Description

Technical Field

[0001] The present application relates to the technical field of packaging design, and in particular to a 3D rendering design method, device and electronic equipment for cigarette packaging. Background Art

[0002] The characteristics of cigarette packaging design are that the product shape geometry is standardized and the outer packaging changes frequently. This requires packaging design work to make different graphic designs for products of the same specifications. Most cigarette packaging design work is based on traditional 2D graphic design software, and typical 2D graphic software is Adobe illustrator. Given that 3D rendering simulation has more expressive advantages than 2D plane drawings, it is often necessary to convert 2D design results into 3D rendering simulation in packaging design work. In the current existing methods, graphic designers complete the graphic design in 2D layer design software, and then input 2D pictures as a reference for modeling. The 3D modeling and rendering process is completed by 3D modeling and rendering software. Typical 3D software is Autodesk 3DMax, Maya, etc.

[0003] It can be seen that the current method must use commercial 3D software to manually complete modeling and rendering adjustments, which objectively increases the software skill requirements for designers. The results of graphic design cannot be directly used in the 3D rendering process, resulting in a waste of time and cost. In addition, since the generated 3D model rendering is based on desktop software such as 3DMax, it cannot be separated from the software and can only be used locally, which is inconvenient to use, especially in the case of collaborative design, communication is difficult.

[0042] See also Figure 1, Figure 1 : is a flow chart of a 3D rendering design method for a cigarette package provided in an embodiment of the present application. In the embodiment of the present application, the method comprises:

[0043] S101, acquiring historical graphic design data in a historical database, splitting each of the historical graphic design data into different data sets according to layers, and generating each 3D texture data based on each of the data sets.

[0044] The execution entity of this application can be a cloud server.

[0045] In the embodiment of the present application, historical graphic design data will be stored in the historical database, and the cloud server will split the historical graphic design data based on the layer to obtain multiple data sets, and then generate different 3D texture data based on these data sets. The generated 3D texture data can correspond to each layer in the historical graphic design data, so as to facilitate subsequent direct call.

[0046] In one possible implementation, the splitting of each of the historical graphic design data into different data sets by layer includes:

[0047] Parsing and splitting each of the historical graphic design data to obtain a plurality of layer data;

[0048] The layer information corresponding to each layer data is saved as a data set to obtain different data sets, wherein the layer information includes name, path, object, and graphic data.

[0049] In the embodiment of the present application, the historical graphic design data will be divided into a plurality of layer data, each layer data contains layer information such as name, path, object, graphic data, etc. The cloud server will integrate and save the plurality of layer information corresponding to each layer data to generate a data set, so that each data set finally obtained can correspond to a related data set of the layer data.

[0050] In one possible implementation, the generating each 3D texture data based on each data set includes:

[0051] Convert each layer information in each data set into a plurality of texture data, so that different texture data correspond to different material properties;

[0052] The texture data in each of the data sets are merged respectively to obtain 3D texture data corresponding to each of the data sets.

[0053] In an embodiment of the present application, layer information is converted into texture data corresponding to different material properties according to specific information categories. By merging the various texture data in a data set, the data set, that is, the 3D texture data corresponding to the layer, can be finally generated.

[0054] S102: Receive first plane design data sent by a first terminal, and select basic polygon mesh data of a category corresponding to the first plane design data.

[0055] In the embodiment of the present application, when the user wants to generate a corresponding 3D rendering model on the first terminal, the user will send the first plane design data designed by the user, that is, the first plane design data to be 3D rendered, to the cloud server through the first terminal. After receiving the first plane design data, the cloud server will select the corresponding basic polygon network data, that is, the basic cigarette box geometry data framework, according to the specific cigarette box category designed in the first plane design data.

[0056] S103, generating a mosaic image from each target 3D texture data corresponding to the first graphic design data, generating a rendering data packet based on the mosaic image and the basic polygonal mesh data, and sending the rendering data packet to the first terminal so that the rendering data is rendered in the first terminal.

[0057] In the embodiment of the present application, according to the specific layers of the first plane design data, the cloud server will select the target 3D texture data corresponding to each layer, and use this to generate a mosaic of each target 3D texture data. Then the cloud server will package the mosaic and the basic polygon network data into a rendering data packet and send it to the first terminal. After receiving the rendering data packet, the first terminal can complete the 3D rendering process on the spot according to the rendering data packet on the first terminal.

[0058] In one embodiment, the method further comprises:

[0059] Receive annotation information, determine a target rendering data packet of the annotation information, and construct a first mapping relationship between the annotation information and the target rendering data packet;

[0060] When first display request information sent by the second terminal is received, the annotation information is displayed to the second terminal based on the first mapping relationship.

[0061] In the embodiment of the present application, when a user annotates a 3D rendering model, annotation information will be generated and sent back to the cloud server. The cloud server will construct a first mapping relationship between the annotation information and its corresponding target rendering data packet, so that when the first display request information sent by other terminals is subsequently received, that is, when other terminals want to view the annotations, the annotation information will be displayed according to the first mapping relationship, so that different terminals can communicate and exchange annotations based on the same model design, thereby realizing the remote collaborative design process.

[0062] In one embodiment, the method further comprises:

[0063] storing the first graphic design data as the historical graphic design data;

[0064] When receiving the second graphic design data sent by the first terminal, searching each of the historical graphic design data for matching graphic design data having a continuous matching ratio with the second graphic design data higher than a preset ratio;

[0065] The matching plane design data with the highest continuous matching ratio is used as target matching plane design data, a rendering auxiliary data packet is generated based on matching data between the target matching plane design data and the second plane design data, and the rendering data packet is generated based on non-matching data of the second plane design data.

[0066] In the embodiment of the present application, the first graphic design data newly uploaded by the user will also be stored as historical graphic design data. When the user uploads the second graphic design data through the first terminal, that is, uploads the new design data, the cloud server will first determine the matching graphic design data with strong similarity to the graphic design data uploaded this time by querying the historical graphic design data. Since the design data can be understood as consisting of multiple layers, and each layer can be understood as corresponding to a printing process, when there is a continuous match, it means that there are several consecutive printing processes that are the same. For this part, the part of the rendering data required to finally generate the 3D rendering model can be extracted from the historical data without repeating the calculation process. Therefore, the cloud server will first determine the target matching graphic design data with the highest continuous matching ratio as the closest data, and directly generate a rendering auxiliary data packet from the historical database based on the matching data that matches it with the second graphic design data. Then, the cloud server will complete the calculation and generation process of the rendering data packet based on the non-matching data different from the target matching graphic design data, thereby improving the processing efficiency and reducing the occupation of processing resources.

[0067] In one embodiment, the method further comprises:

[0068] Parameter adjustment information of each matching plane design data relative to the second plane design data is obtained, auxiliary information is generated based on each parameter adjustment information, and the auxiliary information is displayed to the first terminal.

[0069] In the embodiment of the present application, after the superposition of different printing process steps, the color and other parameters of the packaging box may change, that is, the actual production effect under the superposition of multiple printing processes may deviate from the theoretically calculated effect. Therefore, when making a new design, it may be necessary to adjust the design parameters to ensure that the final 3D rendering effect is close to the actual effect. Therefore, the cloud server will also calculate what kind of parameter adjustment has been made to each matching graphic design data relative to the second graphic design data based on the matching graphic design data that has some steps that are the same or similar to the second graphic design data, obtain parameter adjustment information, and integrate each parameter adjustment information into auxiliary information. This allows users to assist their judgment based on the auxiliary information displayed in the first terminal, thereby improving the efficiency of their parameter adjustment.

[0070] In one embodiment, the method further comprises:

[0071] receiving the communication request information sent by the first terminal, and determining a target terminal corresponding to the communication request information;

[0072] A temporary session window is established between the first terminal and the target terminal.

[0073] In an embodiment of the present application, if a user wishes to communicate with the designer of a certain matching graphic design data, the cloud server will receive the communication request information, determine the target terminal where the designer is located, and finally build a temporary session window to facilitate temporary communication between the two.
