Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The background to which this application relates is described in further detail below:
with the continuous development of the related field of games, the production requirements of games are higher and higher, and at least one virtual character is usually included in the games, wherein the virtual character may need to make some corresponding facial expressions in the games.
At present, in the prior art, when generating a facial expression of a virtual character, a model of a virtual object is generally established, bones of the model are established in a manual operation mode, a controller, an attribute association, an expression and the like are manually created for each bone, and the created bones, the controller, a constraint command and the expression are relied on, so that the expression of the virtual character can be generated.
Therefore, in the prior art, when generating an expression for a virtual character, the expression of each virtual character needs to be generated manually, but the manual processing method causes the processing efficiency of the facial expression of the virtual character to be low, and the expression is relatively single.
In a possible implementation manner, when manual processing is performed manually, in order to increase the processing speed, a smaller number of bones may be created, so as to reduce the workload and increase the processing speed, however, when the number of bones is smaller, the expression that can be generated is comparatively single, for example, as can be understood by referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram of creating a model bone in the prior art provided by an embodiment of the present application, and fig. 2 is a schematic diagram of an expression obtained by creating a bone in the prior art provided by an embodiment of the present application.
As shown in fig. 1, it is assumed that two bones 101 and 102 are generally manually created for controlling an eyelid of a left eye and an eyelid of a right eye respectively currently for a certain model, and only the eyes of the virtual character can be opened or closed, wherein the schematic diagram of the opened eyes is shown in fig. 1, and the schematic diagram of the closed eyes is shown in fig. 2, so that only the virtual character with the two bones shown in fig. 1 is created, and only blinking animation can be performed, thereby resulting in a single expression effect of the virtual character and failing to realize the expression of the vivid image of the virtual character.
In summary, in the prior art, if the manual processing method is used, if the vividness of the expression of the virtual character needs to be improved, a large number of bones, controllers, and the like need to be created, so that the processing efficiency of the facial expression of the virtual character is low.
Based on the problems in the prior art, the application provides the following technical concept: a large number of repetitive commands, complicated attribute association and other operations in the skeleton generating process are written into the script language, and the written script language is directly adopted to process each model, so that each model does not need to be manually processed, and the expression processing efficiency of the virtual character is effectively improved.
The method for processing the model expression provided by the present application is described below with reference to a specific embodiment, fig. 3 is a flowchart of the method for processing the model expression provided by the embodiment of the present application, fig. 4 is a schematic view of an operation interface of a target plug-in provided by the embodiment of the present application, fig. 5 is a schematic view of generating a pair of sites provided by the embodiment of the present application, and fig. 6 is a schematic view of generating bones and binding information provided by the embodiment of the present application.
As shown in fig. 3, the method includes:
s301, obtaining a face model to be processed.
The face model is a model of the face of the virtual character which needs expression processing, and modeling can be performed on the face of the virtual character to obtain the face model to be processed.
S302, responding to the starting operation of the target plug-in, starting the target plug-in, and displaying an operation interface of the target plug-in on the graphical user interface.
In this embodiment, the target plug-in is a plug-in for generating the contra-position point, skeleton, controller, attribute association, expression of the model.
In a possible implementation manner, for example, a series of operations of generating a model, such as position, bone, controller, attribute association, and expression, may be written into a scripting language by using a maxscript language of 3DSMAX, and the target plug-in the embodiment is obtained by making according to the written scripting language.
Therefore, in this embodiment, the target plug-in may include logic codes for generating a pair point, a skeleton, a controller, an attribute association, and an expression of the model, and the target plug-in may automatically execute the corresponding logic codes in the background only when a trigger-related operation is detected, so as to implement generation of the corresponding data.
The starting operation for the target plug-in may be, for example, a click operation on the graphical user interface, or may also be an operation of triggering a command line for starting the target plug-in to run.
In one possible implementation, the operation interface of the target plug-in may be as shown in fig. 4, referring to fig. 4, the operation interface of the target plug-in may include a first control 401 and a second control 402, wherein the first control 401 may be used to trigger the corresponding logic code to generate at least one alignment point of the face model, and the second control may be used to trigger the corresponding logic code to generate the skeleton of the face model and the binding information between the skeleton and the face model.
In other possible implementation manners, the positions, shapes, sizes and the like of the first control and the second control can be selected according to actual requirements; or the target plug-in may also include only one control, and generate two sub-controls by operating one control, or the target plug-in may also include controls other than the first control and the second control.
And S303, responding to the trigger operation of the first control on the operation interface, and generating at least one alignment point of the face model.
In a possible implementation manner, the first control is a clickable control, and the triggering operation for the first control may be, for example, a click operation; or the trigger operation for the first control may also be a long-press operation, and the like, and the implementation manner of the trigger operation is not limited in this embodiment as long as the trigger operation can trigger the function corresponding to the first control.
In one possible implementation, logic code that generates the contra-location point of the model may be triggered in response to a click operation on the first control, and after the logic code is automatically executed, at least one contra-location point of the face model may be generated.
One possible implementation of the face model is shown in fig. 5, and as shown in fig. 5, a first control 502 is included in the target plug-in 501, wherein the first control 502 is used for generating at least one alignment point of the face model.
For example, after the logic code generating the contra-location points of the model is executed, at least one contra-location point of the face model, such as 503 in fig. 5, and each circular point on the face model in fig. 5 is a contra-location point, and in this embodiment, the contra-location point may be used to indicate the position of the generated skeleton in the face model.
In the actual implementation process, the setting position of each pair of sites, the setting number of the pair of sites, and the like can be set correspondingly according to the actual requirements, and the setting mode of the pair of sites is not particularly limited in this embodiment.
And S304, responding to the triggering operation of a second control on the operation interface, and generating the skeleton of the face model and the binding information between the skeleton and the face model according to the position of the at least one contraposition point.
In a possible implementation manner, the binding information between the skeleton and the face model may include controllers corresponding to the skeleton, attribute association between the skeleton and the controllers, and an expression, where each skeleton corresponds to a controller, and in a possible implementation manner, a plurality of skeletons having an association relationship may correspond to one controller.
In this embodiment, the bone corresponds to a first performance parameter, where the first performance parameter is used to indicate the performance of the bone, and the controller corresponds to a second performance parameter, where the second performance parameter is used to indicate the first performance parameter, so the controller in this embodiment may control the first performance parameter of the bone according to the second performance parameter, for example, the controller may be a component in 3dsMax that is used to process an animation task, so that the controller may control the performance parameters of each control item, such as the position, rotation, and scaling of the bone, to control the bone to implement a corresponding action, and may also be used to store parameter values of an animation keyframe.
And the attribute association in this embodiment is used to associate the first performance Parameter with the second performance Parameter, for example, the attribute association may be a Wire Parameter attribute association tool of 3ds Max, and through the attribute association tool, the performance parameters of any one controller and any one bone may be associated, so that an effect that adjusting the performance parameters of one controller may automatically change the performance parameters of the corresponding bone is achieved.
And the expression in this embodiment is used to associate the first performance parameter with the second performance parameter, where the expression may be mathematically connected to the related attributes of different objects, for example, the related parameter of one controller may be set in a mathematical formula manner, and as long as the related parameter of the controller is changed, the parameters of other associated bones will automatically change, so that the corresponding bones will also change in performance.
In this embodiment, the second control is a clickable control, and the triggering operation for the second control may be, for example, a clicking operation, or may also be the remaining operations for triggering the function corresponding to the second control.
In one possible implementation, the logic code for generating the skeleton, controller, attribute association, and expression of the model may be triggered in response to a triggering operation for the second control, for example, see 601 in fig. 6, and the second control 602 is included in the target plug-in 601, where the second control 602 is used for generating the skeleton, controller, attribute association, and expression of the face model.
After the logic code is automatically executed, the skeleton, controller, attribute association, and expression of the face model may be generated, and the finally generated content is shown as the content on the face model 603 in fig. 6.
In the present embodiment, the alignment points may indicate positions of the bones on the face model, and in one possible implementation, the bones of the face model in a preset number range may be generated according to the position of the at least one alignment point and a preset picture precision, as shown in fig. 6, and the positions of the bones on the generated face model and the positions of the at least one alignment point in fig. 5 are consistent.
And if the preset picture precision is higher, a larger number of bones of the face model can be set, and if the preset picture precision is lower, a smaller number of bones of the face model can be set, and the preset picture precision can be selected according to actual requirements.
Then, the controller, attribute association and expression of the skeleton of the face model can be generated according to the logical codes of the controller, attribute association and expression of the generation model in the target plug-in.
In the actual implementation process, the setting position of each bone, the setting number of bones, the controller of each bone, the attribute association, the specific implementation of the expression, and the like, may be set correspondingly to the logic code according to the actual requirements, and the setting manner of this embodiment is not particularly limited.
The controller, the attribute association, and the expression of the skeleton are used for processing related logic operations in the process of generating the expression of the virtual object, taking a mouth in a facial expression as an example, for example, the controller, the attribute association, and the expression may be set for the skeleton of the mouth, when the virtual object is required to make a smiling expression, the skeleton of the mouth corner is controlled to move upward, and when the virtual object is required to make a smiling expression, the skeleton of the mouth is controlled to move to a specified position, so that the expression of the virtual object may be controlled, and implementation manners of generating the controller, the attribute association, the expression, and the like of each skeleton in the target plug-in may be written with corresponding logic codes according to actual requirements, which is not particularly limited in this embodiment.
And S305, controlling the expression of the face model according to the skeleton and the binding information of the face model.
After the skeleton of the face model and the binding information are generated, the generated skeleton can be added to the corresponding position of the face model, and the movement of the skeleton is controlled according to the binding information between the skeleton and the face model, so that the expression of the face model is controlled.
The method for processing the model expression provided by the embodiment of the application comprises the following steps: and acquiring a face model to be processed. And in response to the starting operation for the target plug-in, starting the target plug-in, and displaying an operation interface for the target plug-in on the graphical user interface.
