[0028] Embodiments of the present application provide a model rendering method, device, electronic device, and computer-readable storage medium.
[0029] 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.

[0030] 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.
[0031] 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.
[0032] 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 may be performed in an order different from that shown in the accompanying drawings.
[0033] The model rendering method of this embodiment obtains attribute information of a first model, wherein the first model is composed of model planes corresponding to multiple second models, and the attribute information includes position information of each of the model planes in the first model; based on the position information of each of the model planes, each of the model planes is converted into a camera space, and each of the model planes is made to face the virtual camera in the camera space, so as to obtain first pose information of each of the model planes in the camera space; based on the first pose information of each of the model planes, each of the model planes is converted into a world space, so as to obtain second pose information of each of the model planes in the world space; based on the second pose information of each of the model planes and the rendering map corresponding to the second model, each of the model planes in the first model is rendered, so as to improve the rendering effect when rendering multiple models.
[0034] 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:
[0035] Step 101: Acquire attribute information of a first model, wherein the first model is composed of a plurality of model planes corresponding to the second models, and the attribute information includes position information of each of the model planes in the first model.
[0036] Among them, the above-mentioned second model is the model to be rendered. In some scenes, multiple second models need to be rendered at the same time. For example, in scenes such as pearl bracelets and clothing inlaid with pearls, a large number of pearl effects need to be produced, so more second models are needed to express a large number of spherical elements in the scene.
[0037] It is understandable that since the model requires a high number of model vertices when representing spherical elements, in order to improve efficiency, the terminal can use a model plane to replace the second model for rendering to avoid rendering based on model vertices. The model plane can be a face of a specific shape or a billboard plane, etc., which can be set according to needs and is not limited here.
[0038] Among them, the terminal can use the billboard technology to simulate the visual effect of a three-dimensional object using a two-dimensional texture. The BillBoard technology uses a quadrilateral with a texture, and its texture image is the image of the model targeted by the BillBoard technology, that is, a rectangle with the image of the object is used to replace the graphic image of the object. The terminal places the billboard plane corresponding to the BillBoard technology at the center of the position of the second model replaced, and changes with the movement of the camera, always facing the camera.
[0039] It is understandable that, since multiple models to be rendered are merged into one during real-time rendering, only the merged model can be transformed as a whole, and the single model cannot be kept in its respective position for posture transformation. Therefore, in this embodiment, the terminal can record the position information of the model planes corresponding to each second model in the first model, so as to control each model plane to perform independent transformation through the position information of each model plane in the first model, thereby associating all the information required for rendering the second model through a single first model, and also ensuring that each second model can perform corresponding transformation separately. Among them, the position information can be the relative position information of the model plane in the first model, or it can be the position coordinates of the model plane in the first model (such as dividing the coordinate axis with the center of the first model as the origin, and the position coordinates are the position of the center point of the model plane on the coordinate axis), which can be set according to the needs and is not limited here.
[0040] It should be noted that the above-mentioned first model is equivalent to a large model plane, and this large model plane contains multiple model planes of the second model.
[0041] In some embodiments, the above-mentioned position information includes relative position information. Before obtaining the attribute information of the first model, it is necessary to obtain multiple second models to be rendered, so as to construct the first model based on the second models, and determine the attribute information of the first model, that is, determine the relative position information of each model plane in the first model, so that by recording the relative position information, various model sizes can be matched to ensure sufficient relative accuracy.
[0042] First, the terminal may obtain multiple second models to be rendered, and respectively create model planes corresponding to the second models.
[0043] Among them, the above-mentioned multiple second models to be rendered can be a combination of multiple objects of the same type or style in the virtual scene, or a combination of objects that are related and need to appear at the same time in the virtual scene, etc., which can be set specifically according to needs and are not limited here.
[0044] Specifically, the above-mentioned creation of model planes corresponding to each of the above-mentioned second models may include: the terminal may obtain the model size and model position of each of the above-mentioned second models, and then, at the model position of each of the above-mentioned second models, create model planes matching the model size of each of the above-mentioned second models.
[0045] The normal lines of the above-mentioned model planes are in the same direction, for example, the normal lines are facing upwards.
[0046] It can be understood that since both the second model and the model plane occupy a certain space, in order to match the two, they can be established based on the center points of the second model and the model plane, that is, the model position of the second model is the position of the center point of the second model, and a bounding box can be constructed around the second model, and the center point of the bounding box is set as the center point of the second model.
[0047] Furthermore, since the model plane is a two-dimensional plane, the length and width of the model plane can be aligned with the X-axis and Y-axis in the space where the second model is located, and the length and width of the model plane can be set based on the size of the second model or the bounding box built around the second model. For example, when the second model is a pearl model, the length and width of the model plane of the second model are set according to the radius size of the enclosing sphere of the pearl model. For example, the length and width of the model plane are both the product of 2 and the radius size, that is, the diameter of the enclosing sphere.
[0048] For example, Figure 2 and Figure 3 As shown, in Figure 2 The figure shows a series of independent spherical models, which are the second models. Then, the terminal creates a model plane for each second model to obtain Figure 3 The model planes corresponding to the second models shown are Figure 3 It contains multiple independent four-sided planes.
[0049] Secondly, the terminal can construct the first model based on the model plane corresponding to each of the above second models, that is, Figure 3 The model planes corresponding to the second models in are merged into a single model, namely the first model.
[0050] Specifically, the terminal may use 3dmax software and the attach command to merge the model planes corresponding to the second models into the first model.
[0051] Finally, the terminal may obtain the center position of the first model, that is, the position of the center point of the first model, and respectively determine the relative position information between each of the model planes and the center position of the first model.
[0052] The center position of the first model may be the center position of the first model itself or the center position of the bounding box of the first model. The center position may be set according to the requirements and is not limited here.
[0053] It can be understood that after the terminal obtains the center position of the first model, it is necessary to calculate the relative position information between each model plane and the center position of the first model based on the center position of the first model. The relative position information can be the relative distance between each model plane and the center position of the first model on different coordinate axes, relative distance ratio, etc., or it can be the relative direction between each model plane and the center position of the first model and the relative distance between the two, etc. The specific setting can be based on demand and is not limited here.
[0054] The position of the model plane compared with the center position of the first model may be the center point position of the model plane or the position of any point on the model plane, etc., which may be set according to requirements and is not limited here.
[0055] Specifically, the above-mentioned determination of the relative position information between each of the above-mentioned model planes and the center position of the above-mentioned first model may include: the terminal may respectively determine the position difference information between the center position of each of the above-mentioned model planes and the center position of the above-mentioned first model; then, the terminal may obtain the model size of the above-mentioned first model, and use the ratio of the above-mentioned position difference information to the model size of the above-mentioned first model as the above-mentioned relative position information.
[0056] The model size of the first model may be the model size of the first model itself or the size of the bounding box of the first model, which may be set according to requirements and is not limited here.
[0057] Exemplarily, if the minimum coordinate value of the bounding box of the first model is set to (0, 0, 0) and the maximum coordinate value is set to (1, 1, 1), then the terminal can calculate the position difference between the center position of the model plane and the center position of the above-mentioned first model, and then use the ratio of the position difference to the size of the bounding box of the first model as the above-mentioned relative position information.
[0058] In some embodiments, it also includes: the terminal can convert the relative position information of each of the above-mentioned model planes into color indication information. Then, among the model vertices of the above-mentioned first model, the target model vertices corresponding to each of the above-mentioned model planes are respectively determined, and the color indication information of each of the above-mentioned model planes is respectively written into the vertex attributes of the target model vertices corresponding to each of the above-mentioned model planes, such as writing into the model vertex color. Accordingly, the above-mentioned acquisition of the attribute information of the first model may include: acquiring the color indication information of each of the above-mentioned model planes from the vertex attributes of the model vertices of the above-mentioned first model, so as to determine the relative position information of the corresponding model plane based on the above-mentioned color indication information.
[0059] The color indication information is used to indicate the relative position information of the model plane.
[0060] Among them, the target model vertex corresponding to the model plane can be the model vertex closest to the center position of the model plane, or the model vertex consistent with the center position of the model plane, etc., which can be set according to needs and is not limited here.
[0061] The relative position information of each of the above-mentioned model planes is converted into color indication information, which may be the conversion of three coordinates in the relative position information into RGB color values, for example, multiplying the relative position coordinates by 255 to convert them into RGB color values.
[0062] Further, based on the above example, if the minimum coordinate value of the bounding box of the first model is set to (0, 0, 0) and the maximum coordinate value is set to (1, 1, 1), then the relative position information calculated by the terminal is in the range of -0.5 to 0.5. For the convenience of calculation, before the relative position information of each of the above model planes is converted into color indication information, the relative position information needs to be normalized so that it is mapped in the range of 0 to 1. The relative position information can be normalized to the range of 0 to 1 by calculating the sum between the relative position information and (0.5, 0.5, 0.5).
[0063] It should be noted that after the vertex colors are baked in, that is, the color indication information of each of the above-mentioned model planes is written into the vertex attributes of the target model vertices corresponding to each of the above-mentioned model planes, the RGB color values correspond to the XYZ coordinate values in the relative position information. However, due to the differences in coordinate systems of different software, the channels storing vertex colors need to be adjusted accordingly. Taking 3dmax imported into the neox engine as an example, in order to match the coordinate axes, the values of its g and b channels need to be exchanged, that is, the Y axis and Z axis are opposite in different coordinate systems, so the G color value and the B color value need to be exchanged.
[0064] Step 102: Based on the position information of each of the above model planes, each of the above model planes is converted into the camera space respectively, and each model plane is made to face the virtual camera in the above camera space to obtain the first position information of each of the above model planes in the above camera space.
[0065] In this embodiment, the terminal can convert each model plane into the camera space so that the X-axis and Y-axis of each model plane can face the virtual camera in the camera space, that is, the front of the model plane faces the virtual camera, so that the changes of each model plane can be adjusted in real time in the camera space according to the changes of the virtual camera.
[0066] It should be noted that the center point of each model plane in the camera space is located at the world origin, and the pose of each model plane in the world space needs to be adjusted based on the first pose information obtained.
[0067] The terminal may convert each model plane into the camera space based on its local coordinates, so that different model planes are located at different positions in the camera space.
[0068] Specifically, the terminal can further collect the local coordinates of the center position of the first model and the model size of the first model (the model size can be the size of the first model bounding box) that are preset or automatically injected by the engine, so as to restore the local coordinates of each model plane based on the collected information about the first model and the position information of each model plane, such as the relative position of each model plane in the first model, which can be the local coordinates of the center point of each model plane.
[0069] In some embodiments, the first pose information of each of the above-mentioned model planes in the above-mentioned camera space is obtained, including: obtaining the pose adjustment parameters of each of the above-mentioned model planes in the above-mentioned camera space, the pose adjustment parameters can be generated by the user in real time, or can be pre-set by the user, and the pose adjustment parameters of different model planes can be the same or different. The pose adjustment parameters can include position offset parameters and pose adjustment parameters. For example, the pose adjustment parameters can include scaling parameters, rotation parameters, etc., which are set specifically according to needs and are not limited here.
[0070] Then, the terminal can adjust the posture of each of the above-mentioned model planes in the above-mentioned camera space based on the above-mentioned posture adjustment parameters of each of the above-mentioned model planes, and obtain the first position information of each of the above-mentioned model planes in the above-mentioned camera space, and the first position information is the posture information of the model plane after adjustment in the camera space.
[0071] In some embodiments, since different model planes have different positions in the first model, and the virtual camera has different viewing angles, the model planes at different positions away from the virtual camera need to undergo different degrees of posture changes. Therefore, the above-mentioned acquisition of the posture adjustment parameters of each of the above-mentioned model planes in the above-mentioned camera space may include: the terminal may determine the target viewing angle of the above-mentioned virtual camera during the current shooting, and then, the terminal may determine the posture adjustment parameters of each of the above-mentioned model planes in the above-mentioned camera space under the above-mentioned target viewing angle based on the position information of each of the above-mentioned model planes.
[0072] Step 103: Based on the first pose information of each of the model planes, each of the model planes is converted into the world space to obtain the second pose information of each of the model planes in the world space.
[0073] In this embodiment, the terminal needs to convert each model plane into the world space based on the first pose information of the model plane obtained in the camera space to obtain the second pose information of each model plane in the world space.
[0074] It can be understood that since the center point of each model plane in the camera space is at the origin in the world space, when the terminal converts the model plane from the camera space to the world space, it is necessary to adjust the posture of the model plane based on the first posture information at the origin of the world space to obtain the second posture information of the model plane in the world space.
[0075] Step 104: Render each of the model planes in the first model based on the second pose information of each of the model planes and the rendering map corresponding to the second model.
[0076] In this embodiment, the terminal can obtain the rendering map of the above-mentioned second model. Since each plane model has corresponding second pose information, each model plane in the first model can be rendered based on the second pose information of each plane model and a corresponding rendering map is assigned to each plane model, so as to achieve the rendering effect of each second model in the virtual scene, so that the rendering effect of the model can be achieved by rendering only the model plane, which improves the rendering effect when rendering multiple models and reduces the loss required for rendering.
[0077] The above-mentioned rendering maps include but are not limited to color maps, transparency maps, etc., which can be set according to specific needs and are not limited here.
[0078] For example, Figure 4 As shown, from Figure 4 As can be seen in , if the second model is set as a series of spherical models, the color map used by the model planes of each spherical model in the scene is the same color map, and each model plane corresponds to a color map, and each model plane corresponds to its own UV texture coordinates. The color on the map can be sampled by the UV texture coordinates and pasted to the model plane, and finally rendered as follows Figure 5 Schematic diagram of the rendering effect shown.
[0079] From the above content, it can be seen that by obtaining the attribute information of the first model composed of multiple model planes of the second model, the attribute information includes the position information of each of the above model planes in the above first model. Then, based on the position information of each of the above model planes, each of the above model planes is converted to the camera space respectively, and each model plane is made to face the virtual camera in the above camera space, so as to obtain the first pose information of each of the above model planes in the above camera space. Finally, based on the above first pose information of each of the above model planes, each of the above model planes is converted to the world space respectively, and the second pose information of each of the above model planes in the above world space is obtained, so as to render each of the above model planes in the above first model based on the above second pose information of each of the above model planes and the rendering map corresponding to the above second model, so as to record the position information of each model plane in the first model, so as to determine the pose transformation information of each model plane respectively, so as to render each model plane accordingly, so as to improve the rendering effect when rendering multiple models.
[0080] This embodiment also provides a model rendering device, which can be integrated into a terminal device. Figure 6 As shown, the model rendering device may include:
