private textures from the transition region, the electronic device can determine a to-be-filled region in the transition region, and can fill the to-be-filled region with the first texture information and the second texture information.

[0025] In this way, embodiments of the present disclosure can achieve smooth transition of textures between different map regions by eliminating private textures in map regions from the transition region and performing re-filling of textures, thereby improving the interactive experience of the user.

[0026] Various example implementations of the scheme are described in further detail below in conjunction with the accompanying drawings. Embodiments of the present disclosure can be applied in various fields of games, simulations, simulations, virtual reality, augmented reality, etc.

[0027] Example Environment

[0028] Figure 2 A schematic diagram of an example environment 200 in which embodiments of the present disclosure can be implemented is shown. As shown, the example environment 200 can include an electronic device 230. Figure 2

[0029] ​In some embodiments, electronic device 230 may be any type of mobile terminal, fixed terminal, or portable terminal, including mobile phones, desktop computers, laptop computers, notebook computers, netbook computers, tablet computers, media computers, multimedia tablets, handheld computers, portable gaming terminals, VR / AR devices, personal communication system (PCS) devices, personal navigation devices, personal digital assistants (PDAs), audio / video players, digital cameras / camcorders, positioning devices, television receivers, radio receivers, e-book devices, gaming devices, or any combination thereof, including accessories and peripherals of these devices or any combination thereof. In some embodiments, electronic device 230 may also include computing systems / servers, such as mainframes, edge computing nodes, computing devices in cloud environments, etc.

[0030] like Figure 2 As shown, the electronic device 230 can acquire first texture information corresponding to the first map region 210 and second texture information corresponding to the second map region 220. Such first map region 210 and second map region 220 can be, for example, adjacent regions in a virtual scene.

[0031] In this disclosure, textures can represent appropriate objects used to construct virtual scenes, such as grasslands, deserts, water bodies, snow-capped mountains, etc. Different objects can correspond to different textures, for example.

[0032] In some embodiments, the first map region 210 and the second map region 220 may be, for example, adjacent surface regions in a virtual scene (also referred to as map regions in some scenarios). Such surface regions may be used to represent the surface environment in a virtual scene.

[0033] As will be described in detail below, the electronic device 230 can perform transition processing on the texture information of the first map region 210 and the second map region 220. In some embodiments, the electronic device 230 may also generate a surface image 240 corresponding to the first map region 210 and the second map region 220 based on the transitioned texture information.

[0034] Such a surface image 240 can be applied to any suitable application, such as gaming applications, simulation applications, and so on. This disclosure is not intended to be limiting.

[0035] The following description will continue with reference to the accompanying drawings, which will provide some exemplary embodiments of this disclosure.

[0036] Example Process

[0037] Figure 3 A flowchart of a process 300 for map processing according to some embodiments of the present disclosure is shown. The process 300 can be implemented at an electronic device 230 as shown in Figure 2 For ease of discussion, the process 300 will be described with reference to the environment 200. Figure 2

[0038] At block 310, the electronic device 230 determines a transition region associated with the first map region and the second map region.

[0039] The specific process of block 310 will be described below with reference to Figure 4A Figure 4A A schematic diagram 400A of map processing according to some embodiments of the present disclosure is shown.

[0040] As shown in Figure 4A For adjacent first map region 405 and second map region 410, the electronic device 230 can determine a transition region 415 based on the positional relationship of the two regions.

[0041] In some embodiments, the electronic device 230 can determine the transition region 415 by utilizing a noise generation algorithm. Specifically, the electronic device 230 determines a target noise generation algorithm from a set of pre-set noise generation algorithms. Illustratively, the electronic device 230 can provide a set of selectable noise generation algorithms, examples of which can include but are not limited to: Berlin noise generation algorithm, Worley noise generation algorithm, grid noise generation algorithm, etc.

[0042] Further, the electronic device 230 can generate the transition region 415 associated with the first map region 405 and the second map region 410 according to the selected target noise generation algorithm.

[0043] Illustratively, the electronic device 230 can perform a plurality of noise generation processes according to the Berlin noise generation algorithm, thereby determining the transition region 415. Such transition region 415 can be represented, for example, by way of a mask.

[0044] In some embodiments, the electronic device 230 can also determine, for example, a range in which the noise region is generated, for example, a range to the boundary of the first map region 405 and the second map region 410, and ensure that the transition region 415 is always within the range. Illustratively, such range can be specified by a user, for example.

[0045] Continuing with reference to Figure 3 ​​At block 320, the electronic device 230 determines a set of private textures based on the first texture information of the first map region and the second texture information of the second map region, the set of private textures including a first set of private textures corresponding to the first map region and / or a second set of private textures corresponding to the second map region.

[0046] Continuing Figure 4A For example, the electronic device 230 can perform statistics on the first texture information of the first map region 405 and the second texture information of the second map region 410, and accordingly can divide the textures into two types: public textures and private textures.

[0047] The public textures represent textures that are contained in both the first map region 405 and the second map region 410. For example, if the first map region 405 and the second map region 410 can both include a desert texture, the desert texture can be determined as a public texture of the first map region 405 and the second map region 410.

[0048] The private textures are textures corresponding to a certain region. For example, if only the first map region 405 includes a forest, the forest texture can be determined as a private texture of the first map region 405. If only the second map region 410 includes a snowfield, the snowfield texture can be determined as a private texture of the second map region 410.

[0049] Thus, the electronic device 230 can determine a set of private textures. It should be understood that the first map region 405 and the second map region 410 can both have their corresponding private textures, or one of the regions can not have any private textures.

[0050] Continuing to refer to Figure 3 At block 330, the electronic device 230 determines a region to be filled in the transition region by removing the set of private textures from the transition region.

[0051] In some embodiments, after determining the set of private textures, the electronic device 230 can remove the set of private textures from the transition region. For example, Figure 4A For example, if the forest texture is determined as a private texture of the first map region 405, and the snowfield texture can be determined as a private texture of the second map region 410, the electronic device 230 can remove the voxels corresponding to the forest texture and the snowfield texture from the transition region 415.

[0052] Further, the electronic device 230 can determine a region in the transition region 415 where no texture exists, and thus determine it as a region to be filled. For example, Figure 4B An example of a region to be filled 400B is shown, according to some embodiments of the present disclosure, where the black part represents the position of the texture to be filled.

[0053] With reference to both Figure 3 At block 340, the electronic device 230 fills the to-be-filled region with the first texture information and the second texture information.

[0054] In some embodiments, the electronic device 230 may, for example, determine one or more textures for filling the to-be-filled region with the first texture information and the second texture information. For example, the electronic device 230 may, for example, fill such a to-be-filled region with a common texture corresponding to the most voxels in the first map region and the second map region.

[0055] In some embodiments, the electronic device 230 may, for example, also perform a more fine-grained texture filling. Specifically, as Figure 4B illustrated, the electronic device 230 may, for example, determine a plurality of reference regions 420 associated with the transition region 415, such a plurality of reference regions 420 may, for example, have a preset shape, e.g., a rectangle, a square, a triangle, etc.

[0056] In some embodiments, such a plurality of reference regions 420 may, for example, be determined based on a partitioning of the region restricted for noise generation as discussed above.

[0057] Further, for such a reference region 420, the electronic device 230 may, for example, perform a region-level texture analysis and filling. For example, Figure 4B As an example, the electronic device 230 may, for example, first determine whether the first portion 422 and the second portion 424 of the reference region 420 include a region common texture, i.e., have the same texture. As Figure 4B illustrated, the first portion 422 may, for example, correspond to the first map region 405, and the second portion 424 may, for example, correspond to the second map region 410.

[0058] If it is determined that the first portion 422 and the second portion 424 include a region common texture, the electronic device 230 may, for example, fill the to-be-filled portion in the reference region 420 with the region common texture, such a to-be-filled portion may, for example, be determined based on the to-be-filled region.

[0059] For example, if the first portion 422 and the second portion 424 both have a desert texture, the electronic device 230 may, for example, fill the to-be-filled portion in the reference region 420 with the desert texture.

[0060] In some embodiments, if the first portion 422 and the second portion 424 include a plurality of region common textures, the electronic device 230 may, for example, determine a target region common texture having the most voxels in the target reference region from the plurality of region common textures.

[0061] For example, if the first portion 422 and the second portion 424 both include a desert texture and a grass texture, the electronic device 230 can determine the texture (e.g., the desert texture) having more voxels in the reference region 420 as the target region common texture.

[0062] Further, the electronic device 230 can fill the portion to be filled in the reference region 420 with the target region common texture.

[0063] In some embodiments, if the first portion 422 and the second portion 424 do not include any region common texture, the electronic device 230 can determine a set of global common textures of the first map region 405 and the second map region 410.

[0064] Further, the electronic device 230 can determine a target global common texture having the most voxels in the first map region 405 and the second map region 410 from the set of global common textures. For example, if the first map region 405 and the second map region 410 include a plurality of global common textures, and the desert texture is the texture having the most voxels in the first map region 405 and the second map region 410 from the plurality of global common textures, the electronic device 230 can determine the desert texture as the target global common texture.

[0065] Further, the electronic device 230 can fill the portion to be filled in the target reference region with the determined target global common texture.

[0066] Based on such a manner, embodiments of the present disclosure can further improve the fineness of the texture transition processing, and improve the interactive experience of the user.

[0067] For example, the texture result filled based on the above-discussed process can be as shown in Figure 4C As shown in Figure 4C Embodiments of the present disclosure can improve the realism of the texture transition.

[0068] However, in some cases, there can be a jump in the filled textures used by two adjacent regions, and thus some seams can still be generated between different reference regions. To further avoid the generation of seams between reference regions, the electronic device 230 can further perform a further texture transition processing between different reference regions.

[0069] In some embodiments, the electronic device 230 can perform a transition processing on two adjacent map regions with texture jumps. As shown in Figure 4D In some embodiments, the electronic device 230 can perform a transition processing on two adjacent map regions with texture jumps. As shown in

[0070] For example, the first reference region 430 can be filled with a desert texture, and the second reference region 440 can be filled with a grass texture. Thus, due to the abrupt change of the filling textures, a seam 435 can be generated between the first reference region 430 and the second reference region 440.

[0071] Further, as shown in FIG. 2B, the electronic device 230 can determine a first update region 450 associated with the first reference region 430 and the second reference region 440. Similar to the generation of the transition region 415, the electronic device 230 can determine the first update region 450 by using a preset noise generation algorithm, for example. Figure 4D Accordingly, the electronic device 230 can determine a target common texture having the most voxels in the first reference region 430 and the second reference region 440.

[0072] For example, the first reference region 430 and the second reference region 440 can include multiple common textures, and the texture corresponding to the most voxels can be a desert texture. Thus, as shown in FIG. 2C, the electronic device 230 can fill the first update region 450 with the desert texture, i.e., replace the part of the first update region 450 previously filled with the common texture with the desert texture. Thus, embodiments of the present disclosure can avoid the generation of seams between different reference regions due to texture filling.

[0073] Figure 4D In some embodiments, the electronic device 230 can also avoid using the same texture to fill multiple reference regions continuously.

[0074] Specifically, the electronic device 230 can determine a set of reference regions in the multiple reference regions 420 that are continuous in position, wherein the set of reference regions are filled with the same third texture, and the number of the set of reference regions is greater than a threshold number.

[0075] For example, the electronic device 230 can determine that there are more than three reference regions 420 that are continuous in position and filled with the same texture in the lateral direction. Accordingly, the electronic device 230 can perform further map processing on such reference regions.

[0076] Specifically, the electronic device 230 can determine a second update region associated with the set of reference regions. For example, the electronic device 230 can determine a third reference region and a fourth reference region from the set of reference regions based on the positions of the set of reference regions. For example, the electronic device 230 can determine the last two position-adjacent reference regions as the third reference region and the fourth reference region according to the filling order.

[0077] Specifically, the electronic device 230 can determine a second update region associated with the set of reference regions. For example, the electronic device 230 can determine a third reference region and a fourth reference region from the set of reference regions based on the positions of the set of reference regions. For example, the electronic device 230 can determine the last two position-adjacent reference regions as the third reference region and the fourth reference region according to the filling order. ​

[0078] Further, the electronic device 230 can generate a second update region associated with the third reference region and the fourth reference region, for example, using a preset noise generation algorithm. The generation process of such a second update region can refer to the generation process of the transition region 415 and the first update region 450, for example.

[0079] Further, the electronic device 230 can determine a neighbor reference region adjacent to the set of reference regions, wherein the neighbor reference region is filled using a fourth texture different from the third texture. Accordingly, the electronic device 230 can fill the second update region using the fourth texture.

[0080] Illustratively, if the electronic device 230 determines that four horizontally continuous reference regions are all filled using the desert texture, the electronic device 230 can generate the second update region according to the position of the third and fourth reference regions among the four reference regions.

[0081] Further, the electronic device 230 can search forward from the last filled reference region filled using the desert texture according to the filling order. For example, the reference region before the four horizontally continuous reference regions can be filled using the snow texture, for example.

[0082] Accordingly, the electronic device 230 can fill the determined second update region using the snow texture, thereby avoiding filling using the same kind of continuous texture, and thus improving the realism of the picture.

[0083] The above discusses the processing process for the private texture in the transition region 415. In a series of embodiments, the electronic device 230 can also perform transition processing on the public texture in the transition region 415.

[0084] Specifically, the electronic device 230 can determine a set of public textures based on the first texture information of the first map region 405 and the second texture information of the second map region 410, wherein the set of public textures includes textures included in both the first map region 405 and the second map region 410. For example, the first map region 405 and the second map region 410 can both include the snow texture, for example.

[0085] Further, the electronic device 230 can perform transition processing on the part of the transition region 415 corresponding to the set of public textures. Illustratively, the electronic device 230 can apply a preset blur algorithm to the part of the transition region 415 corresponding to the set of public textures to perform transition processing. For example, the electronic device 230 can perform a Gaussian blur operation on the snow texture in the transition region 415, thereby improving the transition smoothness of the transition region 415.

[0086] In some embodiments, the first map region 405 and the second map region 410 may, for example, also have corresponding height information. The electronic device 230 may, for example, also fuse the first height information of the first map region 405 and the second height information of the second map region 410 in the transition region 415 based on an appropriate fusion manner. The fused height information may, for example, be further used to perform a filling process of the texture.

[0087] Such a fusion manner may, for example, be based on a manner of smooth transition, or may also consider the height characteristics in different regions to perform the fusion. The present disclosure is not intended to limit the specific manner of height fusion.

[0088] In some embodiments, as discussed with reference to Figure 2 the first map region and the second map region are, for example, adjacent ground regions in a virtual scene.

[0089] In some embodiments, the electronic device 230 may, for example, also generate a ground image corresponding to the first map region and the second map region based on the processed texture information.

[0090] Based on the above discussed processes, embodiments of the present disclosure are able to achieve smooth transition of textures between different regions by eliminating private textures in the region from the transition region, and performing re-filling of the texture, thereby improving the interactive experience of the user.

[0091] It should be understood that the specific region layout, texture type, etc. shown in the above description and the accompanying drawings are exemplary, and are not intended to constitute a limitation on the present disclosure.
