[0002] When multimedia is edited, editing effects are usually displayed through stickers, which are usually displayed through grids. When stickers are animated, the sticker content is limited to a grid. When the sticker content is animated, it may be truncated, resulting in poor sticker animation display effects.

[0003] At present, in order to solve the problem of truncation of texture content when texture animation is displayed, two rendering channels are used to implement the texture animation. That is to say, multiple cameras are used to render the scene. However, this method requires additional rendering channels, which requires a large amount of calculation and increases the performance burden. Summary of the invention

[0034] Figure 1 A flow chart of an image processing method provided in an embodiment of the present disclosure is applicable to situations when a target object is displayed, such as situations when objects such as text stickers / picture stickers are displayed. The method can be executed by an image processing device, which can be implemented in the form of software and / or hardware, and optionally, by an electronic device, which can be a mobile terminal, a PC or a server, etc.

[0035] like Figure 1 As shown, the method includes:

[0036] S110: In response to a display operation on a target object, determine an initial rendering area of ​​the target object.

[0037] In order to solve the technical problem that the target object is truncated when displayed through a texture animation, and the computational problem that multiple rendering channel processing leads to large computational complexity and poor rendering performance, the disclosed embodiment provides a technical solution for texture rendering through a single rendering channel. In general, the initial rendering area of ​​the target object is first enlarged, a texture is constructed in the enlarged rendering area, and then the texture is adjusted to the initial rendering area, so that the texture will not be affected by the fixed mesh size, and the texture is prevented from being truncated by the mesh. At the same time, the single channel has low computational complexity, which can improve rendering performance.

[0038] Optionally, the target object may be any object that can be displayed by a sticker. Taking the field of multimedia file processing as an example, the target object is text or an image, wherein the text may be text of any font, any size, and any shape, and the image may be a static image, a virtual reality (VR) object, an augmented reality (AR) object, etc.

[0039] For example, when a user renders text and needs to display it through a texture, the target object is the text; for another example, when a user renders a video image frame or an image or a VR / AR object and needs to display it through a texture, the target object is the corresponding image.

[0040] In this embodiment, the initial rendering area of ​​the target object can be understood as the original area when rendering the target object. Taking the existing texture display as an example, the texture of the target object is displayed in a fixed mess, and the fixed mess area is used as the initial rendering area of ​​the target object.

[0041] S120: Map an initial rendering area of ​​the target object to a target rendering area, and determine a position mapping relationship between the initial rendering area and the target rendering area.

[0042] In order to avoid the fixed initial rendering area being unable to render the target object completely, and the map showing the truncated target object, in this embodiment, the rendering area of ​​the target object is first enlarged to the target rendering area, the initial rendering area is mapped to the target rendering area, and the target object is rendered in the enlarged target rendering area, so that the rendered map is not limited by the size of the initial rendering area and can render the complete target object. Optionally, the target rendering area is an area that includes the initial rendering area and is larger than the initial rendering area. When determining the target rendering area, it is sufficient as long as the above conditions are met.

[0043] Among them, mapping the initial rendering area to the target rendering area can be understood as mapping the area coordinates in the initial rendering area to the area coordinates in the target rendering area, and the position mapping relationship between the initial rendering area and the target rendering area can also be understood as the position mapping relationship between the corresponding coordinate points in the initial rendering area and the target rendering area.

[0044] Assuming that the target rendering area is a square centered at the center of the initial rendering area and having a side length that is twice the side length of the initial rendering area, mapping the initial rendering area to the target rendering area can be understood as mapping the coordinate points in the initial rendering area to the target rendering area. Taking the upper left corner point of the initial rendering area as an example, it is mapped to the upper left corner point of the target rendering area. Based on the coordinate mapping relationship, the position mapping relationship between the initial rendering area and the target rendering area can be determined.

[0045] The target rendering area can be set according to actual conditions. For example, the target rendering area can be set to a fixed area, or can be set to an area adjusted based on the application scenario. The larger the target rendering area, the more it can ensure that the rendered map will not be truncated.

[0046] In one implementation, a fixed area can be set as the target rendering area based on empirical values. For example, based on historical rendering operations, a fixed area that meets the rendering requirements of the target object in the historical rendering operations is set as the target rendering area. Alternatively, the target rendering area can be directly set to the size of the display area to simplify the setting of the target rendering area and ensure that the map is not truncated to the greatest extent, such as using the display area of ​​the map display device as the target rendering area.

[0047] In another implementation, the target rendering area can be dynamically set based on the current target object or the display device of the map. For example, based on the size of the current target object and the animation requirements, an area that satisfies the animation display of the current target object can be set as the target rendering area; the setting of the target rendering area can also be simplified, and the display area of ​​the display device of the map can be directly used as the target rendering area.

[0048] In an embodiment of the present disclosure, before mapping the initial rendering area of ​​the target object to the target rendering area, the method further includes:

[0049] Acquire an initial grid area of ​​the target object as the initial rendering area;

[0050] The target rendering area is set based on a preset rule and the initial rendering area, wherein the target rendering area includes an initial rendering area and an extended rendering area.

[0051] Optionally, the mesh area of ​​the target object can be directly used as the initial rendering area, the size of the extended rendering area can be preset, and the initial rendering area and the preset extended rendering area can be merged to obtain the target rendering area. The size of the extended rendering area can be set to a fixed value; the extended rendering area can also be set to a value related to the initial rendering area, such as setting the extended rendering area to be a region vertically extended outward by k coordinates based on the boundary of the initial rendering area, where k can be a set value.

[0052] It should be noted that the target rendering area may be set in any one of the above methods or in any combination thereof, and is not limited here.

[0053] S130: Render the target object in the target rendering area to obtain an initial object map.

[0054] In this embodiment, after determining the target rendering area, the target rendering area is used as the rendering area of ​​the target object, and a rendering map of the target object in the target rendering area is obtained as the initial object map. The rendering operation of the target object can refer to the rendering operation in the prior art, and is not limited here, as long as the rendering of the target object can be achieved.

[0055] S140. Based on the position mapping relationship, map the initial object map from the target rendering area to the initial rendering area to obtain a target object map, and display the target object based on the target object map.

[0056] It can be understood that the initial object map is obtained by rendering the target object in the target rendering area. In order to accurately display the target object in the initial rendering area, it is necessary to map the initial object map obtained by rendering the target rendering area back to the initial rendering area to obtain a target object map that conforms to the initial rendering area. In the above steps, after mapping the initial rendering area to the target rendering area, a position mapping relationship between the initial rendering area and the target rendering area can be obtained. Based on the position mapping relationship, the initial object map can be mapped back to the initial rendering area to obtain the target object map.

[0057] In an embodiment of the present disclosure, mapping the initial object map from the target rendering area to the initial rendering area based on the position mapping relationship to obtain the target object map further includes:

[0058] Based on the position mapping relationship, determining a texture mapping relationship in which the initial object texture is mapped from the target rendering area to the initial rendering area;

[0059] According to the texture mapping relationship, the initial object texture is mapped from the target rendering area to the initial rendering area to obtain the target object texture.

[0060] It can be understood that the position mapping relationship between the initial rendering area and the target rendering area represents the coordinate point correspondence relationship between the initial rendering area and the target rendering area, and the initial object map is mapped from the target rendering area to the initial rendering area, which needs to be mapped based on the coordinate point correspondence relationship between the target rendering area and the initial rendering area. Based on this, the mapping relationship (i.e., the map mapping relationship) between the target rendering area and the initial rendering area can be determined based on the position mapping relationship between the initial rendering area and the target rendering area, and then the initial object map is mapped from the target rendering area to the initial rendering area based on the map mapping relationship to obtain the target object map.

[0061] Among them, the texture mapping relationship can be obtained by combining the position mapping relationship and the interpolation characteristics of texture rendering.

[0062] In an embodiment of the present disclosure, determining, based on the position mapping relationship, a texture mapping relationship in which the initial object texture is mapped from the target rendering area to the initial rendering area includes:

[0063] Based on the position mapping relationship, determining initial area position parameters of the initial rendering area in a world coordinate system;

[0064] The texture mapping relationship is determined based on the initial region position parameters and the target region position parameters of the target rendering region.

[0065] It can be understood that the mapping relationship of the target rendering area to the initial rendering area represents the coordinate point mapping relationship of the target rendering area to the initial rendering area. Based on this, the mapping relationship can be determined according to the area coordinates of the target rendering area and the area coordinates of the initial rendering area. Among them, the area coordinates of the target rendering area can be determined by the target rendering area position parameters, and the area coordinates of the initial rendering area can be determined by the initial rendering area position parameters. The target rendering area position parameters are known values ​​and can be obtained by setting the target rendering area. The initial rendering area position parameters can be determined by the position mapping relationship. Both the initial area position parameters and the target area position parameters are parameters in the world coordinate system.

[0066] Among them, the initial area position parameter can be the position information or size information of the initial rendering area, such as the area position of the initial rendering area, the area size of the initial rendering area and other parameters. Correspondingly, the target area position parameter can be the position information or size information of the target rendering area, such as the area position of the target rendering area, the area size of the target rendering area and other parameters.

[0067] In one embodiment of the present disclosure, the initial region position parameter includes vertex position information of the initial rendering region in a world coordinate system, and determining the texture mapping relationship based on the initial region position parameter and the target region position parameter of the target rendering region includes:

[0068] Determine an initial area size parameter of the initial rendering area based on vertex position information of the initial rendering area in a world coordinate system;

[0069] The texture mapping relationship is determined based on the initial region size parameter and the target region position parameter.

[0070] When the initial region position parameter is the vertex position information (coordinates) of the initial rendering region in the world coordinate system, the length and width of the initial rendering region can be calculated based on the vertex position coordinates, thereby obtaining the initial region size parameter of the initial rendering region. Exemplarily, assuming that the vertex position coordinates of the initial rendering region in the world coordinate system are (1,2), (2,2), (1,1) and (2,1), respectively, the length and width of the initial rendering region are 1, that is, the initial region size parameters are: length is 1, width is 1.

[0071] After the initial region size parameters are determined, a mapping relationship between the target region position parameters and the initial region size parameters is used as a texture mapping relationship.

[0072] In an implementation manner of the present disclosure, determining the initial region position parameters of the initial rendering region in the world coordinate system based on the position mapping relationship includes:

[0073] Based on the position mapping relationship, determining a first coordinate mapping relationship in which the boundary point of the initial rendering area is mapped from the target rendering area to the initial rendering area;

[0074] constructing an auxiliary point based on the position mapping relationship and the vertex, and determining a second coordinate mapping relationship of the auxiliary point from the target rendering area to the initial rendering area;

[0075] According to the first coordinate mapping relationship and the second coordinate mapping relationship, vertex position information of the initial rendering area in the world coordinate system is determined, and the initial area position parameters are determined according to the vertex position information.

[0076] It can be understood that the target object is rendered in the target rendering area, and the initial object map obtained has the characteristics of the uv map. When the map is rendered, the interpolation process from the vertex shader to the fragment shader during the rendering process has the interpolation characteristics. The equation can be constructed based on the above two characteristics, and the constructed equation is solved to obtain the area size parameters of the initial rendering area. In other words, when determining the initial area position parameters, the calculation can be combined based on the mapping relationship and the interpolation characteristics. Taking the mapping of any boundary point of the initial rendering area as an example, the first coordinate mapping relationship of the vertex from the target rendering area to the initial rendering area can be determined based on the position mapping relationship and the interpolation characteristics to obtain the first equation. Then construct the auxiliary point, determine the second coordinate mapping relationship of the auxiliary point from the target rendering area to the initial rendering area, and obtain the second equation. Then, the first equation and the second equation are combined to obtain the vertex position information of the initial rendering area in the world coordinate system, thereby determining the initial area position parameters. Among them, the construction of the auxiliary point can be constructed based on the position mapping relationship.

[0077] Optionally, taking the horizontal coordinate of the left vertex of the initial rendering area as x and the horizontal coordinate of the right vertex as x1 as an example, the first coordinate mapping relationship of any boundary point from the target rendering area to the initial rendering area is determined based on the position mapping relationship and the interpolation characteristics, and the first equation obtained is m=(1-u)x1+ux, where m is the horizontal coordinate of the boundary point and u is the size parameter of the initial object map; the second coordinate mapping relationship of the auxiliary point from the target rendering area to the initial rendering area is n=(1-u)-x1+ux, where n is the horizontal coordinate of the auxiliary point and u is the size parameter of the initial object map. The first equation and the second equation are combined to obtain the vertex position coordinates of the initial rendering area, thereby obtaining the area size parameter of the initial rendering area.

[0078] S140. Based on the position mapping relationship, map the initial object map from the target rendering area to the initial rendering area to obtain a target object map, and display the target object based on the target object map.

[0079] After the position mapping relationship is determined, the coordinates of the initial object map in the target rendering area are mapped to the coordinates of the initial rendering area based on the position mapping relationship to obtain the target object map, and the target object map is displayed.

[0080] Optionally, after the target object map is adjusted to the initial rendering area, texture sampling may be performed on the target object map to obtain an object texture map of the target object, and the object texture map may be displayed in the display area.

[0081] The method of performing texture sampling on the target object map may refer to the texture sampling method in the prior art, and is not limited here.

[0082] On the basis of the above solution, the solution provided by the embodiment of the present disclosure also includes:

[0083] In response to a dynamic display operation on a target object, position information of the target object map in a world coordinate system is adjusted based on a dynamic display rule of the dynamic display operation, and the target object is dynamically displayed based on the adjusted target object map.

[0084] After obtaining the target object map, when the user operates to dynamically display the target object, the positions of some coordinate points in the target object map can be adjusted based on the dynamic display rules of the dynamic display, and the target object map after the coordinate point positions are adjusted can be displayed. Taking the up and down floating dynamic display as an example, the vertical coordinates of the coordinate points in the target object map can be dynamically adjusted within a set time period to display the target object map that floats up and down. Based on the technical solution of the embodiment of the present disclosure, when the target object map is animatedly displayed, the position information of the target object in the target object map can be adjusted based on the animation to realize the animated display of the map, and the target object map will not be truncated during the animated display.

[0085] The technical solution of the disclosed embodiment determines an initial rendering area of ​​the target object in response to a rendering operation on the target object; enlarges the initial rendering area of ​​the target object to a target rendering area, renders the target object in the target rendering area to obtain an initial object map; maps the initial object map to the initial rendering area to obtain a target object map; performs texture sampling on the target object map to obtain an object texture map, and displays the object texture map. By first enlarging the rendering area of ​​the target object and mapping it to the target rendering area, and then mapping the initial object map drawn in the target rendering area back to the target rendering area for display, it is achieved that only a single rendering channel is required to achieve non-truncated map display, and the technical problems of large computational complexity and poor performance when rendering with multiple rendering channels are solved.

[0086] Taking the target object as text as an example, the display of text stickers is illustrated.

[0087] Before text model is textured, it is necessary to convert the text model to clip space, implement text texture in clip space, and display the texture in screen space. Optionally, the mesh can be converted from model space to clip space by multiplying uMVP in the rendering pipeline. It should be noted that in clip space, the coordinates of any coordinate axis are always limited to [-1, 1].

[0088] After converting the mesh to clip space, the mesh is processed. Specifically:

[0089] (1) Use UV information to map the mesh area of ​​the text model to the screen area.

[0090] Figure 2a FIG. 1 is a schematic diagram of a region expansion provided by an embodiment of the present disclosure. Figure 2aAs shown, the mesh area of ​​the text model (i.e., the initial rendering area) is a rectangular area composed of (0,0) and (1,1), and the screen area is a rectangular area composed of (-1,-1) and (1,1). Expanding the mesh area of ​​the text model to the screen area is equivalent to mapping (0,0) and (1,1) to (-1,-1) and (1,1), that is, clip_space = uv*2-1.

[0091] (2) Calculate the uv of the current vertex through the inverse of uMVP.

[0092] (3) Calculate the size of the original text model through simultaneous equations.

[0093] The specific calculation method may refer to the method of calculating the area position parameters of the initial rendering area in the above embodiment, which will not be described in detail here.

[0094] (4) Obtain the target UV position based on the size of the original text model.

[0095] If the width of the original text model is set to width and the height is set to height, the target uv position can be calculated as follows:

[0096] uv.x-=(x.x+yx)*0.5;

[0097] uv.y+=(x.y+yy)*0.5;

[0098] uv.x / =(width)*0.5;

[0099] uv.y / =(height)*0.5;

[0100] uv = uv * 0.5 + 0.5;

[0101] Among them, x and y are the vertex position coordinates of the original text model (i.e., the initial rendering area).

[0102] (5) Adjust the map position based on the target UV position and display it after texture sampling.

[0103] Figure 2b It is a schematic diagram of the text texture display effect of a single rendering channel in the prior art; Figure 2c Schematic diagram of a text sticker display effect provided by an embodiment of the present disclosure. Figure 2b and Figure 2c As shown, the texture rendering method provided by the embodiment of the present disclosure avoids the truncation of the texture.

[0104] The technical solution of the disclosed embodiment realizes rendering of a complete texture by using UV to convert the initial mesh area into a full-screen mesh in a single rendering channel, and determines the correct UV value in the full-screen mesh by using simultaneous equations to realize accurate display of the complete texture.
