[0036] Specifically, this embodiment will be described from the perspective of a model rendering device, which can be integrated into an electronic device, that is, the model rendering method of the embodiment of the present application can be executed by an electronic device, and optionally, the electronic device can include: a terminal device.

[0037] The model rendering method provided in the embodiment of the present application can be applied to a model rendering system. The model rendering system may include a player terminal device and a server, and the terminal may be a device including both receiving and transmitting hardware, that is, a device having receiving and transmitting hardware capable of performing two-way communication on a two-way communication link. The player terminal device and the server may perform two-way communication via a network.

[0038] Optionally, the server may be an independent server, or a server network or server cluster composed of servers, including but not limited to a computer, a network host, a single network server, a plurality of network server sets or a cloud server composed of multiple servers. The cloud server is composed of a large number of computers or network servers based on cloud computing.

[0039] The following is a detailed description in conjunction with the accompanying drawings. In this embodiment, the execution subject is a terminal device as an example. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Although the logical order is shown in the flowchart, in some cases, the steps shown or described can be performed in an order different from that shown in the accompanying drawings.

[0040] The model rendering method of this embodiment obtains the target model to be rendered; obtains a texture map, wherein the texture map includes at least two map areas, and each map area is provided with a material image that needs to be presented on the target model; obtains material depth information corresponding to each map area, wherein at least two material depth information are different; based on the shooting perspective vector of the virtual camera of the target model and the material depth information of each map area, the material image of each map area is rendered on the target model, thereby reducing the resources consumed when rendering the depth effect of the model.

[0041] Please refer to Figure 1 Taking a terminal as an example, this embodiment provides a model rendering method. The specific process of the model rendering method can be as follows: Steps 101 to 104, wherein:

[0042] Step 101: Obtain a target model to be rendered.

[0043] The target model is a model to be rendered with a depth effect, and the target model serves as a visual carrier to present the depth effect.

[0044] Exemplarily, the above-mentioned target model can be a mask model that needs to render the depth effect of the starry sky, that is, the depth of the starry sky is shown on the mask model; the above-mentioned target model can also be a teacup model, pet model, etc. that needs to render the depth effect of a specific object. The specific setting can be based on demand and is not limited here.

[0045] It should be noted that, in order to achieve the depth effect of the starry sky, in the game scene, the stars can be divided into multiple different levels, and the stars in each level are at a different distance from the player to form the depth effect of the starry sky.

[0046] In some embodiments, the terminal can use modeling software and use modeling commands to create a model patch body that needs to be expressed by parallax, that is, the above-mentioned target model. The terminal uses the modeling software to generate and modify patch wiring, and uses modeling commands such as clipping, scaling, and rotation to create a model patch body that needs to be expressed by parallax.

[0047] Specifically, the above-mentioned modeling software includes but is not limited to 3Dmax, maya and other modeling software.

[0048] For example, Figure 2 As shown, the target model can be Figure 2 The mask model in Figure 2 The red model area on the front of the helmet model is the mask model.

[0049] In some embodiments, in order to facilitate the rendering of the target model, the terminal may perform UV expansion processing on the target model to be rendered after obtaining the target model to be rendered, so as to cause the model UV of the target model to be tiled between quadrants 0 and 1, to obtain a two-dimensional plane image of the target model, so as to cause the material image in the texture map to be presented on the target model based on the two-dimensional plane image of the target model, thereby realizing the rendering of the target model.

[0050] Specifically, the terminal may use a UV unfolding tool in the modeling software to perform UV unfolding processing on the target model.

[0051] For example, Figure 3 As shown, the target model is set as the mask model, and the terminal performs UV processing on the mask model to obtain Figure 3 An illustration of the circular area in Figure 3 The circular area in corresponds to the two-dimensional plane diagram of the mask model. Figure 3 The 2D plan view in also shows the tiled mesh of the mask model.

[0052] Step 102: Acquire a texture map, wherein the texture map includes at least two map regions, and each map region is provided with a material image that needs to be presented on the target model.

[0053] Among them, the area of ​​the mapping area in the above-mentioned texture map can be set equally, or it can be set non-equally based on the material image or other factors. Moreover, the material images set in different material areas can be the same or different. The specific setting can be made according to the needs and is not limited here.

[0054] In this embodiment, the terminal provides a texture map including multiple map areas, thereby achieving the effect of layered control of multiple material images using only one map. For example, when controlling multiple material images in layers, parallax offset can be achieved in layers to form a depth effect, thereby greatly saving resource consumption.

[0055] For example, Figure 4 As shown in the figure, when setting the current need to render the starry sky depth effect on the target model, you can Figure 4 The texture map shown is divided into four equal areas, each of which is set with a corresponding material image. Figure 4 As can be seen in Figure 1, each material image is a material image related to the starry sky, such as Figure 4 The material image in the texture area in the upper left corner is an aircraft, and the material images in the other three texture areas are star images of different styles.

[0056] In some embodiments, the texture map may be obtained by making an initial map, or may be obtained from a preset storage space to meet preset map requirements, etc. The specific setting can be made according to the requirements and is not limited here.

[0057] Specifically, the terminal can obtain an initial map and partition indication parameters for the initial map. Then, the terminal can divide the initial map into at least two map areas based on the partition indication parameters. Finally, the terminal can obtain at least two material images to be presented on the target model, and respectively set the at least two material images in the map areas to obtain the texture map.

[0058] The initial map may be a blank map, such as a 512*512 map, and the terminal may partition the initial map by using image processing software such as PS.

[0059] Among them, the above-mentioned partition indication parameters are used to indicate the partitioning status of the initial map, such as the number of partitions, based on which the initial map can be divided into a corresponding number of map areas, and the partition ratio, that is, based on which the initial map can be divided into a corresponding ratio of map areas.

[0060] It should be noted that the format of the texture map may vary depending on the image processing software used to process the initial map. For example, the format of the texture map may be a tga format.

[0061] Step 103: Obtain material depth information corresponding to each map area, wherein at least two material depth information are different.

[0062] The material depth information is used to indicate the depth value of the material image in the corresponding map area. For example, the material depth information corresponding to one map area is set to 0, and the material depth information corresponding to another map area is set to 0.5.

[0063] In this embodiment, in order to achieve the depth effect, the terminal needs to set different material depth information for the material images of at least two mapping areas in the texture map, so that when forming the depth effect, the material images in the corresponding mapping areas can be offset according to the different material depth information, so that the size of the material image offset is determined by the size of the material depth information, and the parallax offset of the material image visually forms a depth effect.

[0064] Among them, the above-mentioned material depth information can be set by relevant staff for material images in different mapping areas, or the terminal can intelligently identify the image type of the material image belonging to the foreground or background content, so as to generate corresponding material depth information for the material image based on the image type of the identified material image. The specific setting can be made according to needs and is not limited here.

[0065] Step 104 : based on the shooting angle vector of the virtual camera of the target model and the material depth information of each mapping area, render the material image of each mapping area on the target model.

[0066] The shooting angle vector is used to indicate the shooting angle of the virtual camera that shoots the target model. The shooting angle vector may be a vector in the tangent space of the model surface.

[0067] In this embodiment, the image positions of the material images of the mapping areas at different depths under the shooting perspective vector can be clearly determined through the shooting perspective vector of the virtual camera and the material depth information corresponding to each mapping area. The material images of each mapping area are rendered on the target model through the image positions of the material images at different depths, so as to cause each material image to form a visual depth effect. Therefore, the depth effect can be obtained by rendering only one target model, thereby reducing resource loss.

[0068] It should be noted that by introducing the shooting perspective vector, corresponding images can be presented when facing different perspectives, that is, different effects can be seen by rotating different perspectives.

[0069] It can be understood that when the above-mentioned target model is a mask model that needs to render the depth effect of the starry sky, the model rendering method provided in this embodiment can show the real sense of depth of the starry sky on the mask model, improve the performance of the starry sky parallax effect, and will not consume too much performance, thereby maintaining the smoothness of users using the mask model.

[0070] For example, Figure 5 As shown, when setting the current need to render the starry sky depth effect on the target model, Figure 5 The rendered target model shown in FIG. 1 shows a picture corresponding to the starry sky depth effect, and in Figure 5 The image shows the starry sky depth effect corresponding to three different shooting perspective vectors.

[0071] In some embodiments, the shooting perspective vector of the virtual camera based on the target model and the material depth information of each mapping area renders the material image of each mapping area on the target model, which may include: the terminal may determine the position offset information of the material image of each mapping area based on the shooting perspective vector and the material depth information of each mapping area, and then the terminal may determine the image position of each material image on the target model based on the position offset information of each material image, and finally, the terminal may render each material image on the target model based on the image position of each material image, so that the material images of each layer can be partially overlapped to form a spatial front-to-back relationship, that is, having a front-to-back change, such as Figure 5 The material images of different map areas in the image overlap.

[0072] The above-mentioned position offset information is the information that the material image needs to be offset at the corresponding depth, such as the offset direction, offset distance or offset position coordinates, etc., which can be set according to needs and is not limited here.

[0073] Specifically, the position offset information may be obtained based on the product of the shooting viewing angle vector and the material depth information.

[0074] It should be noted that the terminal calculates the position offset information of each material image at the corresponding depth, and can offset each material image to promote a specific arrangement position between the material images to visually form a depth effect. Then, based on the image position of the material image that can visually form a depth effect, each material image is rendered to the corresponding position of the target model to make the target model visually form a depth effect.

[0075] It should be noted that for the starry sky depth effect, when the player moves, the position of distant stars in the field of vision changes less due to their distance, while the position of nearby stars in the field of vision changes more due to their distance. The starry sky depth effect is generated based on the parallax effect, that is, when observing the same object from different perspectives, the position of the object in the field of vision will change due to the change in the observation angle, and the offset distances of stars at different distances are different, so as to form a better depth effect.

[0076] In some embodiments, different map areas are in layers of different levels on the above-mentioned texture map. Therefore, corresponding parameters can be set for material images of different layers, such as the material depth information mentioned above and the material rendering parameters to be mentioned later. Therefore, before obtaining the material depth information corresponding to each map area, it is necessary to configure corresponding levels for different map areas in the texture map.

[0077] Specifically, the terminal can input the texture map into the shader and input the number of rows and columns corresponding to the texture map to be divided. Then, the shader can set corresponding levels for different map areas in the texture map based on the number of rows and columns. The shader can set corresponding levels for different map areas in sequence according to a preset order, such as Figure 6 As shown, from left to right and from top to bottom, the four mapping areas are set to the first level, the second level, the third level and the fourth level respectively. The first level corresponds to Figure 6 The second level corresponds to the map area marked as 1 in Figure 6 The third level corresponds to the map area marked as 2. Figure 6 The fourth level corresponds to the map area marked as 3 in Figure 6 The map area marked as 4 in the figure.

[0078] Furthermore, the above-mentioned rendering of the material image of each mapping area on the above-mentioned target model based on the shooting perspective vector of the virtual camera of the above-mentioned target model and the above-mentioned material depth information of each mapping area may include steps 1041 to 1043:

[0079] Step 1041: Based on the shooting perspective vector and the material depth information of each mapping area, the material image corresponding to the layer where each mapping area is located is processed.

[0080] In this embodiment, the processing of the material images corresponding to the layers in which the mapping areas are located may be to offset the material images in each layer to promote specific arrangement positions between the offset material images to visually form a depth effect.

[0081] Specifically, the processing of the corresponding material images in the layer where each mapping area is located based on the shooting perspective vector and the material depth information of each mapping area may include: the terminal may determine the offset position of the material image of each mapping area based on the shooting perspective vector and the material depth information of each mapping area, and then the terminal may update the material image of each mapping area in the corresponding layer based on the offset position of the material image of each mapping area, so as to enable the material images of each layer to partially overlap and form a spatial front-to-back relationship, that is, to have a front-to-back change, such as Figure 5 The material images of different map areas in the image overlap.

[0082] Among them, the above-mentioned can determine the position of the material image of each mapping area after the offset based on the above-mentioned shooting perspective vector and the above-mentioned material depth information of each mapping area, and can include: the terminal can determine the position offset information of the material image of each mapping area based on the above-mentioned shooting perspective vector and the above-mentioned material depth information of each mapping area, and then, the terminal can determine the position of each material image after the offset based on the position offset information of each material image.

[0083] The position after the shift may be consistent with the image position, or there may be a corresponding mapping relationship between the position after the shift and the image position.

[0084] Specifically, the terminal may directly use the position offset information as the offset position, or the terminal may determine the offset position based on the initial position of the material image and the position offset information, etc. The specific setting may be made according to the requirements and is not limited here.

[0085] For example, the terminal may calculate the difference between the initial position and the position offset information, and use the difference as the position after the offset.

[0086] Step 1042: Mix the processed material images in each layer to obtain a target texture map.

[0087] In this embodiment, when the processed material images of each layer, that is, the offset materials are mixed together to enable the material images of each layer to partially overlap and form a spatial front-to-back relationship, in order to avoid the non-material image area in the layer from blocking the material image area of ​​other layers, the terminal needs to mix the processed material images in each layer to obtain the target texture map.

[0088] Specifically, the transparency channel of the above-mentioned texture map stores transparency information of each map area, and the above-mentioned transparency information is used to indicate the non-transparent material image area and the transparent non-material image area in the map area. The above-mentioned material images after processing in each layer are mixed to obtain the target texture map, including: the terminal can mix the processed material images in the material image areas of each layer based on the above-mentioned transparency information to obtain the target texture map, thereby setting the non-material image area to be transparent to avoid the non-material image area from obstructing the material image areas of other layers.

[0089] For example, Figure 7 As shown, Figure 7 The transparency information in the transparency channel of the texture map is shown, which is controlled by the transparency information. Figure 7 The black area in the image is the transparent non-material image area, and the white area is the non-transparent material image area.

[0090] like Figure 8 As shown, if based on Figure 7 The texture map with transparency information shown in the figure is mixed with material images of different layers, and the target texture map can be obtained. Figure 8 The image shown is a screen where the material images of the two layers are superimposed.

[0091] like Fig. 9 As shown, if not based on Figure 7 Instead of directly mixing the material images of different layers, the target texture map contains Fig. 9 The picture shown blocks the material image area of ​​other layers, that is, the starry sky behind the aircraft cannot be seen in the picture.

[0092] Step 1043: Based on the target texture map, render the material image of each mapping area on the target model.

[0093] In this embodiment, after obtaining the target texture map obtained by mixing the material images of different layers, the terminal can render the material images of each mapping area on the target model based on the target texture map.

[0094] In some embodiments, although material images of different layers are mixed together based only on the shooting perspective vector and material depth information, the mixed effect may not meet user expectations. Therefore, the terminal can further adjust the material image of the corresponding layer in the target texture map so that the adjusted material image can better meet user expectations.

[0095] Specifically, the above-mentioned rendering of the material image of each mapping area on the above-mentioned target model based on the above-mentioned target texture map may include: the terminal may obtain the material rendering parameters for the above-mentioned target model, and then the terminal may render the material image of each mapping area on the above-mentioned target model based on the above-mentioned material rendering parameters and the above-mentioned target texture map.

[0096] Among them, the above-mentioned material rendering parameters include but are not limited to image adjustment parameters for a single layer, layer rendering indication parameters for multiple layers, etc., which can be set according to specific needs and are not limited here.

[0097] The above-mentioned image adjustment parameters include but are not limited to image repetition parameters, image zoom factor, depth indication parameters, brightness parameters and image position parameters, etc., which can be set according to needs and are not limited here.

[0098] Specifically, the above-mentioned image adjustment parameters can be parameters input in real time by the user based on the generated target texture map, that is, the terminal can provide a preview window of the target texture map, and a parameter input control displayed simultaneously with the preview window, so that the user can input the corresponding image adjustment parameters based on the target texture map in the preview window to individually control the size, proportion, position, etc. of a certain material map.

[0099] It should be noted that the above-mentioned depth indication parameter can be the same parameter as the above-mentioned material depth information, that is, both can participate in the offset determination of the material image. The above-mentioned depth indication parameter can also be a different parameter from the above-mentioned material depth information, that is, used to control different processing of the material image. The specific setting can be based on demand and is not limited here.

[0100] It can be understood that the above-mentioned image adjustment parameter settings are actually settings and adjustments for the materials in each layer. For example, when the above-mentioned depth indication parameter can be the same parameter as the above-mentioned material depth information, by setting the depth indication parameter, the distance of each layer can be adjusted to achieve the desired final effect requirements under the viewing angle vector by adjusting the depth, and the distance of each layer can be adjusted more freely.

[0101] In some embodiments, the above-mentioned material rendering parameters may include layer rendering indication parameters, and the above-mentioned layer rendering indication parameters are used to indicate the layer to be rendered in the above-mentioned target texture map. The above-mentioned rendering of the material image of each mapping area on the above-mentioned target model based on the above-mentioned material rendering parameters and the above-mentioned target texture map may include: the terminal may render the material image of the corresponding layer in the above-mentioned target texture map onto the above-mentioned target model based on the above-mentioned layer rendering indication parameters.

[0102] Specifically, the above-mentioned layer rendering indication parameters may include the number of layers and / or layer levels. The above-mentioned number of layers is used to indicate the number of layers to be rendered in the above-mentioned target texture map. If there is only the number of layers, the layers need to be rendered in hierarchical order.

[0103] In some embodiments, the above-mentioned material rendering parameters include image adjustment parameters of the material image of at least one layer, and the above-mentioned rendering of the material image of each mapping area on the above-mentioned target model based on the above-mentioned material rendering parameters and the above-mentioned target texture map may include: the terminal may adjust the material image of the corresponding layer in the above-mentioned target texture map based on the image adjustment parameters of the material image of at least one layer to obtain the adjusted target texture map, and then the terminal may render the material image of each mapping area on the above-mentioned target model based on the above-mentioned adjusted target texture map.

[0104] Specifically, the above-mentioned image adjustment parameters include image repetition parameters, and the above-mentioned image repetition parameters are used to indicate the material repetition situation. The above-mentioned image adjustment parameters based on the material image of at least one layer adjust the material image of the corresponding layer in the above-mentioned target texture map to obtain the adjusted target texture map, which may include: the terminal can repeatedly set the above-mentioned material image in the corresponding layer of the above-mentioned target texture map based on the image repetition parameters of the material image of at least one layer to obtain the adjusted target texture map.

[0105] The above-mentioned material repetition situation includes the material repetition quantity and / or the material repetition position.

[0106] Specifically, the terminal can set the image repetition parameter to 0 to indicate that the material image of a layer is not repeated, and set the image repetition parameter to 1 to indicate that the material image of a layer is repeated a preset number and is repeated at a preset material repetition position in the layer.

[0107] For example, Fig.10 As shown, Fig.10 The left area is a non-repeating material image. Fig.10 The right area shows the material images repeated in the layer in the form of a nine-grid.

[0108] In some embodiments, the above-mentioned image adjustment parameters include an image zoom factor. The above-mentioned image adjustment parameters based on the material image of at least one layer adjust the material image of the corresponding layer in the above-mentioned target texture map to obtain the adjusted target texture map, which may include: the terminal can scale the material image of the corresponding layer in the above-mentioned target texture map based on the image zoom factor of the material image of at least one layer.

[0109] For example, Fig.11 and Fig.12 As shown, the terminal can Fig.11 The material image "aircraft" shown is reduced by the corresponding image zoom factor to obtain Fig.12 A reduced schematic diagram of the "aircraft" is shown.

[0110] In some embodiments, the above-mentioned image adjustment parameters include depth indication parameters. The above-mentioned image adjustment parameters based on the material image of at least one layer adjust the material image of the corresponding layer in the above-mentioned target texture map to obtain the adjusted target texture map, which may include: the terminal can determine the image brightness of the material image of the above-mentioned at least one layer based on the depth indication parameters of the material image of the above-mentioned at least one layer, and then the terminal can perform brightness processing on the material image of the corresponding layer in the above-mentioned target texture map based on the image brightness of the material image of the above-mentioned at least one layer.

[0111] It should be noted that the larger the parallax depth value, the farther the material is visually, and the smaller the change in viewing angle movement. On the contrary, the smaller the parallax depth value, the closer the material is visually, and the larger the change in viewing angle movement. In this regard, the terminal can adjust the brightness of the material image. The larger the parallax depth, the smaller the brightness of the material image, so as to visually present the material as being farther away, thereby achieving a better parallax effect.
