Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.
Fig. 1 is a first flowchart illustrating a model mapping method according to an embodiment of the present disclosure; the execution subject of the method can be a terminal device or a server. As shown in fig. 1, the method may include:
s101, creating model appliques of a basic model, and binding material identifiers for the model appliques; the base model comprises a hard surface model and/or a soft surface model;
the model applique is a model mapping technology, which means that a layer of independent model is covered on a model and an independent mapping is given to achieve the effect of mixing with the bottom model mapping. The model decal herein refers to a model to which a separate decal is assigned.
The basic model refers to an existing model, and in this embodiment, may refer to a model to which a texture needs to be added. The base model may be a pre-created model that is directly imported into the game engine when the method is executed.
The basic model may include a hard surface model or a soft surface model, and the hard surface model generally refers to an object model with a hard surface, such as a vehicle, weaponry, a building structure and the like, which is encountered in computer animation (cg) production and is commonly found in science fiction subject works. While soft surface models generally refer to models of objects with curved surfaces, such as game clothing and fabrics, encountered in computer animation.
Optionally, a material identifier may be bound to the created model applique, specifically, a material ball may be assigned to the model applique, the material ball may correspond to the material identifier, and texture and material information may be assigned to the material ball corresponding to the model applique through the material identifier.
S102, adding a model applique on the surface of a basic model; wherein, the material identification of the model applique is different from the material identification of the basic model.
The configuration operation here may be a UV expansion operation on the model decals to facilitate the addition of the model decals in a reasonable position on the base model surface.
Wherein UV refers to two-dimensional texture coordinates UV: vertex component information with a polygon and tessellated mesh for mapping the two-dimensional map onto the mesh of the three-dimensional model.
UV texture space: a two-dimensional texture coordinate system for defining UV, the UV texture space using letters U and V to indicate axes in the two-dimensional space.
It should be noted that the model applique and the base model have different material identifiers, so that the texture rendering operation on the base model does not cover the original texture of the base model, but attaches the newly added texture to the texture of the base model, thereby achieving higher precision of the new texture rendered on the base model.
S103, creating a texture material ball corresponding to the target model; the texture material ball is used for representing texture data of the target model at least.
The target model may refer to a model corresponding to a texture to be added to the base model, and taking the manufacturing of the machine top of the virtual character as an example, when the machine top is manufactured, a large amount of requirements for drawing normal map details are often met, such as manufacturing rivets or knobs on the machine top, then the base model may refer to the machine top, and the target model may refer to the rivets or knobs to be added.
The texture material ball contains texture data required for making the rivet, which may include: illumination information, normal information, etc.
When the target models are different, the corresponding texture material balls are different, and the target models can be rendered through texture data of the texture material balls.
In some embodiments, the target model may be a thread, a nut, a rivet, a pattern on a fabric, a window decoration on glass, etc., and may also be snow, frost, dust, etc., in a game scene.
And S104, adding the texture material ball of the target model to the corresponding position of the model applique so as to add the texture data of the target model to the surface of the basic model.
Based on the above description, the model applique can be understood as a pad attached to the airframe at the location of the rivet to be added, and by adding the model applique to the base model, the location of the target model to be added can be quickly located from the base model. Since the texture material ball contains the texture data of the target model, the texture data of the target model can be added to the surface of the base model, specifically to the position on the surface of the base model where the model applique is added, by adding the texture material ball of the target model to the corresponding position of the model applique. Since the model decal has a material identification independent of the base model, when the texture data of the target model is added to the surface of the base model by the model decal, the added texture data does not affect the texture of the base model.
Taking the basic model as a hard surface model such as a machine armor, taking the target model as a rivet, and taking the model applique added to the position a of the basic model as an example, through the way of the embodiment, the final rendering is as follows: a rivet is shown in position a on the surface of the vest.
In summary, in the model mapping method provided in this embodiment, the model applique independent of the base model is manufactured, and the model applique is added to the surface of the base model, so that when texture data of the target model is added to the surface of the base model, the position of the texture data to be added can be quickly located from the surface of the base model; the model applique is endowed with the material identification different from that of the basic model, so that when texture data of the target model is added to the basic model through the model applique, the added texture data cannot influence the original texture of the basic model, and in addition, compared with the traditional texture mapping mode for rendering the texture, the method has the advantages that the texture data is not required to be compressed and the like, so that the rendered texture has higher precision, and the method enables the rendered texture to be more convenient and fast in replacement operation without redrawing a new texture mapping.
FIG. 2 is a second flowchart illustrating a model mapping method according to an embodiment of the present disclosure; optionally, in step S101, binding a material identifier for the model applique may include:
and S201, creating a material interface corresponding to the model applique according to the material creating instruction.
The method may respond to an input material interface creating operation, and the material interface creating operation may be, for example, a right click operation when a cursor is located on a model decal, so that a property configuration interface corresponding to the model decal may be opened, and a material interface corresponding to the model decal is configured in the property configuration interface.
S202, binding corresponding material marks for the material interfaces.
The material interface is also the material ball, and the material interface created in the form of the material ball can facilitate the replacement and modification of the material interface.
In some embodiments, the material interface that can be created on one model applique is not limited to one, and may be multiple, where one material interface may be correspondingly bound with a material identifier, and the material identifiers bound by different material interfaces are different, and when texture data is transferred, the texture data can be transmitted into the corresponding material interface through the corresponding material identifier, so that the corresponding texture can be displayed at the corresponding position on the model applique.
Optionally, in step S102, adding a model applique to the surface of the base model may include: and performing texture mapping expansion on the model applique so as to add the texture mapping expanded model applique to the surface of the base model.
In some embodiments, the model decal may be texture mapped and expanded, i.e., UV expanded, in a modeling software such as Maya (three-dimensional modeling and animation software), where it is to be noted that UV refers to a type of built-in data in the model, which is essentially a coordinate system of a tangent space of the model, and the data may be used to attach the decal data to the surface of the model.
And the UV unfolding is the UV operation of the model, so that the chartlet can be conveniently displayed on the surface of the model according to a reasonable position. The UV expansion of the model applique can be understood as the model expansion of the model applique to obtain a coordinate mapping relationship between each point in the model before expansion and each point in the model after expansion.
For example: and (3) obtaining a three-dimensional model before the model applique is unfolded, obtaining a two-dimensional plane model after the model applique is unfolded, and then obtaining the coordinate mapping relation between each point in the three-dimensional model of the model applique and each point in the two-dimensional plane model after the model applique is unfolded.
In this embodiment, the model applique is a two-dimensional planar model before UV expansion, and thus after UV expansion, a two-dimensional planar model is obtained.
Alternatively, the model applique may be enabled to be added to the surface of the base model after the UV expansion operation has been performed on the model applique.
Optionally, in step S102, adding a model applique to the surface of the base model may include: and adding the model applique to the surface of the base model according to the target display style of the target model and the material type of the target model.
In the case of the target model determination, the target presentation style and the material type of the target model are determined. The target display style may refer to a display style of the target model on the base model, and the target display style of the target model may indicate a display position of the target model on the base model.
The material type of the target model may be determined from the material information of the target model, or the material type may be unique, and what model the target model is specifically based on the material type.
Each model corresponds to different material types, and the type of the model can be determined after the material types are obtained, for example, the target model can be determined to be threads, patterns on fabrics, snow, dust and the like in a game scene according to the material types.
Alternatively, based on the target presentation style of the target model and the material type of the target model, a position where the model applique is to be added to the base model may be determined, and the model applique is added to the surface of the base model according to the determined position.
FIG. 3 is a third flowchart illustrating a model mapping method according to an embodiment of the present disclosure; optionally, the adding the model applique to the surface of the base model according to the target display style of the target model and the material type of the target model in the above step may include:
s301, determining the spatial position relation between the model applique and the basic model according to the material type of the target model.
In this embodiment, in order to make the display effect of the target model rendered on the base model more realistic, when adding the model decal to the base model, the spatial position relationship between the model decal and the base model may also be determined.
For example: when the target model is snow, in order to make the rendered snow have a certain thickness, it can be realized by adding a model applique at a certain distance below the base model. When the target pattern is a pattern on a fabric, then, in order to make the pattern more three-dimensional, it can be achieved by adding a pattern decal at a distance above the base pattern.
It is also explained above that the type of the target model is determined by the material type of the target model, and then the spatial position relationship between the model applique and the base model can be further determined by determining the specific model (thread or snow or pattern, etc.) of the target model based on the material type of the target model.
S302, determining the target adding position of the model applique on the surface of the basic model according to the target display style and the spatial position relation of the target model.
And determining the position of the target model to be added to the base model according to the target display pattern of the target model, for example, if the target display pattern is that the target model is to be displayed in the upper right corner of the base model, then determining the position of the target model to be added to the base model as the upper right corner of the base model, and further combining the determined spatial position relationship, assuming that the spatial position relationship is 2 cm above the base model, determining that the model applique is to be added to the upper right corner of the base model and 2 cm above the surface of the base model, that is, the determined target addition position is represented by the upper right corner of the base model and 2 cm above the surface of the base model.
And S303, adding the model applique to a target adding position on the surface of the basic model.
Alternatively, based on the target addition position determined as described above, a model decal may be added to the target addition position.
FIG. 4 is a fourth flowchart illustrating a model mapping method according to an embodiment of the present disclosure; in step S103, creating a texture material ball corresponding to the target model may include:
s401, according to the input texture and material mapping, mapping information of the texture and material mapping is obtained, wherein the mapping information comprises one or more of the following items: material identification, texture data, and transparency data.
Alternatively, the texture and material map may be obtained directly from a database, and may be specific model detail map materials, for example: the input is screw detail map material, pattern detail map material, etc.
The input texture material map contains information representing the texture details of the model, which may be called map information, and the map information of different models is different.
The texture interface is used for indicating texture and transparency data of the texture map, and the texture interface is used for transmitting texture and transparency data of the texture map.
For different target models, the mapping information of texture mapping contains texture data, but the texture data of different target models are different. For the models with transparency requirements for patterns and the like on the fabric, the map information of the models can also contain transparency data.
The data type contained in the mapping information of each specific target model can be adaptively adjusted, so that the target model can be obtained through more real rendering.
S402, according to the mapping information of the texture material mapping, a texture material ball corresponding to the target model is established.
Optionally, based on the map information obtained from the texture material map, a texture material ball corresponding to the target model may be created, where the created texture material ball includes the rendering data related to the target model.
FIG. 5 is a fifth flowchart illustrating a model mapping method according to an embodiment of the present disclosure; in step S104, adding the texture material ball of the target model to the corresponding position of the model applique may include:
and S501, responding to the selection operation of the target texture material ball, and determining a target material interface of the target texture material ball on the model applique according to the material identifier in the target texture material ball.
Generally, since the texture material ball corresponding to the target model may include a plurality of texture material balls, in a specific rendering, only the target texture material ball needs to be determined from the plurality of texture material balls, and the target texture material ball is determined from the plurality of texture material balls in response to a selection operation of the target texture material ball, a click operation of the target texture material ball, or the like.
Optionally, based on the selected target texture material ball, a material identifier included in the target texture material ball may be obtained, and the material identifier may be used to determine a material interface to be added to the model applique by the target texture material ball.
S502, inputting texture data and/or transparency data in the target texture marker material ball into the target material interface.
Based on the determined target material interface, texture data and/or transparency data in the target texture target material ball may be transferred to the target material interface. The method can be characterized in that the dragging operation of the target texture material ball is responded, the target texture material ball is dragged to the position of a target material interface of the model applique, and therefore texture data and/or transparency data in the target texture material ball are input to the target material interface.
When the target texture material ball only contains texture data, the texture data is transferred to the target material interface, and when the target texture material ball contains texture data and transparency data, both the texture data and the transparency data are transferred to the target material interface.
Fig. 6 is a sixth schematic flowchart of a model mapping method according to an embodiment of the present application; in step S104, adding the texture material ball of the target model to the corresponding position of the model applique may include:
s601, obtaining offset mapping information corresponding to the model applique, wherein the offset mapping information comprises: the offset of each vertex in the model decal.
In some embodiments, for some target models, in addition to texture mapping information, offset mapping information may be included during rendering, for example, when the target model is snow, the thickness of the rendered snow may be generated by the offset mapping information, and at the same time, a gradual change effect of the thickness of the snow may be generated.
The offsets herein may refer to offsets of vertices in the model, and the offset map information is used to record the amount of offset in world space (the positive Z-axis direction of world space) of each vertex in the created individual model decal.
The offset map information may be generated according to the effect of the drawn snow, the amount of offset of each vertex is determined according to the effect of the snow actually intended to be rendered, and the target offset amount of each vertex can be obtained based on the offset amount of each vertex in the model decal acquired in the offset map information multiplied by a preset coefficient.
And S602, responding to the selection operation of the target texture material ball, and determining a target material interface of the target texture material ball on the model applique according to the material identifier in the target texture material ball.
In the same manner as step S501, in such a scenario that further includes offset mapping information, the target texture interface may also be determined according to the material identifier included in the selected target texture target material ball.
And S603, inputting texture data and/or transparency data in the target texture target material ball and the offset of each vertex in the model applique in the offset applique information into the target material interface.
In this scenario, different from step S502, the texture data and/or transparency data in the target texture marker material ball and the information of the offset amount of each vertex in the model decal in the offset map information may be both transferred to the target material interface.
Of course, the above description only lists the map information that may be involved in rendering the target model, and in practical applications, there may be other map information, and specifically, when the target model is determined according to the target model, each map information corresponding to the target model is also determined, and based on the determined map information, the map information is transferred to the target material interface corresponding to the target model, so as to render the target model on the base model.
Optionally, the method may further comprise: and responding to the selection operation of the new target texture material ball, and updating the currently added texture material ball at the corresponding position of the model applique according to the new target texture material ball.
According to the method, texture data of different models are created in a manner of creating texture material balls, model decals are added on a basic model, and material identifiers are bound for the model decals, so that the texture to be added on the basic model can be quickly replaced in a manner of replacing the texture material balls transferred to material interfaces corresponding to the material identifiers.
Optionally, the new target texture material ball may be selected in response to a click operation on the new target texture material ball, and the new target texture material ball is dragged to the texture material ball to be replaced, so as to update the texture material ball added at the corresponding position on the model overlay, thereby updating the texture of the target model rendered on the base model.
Optionally, in step S102, adding a model applique to the surface of the base model may include: and scaling the model applique according to the actual size proportion of the target model and the base model, and adding the scaled model applique on the surface of the base model.
In some embodiments, the model appliques may be appropriately scaled first when they are applied to the base model surface, the scaling being dependent on the actual dimensions of the target model, e.g., rivets, screws.
Optionally, a model decal is added to the surface of the base model based on the scaled model decal.
Additionally, the creation of the model applique in the present method may include: in response to the creation operation of the model decal, a planar model is created as the model decal.
Alternatively, it may include: responding to the surface copying operation of the target area on the basic model, and acquiring a target surface where the target area is located; a model decal is generated from the target surface.
In the embodiment, two ways of creating model decals are provided, and for some hard surface base models, when adding model decals thereto, a new plane model can be directly created as a model decal.
For some soft surface basic models, because the surface of the soft surface basic model has a certain curvature, the model applique is generated in a surface copying mode, so that the model applique can be better attached to the surface of the basic model, the problem that the gap exists between the model applique and the basic model cannot be caused, and the texture of the finally rendered target model can be more real.
The method will be explained below by specific examples.
Firstly, the method comprises the following steps: take the basic model as the character machine A and the target model as the rivet on the machine A as an example.
The method comprises the following steps: a flat model can be created as a model decal in the modeling software (maya is used here), and the model decal is subjected to UV unfolding operation (UV is divided) in the maya software, and a separate material interface is given to bind a material identifier.
Step two: and (4) manufacturing rivets on the model, and shrinking the model applique manufactured in the step one to a proper size and putting the model applique at a proper position on the basic model body.

Step four: and (4) importing the final model manufactured in the step two into a game engine UE4, dragging the rivet material ball in the step three into the material interface specified by the model applique in the step one, and then seeing the final detail effect, namely displaying the rivet at the target position on the armor.

Step three: the model in step two was subjected to a UV unfolding operation in maya software.
Step four: the game engine UE4 introduces a texture mapping material, and creates a plurality of texture material balls for model decal use. In addition, transparency is a problem due to the soft-surface fabric, and the pattern texture map may also include transparency data.
Step five: and (4) importing the final model manufactured in the step two into a game engine UE4, dragging the texture material ball in the step three into a material interface appointed by the model applique copied in the step two, and seeing the final detail effect, namely displaying the patterns on the target position of the fabric garment.
Thirdly, the method comprises the following steps: take the example that the basic model is rock and the target model is snow on the rock.

Step three: the model in step two was subjected to a UV unfolding operation in maya software.
Step four: a snow texture ball for use by the model applique is made in game engine UE4 for use by the model applique created in step two. In addition, in order to render the thickness of the snow so that the snow is more realistic, offset map information is also introduced into the game engine UE 4.
