[0020] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0021] Figure 1 A process 100 of some embodiments of the model rendering method according to the present disclosure is shown. The model rendering method comprises the following steps: Step 101: Receive a model access address sent by a target user.

[0022] In some embodiments, the execution subject (e.g., server) of the model rendering method may receive a model access address sent by a target user. The target user may be the user who sent the model access address. The model access address may be a network address for accessing the initial three-dimensional model. For example, the model access address may be a URL link.

[0023] Step 102: Load the initial three-dimensional model according to the model access address and the preset model format.

[0024] In some embodiments, the execution subject may load the initial three-dimensional model according to the model access address and the preset model format. The preset model format may be a preset format for loading the initial three-dimensional model. For example, the preset model format may be a GLTF model format. Figure 4 As shown, a model loading test diagram of some embodiments of the model rendering method of the present disclosure is shown. It can be seen that the scene is equipped with multiple real-time light sources, and the light sources can act on multiple components at the same time, making the model texture clearer.

[0025] In practice, the above initial 3D model can be loaded by the following steps: The first step is to asynchronously load the three-dimensional model represented by the above model access address.

[0026] The second step is to add the loaded 3D model to the pre-generated 3D model scene through a preset loading algorithm. In practice, the loaded 3D model can be added to the pre-generated 3D model scene through the GLTFLoader tool. The 3D model scene can be a Three.js scene for displaying the loaded 3D model.

[0027] Step 103, in response to receiving the adjustment information for the initial three-dimensional model sent by the target user, the initial three-dimensional model is adjusted according to the adjustment information to generate a three-dimensional model after adjustment.

[0028] In some embodiments, the execution entity may, in response to receiving adjustment information for the initial three-dimensional model sent by the target user, perform parameter adjustment processing on the initial three-dimensional model according to the adjustment information to generate a three-dimensional model after parameter adjustment.

[0029] In practice, the above initial 3D model can be adjusted by the following steps to generate a 3D model after adjustment: The first step is to receive adjustment information for the initial three-dimensional model sent by the target user, wherein the adjustment information may be information for adjusting the displayed initial three-dimensional model.

[0030] The second step is to split the adjustment information to generate split adjustment information. The split adjustment information may include: size information and material information. The size information may be the size of the required initial three-dimensional model. The material information may be the material of the model to be modified. The material information may include but is not limited to: color and texture.

[0031] The third step is to adjust the size of the three-dimensional model according to the scaling factor included in the size information, wherein the scaling factor may be a factor used to represent the degree of scaling of the initial three-dimensional model.

[0032] The fourth step is to adjust the material of the above three-dimensional model to the three-dimensional model material represented by the above material information to generate a three-dimensional model after parameter adjustment.

[0033] Step 104, mapping and unfolding processing is performed on the adjusted three-dimensional model to generate an unfolded three-dimensional model.

[0034] In some embodiments, the execution entity may perform mapping and expansion processing on the adjusted three-dimensional model to generate an expanded three-dimensional model.

[0035] In practice, the execution subject may perform mapping and expansion processing on the three-dimensional model after parameter adjustment through the following steps to generate an expanded three-dimensional model: The first step is to import the adjusted 3D model into the unfolding module, which may be the bpy module of the Blender suite.

[0036] The second step is to select the above-mentioned adjusted three-dimensional model and adjust the above-mentioned expansion module to the editing mode. In practice, the adjusted three-dimensional model in the above-mentioned expansion module can be switched to the editing mode to facilitate mapping expansion.

[0037] The third step is to map and unfold each face of the three-dimensional model after the above parameter adjustment. The above mapping and unfolding can be UV Unwrapping.

[0038] The fourth step is to adjust the above expansion module to the object mode in response to the completion of the mapping and expansion of each surface of the three-dimensional model after the above parameter adjustment.

[0039] The fifth step is to save the adjusted 3D model after mapping and unfolding to a folder to obtain the unfolded 3D model.

[0040] In the process of adopting technical solutions to solve the above technical problems, the following technical problems often occur: when the UV of the model is unfolded, the secants of the closed three-dimensional model are different, resulting in inconsistency in the unfolded two-dimensional image, which in turn causes distortion of the rendered image.

[0041] In some optional implementations of some embodiments, the execution subject may perform mapping and expansion processing on the three-dimensional model after parameter adjustment through the following steps: In the first step, at least one mesh slit is generated according to the three-dimensional model after parameter adjustment, wherein the mesh slit in the at least one mesh slit is used to cut the mesh included in the three-dimensional model and generate new mesh vertices.

[0042] In the second step, according to the at least one grid cut, the grid included in the three-dimensional model after parameter adjustment is divided into a plurality of grid disk structures to obtain a grid disk structure group.

[0043] The third step is to expand each grid disk structure in the grid disk structure group into a two-dimensional plane according to a preset algorithm, wherein the preset algorithm may be a PCA (Principal Component Analysis) algorithm.

[0044] In the fourth step, for each grid disk structure in the above grid disk structure group, the following determination steps are performed: The first determination step is to determine the surface curvature corresponding to the mesh disk structure. In practice, the surface curvature corresponding to the mesh disk structure can be determined using a curvature calculation formula.

[0045] The second determination step is to segment and unfold the grid disk structure according to the preset algorithm in response to the surface curvature being greater than a preset surface curvature threshold.

[0046] The fifth step is to perform texture coordinate packing processing on each unfolded grid disk structure to generate each packed grid disk structure as the unfolded three-dimensional model.

[0047] The above-mentioned first step to the seventh step, as an inventive point of an embodiment of the present disclosure, combined with the following step "step 106", solves the technical problem "When the UV unfolding of the model is performed, due to the different secants of the closed three-dimensional model, the unfolded two-dimensional image is inconsistent, which in turn causes the rendered image to be distorted". The reasons for the distortion of the rendered image are as follows: When the UV unfolding of the model is performed, due to the different secants of the closed three-dimensional model, the unfolded two-dimensional image is inconsistent, which in turn causes the rendered image to be distorted. If the above factors are solved, the effect of avoiding the distortion of the rendered image can be achieved. In order to achieve this effect, the present disclosure first generates at least one grid cut according to the above-mentioned three-dimensional model after parameter adjustment. Thus, multiple grid cuts can be generated. Second, according to the above-mentioned at least one grid cut, the grid included in the above-mentioned three-dimensional model after parameter adjustment is divided into multiple grid disk structures to obtain a grid disk structure group. Thus, the three-dimensional model can be divided into multiple grid disks by grid cuts. Third, according to a preset algorithm, each grid disk structure in the above-mentioned grid disk structure group is unfolded into a two-dimensional plane. Thus, the divided three-dimensional model can be unfolded on a two-dimensional plane to achieve dimensionality reduction processing of the three-dimensional model. Fourth, for each grid disk structure in the above-mentioned grid disk structure group, the following determination steps are performed: determining the surface curvature corresponding to the above-mentioned grid disk structure; in response to the above-mentioned surface curvature being greater than the preset surface curvature threshold, the above-mentioned grid disk structure is segmented and unfolded according to the above-mentioned preset algorithm. Thus, the grid disk with a higher curvature can be divided again, thereby reducing the curvature and reducing distortion. Thus, the situation where the unfolded two-dimensional image is inconsistent due to different secants can be avoided. Fifth, the texture coordinates of each unfolded grid disk structure are packaged to generate each packaged grid disk structure as the unfolded three-dimensional model. Thus, the unfolded three-dimensional model can be texture packaged. Combined with "step 106", according to the baked three-dimensional model, the baked three-dimensional model is rendered to generate a three-dimensional model rendering. Thus, the distortion of the rendered three-dimensional model rendering can be avoided.

[0048] Step 105 , baking the unfolded three-dimensional model to generate a baked three-dimensional model.

[0049] In some embodiments, the execution entity may bake the unfolded three-dimensional model to generate a baked three-dimensional model.

[0050] In some optional implementations of some embodiments, the execution subject may bake the unfolded three-dimensional model through the following steps to generate a baked three-dimensional model: The first step is to load the unfolded 3D model into a baking module, which may be a bpy module of the Blender suite.

[0051] The second step is to receive the baking configuration information sent by the target terminal, wherein the baking configuration information may include but is not limited to: light source information and baking resolution.

[0052] The third step is to generate a light source component in the baking module according to the light source information included in the baking configuration information.

[0053] Step 4: Create an initial texture file group, wherein the initial texture file may be a texture for storing baked texture information.

[0054] The fifth step is to distribute and process the material information corresponding to the initial texture file group and the expanded three-dimensional model. Here, for each initial texture file in the initial texture file group, the material part of the expanded three-dimensional model corresponding to the initial texture file is determined.

[0055] The sixth step is to obtain baking information, and, based on the baking information, bake the initial map file included in the unfolded three-dimensional model to generate a baked three-dimensional model, so as to bake the baking information into the initial map file.

[0056] Step 7: Save the baked 3D model to a folder.

[0057] Step 106: According to the baked three-dimensional model, rendering processing is performed on the baked three-dimensional model to generate a three-dimensional model rendering.

[0058] In some embodiments, the execution entity may perform a rendering process on the baked three-dimensional model according to the baked three-dimensional model to generate a three-dimensional model rendering.

[0059] In practice, the execution subject may perform rendering processing on the baked 3D model through the following steps: In the first step, the baked three-dimensional model is replaced by the initial three-dimensional model.

[0060] The second step is to obtain the pre-stored model adjustment information, and adjust the baked 3D model according to the pre-stored model adjustment information to generate an adjusted 3D model. The pre-stored model adjustment information may be a pre-stored JSON file for adjusting the baked 3D model.

[0061] The third step is to input the above adjustments into a preset renderer to perform a rendering loop on the above adjusted 3D model to obtain a rendered 3D model. In practice, first, the above baked 3D model can be input into a pre-configured renderer. Secondly, a camera and a light source can be set in the renderer to ensure the correct display of the model. Then, the above adjusted 3D model can be subjected to a rendering loop for real-time rendering.

[0062] The fourth step is to generate a 3D model rendering according to the rendered 3D model. Here, each rendering layer in the rendered 3D model can be combined to generate a 3D model rendering.

[0063] In the process of adopting technical solutions to solve the above technical problems, the following technical problems are often accompanied: when the three-dimensional model is rendered as a whole, the model rendering speed is slow and the rendering efficiency is low, so it takes a long time to render the model.

[0064] In some optional implementations of some embodiments, the execution subject may perform rendering processing on the baked three-dimensional model to generate a three-dimensional model rendering through the following steps: In the first step, the baked three-dimensional model is divided into blocks to generate a group of divided models.

[0065] The second step is to determine the baked three-dimensional model as a root node, and generate a quadtree model based on the root node.

[0066] The third step is to match each of the block models in the block model group with each of the nodes included in the quadtree model to obtain a matched quadtree.

[0067] Step 4: For each node in the quadtree after the above matching, perform the following processing steps: The first processing step is to determine whether the node intersects with the baked three-dimensional model.

[0068] The second processing step is to determine the node and the child node corresponding to the node as a first rendering node in response to the node not intersecting with the baked three-dimensional model.

[0069] The third processing step is to determine, in response to the node intersecting with the baked three-dimensional model, whether each child node corresponding to the node intersects with the baked three-dimensional model.

[0070] In a fourth processing step, the node and the sub-nodes intersecting with the baked three-dimensional model among the sub-nodes corresponding to the node are determined as second rendering nodes.

[0071] In the fifth step, the CPU performs multi-dimensional matrix processing on the divided models corresponding to the determined second rendering nodes in real time, and performs smoothing processing on the vertices corresponding to each divided model.

[0072] In the sixth step, each smoothed block model is transmitted to the shader according to the position of the corresponding node in the quadtree model for rendering to obtain a three-dimensional model rendering.

[0073] The above-mentioned first step to the seventh step, as an inventive point of an embodiment of the present disclosure, solves the technical problem of "when the three-dimensional model is rendered as a whole, the model rendering speed is slow, the rendering efficiency is low, and it takes a long time to render the model". The reasons why it takes a long time to render the model are as follows: when the three-dimensional model is rendered as a whole, the model rendering speed is slow, the rendering efficiency is low, and it takes a long time to render the model. If the above factors are solved, the effect of reducing the time for rendering the model can be achieved. In order to achieve this effect, the present disclosure first blocks the above-mentioned baked three-dimensional model to generate a block model group. Thus, the three-dimensional model can be divided into different data blocks. Second, the above-mentioned baked three-dimensional model is determined as a root node, and a quadtree model is generated according to the above-mentioned root node. Thus, a quadtree structure can be obtained. Third, each block model in the above-mentioned block model group is matched with each node included in the above-mentioned quadtree model to obtain a matched quadtree. Thus, each data block can be combined with a node in the quadtree. Fourth, for each node in the above-mentioned matched quadtree, the following processing steps are performed: determine whether the above-mentioned node intersects with the above-mentioned baked three-dimensional model; in response to the node not intersecting with the above-mentioned baked three-dimensional model, determine the above-mentioned node and the child node corresponding to the above-mentioned node as the first rendering node; in response to the above-mentioned node intersecting with the above-mentioned baked three-dimensional model, determine whether each child node corresponding to the above-mentioned node intersects with the above-mentioned baked three-dimensional model; determine the child node and the above-mentioned node that intersect with the above-mentioned baked three-dimensional model in each child node corresponding to the above-mentioned node as the second rendering node. Thus, it can be determined whether each data block needs to be rendered by traversal, and the data blocks are classified according to the traversal results. Fifth, the multi-dimensional matrix processing is performed on the block models corresponding to each second rendering node determined by the CPU in real time, and the vertices corresponding to each block model are smoothed; the smoothed block models are transmitted to the shader according to the position of the corresponding node in the quadtree model for rendering, and a three-dimensional model effect diagram is obtained. Thus, the rendering of the three-dimensional model is completed. By dividing the three-dimensional model into blocks and rendering only the data blocks that need to be rendered, the transmission of rendering data is reduced, thereby improving the rendering efficiency and reducing the time for rendering the three-dimensional model.

[0074] Step 107: receiving an export request sent by a target user, and determining a target export format according to the export request.

[0075] In some embodiments, the execution host may receive an export request sent by a target user, and determine a target export format according to the export request. The export request may be a request for exporting the three-dimensional model rendering. In practice, format information representing the format of the three-dimensional model rendering selected by the target user may be selected from the export request to determine the target export format.

[0076] Step 108, generating a three-dimensional model rendering corresponding to the target export format, and exporting the three-dimensional model rendering.

[0077] In some embodiments, the execution subject may generate a 3D model rendering corresponding to the target export format, and export the 3D model rendering. In practice, the format of the 3D model rendering may be converted to the target export format, and the converted 3D model rendering may be exported.

[0078] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the model rendering method of some embodiments of the present disclosure, the situation where the effect of the rendered three-dimensional model is poor or even the three-dimensional model cannot be rendered is avoided. Specifically, the reason for the poor effect of the rendered three-dimensional model or even the inability to render the three-dimensional model is that the uploaded three-dimensional model information may be incomplete, resulting in the poor effect of the rendered three-dimensional model or even the inability to render the three-dimensional model. Based on this, the model rendering method of some embodiments of the present disclosure first receives the model access address sent by the target user. Thus, the storage address of the initial three-dimensional model can be determined. Secondly, the initial three-dimensional model is loaded according to the above-mentioned model access address and the preset model format. Thus, the initial three-dimensional model can be loaded according to the preset format. Then, in response to receiving the adjustment information for the above-mentioned initial three-dimensional model sent by the above-mentioned target user, the above-mentioned initial three-dimensional model is adjusted according to the above-mentioned adjustment information to generate a three-dimensional model after parameter adjustment. Thus, various parameters of the initial three-dimensional model can be adjusted. Afterwards, the above-mentioned three-dimensional model after parameter adjustment is mapped and expanded to generate an expanded three-dimensional model; and the above-mentioned expanded three-dimensional model is baked to generate a baked three-dimensional model. Thus, by automatically mapping the expansion and baking, it is ensured that the model can be automatically expanded and baked when the three-dimensional model information is missing, and complete data support is provided for subsequent rendering and output. Then, according to the above-mentioned three-dimensional model after baking, the above-mentioned three-dimensional model after baking is subjected to rendering of the rendering to generate a three-dimensional model rendering. Thus, the rendering of the rendering of the three-dimensional model after rendering is completed, and it is ensured that the model can be automatically expanded and baked when the three-dimensional model information is missing, and complete data support is provided for subsequent rendering and output. Finally, the export request sent by the above-mentioned target user is received, and the target export format is determined according to the above-mentioned export request; a three-dimensional model rendering corresponding to the above-mentioned target export format is generated, and the above-mentioned three-dimensional model rendering is exported. Thus, the rendered rendering can be exported in the format required by the user. It avoids the situation where the effect of the rendered three-dimensional model is poor or even the three-dimensional model cannot be rendered.
