Description

Technical Field

[0001] This disclosure relates to the field of computers, and more specifically, to a method, apparatus, storage medium, and electronic device for adjusting a virtual model. Background Technology

[0002] Currently, when rendering virtual models, in order to better match the square texture map and avoid jagged edges, it is necessary to deform and adjust the mapping of the virtual model in texture space (e.g., straighten it).

[0003] In related technologies, during the deformation and adjustment of a virtual model, the texture points to be adjusted are usually manually selected from the virtual model and moved or rotated to arrange them into a straight line. Then, the texture points to be deformed and adjusted are selected row by row, and the scaling or alignment tools are used to uniformly deform and adjust the texture points along a certain axis.

[0004] The aforementioned method of deforming and adjusting virtual models manually is inefficient, ineffective, and unsuitable for complex models. Furthermore, this method can cause distortion in certain areas of the model, resulting in poor performance in virtual model deformation and adjustment.

[0005] There is currently no effective solution to the above problems. Summary of the Invention

[0006] This disclosure provides at least some embodiments of a method, apparatus, storage medium, and electronic device for adjusting a virtual model, in order to at least solve the technical problem in the related art where some parts of the virtual model are distorted when the virtual model is deformed.

[0007] According to one embodiment of this disclosure, a method for adjusting a virtual model is provided, comprising: obtaining at least one block to be adjusted constituting the model to be adjusted, wherein the block to be adjusted is any one of a plurality of texture blocks obtained by expanding the model to be adjusted in texture space; determining the master order edge located on the block to be adjusted, and identifying the texture identifier of the current master order point on the master order edge to obtain a first texture identifier, wherein the master order edge is any one of a plurality of continuous edges in the block to be adjusted, and the current master order point is a texture point on the master order edge; determining a deformation adjustment mode of texture points contained in a second texture set based on the first texture identifier, wherein the second texture point set consists of texture points in the block to be adjusted other than the master order point on the master order edge; and deforming and adjusting the texture points contained in the second texture set based on the deformation adjustment mode to obtain an adjusted virtual model.

[0008] According to one embodiment of this disclosure, an adjustment device for a virtual model is also provided, comprising: an acquisition module, configured to acquire at least one adjustable block constituting the model to be adjusted, wherein the adjustable block is any one of a plurality of texture blocks obtained by unfolding the model to be adjusted in texture space; an identification module, configured to determine the master order edge located on the adjustable block and identify the texture identifier of the current master order point on the master order edge to obtain a first texture identifier, wherein the master order edge is any one of a plurality of continuous edges in the adjustable block, and the current master order point is a texture point on the master order edge; a determination module, configured to determine the deformation adjustment mode of the texture points contained in a second texture set based on the first texture identifier, wherein the second texture point set consists of texture points in the adjustable block other than the master order point on the master order edge; and an adjustment module, configured to deform and adjust the texture points contained in the second texture set based on the deformation adjustment mode to obtain an adjusted virtual model.

[0009] According to one embodiment of this disclosure, a non-volatile storage medium is also provided, wherein a computer program is stored in the non-volatile storage medium, and the computer program is configured to execute the above-described adjustment method for the virtual model when running.

[0010] According to one embodiment of this disclosure, an electronic device is also provided, including a memory and a processor, wherein the memory stores a computer program and the processor is configured to run the computer program to perform the above-described method for adjusting the virtual model.

[0011] In at least some embodiments of this disclosure, a method is adopted whereby the main order edges of the block to be adjusted are deformed and adjusted simultaneously with the texture points outside the main order edges. After obtaining at least one block to be adjusted constituting the model to be adjusted, the main order edges located on the block to be adjusted are determined, and the texture identifiers of the current main order points on the main order edges are identified to obtain a first texture identifier. Then, based on the first texture identifier, the deformation adjustment mode of the texture points contained in the second texture set is determined. Finally, the texture points contained in the second texture set are deformed and adjusted based on the deformation adjustment mode to obtain the adjusted virtual model. The second texture point set consists of texture points in the block to be adjusted, excluding the main order points on the main order edges.

[0012] As shown above, the deformation and adjustment of the virtual model eliminates the need for manual operation, thus avoiding the inefficiency of manual deformation and adjustment and improving the overall efficiency. Furthermore, during the deformation and adjustment of the main edges of the model, all texture points except those on the main edges are adjusted simultaneously. This avoids the problem of partial model distortion caused by adjusting only the main edges in related technologies, reducing the occurrence of inconsistencies in virtual model deformation and improving the overall effect of virtual model deformation and adjustment.

[0013] Therefore, the solution provided in this disclosure achieves the purpose of deforming and adjusting the virtual model, thereby improving the effect of deforming and adjusting the virtual model and solving the technical problem of distortion of some models when deforming virtual models in related technologies.

[0030] According to one embodiment of this disclosure, an embodiment of a method for adjusting a virtual model is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0031] This method embodiment can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, the mobile terminal can be a smartphone (such as an Android phone, iOS phone, etc.), tablet computer, PDA, mobile Internet Device (MID), PAD, game console, and other terminal devices. Figure 1 This is a hardware structure block diagram of a mobile terminal for a virtual model adjustment method according to an embodiment of this disclosure. For example... Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a central processing unit (CPU), graphics processing unit (GPU), digital signal processing (DSP) chip, microprocessor (MCU), programmable logic device (FPGA), neural network processor (NPU), tensor processor (TPU), artificial intelligence (AI) type processor, etc.) and a memory 104 for storing data are also shown. Optionally, the mobile terminal may further include a transmission device 106 for communication functions, an input / output device 108, and a display device 110. Those skilled in the art will understand that... Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0032] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the virtual model adjustment method in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the aforementioned virtual model adjustment method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network.

[0036] In one embodiment of this disclosure, the virtual model adjustment method can run on a local terminal device or a server. When the virtual model adjustment method runs on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and client devices.

[0037] In one possible implementation, this disclosure provides a method for adjusting a virtual model. The terminal device executing the method can be either the aforementioned local terminal device or a client device in the aforementioned cloud interaction system. Figure 2 This is a flowchart of a virtual model adjustment method according to one embodiment of the present disclosure, such as... Figure 2As shown, the method includes the following steps:

[0038] Step S202: Obtain at least one adjustment block constituting the model to be adjusted, wherein the adjustment block is any one of the multiple texture blocks obtained by expanding the model to be adjusted in the texture space.

[0039] In step S202, the model to be adjusted is a virtual model, such as a virtual character, tree, cloud, or rock in a game. The block to be adjusted is the mapping of the virtual model in texture space, that is, the block to be adjusted is the texture block obtained after the virtual model is unfolded in texture space. The block to be adjusted can be the texture block obtained after the entire model to be adjusted is unfolded in texture space, or it can be the texture block obtained after a part of the model to be adjusted is unfolded in texture space. For example, for a virtual character model, the block to be adjusted can be the texture block obtained after the finger part is unfolded in texture space.

[0040] Furthermore, the shape of the blocks to be adjusted can be linear, C-shaped, S-shaped, O-shaped, P-shaped, etc. In this disclosure, [the shape of the blocks is to be adjusted]. Figure 3 The following example illustrates how to adjust the deformation of a texture block to a straight line.

[0041] In one alternative embodiment, after obtaining the model to be adjusted, the terminal device maps the model to be adjusted into a texture space to obtain multiple texture blocks. Then, in response to the user's selection operation, it determines at least one texture block to be adjusted from the multiple texture blocks.

[0042] In another alternative embodiment, the terminal device can divide the model to be adjusted into multiple model blocks and, in response to a user's selection, select a target model block from the multiple model blocks. Then, the target model block is mapped into texture space to obtain the block to be adjusted.

[0043] Step S204: Determine the master order edge located on the block to be adjusted, and identify the texture identifier of the current master order point on the master order edge to obtain the first texture identifier.

[0044] In step S204, the master-order edge is any one of the multiple continuous edges in the block to be adjusted, and the current master-order point is a texture point on the master-order edge. A continuous edge is a combination of edges in the block to be adjusted that are connected end-to-end without breaks or branches. The master-order edge is also a type of continuous edge, used as a reference for the deformation adjustment of the block to be adjusted. The master-order point is a point on the master-order edge, that is, each continuous edge consists of multiple texture points, and the texture point located on the master-order edge is the master-order point. Each master-order point or texture point has an identifier, namely a texture identifier.

[0045] In one alternative embodiment, the terminal device may, in response to a user's selection operation, determine the main order edge from a plurality of consecutive edges contained in the block to be adjusted, such as... Figure 3 As shown, the user selected a continuous middle edge as the main sequence edge. After determining the main sequence edge, the terminal device uses one endpoint of the main sequence edge as the starting point and sequentially numbers the texture points on the main sequence edge to obtain the aforementioned first texture identifier. That is, in this embodiment, the first texture identifier represents the position information of the main sequence point on the main sequence edge.

[0046] Step S206: Determine the deformation adjustment mode of the texture points contained in the second texture set based on the first texture identifier.

[0047] In step S206, the second texture point set consists of texture points in the block to be adjusted, excluding the master order points on the master order edges.

[0048] It should be noted that each master sequence point corresponds to a second texture set. For the current master sequence point, the terminal device can determine the row number range of the texture points contained in the second texture set in the preset control table through the first texture identifier of the current master sequence point, and determine the deformation adjustment mode corresponding to the second texture set according to different row number ranges. The preset control table stores relevant information about the master sequence point (e.g., master sequence point identifier) ​​and relevant information about the texture points associated with the master sequence point (e.g., texture point identifier).

[0049] Furthermore, it should be noted that deforming and adjusting the texture points in the second texture set mainly involves rotating the texture points within the second texture set. Using different deformation adjustment modes to deform and adjust the texture points in the second texture set can reduce the occurrence of inconsistent distortions in the adjusted blocks.

[0050] Step S208: Based on the deformation adjustment mode, the texture points contained in the second texture set are deformed and adjusted to obtain the adjusted virtual model.

[0051] It should be noted that, since the texture points in the second texture set in step S206 are not texture points on the main order edges, in this disclosure, during the deformation adjustment of the main order edges in the model to be adjusted, the texture points in the model to be adjusted, excluding the main order points on the main order edges, are adjusted simultaneously. This avoids the problem in related technologies where only the main order edges are adjusted, leading to partial model distortion and deformation. It reduces the occurrence of inconsistencies in virtual model deformation adjustment and improves the effect of virtual model deformation adjustment. For example, for... Figure 3 After the blocks to be adjusted are deformed and adjusted as shown, the desired result can be obtained. Figure 4 The linear texture blocks shown are composed of... Figure 4As shown in the schematic diagram of the texture blocks, there is no problem of model distortion or deformation in the adjusted texture blocks.

[0052] Based on the scheme defined in steps S202 to S208 above, it can be understood that, in at least some embodiments of this disclosure, a method is adopted whereby the main sequence edges of the block to be adjusted are deformed and adjusted simultaneously with the texture points outside the main sequence edges. After obtaining at least one block to be adjusted constituting the model to be adjusted, the main sequence edges located on the block to be adjusted are determined, and the texture identifier of the current main sequence point on the main sequence edge is identified to obtain a first texture identifier. Then, based on the first texture identifier, the deformation adjustment mode of the texture points contained in the second texture set is determined. Finally, the texture points contained in the second texture set are deformed and adjusted based on the deformation adjustment mode to obtain the adjusted virtual model. The second texture point set consists of texture points in the block to be adjusted other than the main sequence points on the main sequence edges.

[0053] It is noteworthy that the deformation and adjustment of the virtual model requires no manual operation, thus avoiding the inefficiency of manual deformation and adjustment, and thereby improving the efficiency of virtual model deformation and adjustment. Furthermore, during the deformation and adjustment of the main edges of the model to be adjusted, all texture points in the model except those on the main edges are adjusted simultaneously. This avoids the problem in related technologies where adjusting only the main edges leads to partial model distortion, reducing the occurrence of inconsistencies in virtual model deformation and adjustment, and improving the overall effect of virtual model deformation and adjustment.

[0054] Therefore, the solution provided in this disclosure achieves the purpose of deforming and adjusting the virtual model, thereby improving the effect of deforming and adjusting the virtual model and solving the technical problem of distortion of some models when deforming virtual models in related technologies.

[0055] In one optional embodiment, after obtaining the block to be adjusted, the terminal device can store the relevant information of the master sequence points on the master sequence edges in a preset control table. Specifically, the terminal device first determines the starting position of the master sequence edges, then sorts the first texture point set based on the starting position to obtain a sorting result. Finally, according to the sorting result, the texture identifiers of the master sequence points contained in the first texture point set are stored in the target column of the preset control table. The first texture point set consists of all the master sequence points on the master sequence edges.

[0056] Optionally, after determining the master-order edges, the terminal device acquires all texture points on the master-order edges to obtain the master-order points, denoted as the master-order point set (i.e., the first texture point set) M. uvAnd starting from one end of the main sequence edge, sort the main sequence points on the main sequence edge, and store the relevant information of the main sequence points in the first column of the main sequence point control table (i.e., the preset control table) in order. For example, in Figure 3 In the process, the endpoints of the main sequence edge are A1 and B. The terminal device sorts the main sequence points on the main sequence edge starting from A1 and stores the relevant information of the main sequence points in the first column of the preset control table. The order of the main sequence points corresponds to their row number in the preset control table.

[0057] It should be noted that, in addition to storing information about the master sequence point, the preset control table also stores information about texture points on other continuous edges related to the master sequence point.

[0058] Specifically, the terminal device traverses the second texture point set, determines the current texture point, and identifies the adjacent edges corresponding to the current texture point from the blocks to be adjusted. Then, it obtains the neighboring points corresponding to the adjacent edges to get the third texture point set, and detects the number of texture points in the third texture point set that belong to the first texture point set. Finally, it updates the preset control table based on the number of texture points.

[0059] It should be noted that the aforementioned adjacent edges include at least the line segment containing the current texture point, and the adjacent point is the endpoint of the adjacent edge. Optionally, the terminal device can detect the number of line segments passing through the current texture point, and determine the number of adjacent edges based on this line segment data, with the endpoints corresponding to the adjacent edges being the adjacent points. For example, in Figure 5 In the adjacent edge diagram shown, the current texture point is C. There are four line segments passing through the current texture point C: C1C, CC2, C3C, and CC4. The endpoints corresponding to the adjacent edges, besides the current texture point C, also include endpoints C1, C2, C3, and C4. Therefore, the third texture point set corresponding to the current texture point C consists of C1, C2, C3, and C4. After determining the adjacent points, the terminal device detects the number of endpoints (i.e., the number of texture points) among the above four endpoints that are primary sequence points, and then updates the preset control table based on the number of texture points.

[0060] In one optional embodiment, the terminal device determines whether a neighboring point is a master point by detecting whether its position coincides with the master point position in the first texture point set. If none of the neighboring points corresponding to the current texture point are master points, then the number of texture points is zero. If the number of texture points is zero, then all neighboring points are recorded as the current texture point, for example, using... Figure 5For example, if there is no master order point among the neighboring points C1, C2, C3, and C4, then the neighboring points C1, C2, C3, and C4 are recorded as the current texture point. Then, the above steps are repeated, that is, the second texture point set is traversed to determine the current texture point, and the neighboring edge corresponding to the current texture point and the neighboring point corresponding to the neighboring edge are determined from the block to be adjusted. Then, the number of texture points belonging to the first texture point set among the neighboring points is detected until the obtained neighboring points contain one or more master order points.

[0061] Furthermore, after determining the number of texture points, the terminal device can update the preset control table based on the number of texture points. Specifically, when the number of texture points is a preset threshold, the target master sequence point corresponding to the current texture point is determined, and the texture identifier of the current texture point is added to the first target row of the preset control table, where the first target row is the row where the target master sequence point is located in the preset control table. Optionally, the aforementioned preset threshold is 1, that is, when the number of texture points is 1, it indicates that among the neighbors of the current texture point, it belongs to M. uv If there is only one texture point, the terminal device will find the row of the master sequence point corresponding to the current texture point in the preset control table and record the texture identifier of the current texture point into a new column corresponding to that row in the preset control table.

[0062] When the number of texture points exceeds a preset threshold, determine the multiple master sequence points corresponding to the current texture point, calculate the average row number of the multiple master sequence points in the preset control table, determine the second target row based on the average, and then add the texture identifier of the current texture point to the second target row. That is, when it belongs to M... uv When there are more than one texture point, the average value of the row numbers of the multiple master sequence points corresponding to the current texture point in the preset control table is obtained, and the row of the texture identifier of the current texture point in the preset control table is determined based on the average value.

[0063] Optionally, when the average value is an integer, the row number that is the average value is determined to be the second target row. For example, if the row numbers of the main sequence points corresponding to the current texture point are 12 and 14, then the average value is 13. The terminal device stores the texture identifier corresponding to the current texture point in a new column of row 13 of the preset control table.

[0064] Optionally, when the average value is not an integer, the two integers adjacent to the average value are obtained, and the rows corresponding to the two integers are determined to be the second target row. For example, if the main sequence point corresponding to the current texture point is row number 13, 14, and 20 in the preset control table, the terminal device will simultaneously record the relevant information corresponding to the current texture point into rows 15 and 16 of the preset control table.

[0065] In one alternative embodiment, before determining the texture coordinates of the current master sequence point located on the master sequence edge and obtaining the first texture coordinates, the terminal device also performs an overall rotation on the block to be adjusted.

[0066] Specifically, the terminal device determines the first master sequence point and the next master sequence point from the master sequence edges according to the sorting result. Then, it determines the sub-master sequence edge between the first master sequence point and the next master sequence point, and determines the angle between the sub-master sequence edge and the first direction to obtain the first angle. Finally, based on the first angle, it performs a rotation operation on the block to be adjusted with the first master sequence point as the axis to obtain the rotated block to be adjusted.

[0067] It should be noted that the first master sequence point mentioned above is the first texture point of the master sequence edge, that is, the first texture point in the preset control table according to the order of master sequence points. The next master sequence point is the second texture point in the preset control table. The first direction mentioned above can be the positive direction of the X-axis in the world coordinate system.

[0068] Optional, with Figure 3 Taking the schematic diagram of the block to be adjusted as an example, the first master sequence point is A1, the next master sequence point is A2, and the sub-master sequence edge between the first master sequence point and the next master sequence point is A1A2. The angle α between this sub-master sequence edge A1A2 and the positive direction of the X-axis in the world coordinate system (i.e., the first angle) is determined. Using the first master sequence point as the axis, the entire block to be adjusted is rotated 180°-α, thus obtaining... Figure 6 The rotated blocks to be adjusted are shown.

[0069] It should be noted that the first included angle mentioned above can be defined as the angle through which one side rotates counterclockwise around the axis point to another side. The included angle can be the angle between the sub-main ordered edge and the positive direction of the X-axis in the world coordinate system, or it can be the angle between the sub-main ordered edge and any axis in the world coordinate system. In practical applications, it can be selected according to actual needs, and no specific limitation is made here.

[0070] Furthermore, after rotating the blocks to be adjusted as a whole, the terminal device executes step S206, which is to determine the deformation adjustment mode of the texture points contained in the second texture set based on the first texture identifier.

[0071] Specifically, the terminal device first obtains the range influence factor, then determines the current target row number of the current master sequence point in the preset control table based on the first texture identifier, and determines multiple row number ranges based on the range influence factor and the current target row number. Finally, it determines the deformation adjustment mode of the texture points contained in the second texture set based on the row number range of the texture points contained in the second texture set. Texture points in different row number ranges in the preset control table correspond to different deformation adjustment modes.

[0072] It should be noted that the aforementioned range influence factor can be determined based on practical experience. For example, the range influence factor can be 5. Setting the aforementioned range influence factor can reduce the number of texture points that need to be calculated in each iteration, thereby improving the system's computational performance. It can also avoid the problem that when calculating texture points at one end of the C-shaped virtual model, the texture points at the other end are affected, thus improving the deformation adjustment effect of the virtual model.

[0073] Optionally, after obtaining the range influence factor, the terminal device calculates the difference between the current target row number and the range influence factor to obtain the first row number, and calculates the sum of the current target row number and the range influence factor to obtain the second row number. Then, based on the first row number and the second row number, the range of the first row number, the range of the second row number, and the range of the third row number are determined. The maximum row number in the range of the first row number is less than the first row number, the minimum row number in the range of the second row number is the first row number, the maximum row number in the range of the second row number is the second row number, and the minimum row number in the range of the third row number is greater than the second row number.

[0074] For example, if the range influence factor is R and the current target row number is i, then the first row number is iR, the second row number is i+R, the range of the first row number is less than iR; the range of the second row number is greater than or equal to iR, and less than or equal to i+R; the range of the third row number is greater than i+R.

[0075] Optionally, adjusting the current texture point is prohibited if the row number corresponding to the current texture point is within the range of the first row number. That is, if the row number of the current texture point in the preset control table is less than iR, the current texture point does not need to be deformed and adjusted.

[0076] It should be noted that when the row number corresponding to the current texture point is within the range of the third row number, directly rotating the texture point according to the first angle γ can not only save the system's calculation time, but also avoid the problem of distortion in the texture block after deformation adjustment caused by calculating one end of the C-shaped block and using the relevant information of the texture point at the other end.

[0077] Optionally, when the row number corresponding to the current texture point is within the range of the second row number, a texture weight value is generated based on the first reference coordinate system and the second reference coordinate system, and the target rotation angle of the current texture point is determined based on the texture weight value. Here, the positive direction of the first axis in the first reference coordinate system is different from the positive direction of the first axis in the second reference coordinate system.

[0078] It should be noted that this scenario can be further divided into six sub-scenes, each with a different method for calculating texture weight values. After obtaining the texture weight values, the product of the texture weight values ​​and the preset angle is calculated to obtain the target rotation angle corresponding to the current texture point.

[0079] Optionally, when the row number corresponding to the current texture point is within the range of the third row number, the current texture point is rotated by a first angle with the origin of the first reference coordinate system as the axis.

[0080] In this scenario, the terminal device obtains all texture points recorded in rows with row numbers greater than i+R and all main sequence points with row numbers greater than i from the preset control table, and rotates by an angle γ (i.e. the first angle mentioned above) with the origin of the first reference coordinate system as the axis. When γ>0, it rotates counterclockwise; when γ<0, it rotates clockwise.

[0081] The terminal device can calculate the aforementioned first angle in the first reference coordinate system.

[0082] Specifically, after obtaining the third texture coordinates of the previous master sequence point and the fourth texture coordinates of the next master sequence point, the terminal device determines a first vector based on the third and first texture coordinates, and determines a second vector based on the fourth and first texture coordinates. Then, it calculates the angle between the first and second vectors to obtain the first angle. Here, the current master sequence point has a row number greater than 1 in the preset control table, the first vector points to the third texture coordinate, and the second vector points to the fourth texture coordinate.

[0083] In addition, the terminal device can create a first reference coordinate system and a second reference coordinate system with the first texture coordinate as the origin. In the first reference coordinate system, the positive direction of the first axis is the direction pointed to by the first vector, and in the second reference coordinate system, the positive direction of the first axis is the direction pointed to by the second vector.

[0084] Optionally, the terminal device starts from the second master sequence point in the preset control table and records the current master sequence point as M. uvi A first reference coordinate system and a second reference coordinate system are created using this as the origin, wherein the positive X-axis of the first reference coordinate system points to the previous principal sequence point M. uv(i-1) ,like Figure 7 As shown; the positive X-axis of the second reference coordinate system points to the next principal sequence point M. uv(i+1) ,like Figure 8 As shown. Figure 9 As shown, obtain and The angle between them can be used to obtain α. Let γ = 180 - α to obtain the first angle γ.

[0085] In one optional embodiment, when the row number corresponding to the current texture point is within the range of the second row number, the terminal device determines the target angle interval corresponding to the current texture point among multiple preset angle intervals; then, based on the target angle interval, it determines the target calculation mode corresponding to the texture weight value, and determines the weight value corresponding to the target calculation mode to obtain the texture weight value. The multiple preset angle intervals are determined based on the second angle between the line connecting the current texture point and the origin of the first reference coordinate system and the first direction of the first reference coordinate system.

[0086] In the above process, the second angle is the angle between the line connecting the texture point and the origin of the first reference coordinate system and the positive X-axis of the first reference coordinate system. Multiple preset angle intervals can be determined based on the first angle γ. Among them, four segmentation angles can be calculated based on the first angle, and the coordinate system with the current texture point as the origin can be divided into 6 intervals (i.e., the preset angle intervals mentioned above) based on these four segmentation angles. For different preset angle intervals, the corresponding texture weight values ​​are calculated in different ways.

[0087] Before determining the target angle interval corresponding to the current texture point among multiple preset angle intervals, the terminal device generates a first parameter value and a second parameter value based on a first angle. Then, it generates multiple preset angles based on the first parameter value, the second parameter value, and the first angle, and generates multiple preset angle intervals based on the multiple preset angles. The sum of the first parameter value and the second parameter value is a fixed value.

[0088] Optionally, the terminal device obtains all texture points with row numbers greater than iR and less than i+R from the preset control table, records the angle between the line connecting each texture point to the origin and the positive X-axis of the first reference coordinate system as β, and then divides the current texture point into 6 sets (i.e. the preset angle interval mentioned above) based on the relationship between the angle of β and the 4 segmentation angles.

[0089] Let the first parameter value Second parameter value When γ > 0, ξ = 1, τ = 0; when γ < 0, ξ = 0, τ = 1, meaning that regardless of whether γ is greater than 0 or less than 0, the sum of the first parameter value and the second parameter value is 1. The aforementioned preset angles (i.e., segmentation angles) can be denoted as θ1, θ2, θ3, and θ4, where θ1, θ2, θ3, and θ4 respectively satisfy the following equation:

[0090] θ1=(270-180*ξ-γ*ξ)

[0091] θ2=(270-180*ξ-γ*τ)

[0092] θ3=(270-180*τ-γ(ξ)

[0093] θ4=(270-180*ξ-γ*τ)

[0094] The first preset angle interval is [(θ2*τ), (θ1*ξ+360τ)], and the texture points within this angle interval are denoted as set 1; the second preset angle interval is (θ1, θ2), and the texture points within this angle interval are denoted as set 2; the third preset angle interval is [(ξ*θ2+τ*α), (ξ*α+τ*θ1)], and the texture points within this angle interval are denoted as set 3; the fourth preset angle interval is ((ξ*α+τ*θ4), (ξ*θ3+τ*α)], and the texture points within this angle interval are denoted as set 4; the fifth preset angle interval is (θ3, θ4), and the texture points within this angle interval are denoted as set 5; the sixth preset angle interval is [θ4, (θ2*τ)], and the texture points within this angle interval are denoted as set 6.

[0095] It should be noted that by setting the first parameter value ξ and the second parameter value τ, the problem of sets 1, 2, and 3 being located on different sides of the X-axis of the first reference frame due to γ ​​being greater than 0 or less than 0 can be avoided, thus ensuring that the texture points of sets 1, 2, and 3 are aligned with M. uv(i+1) Located on the same side of the X-axis in the first reference coordinate system. For example... Figure 10 A schematic diagram of the first reference coordinate system shown, where γ > 0, and as shown below. Figure 11 The diagram shows the first reference coordinate system where γ < 0, and the texture points of sets 1, 2, and 3 are related to M. uv(i+1) Located on the same side of the X-axis in the first reference coordinate system. Wherein, Figure 10 and 11 Intervals 1 to 6 in the above-mentioned first preset angle interval to sixth preset angle interval respectively.

[0096] It should be noted that, given the texture weight value, the terminal device can obtain the target rotation angle by calculating the product of the texture weight value and the first angle. That is, the target rotation angle δ satisfies the following formula:

[0097] δ=γ*s

[0098] In the above formula, γ is the first angle; s is the texture weight value.

[0099] The calculation method for the texture weight value varies depending on the preset angle range in which the current texture point is located. Before explaining the calculation method for the texture weight value corresponding to different preset angle ranges, the following limitations need to be made:

[0100] Main sequence point M uv(i+1) The X-coordinate value in the second reference coordinate system is denoted as X. (i+1) ; Main sequence point M uv(i-1)The X-coordinate value in the first reference coordinate system is denoted as X. (i-1) ; Main sequence point M uvi Weighting of the X-coordinates of a point in the first and second reference coordinate systems

[0101] Additionally, the X-coordinate of the current texture point P in the second reference coordinate system is denoted as D. (i+1) The X-coordinate of the current texture point P in the first reference coordinate system is denoted as D. (i-1) Then the first weight value Second weight value Where r1 represents the influence weight of the subsequent sub-major order edge on the current texture point P, and r2 represents the influence weight of the previous sub-major order edge on the current texture point P. p This represents the proportional coefficients of the weights of r1 and r2 on the current texture point P.

[0102] Scenario 1: If the current texture point P belongs to set 1, then δ is represented by the following formula:

[0103] δ=s*γ=r2*ψ*γ

[0104] In the above formula, the texture weight value s = r² * ψ. In this formula, the closer the X-coordinate of the current texture point P is to M... uv(i-1) The closer the weighting is to 0, the better; if the X-coordinate of the current texture point P is closer to M... uvi The closer the weighting is to ψ, the better.

[0105] Scenario 2: If the current texture point P belongs to the second set, then δ is represented by the following formula:

[0106] δ=s*γ={[(1-ψ)*r1+ψ]*r p +[r2*ψ*(1-r p )]}*γ,

[0107] In the above formula, the texture weight value s = [(1-ψ)*r1+ψ]*r p +[r2*ψ*(1-r p )]. Where, when γ > 0, δ ∈ [0, γ]; when γ < 0, δ ∈ [γ, 0].

[0108] It should be noted that since the X-coordinates of the texture points in the second set are located on the positive X-axis of both the first and second reference coordinate systems, the texture weight values ​​can be calculated by combining the weight calculation methods of Scene 1 and Scene 3, and expressed as r. pThe weight ratios obtained from the two algorithms are adjusted. Specifically, the closer β is to the first preset angle range, the greater the weight calculated using the weight calculation method of Scene 1; the closer β is to the third preset angle range, the greater the weight calculated using the weight calculation method of Scene 3. Finally, the terminal device combines the weights from both methods to obtain the added weight for the current texture point P. If the calculated value of δ exceeds the master order point rotation angle, δ is limited to within the master order point rotation angle range.

[0109] Scenario 3: If the current texture point P belongs to the 3rd set, then δ is represented by the following formula:

[0110] δ=s*γ=[(1-ψ)*r1+ψ]*γ

[0111] In the above formula, the texture weight value s = (1-ψ)*r1+ψ. In this formula, the closer the X-coordinate of the current texture point P in the second reference coordinate system is to M... uv(i+1) The closer the weighting is to 1, the better; if the X-coordinate of the current texture point P is closer to M... uvi The closer the weighting is to ψ, the better.

[0112] Scenario 4: If the current texture point P belongs to set 4, then δ is represented by the following formula:

[0113]

[0114] In the above formula, the texture weight value

[0115] It should be noted that since the X-coordinates of the texture points in the fifth preset angle interval are all negative in both reference coordinate systems, if the linear algorithm of the first and third preset angle intervals is continued, the texture points in the fifth preset angle interval will intersect with the texture points in the fourth and sixth preset angle intervals after rotation. Therefore, in this embodiment, the weight of the fifth preset angle interval is calculated based on the overall angle change. The total angle of the four, fifth, and sixth preset angle intervals (180+|γ|) is compressed to 180 degrees. Therefore, the weights at the boundaries of the fifth preset angle interval and two adjacent angle intervals are calculated according to the proportions of the three angle intervals, and these weights are used as the weights at the boundaries of the fourth and sixth preset angle intervals. Thus, the weight of the boundary between the fourth and fifth preset angle intervals is... The weights of the boundaries between the fifth and sixth preset angle intervals are: After calculating the boundary weights, the linear relationship between the X-coordinates of the second parameter coordinate system and the weights continues within the fourth preset angle interval, starting from the boundary. Linear transition to D (i+1) =X(i+1) One is sufficient.

[0116] Scenario 5: If the current texture point P belongs to set 5, then δ is represented by the following formula:

[0117]

[0118] In the above formula, the texture weight value In this formula, the weight of the change is calculated directly based on the angle proportion. The closer the weight is to the boundary between the fourth and fifth preset angle intervals, the closer its weight is to the boundary between the fourth and fifth preset angle intervals. The closer it is to the boundary of the fifth preset angle interval and the sixth preset angle interval, the closer its weight is to...

[0119] Scenario 6: If the current texture point P belongs to set 6, then δ is represented by the following formula:

[0120]

[0121] In the above formula, the texture weight value Similar to the fourth preset angle interval, the sixth preset angle interval continues to use the linear relationship between the coordinate X value and the weight in the first parameter coordinate system, starting from the boundary D. (i-1) =0 Linear transition to D (i-1) =X (i-1) 0 is sufficient.

[0122] The design principles of the algorithms for each preset angle range can reduce the deformation that exists after straightening the texture blocks, and make the texture points on both sides of the main sequence edge maintain their relative stability with the main sequence edge after the main sequence edge is straightened.

[0123] In addition, in order to keep the X-coordinate values ​​relatively close to the preceding and following master sequence points M uv(i-u) and M uv(i+1) However, regarding the positional relationship between texture points that are relatively far from the main edge and the main edge, in this embodiment, the β angle is not directly used as the basis for weight calculation within the first preset angle interval, the third preset angle interval, the fourth preset angle interval, and the sixth preset angle interval. Instead, the coordinate X values ​​of the first reference coordinate system and the second reference coordinate system are used.

[0124] It should be noted that by iterating through the master order points in the first texture set and repeatedly executing the texture point deformation and adjustment method described above, until the operation on the second-to-last master order point is completed, the result will be as follows. Figure 4 The virtual model shown is after deformation and adjustment.

[0125] Furthermore, the solution provided in this embodiment is applicable to all texture blocks. Regardless of how the selected main sequence edge is distorted, the texture points on both sides of each edge can be rotated appropriately and synchronously while the main sequence edge is gradually rotated and straightened. The solution using the partitioning algorithm ensures that the texture points will not become excessively dense or sparse in local areas after rotation, or significantly change their distance from the main sequence edge, thereby ensuring the deformation adjustment effect of the texture module.
