Fig. 1 is a schematic flowchart of an image generation method provided in an embodiment of the present disclosure, where the embodiment of the present disclosure is applicable to a situation of generating an image, and the method may be executed by an image generation apparatus, and the apparatus may be implemented in the form of software and/or hardware, and optionally implemented by an electronic device, and the electronic device may be a mobile terminal, a PC terminal, or a server.

As shown in fig. 1, the method includes:

s110, at least one initial special effect map is obtained based on the triggering operation of the user.

The initial special effect map may be a pre-constructed special effect map with a set size, and may be integrated into a pre-developed special effect resource package. For example, in a makeup application scenario, the initial effect map may be a makeup map related to a face, and may include an eye makeup map, a lip makeup map, and the like, for example: eyelash, blush, eyebrow, and eye etc.

In this embodiment, the manner of obtaining at least one initial special effect map based on the trigger operation of the user may be: loading special effect resources based on resource loading operation triggered by a user to generate a special effect resource panel; receiving at least one special effect resource selected by a user; at least one initial special effects map is obtained based on at least one special effects resource.

The special effect resource panel is used for displaying a plurality of special effect resources, and the special effect resources comprise initial special effect maps and rendering information. In this embodiment, a special effect editing interface is provided in a special effect generation tool or a special effect generation Application program (APP), and a user clicks a resource loading button in the special effect editing interface to load a special effect resource, so as to generate a special effect resource panel, where the special effect resource includes an initial special effect map and rendering information. A plurality of special effect resources are displayed in the special effect resource panel for selection by a user. The user selects at least one special effects resource in the special effects resource panel, thereby extracting at least one initial special effects map from the user selected special effects resource. In the application scene, by taking the generation of a makeup image as an example, a makeup tool or a makeup APP provides a makeup editing interface, and in the makeup editing interface, a user clicks a resource loading button in the makeup editing interface to load a makeup resource, so that a makeup resource panel is generated, and the makeup resource can comprise an initial makeup map and rendering information. And a plurality of cosmetic resources are displayed in the cosmetic resource panel for the user to select. The user selects at least one makeup resource in the makeup resource panel, thereby extracting at least one initial makeup map from the makeup resource selected by the user. Exemplarily, fig. 2 is an exemplary diagram of a makeup editing interface in the present embodiment, as shown in fig. 2, a lower half part of the interface is a makeup panel, and a makeup map 1, a makeup map 2, and a makeup map N are displayed in the makeup panel; rendering information 1, rendering information 2, … …, and rendering information M. The upper part of the interface is used for displaying a special effect image rendered based on the makeup resources selected by the user. In this embodiment, at least one initial special effect map is obtained based on a trigger operation of a user in the special effect tool, so that convenience in generating a special effect image can be improved.

S120, cutting the effective content area in the at least one initial special effect chartlet to obtain at least one target special effect chartlet.

The effective content area may be an area formed by pixels having actual pixel information. In this embodiment, the initial special effect map may be a makeup map, where an area having makeup is an effective content area and other areas are ineffective areas. The target special effect map is a map obtained by cutting out an effective content area in the initial special effect map, and the size of the target special effect map is smaller than that of the initial special effect map.

In this embodiment, the manner of obtaining at least one target special effect map by clipping the effective content area in at least one initial special effect map may be: extracting the transparency of pixel points in at least one initial special effect chartlet; determining an effective content area based on the transparency; and forming at least one target special effect map according to the effective content area.

Wherein, the transparency is stored in a setting channel in the initial special effect map, and the setting channel may be an alpha channel. The transparency can be any value between 0 and 1, if the transparency value is 0, the pixel point is represented to be completely transparent, and if the transparency value is more than 0, the pixel point is represented to be incompletely transparent. The effective content area may be an area formed by pixels having a transparency other than 0. The effective content area may be an irregularly shaped area.

Specifically, the manner of extracting the transparency of the pixel point in at least one initial special effect map may be: and traversing pixel points in the initial special effect maps for each initial special effect map, and extracting the transparency of the traversed pixel points stored in an alpha channel.

Specifically, the manner of determining the effective content area based on the transparency may be: and deleting the pixel points with the transparency equal to the first set value, and reserving the pixel points with the transparency greater than the first set value to obtain an effective content area.

Wherein the first set value may be any value between 0-0.2, for example set to 0.1. In this embodiment, if the transparency of the pixel point in the traversal initial special effect map is less than or equal to the first set value, the pixel point is deleted, and if the transparency of the pixel point in the traversal initial special effect map is greater than the first set value, the pixel point is retained. For example, fig. 3a to 3c are exemplary diagrams of the target special effect map in the present embodiment, as shown in fig. 3a, the target special effect map is an "eye shadow" special effect, as shown in fig. 3b, an "eye line special effect", as shown in fig. 3c, an artistic word special effect. In this embodiment, the effective content area in the initial special effect map is extracted based on the transparency of the pixel points, so that the image clipping efficiency can be improved.

S130, at least one target special effect map is fused with the original virtual image map to obtain a target virtual image map.

The original avatar map may be a surface map of the 3D avatar, and no special effect information is added to the original avatar map. For example a surface map of the face of the 3D avatar. Exemplarily, fig. 4 is an exemplary view of an original avatar map in the present embodiment, as shown in fig. 4, which is not drawn with any makeup.

In this embodiment, the process of fusing at least one target special effect map and the original virtual image map may be understood as follows: pixel values are sampled from at least one target special effect map, and the pixel values in the original avatar map are replaced with the sampled pixel values, thereby obtaining a target avatar map.

Specifically, the process of fusing at least one target special effect map with the original virtual image map to obtain the target virtual image map may be: determining the position information of a set boundary point corresponding to at least one target special effect map respectively; establishing a position corresponding relation between at least one target special effect map and an original virtual image map based on the position information of the set boundary point; and fusing at least one target special effect map and the original virtual image map based on the position corresponding relation to obtain a target virtual image map.

And setting boundary point position information as position information of the set boundary point of the target special effect map in the initial special effect map. The set boundary points may be two vertices of the target special effect map, and the set boundary point position information may be determined by a minimum UV abscissa x1, a minimum UV ordinate y1, a maximum UV abscissa x2, and a maximum UV ordinate y2 of the target special effect map (or the effective content area) in the initial special effect map. The coordinates of one vertex are represented as (x 1, y 1) and the coordinates of the other vertex are represented as (x 2, y 2).

In this embodiment, the original avatar map and the original avatar map have the same size, and the target avatar map is obtained by cutting the original avatar map, so that the target avatar map and the original avatar map have different sizes, i.e., pixels do not have a one-to-one correspondence, and therefore, a correspondence between pixels of the target avatar map and pixels of the original avatar map needs to be established. The UV coordinates of the target special effect map for which two vertices are in the target special effect map are (0,0) and (1,1), respectively, and their coordinates in the initial special effect map are (x 1, y 1) and (x 2, y 2). Since the original avatar-map is the same as the initial special effect-map, it can be understood that (0,0) and (1,1) in the target special effect-map correspond to (x 1, y 1) and (x 2, y 2) in the original avatar-map, i.e., (0,0) and (x 1, y 1), (1,1) and (x 2, y 2). Thereby, the position corresponding relation between at least one target special effect map and the original virtual image map can be established based on the vertex position information. The position correspondence can be expressed as: UV coordinates of the target special effect map = (UV coordinates of the original avatar map- (x 1, y 1))/((x 2, y 2) - (x 1, y 1)).

Specifically, the process of fusing at least one target special effect map and the original avatar map based on the position correspondence may be: for the pixel points in the original virtual image chartlet, determining corresponding sampling points of the pixel points in the target special effect chartlet according to the position corresponding relation; and sampling the pixel values of the sampling points, and replacing the pixel values of the pixel points with the sampled pixel values.

And the sampling points are corresponding pixel points of the pixel points in the original virtual image chartlet in the target special effect chartlet. In this embodiment, first, the UV coordinate of a pixel point in an original virtual image map is obtained, and then the UV coordinate is substituted into an expression of a position correspondence to obtain the UV coordinate of a sampling point of the pixel point in a target special effect map, so that a pixel value is adopted from the target special effect map according to the UV coordinate, and finally, the pixel value of the pixel point is replaced with the pixel value obtained by sampling.

Specifically, the manner of determining the corresponding sampling point of the pixel point in the target special effect map according to the position correspondence relationship may be: acquiring first position information of a pixel point in an original virtual image chartlet; and determining second position information of the pixel points at corresponding sampling points of the target special effect chartlet according to the position corresponding relation and the first position information.

The first position information and the second position information are both characterized by UV coordinates, the first position information can also be called first UV coordinates, and the second position information can be called second UV coordinates. In this embodiment, the first UV coordinate is substituted into the expression of the position correspondence, and a second UV coordinate of a sampling point corresponding to the pixel point in the target special effect map is obtained. In this embodiment, the sampling points corresponding to the pixel points in the target special effect map are determined based on the position correspondence, and the target special effect map can be accurately fused to the corresponding positions in the original virtual image map.

Optionally, the mode of replacing the pixel value of the sampling point with the pixel value of the pixel point may be: if the second position information is within the set threshold range, replacing the pixel value of the pixel point with the pixel value of the sampling point at the second position information; and if the second position information is out of the set threshold range, keeping the pixel value of the pixel point unchanged.

Wherein the set threshold range may be a range between 0 and 1, and the second position information being within the set threshold range may be understood as the UV abscissa and the UV ordinate being both within the set threshold range. The second position information being outside the set threshold range may be understood as the UV abscissa being outside the set threshold range, or the UV ordinate being outside the set threshold range, or both the UV abscissa and the UV ordinate being outside the set threshold range. In this embodiment, if the second position information is within the set threshold range, it indicates that a corresponding sampling point exists in the target special effect sticker for a pixel point in the initial virtual image sticker, and the pixel value of the pixel point is replaced with the pixel value of the sampling point located in the second position information. If the second position information is outside the set threshold range, it indicates that the pixel point in the initial virtual image chartlet does not have a corresponding sampling point in the target special effect chartlet, that is, the pixel is understood to be beyond the range of the area where the target special effect chartlet is located, and the pixel value of the pixel point is kept unchanged. Exemplarily, fig. 5 is an exemplary diagram of a target avatar map in the present embodiment, as shown in fig. 5, the target special effect maps of fig. 3 a-3 c are fused to corresponding positions in the original avatar map of fig. 4. In this embodiment, whether to replace the pixel value of the pixel point in the initial avatar map is determined according to whether the second position information is within the set threshold range, so that the sampling accuracy can be improved.

S140, rendering the target virtual image map to obtain the target virtual image map.

In this embodiment, the rendering of the target avatar map may be performed in a manner of obtaining the target avatar map: obtaining a rendering sequence of at least one target special effect map; and rendering the target virtual image map based on rendering sequence to obtain the target virtual image map.

Wherein the rendering order of the target special effect map may be understood as the rendering order of the initial special effect map. The rendering order may be predetermined by a developer, and the rendering order may be obtained by obtaining at least one initial special effect map selected by a user. And rendering the special effect areas in the target virtual image chartlet in sequence based on the rendering sequence after the rendering sequence is obtained. In the application scene, because the special effect chartlet can be a makeup chartlet, in the actual application scene, the superposed precedence position relationship needs to be determined between makeup with an overlapped relationship, and therefore, the rendering sequence of each target special effect chartlet needs to be determined when the target virtual image chartlet is rendered. In the embodiment, the target virtual image map is rendered based on the rendering sequence, so that the dressing display sequence is correct, and the display effect is improved.

In this embodiment, when rendering the target avatar map, rendering information of each pixel point needs to be determined, and the pixel points in the target avatar map are rendered based on the rendering information.

Specifically, the method for rendering the target avatar map to obtain the target avatar may be: and rendering the target virtual image map based on rendering information corresponding to the at least one initial special effect map to obtain the target virtual image map.

Wherein the rendering information includes at least one of: color information, material information, normal information, and illumination information. The texture information and the illumination information may be stored in the form of an image, the texture information being stored in an RGB channel of the image, and the illumination information being stored in an Alpha channel of the image. The normal information may also be stored in the form of an image, the RGB channels of which store the three components of the normal information, respectively. In this embodiment, the texture of the pixel points is calculated based on the texture information. And performing normal calculation on the pixel points based on the normal information, performing illumination calculation on the pixel points based on the illumination information, and assigning the color information to the pixel points. Exemplarily, fig. 6 is a schematic view of a target avatar diagram in the present embodiment, as shown in fig. 6, a variety of makeup is fused into an initial avatar. In the embodiment, the rendering information is used for rendering the target virtual image map, so that the diversity of the target virtual image map can be improved, and the display effect is enriched.
