As shown in fig. 1, the system architecture of the embodiment of the present application may include, but is not limited to: a terminal device 11 and a server 12. The terminal device 11 includes, for example: user equipment such as cell-phones, panel computer, personal computer.

In the related art, the schemes for changing the effect of the clothes are as follows:

(1) the model and the corresponding map are replaced together, and the model is divided into a partial model and an integral model, the integral replacement is to replace the whole body with another model except the head so as to achieve the purpose of changing, and the partial replacement is used for replacing partial models such as a breastplate, trousers, gloves and the like; (2) the map replacement means that the model is kept unchanged and different map textures are replaced; (3) local color changing: in some fixed parts of the character, the color of the mask part is changed by mask calculation.

The existing model replacement is not only integral model replacement or local model replacement, but also the whole manufacturing process is more complex and the manufacturing cost is higher because new models, skeleton binding and mapping are involved; the similar reason of map replacement and model replacement is that the model is kept unchanged, but a new map is also needed for replacement, and the flow and the cost are increased; the local color changing is to change the color by a shade mode, which is simple to realize and low in cost, but if only the color is changed, the effect is limited, and the effect of ink halation cannot be shown.

According to the method, the target shading chartlet corresponding to the initial chartlet in the current orientation of the virtual camera is obtained, the target shading chartlet is the chartlet obtained after shading processing is carried out on the basic pattern in the initial chartlet in the current orientation, the virtual object is rendered according to the observation visual angle of a user, namely the current orientation of the virtual camera, the target shading chartlet and the initial chartlet, so that the shading effect of the virtual object is shown downwards in the current orientation, and the showing effect of the virtual object is improved.

In one embodiment, the pattern of the virtual character map exhibits different shading effects as the viewing angle of the user varies, i.e., the orientation of the virtual camera varies.

In the cloud game operation mode, the game program operation main body and the game picture presentation main body are separated, the storage and the operation of the image processing method are completed on the cloud game server, and the client device is used for receiving and sending data and presenting the game picture, for example, the client device can be a display device with a data transmission function close to a user side, such as a mobile terminal, a television, a computer, a palm computer and the like; however, the terminal device performing the information processing is a cloud game server in the cloud. When a game is played, a player operates the client device to send an operation instruction to the cloud game server, the cloud game server runs the game according to the operation instruction, data such as game pictures and the like are encoded and compressed, the data are returned to the client device through a network, and finally the data are decoded through the client device and the game pictures are output.

In an alternative embodiment, the terminal device may be a local terminal device. Taking a game as an example, the local terminal device stores a game program and is used for presenting a game screen.

The method is suitable for 3D games in the traditional Chinese painting style and the ink and wash style, and is also suitable for 2D picture processing of fixed lenses.

The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a schematic flowchart of an embodiment of an image processing method provided in the present application. As shown in fig. 2, in this embodiment, a terminal device provides a graphical user interface, where the graphical user interface includes a scene image captured by a virtual camera, and the scene image includes at least one virtual object, and the method includes:

step 101, obtaining an initial map for a virtual object, wherein the initial map has a basic pattern.

Specifically, the scene image may be an image of a game scene, the virtual object may be a virtual character in the game scene, and the initial map of the virtual object may be an initial map corresponding to a dress of the virtual object, for example, a jacket of the virtual character corresponds to one map, trousers correspond to one map, or a skirt corresponds to one map. The two parts circled in fig. 3 are the initial maps of the virtual object. The initial map has a base pattern, such as the pattern with flowers in fig. 3.

And 102, acquiring the current orientation of the virtual camera.

Specifically, the current orientation of the virtual camera refers to a user observation angle, an angle of view at which the user observes the virtual object in the game scene is different, and the current orientation of the virtual camera is different.

And 103, acquiring a target shading chartlet corresponding to the initial chartlet under the current orientation of the virtual camera, wherein the target shading chartlet is a chartlet obtained after shading treatment is carried out on the initial chartlet under the current orientation.

Specifically, for each initial map, the shading effects presented in the directions of different virtual cameras may be different, and therefore, a target shading map corresponding to the initial map in the current direction of the virtual camera is obtained, where the target shading map is a map obtained after shading the initial map in the current direction.

In one embodiment, the base pattern in the initial chartlet may be shaded to obtain shaded texture; for example, fig. 4 shows the base pattern in the initial map shown in the left margin of fig. 3, and fig. 5 shows the texture of the base pattern in fig. 4 after shading.

And fusing the texture after the halation and the base map of the initial mapping to obtain the target halation mapping.

The base map is a map obtained by removing all the details of the patterns in the initial map, and as shown in fig. 6, all other effects and details of the base map are the same as those of the initial map, except that no patterns are provided.

And 104, rendering the virtual object according to the current orientation, the target shading chartlet and the initial chartlet.

Specifically, the virtual object is rendered according to the target shading chartlet of the obtained initial chartlet facing downward at the current orientation, for example, the target shading chartlet and the initial chartlet are fused according to the current orientation, and the shading effect of the virtual object facing downward at the current orientation is displayed on the graphical user interface.

For example, FIG. 7 is an enlarged view of a portion of an area in FIG. 3, FIG. 8 is a target shading map of the initial map of FIG. 7 with the initial map facing down in a, FIG. 9 is a target shading map of the initial map of FIG. 7 with the initial map facing down in b, and FIG. 10 is a target shading map of the initial map of FIG. 7 with the initial map facing down in c.

In the method of the embodiment, an initial map for a virtual object and a current orientation of a virtual camera are obtained by including the virtual object in a scene image captured by the virtual camera, wherein the initial map has a basic pattern; and rendering the virtual object according to the observation visual angle of a user, namely the current orientation of the virtual camera, the target halation chartlet and the initial chartlet, so that the virtual object presents the halation effect under the current orientation, and the presentation effect of the virtual object is improved.

On the basis of the foregoing embodiment, in order to improve the response speed, that is, in order to quickly display the shading effect in the current orientation after the user adjusts the current orientation of the virtual camera, target shading maps of each initial map in different current orientations may be obtained in advance, and step 103 in this embodiment may be specifically implemented by:

carrying out halation treatment on the basic pattern in the initial chartlet to obtain halation texture;

acquiring a halation effect parameter of the initial chartlet in the current orientation according to the current orientation and a target normal vector; the target normal vector is obtained according to the halation texture and the vertex normal of the virtual object;

fusing the shading texture and the base map by using the shading effect parameters of the initial mapping in the current orientation to obtain a target shading mapping corresponding to the initial mapping in the current orientation of the virtual camera; the base map is a map obtained by removing the base pattern in the initial map.

Specifically, as shown in fig. 3, the circled portion is an initial chartlet, that is, a complete common chartlet with details of the basic pattern, the basic pattern in the initial chartlet is obtained to obtain the pattern shown in fig. 4, and the basic pattern is subjected to shading processing to obtain shading texture, as shown in fig. 5.

The shading process is based on the shape of the base pattern, over which shading details are spread.

In one embodiment, the brightness of the shading texture is gradually changed from the center of the shading texture to the periphery.

For example, the lightness of a vignette varies gradually within 0-1 from the center of the vignette towards the periphery.

In one embodiment, to reduce the amount of data storage, the shading texture resulting from the shading process may be black and white.

For example, vignette texture data may be stored within the alpha channel of the base map. The base map may be saved in the RGB channel of the original map.

In one embodiment, the current orientation and the target normal vector may be used for calculation to obtain a dynamic value as the vignetting effect parameter, for example, a dot product calculation is performed on the direction vector of the current orientation and the target normal vector.

Wherein the target normal vector is obtained from the vignetting texture and the vertex normal of the virtual object, when the vignetting texture is used as the normal texture.

Since the shading effect parameter is derived from the current orientation and the target normal vector, the final displayed shading effect varies with the current orientation, i.e. the angle presented to the user.

And fusing the shading texture and the base map by using the shading effect parameters of the initial mapping in the current orientation to obtain the target shading mapping with the shading effect corresponding to the initial mapping in the current orientation. For example, a Lerp function is used for the fusion process, and the shading effect parameter in the current direction is used as the parameter of the Lerp function.

The fusion processing refers to an image processing method.

In the above embodiment, the halation texture and the base map are fused by using the parameters of the halation effect of the initial chartlet in the current orientation, so as to obtain a target halation chartlet corresponding to the initial chartlet in the current orientation of the virtual camera; and further rendering the virtual object according to the observation visual angle of the user, namely the current orientation of the virtual camera, the target shading chartlet and the initial chartlet, so that the virtual object presents shading effect downwards at the current orientation, and the presenting effect of the virtual object is improved.

In an embodiment, the halo effect parameters of the initial chartlet in the current orientation are used to perform fusion processing on the halo texture and the base map, so as to obtain a target halo chartlet corresponding to the initial chartlet in the current orientation of the virtual camera, which can be implemented as follows:

adjusting the shading texture according to preset color parameters and/or brightness parameters to obtain the adjusted shading texture;

and fusing the adjusted halation texture and the base map by using the halation effect parameters of the initial mapping in the current orientation to obtain a target halation mapping corresponding to the initial mapping in the current orientation of the virtual camera.

The color parameter and/or the brightness parameter may be the same as the color parameter and/or the brightness parameter of the basic pattern in the initial map, or may be different from the color parameter and/or the brightness parameter of the basic pattern in the initial map.

The color parameter and/or the brightness parameter may be user set.

Specifically, as shown in fig. 11, the adjusted halation texture may be obtained by multiplying the halation texture data by a vector of color parameters, for example, the vector of color parameters is a four-dimensional vector including RGBA four dimensions, and then multiplying by the lightness parameter value.

And performing fusion processing on the base map and the adjusted halation texture, for example, performing fusion processing by adopting a Lerp function, wherein the parameters of the halation effect in the current downward direction are taken as the parameters of the Lerp function.

In an embodiment, step 104 may be specifically implemented as follows:

according to the current orientation, fusing the target halation mapping and the initial mapping to obtain a target mapping;

and rendering the virtual object according to the target map.

Specifically, the initial chartlet and the target shading chartlet are subjected to fusion processing by utilizing the shading effect parameters of the current orientation, and the target chartlet of the initial chartlet in the current orientation is obtained.

And performing fusion processing, namely interpolation calculation, to obtain a target map of the initial map in the current direction.

As shown in fig. 11, for example, the fusion process is performed using a Lerp function, and the halation effect parameter in the current direction is set as a parameter of the Lerp function. Whether the initial or target vignette map is displayed, or the extent to which the target vignette map is displayed, is controlled by the Lerp function.

And according to the target chartlet of the initial chartlet in the current orientation, displaying the halation effect of the initial chartlet of the virtual object in the current orientation of the virtual camera on a graphical user interface when presenting the initial chartlet to a user.

In the above embodiment, dynamic alternation of the target map and the initial map with shading effect is realized, and the pattern details on the virtual character clothes are different under different orientations of the virtual camera, i.e. different user observation visual angles, so as to achieve the effect that the original pattern and the ink shading dynamically change along with the user observation visual angles.

In one embodiment, the vignetting effect parameter for the current orientation may be obtained by:

adding the normal texture corresponding to the halation texture and the vertex normal of the virtual object to obtain a target normal vector;

and performing point multiplication on the current orientation and the target normal vector to obtain a halation effect parameter corresponding to the current orientation.

Specifically, as shown in fig. 12, the vector of the normal texture of the shading texture and the vector of the vertex normal of the virtual object are added, normalization processing is performed to obtain a target normal vector, and then the vector of the direction corresponding to the current orientation is respectively subjected to point multiplication with the target normal vector to obtain shading effect parameters of the initial chartlet in the current orientation.

In the above embodiment, the shading effect parameter for determining the variation of the shading effect is obtained by using the current orientation of the virtual camera and the target normal direction of the shading texture, wherein the target normal direction is the calculated value of the texture normal and the vertex normal, and the shading effect that the clothing pattern of the virtual object varies with the variation of the viewing angle is realized.

In the above embodiment, along with the difference of the observation angle of the user, that is, the current orientation, the dress pattern of the virtual object presents different shading effects, that is, the pattern of the virtual character has a dynamic change effect in different orientations, and has a water and ink shading effect, thereby improving the dress pattern change effect.

In an embodiment, the method of this embodiment further includes:

responding to the clothing change operation of the virtual object, and acquiring an initial chartlet of the virtual object after clothing change;

acquiring a target halation chartlet corresponding to the initial chartlet after the clothes change at the current orientation of the virtual camera;

and rendering the virtual object according to the current orientation, the target shading charm and the initial charm after the clothing change.

Specifically, the user may also change the clothing of the virtual object, for example, change the pattern, color, and the like of the clothing, perform clothing changing operation, for example, set an operation control on the graphical user interface, the user operates the operation control, and in response to the clothing changing operation on the virtual object, obtain an initial chartlet of the virtual object after clothing changing; for example, by changing the base pattern in the initial map, the details of the pattern can be in any form, such as a change in the details of the base pattern, or simply a change in the color parameter and/or brightness parameter.

The changed basic pattern can be customized by a user or selected by the user according to a pattern provided by the system.

Acquiring a target halation chartlet corresponding to the initial chartlet after the clothes change at the current orientation of the virtual camera; the generation process of the target shading map is similar to that of the target shading map in the previous embodiment, and is not described again here. The corresponding base map of the initial mapping and the initial mapping after the clothes change is not changed, and only the shading treatment is needed to be carried out on the basic pattern, and the obtained shading texture, the initial mapping and the base map are subjected to fusion treatment.

And then rendering the virtual object according to the current orientation, the target shading charm and the initial charm after the clothing change, and displaying the shading effect of the virtual object in the orientation on a graphical user interface.

In the above embodiment, the dynamic change of the patterns on the virtually tinned clothes is realized, the new patterns of the clothes can be selected according to actual requirements, the new patterns only need to be subjected to shading treatment, the initial chartlet and shading texture after the shading treatment can be utilized for fusion treatment, complex flows such as model replacement and the like are not needed, the manufacturing cost is greatly saved, and the complexity is reduced.

In an embodiment, changes may also be made to the overall apparel of the virtual object, such as by model replacement, or to portions of the apparel of the virtual object, such as by way of a replacement map.
