[0092] In addition, the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0093] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0094] In the related art, multiple bones are manually added to the character model, and the weight value of each bone is manually adjusted. The weight value of the bone affects the deformation strength of the character model mesh, and then the shape of the character model is adjusted. However, in the related art, it is necessary to manually add bones and weight values ​​to adjust the shape of the character model, which is relatively complicated and has low adjustment efficiency.

[0095] In response to the above-mentioned technical problems existing in the related technology, an embodiment of the present application provides a method for adjusting the morphology of a character model, in which the preset dynamic bones and the preset static bones of the target virtual character model are associated with the basic skeleton, the preset dynamic bones rotate with the virtual camera, and the angle between the preset dynamic bones and the preset static bones is calculated. The vertex position of the target virtual character model is automatically adjusted according to the angle, thereby realizing automatic adjustment of the morphology of the target virtual character model without manual adjustment, and the adjustment process is convenient and efficient.

[0096] Figure 1 A flow chart of a method for adjusting the morphology of a role model provided by an embodiment of the present invention is shown as follows: Figure 1 As shown, the method may include:

[0097] S101 . In response to a viewing angle adjustment operation input to a target virtual character model, a preset dynamic skeleton of the target virtual character model is controlled to rotate along with a virtual camera.

[0098] The preset dynamic skeleton is a pre-set follower skeleton associated with the basic skeleton in the target virtual character model. The preset dynamic skeleton is a skeleton pre-added to the basic skeleton, and the preset dynamic skeleton can also be called an M (move) skeleton.

[0099] In some embodiments, the variable of the driving editor can be selected as rotational difference, a locked track can be added in advance for the preset dynamic skeleton, and the tracking target can select a virtual camera; in response to the perspective adjustment operation input to the target virtual character model, the virtual camera starts to rotate, and the preset dynamic skeleton of the target virtual character model can rotate with the virtual camera.

[0100] It should be noted that the viewing angle adjustment operation may be an operation inputted by an external device or a touch operation, wherein the external device may be a mouse and / or a keyboard. For example, the viewing angle adjustment operation may be a drag operation.

[0101] S102: Calculate the angle between the preset dynamic skeleton and the preset static skeleton in the target virtual character model.

[0102] The preset static skeleton is a fixed skeleton that is pre-set and associated with the basic skeleton. The preset static skeleton is a skeleton that is pre-added to the basic skeleton, and the preset static skeleton can also be called an S (stop) skeleton.

[0103] In some embodiments, the preset dynamic skeleton can rotate along the preset coordinate axis of the virtual camera, while the preset static skeleton remains stationary. Then, an angle can be formed between the preset dynamic skeleton and the preset static skeleton, and the angle value corresponding to the angle is calculated.

[0104] For example, the preset coordinate axis of the virtual camera may be the Z axis of the virtual camera.

[0105] S103 . Adjust the vertex positions of the target virtual character model according to the included angle to adjust the shape of the target virtual character model.

[0106] The target virtual character model may include a plurality of vertices, and each vertex has a corresponding initial position.

[0107] In the embodiment of the present application, as the virtual camera rotates, the presentation perspective of the target virtual character model also changes accordingly. The vertex position of at least one target vertex among multiple vertices of the target virtual character model can be automatically adjusted according to the angle, so that the presentation effect of the target virtual character model at any perspective is better and more reasonable, without the need for manual subsequent corrections to the target virtual character, and the adjustment process is also more convenient and efficient.

[0108] In summary, an embodiment of the present invention provides a method for adjusting the morphology of a character model, including: responding to a viewing angle adjustment operation input to a target virtual character model, controlling a preset dynamic skeleton of the target virtual character model to rotate with a virtual camera; wherein the preset dynamic skeleton is a preset follower skeleton associated with a basic skeleton in the target virtual character model; calculating the angle between the preset dynamic skeleton and the preset static skeleton in the target virtual character model; wherein the preset static skeleton is a preset fixed skeleton associated with the basic skeleton; according to the angle, adjusting the vertex position of the target virtual character model to adjust the morphology of the target virtual character model. The preset dynamic skeleton rotates with the virtual camera, calculating the angle between the preset dynamic skeleton and the preset static skeleton, and automatically adjusting the vertex position of the target virtual character model according to the angle, thereby realizing automatic adjustment of the morphology of the target virtual character model without manual adjustment, and the adjustment process is convenient and efficient.

[0109] In some embodiments, the methods described in S101 to S103 above can be implemented based on shapekeys (shape key fusion). Before S101 above, a virtual camera can be added, and the virtual camera perspective can be set to a preset perspective. For example, the preset perspective can be a side view angle; enter the shapekeys panel and add controls to add vertex data of the target virtual character model by operating the add controls. The perspective effect diagram of the target virtual character model can also be adjusted under the virtual camera perspective and displayed.

[0110] Optional, Figure 2 A flow chart of a method for adjusting the morphology of a role model provided by an embodiment of the present invention is shown as follows: Figure 2 As shown, the process of adjusting the vertex position of the target virtual character model according to the included angle in the above S103 to adjust the shape of the target virtual character model may include:

[0111] S201: Determine whether the included angle is within a preset angle range corresponding to a first area in a target virtual character model.

[0112] The first area may be a partial area in the target virtual character model.

[0113] For example, the target virtual character model can be a human face model, the first area can be the left half of the face or the right half of the face, the first area can also be the upper half of the face or the lower half of the face. The target virtual character model can be a complete human model, and the first area can also be an arm or a foot.

[0114] In addition, the variable of the driving editor may be selected as a scripted expression, and then set within a preset angle range corresponding to the first area.

[0115] S202: If the included angle is within a preset angle range, only the vertex position of the first region is adjusted according to the included angle.

[0116] In the embodiment of the present application, if the included angle is within a preset angle range, only the vertex position of the first region is adjusted according to the included angle, and other regions except the first region in the target virtual character model are adjusted.

[0117] For example, the target virtual character model may be a human face model, and the first area may be the upper half of the face. If the angle is within a preset angle range, only the vertex position of the upper half of the face may be adjusted, and the adjustment of the lower half of the face is disabled.

[0118] Among them, if the angle is within the preset angle range corresponding to the first area, the virtual camera is rotated to the first area at this time, that is, the first area can be completely presented in the interface.

[0119] Optionally, the method further includes:

[0120] If the area to be adjusted is switched from the first area to the second area, the preset angle range corresponding to the first area is processed to obtain the preset angle range corresponding to the second area, so as to adjust the second area based on the preset angle range corresponding to the second area.

[0121] Herein, a processing rule may be used to process the preset angle range corresponding to the first area to obtain the preset angle range corresponding to the second area.

[0122] Optionally, the first area and the second area are two symmetrical areas centered on the preset rotation axis, and the process of processing the preset angle range corresponding to the first area to obtain the preset angle range corresponding to the second area may include:

[0123] The preset angle range corresponding to the first area is mirrored to obtain the preset angle range corresponding to the second area.

[0124] In some embodiments, the preset angle range corresponding to the first area is mirrored to obtain the preset angle range corresponding to the second area. If the second area is within the preset angle range, only the vertex position of the first area is adjusted according to the included angle.

[0125] For example, the preset angle range corresponding to the first area may be an angle greater than a preset angle threshold, and the preset angle range corresponding to the second area may be an angle less than the preset angle threshold.

[0126] In an embodiment of the present application, if the first area and the second area are two symmetrical areas centered on a preset rotation axis, the adjustment results of the vertex positions of the first area can be saved and the adjustment results of the vertex positions of the first area can be mirrored, that is, the corresponding vertex positions of the second area are adjusted according to the adjustment results of the vertex positions of the first area, so that the adjustment of the second area is more efficient.

[0127] For example, the first area and the second area are two symmetrical areas centered on the Y axis. If the target virtual character model is a human face model, the first area can be the left half of the face or the right half of the face; of course, the target virtual character model can also be a complete human model, then the first area can be the left half or the right half.

[0128] Optional, Figure 3 A flow chart of a method for adjusting the morphology of a role model provided by an embodiment of the present invention is shown as follows: Figure 3 As shown, the process of adjusting the vertex position of the target virtual character model according to the angle in the above S103 may include:

[0129] S301, determining an adjustment value of a vertex position according to an included angle.

[0130] S302: Adjust the vertex position according to the adjustment value.

[0131] The adjustment value of the vertex position may be referred to as value intensity.

[0132] It should be noted that the adjustment value of the vertex position of the first area can be mirrored to obtain the adjustment value of the vertex position of the second area. Each angle has a corresponding adjustment value of the vertex position. For example, the adjustment value of the vertex position can be 0.631.

[0133] Optional, Figure 4 A flow chart of a method for adjusting the morphology of a role model provided by an embodiment of the present invention is shown as follows: Figure 4 As shown, the method may include:

[0134] S401, displaying multiple preset character expressions.

[0135] Therein, a plurality of preset character expressions are obtained respectively, and then the plurality of preset character expressions are displayed.

[0136] In some embodiments, when obtaining each preset character expression, a texture is drawn, basic vertex data is added to the mesh, deformation data is added, and the mesh shape is adjusted to obtain the preset character expression. Thumbnails are rendered using an orthographic perspective according to the preset character expression, and thumbnails of multiple preset character expressions are displayed.

[0137] S402: In response to a selection operation on a plurality of preset character expressions, a plurality of target character expressions are determined.

[0138] The plurality of target character expressions refers to at least one target character expression.

[0139] It should be noted that the selection operation for multiple preset character expressions can be an operation input by mouse and / or keyboard, or a touch operation, or an operation input by other methods, and the embodiment of the present application does not impose specific restrictions on this.

[0140] For example, the selection operation for multiple preset character expressions may be a click operation or a long press operation.

[0141] S403: adjusting the expression of the target virtual character model according to the expression of the target character.

[0142] Wherein, the expression of the target virtual character model is adjusted according to at least one target character expression to obtain the adjusted expression of the target virtual character model.

[0147] In the embodiment of the present application, if the number of target character expressions is one, then in response to the adjustment operation for the one target character expression, the one target character expression is adjusted to obtain an adjusted target character expression. If the number of target character expressions is multiple, then in response to the adjustment operation for multiple target character expressions, the multiple target character expressions are adjusted respectively to obtain multiple adjusted target character expressions.

[0158] Each target character expression has a corresponding control, and the control can be displayed near the expression corresponding to the target character expression.

[0159] Figure 8 A schematic diagram of an interface display provided by an embodiment of the present invention is shown as follows: Figure 8 As shown, the interface can display multiple target character expressions and controls corresponding to each target character expression.

[0160] In response to the adjustment operation on each target character's expression in S501, the process of adjusting each target character's expression to obtain each adjusted target character's expression may include:

[0161] S702 , in response to adjustment operations on controls corresponding to expressions of respective target characters, respectively adjust expressions of respective target characters to obtain adjusted expressions of respective target characters.

[0162] It should be noted that, in response to the adjustment operation of the control corresponding to each target character's expression, the expression of each target character can be adjusted to different degrees according to different adjustment operations. For example, if the adjustment operation is a drag operation on the control, the expression of the target character can be adjusted to different degrees according to the drag distance.

[0163] Optionally, the control is a slideable control, and the adjustment operation is a drag operation on the control. Figure 8 As shown, the slidable control may include: a sliding shaft and a slider, and in response to a drag operation on the slider, the slider may move on the sliding shaft.

[0164] In some implementations, the position control recognized by the driver can be set to the local X axis of the slider. Specifically, when implemented based on shapekey, the object can select the slider corresponding to the expression of the target character, and the remaining parameters of the driver are inconvenient. The type is set to X location, and the space is set to local space.

[0165] In addition, you can also add limit locations to the slider to set the maximum and minimum values, and set local space to limit the slider position so that the entire slider does not exceed the range of the sliding axis.

[0166] It should be noted that, when implemented based on shapekey, the driver type can be modified to a scripted expression. The scripted expression can represent that when the adjustment parameter is greater than or equal to the preset parameter, the corresponding operation is performed. For example, the operations performed may include: at least one of S902, S1002, and S1103, so that the adjustment of the character's expression is richer and more flexible.

[0167] The scripted expression may be anniuX(slider name and axis)>0.7or(slider name and axis)>0.7. When the X-axis value of a slider is greater than 0.7 or the X-axis value of another slider is also greater than 0.7, a corresponding operation is performed.

[0168] Of course, the expression can also be used in Python (a computer programming language) to express if else with a slight modification, 0if slider X == (value) else (value), which has the same effect.

[0169] Optional, Fig. 9 A flow chart of a method for adjusting the morphology of a role model provided by an embodiment of the present invention is shown as follows: Fig. 9 As shown, in the above S702, in response to the adjustment operation of the control corresponding to each target character expression, the process of adjusting each target character expression respectively to obtain each adjusted target character expression may include:

[0170] S901. In response to an adjustment operation of a control on a target character's expression, an adjustment parameter is determined.

[0171] Different adjustment operations correspond to different adjustment parameters.

[0172] In some embodiments, the controls of the target character's expression may include: a slider and a sliding axis. In response to an input drag operation on the slider, the slider can move on the sliding axis; when the drag operation is dragging from left to right, the slider can move from left to right on the sliding axis, and the adjustment parameter can become larger; when the drag operation is dragging from right to left, the slider can move from right to left on the sliding axis, and the adjustment parameter can become smaller.

[0173] Optionally, the range of the adjustment parameter can be between 0 and 1, or between 0 and 0.8, and the upper limit value can be set according to actual needs, and the embodiment of the present application does not impose specific restrictions on this.

[0174] S902: If the adjustment parameter is greater than or equal to the preset parameter, convert the target map in the target character expression into the preset map to obtain an adjusted target character expression.

[0175] The target map in the target character's expression may be an eye map or a mouth map.

[0176] In some embodiments, the eye sticker may include stickers Figure 1 Hetie Figure 2 ,stick Figure 1 Hetie Figure 2 The eye shape of the target character is different. When the adjustment parameter is less than the preset parameter, the eye map of the target character's expression is displayed as Figure 1 When the adjustment parameter is greater than or equal to the preset parameter, the eye map of the target character's expression is displayed as Figure 2 For example, you can paste Figure 2 When the adjustment parameter is greater than 0.7, Figure 2 Take effect.

[0177] Optional, Fig.10 A flow chart of a method for adjusting the morphology of a role model provided by an embodiment of the present invention is shown as follows: Fig.10 As shown, in the above S702, in response to the adjustment operation of the control corresponding to each target character expression, the process of adjusting each target character expression respectively to obtain each adjusted target character expression may include:

[0178] S1001. In response to an adjustment operation of a control on a target character's expression, an adjustment parameter is determined.

[0179] The process of S1001 is similar to the process of S901 described above, and will not be described in detail here.

[0180] S1002: If the adjustment parameter is greater than or equal to the preset parameter, the mesh face in the target character's expression is converted into the preset mesh face to obtain an adjusted target character's expression.

[0181] It should be noted that the target character expression may include multiple mesh patches. If the adjustment parameter is greater than or equal to the preset parameter, at least one of the multiple mesh patches of the target character expression may be converted into a corresponding preset mesh patch.

[0182] Among them, different mesh patches may correspond to different preset mesh patches.

[0183] For example, a mesh patch A has a corresponding preset mesh patch B. If the adjustment parameter is less than 0.6, the target character's expression contains mesh patch A. If the adjustment parameter is greater than or equal to 0.6, the mesh patch A in the target character's expression is deleted, and the preset mesh patch B is added at the location of the original mesh patch A.

[0184] Optional, Fig.11 A flow chart of a method for adjusting the morphology of a role model provided by an embodiment of the present invention is shown as follows: Fig.11 As shown, in the above S702, in response to the adjustment operation of the control corresponding to each target character expression, the process of adjusting each target character expression respectively to obtain each adjusted target character expression may include:

[0185] S1101. In response to an adjustment operation of a control on a target character's expression, an adjustment parameter is determined.

[0186] The process of S1101 is similar to the process of S901 described above, and will not be described in detail here.

[0187] S1102: Adjust a first weight of a preset first map and a second weight of a preset second map of the target character's expression according to the adjustment parameter.

[0188] Among them, as the adjustment parameters change, the first weight can change according to the preset rules, for example, from small to large or from large to small, and the second weight can change according to the preset rules, for example, from small to large or from large to small, and the sum of the first weight and the second weight can be 1.

[0189] S1103: According to the first weight and the second weight, the preset first texture and the preset second texture are merged to obtain an adjusted target character expression.

[0190] Among them, the preset first map and the preset second map can both be maps for target parts of the target character's expression, for example, they can be maps for the nose, chin, eyebrows, glasses, etc.

[0191] In an embodiment of the present application, the first weight and the second weight are used to merge the preset first map and the preset second map of the target part to obtain the target map of the target part, and the original map of the target part of the target character's expression is set as the target map to adjust the expression of the target character.

[0192] In addition, the slider of each texture has a corresponding driver, which can be copied and pasted on the corresponding slider of other textures, so as to realize parameter configuration of other textures and improve the efficiency of parameter configuration.

[0193] It should be noted that if Figure 8 As shown, the adjusted target character expression can be displayed on the target virtual character model.

[0194] In summary, compared with the method of directly switching sequence frames to adjust the expression in the related art, the use of at least one of S902, S1002, and S1103 to adjust the expression of the target character effectively avoids the problem of abrupt expression transitions, and can make the expression transition of the target character more natural and reasonable.

[0195] Fig.12 A schematic diagram of an interface display provided by an embodiment of the present invention is shown as follows: Fig.12 As shown, the interface may also include additional components, each additional component having a corresponding additional component control, and in response to a selection operation on the additional component control, the additional features of the additional control are adjusted, and the adjusted additional features are added to the expression of the target virtual character model.

[0196] For example, the additional control may be a tear control, the corresponding additional feature may be tears, and when adjusting the tears, the size of the teardrops may be adjusted; the additional control may be a blush control, the corresponding additional feature may be blush, and when adjusting the blush, the color depth of the blush may be adjusted.

[0197] In summary, an embodiment of the present invention provides a method for adjusting the morphology of a character model, including: responding to a viewing angle adjustment operation input to a target virtual character model, controlling a preset dynamic skeleton of the target virtual character model to rotate with a virtual camera; wherein the preset dynamic skeleton is a preset follower skeleton associated with a basic skeleton in the target virtual character model; calculating the angle between the preset dynamic skeleton and the preset static skeleton in the target virtual character model; wherein the preset static skeleton is a preset fixed skeleton associated with the basic skeleton; according to the angle, adjusting the vertex position of the target virtual character model to adjust the morphology of the target virtual character model. The preset dynamic skeleton rotates with the virtual camera, calculating the angle between the preset dynamic skeleton and the preset static skeleton, and automatically adjusting the vertex position of the target virtual character model according to the angle, thereby realizing automatic adjustment of the morphology of the target virtual character model without manual adjustment, and the adjustment process is convenient and efficient.

[0198] Moreover, multiple expressions can be used in combination, making the expression adjustment of the target virtual character model more flexible and rich, with more expression styles. It can also support direct adjustment on the target virtual character model, which is intuitive to operate, does not require skinning, and has a natural transition. It also has high scalability. If you want to add or adjust existing expressions later, you can directly adjust and add them on the grid or click on the grid that needs to be adjusted to change it.
