[0001] This application relates to the field of image processing technology, specifically to a method and apparatus for changing the model material of a design drawing. Background Technology
[0002] With the development of the software industry, the creation of drawings is often controlled by software, including the generation of design drawings. A common issue in design drawings is the need to change the materials of the model, such as replacing plain tiles with patterned tiles. In related technologies, when the model's material needs to be changed, the model and its associated materials are typically obtained. Then, lighting, diffuse reflection calculations, and other methods are used to render the model after the material change, resulting in an image of the model with the changed material. However, this method requires a large amount of computation on the GPU, leading to significant computational overhead and high resource consumption when changing the material of a model in the design drawing.

[0027] Multiply the light color by the diffuse color to obtain the first color value;
[0028] The first color value is superimposed with the reflected and refracted color to obtain the second color value;
[0029] The target model is colored according to the second color value and the target material texture to obtain the model image of the target model in the design drawing.

[0043] After receiving a material selection instruction, the target model is determined from each model in the design drawing. Based on the material selection instruction, the corresponding target material texture is determined from each material texture map of the target model. The target material texture is then merged with the lighting map, diffuse map, and reflection and refraction map of the design drawing to obtain the model image of the target model in the design drawing. Thus, after generating the design drawing with only one rendering, when changing the material of any model in the design drawing, the layers of the design drawing and the material texture of the model can be directly merged to obtain the model image of the model with the changed material. There is no need to re-perform lighting, diffuse, and reflection and refraction calculations when changing the model's material, thereby reducing the amount of calculation required when changing the model's material in the design drawing and reducing the resources required when changing the model's material.
[0044] Furthermore, by matching the target model with the object map of the design drawing, the color area of the target model in the object map is determined. When the color area of the target model in the object map is a replaceable area, the material textures of the target model are loaded. From each material texture, the target material texture corresponding to the material selection command is obtained. Thus, by determining that the color area of the target model in the object map is a replaceable area, the corresponding material texture is loaded for target material texture selection. This allows users to avoid accidental material changes by setting the model's color, thereby improving the accuracy of material changes.
[0045] Furthermore, by determining that the target model's corresponding color area in the object graph of the design drawing is a replaceable area, and then hiding the model whose corresponding color area in the object graph is a non-replaceable area, it is possible to avoid loading the model whose corresponding color area in the object graph is a non-replaceable area when performing subsequent material replacement operations, thereby reducing the amount of resources consumed by the GPU.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0054] The following will provide a detailed description and explanation of the model material replacement method and apparatus for the design drawings provided in this application through several specific embodiments.
[0055] In one embodiment, a method for changing the model material in a design drawing is provided. This method is applied to a terminal device to change the model material in the design drawing. The terminal device can be a desktop terminal or a mobile terminal; a mobile terminal can be a laptop computer, mobile phone, smartwatch, or other portable terminal.
[0056] like Figure 1 As shown in the figure, the method for changing the model material of a design drawing provided in this embodiment includes:
[0057] Step 101: Based on the received material selection instructions, determine the target model from the various models in the design drawing;
[0058] Step 102: Obtain the target material texture corresponding to the material selection instruction from each material texture of the target model;
[0059] Step 103: Merge the material texture with the lighting map, diffuse map and reflection and refraction map of the design drawing to obtain the model image of the target model in the design drawing;
[0060] The design drawing is an image obtained through rendering;
[0061] The light map, the diffuse reflection map, and the reflection and refraction map are the layers obtained after the design drawing is rendered.
[0062] After receiving a material selection instruction, the target model is determined from each model in the design drawing. Based on the material selection instruction, the corresponding target material texture is determined from each material texture map of the target model. The target material texture is then merged with the lighting map, diffuse map, and reflection and refraction map of the design drawing to obtain the model image of the target model in the design drawing. Thus, after generating the design drawing with only one rendering, when changing the material of any model in the design drawing, the layers of the design drawing and the material texture of the model can be directly merged to obtain the model image of the model with the changed material. There is no need to re-perform lighting, diffuse, and reflection and refraction calculations when changing the model's material, thereby reducing the amount of calculation required when changing the model's material in the design drawing and reducing the resources required when changing the model's material.
[0063] In one embodiment, the design drawing is an image obtained after offline rendering, which loads the geometric data of each model, i.e., the image of the model. Each model can be divided into custom models and finished models. Custom models can include walls, floors, ceilings, floor tiles, tile joints, and cabinets, etc., while finished models can include sofas, tables, ornaments, and paintings, etc.
[0064] After obtaining the design drawing through offline rendering, the various layers can be extracted from the design drawing, including a light map that records the brightness of the object illuminated by light; a diffuse reflection map that records the diffuse reflection results; and a reflection and refraction map that records shadows and reflections and refractions. The extracted layers are then saved.
[0065] After obtaining the design drawing, upon receiving a material selection instruction from the user, the model specified by the material selection instruction in the design drawing is identified as the target model. The material selection instruction includes a selection operation, which can be a click operation. For example, when a user clicks on a specific floor tile in the design drawing, that clicked tile is identified as the target model.
[0066] In one embodiment, the terminal device may store material textures for any model. These material textures can be loaded onto the terminal device's display interface. After determining a target model, the terminal device can select the corresponding material textures for that target model and load them onto the terminal device's display interface.
[0067] Considering that the number of texture maps may be large, in one embodiment, the terminal device can pre-record the ID of each model. After determining the target model, the terminal device can send the ID of the target model to the server to receive the texture maps of the target model fed back by the server based on the ID. There is no need to store the texture maps of all models locally, thereby reducing the storage pressure on the terminal device.
[0068] After obtaining the material textures of the target model, these textures can be loaded onto the user interface of the terminal device for the user to select. For example, such as... Figure 2 As shown, the arrows indicate user clicks. When a user clicks on a floor tile, the tile's ID is sent to the server, which then retrieves the tile's texture maps and displays them in the texture display area on the left side of the user interface.
[0069] After obtaining the material textures of the target model, the selected material texture is selected according to the material selection command, such as clicking on any material texture. The clicked material texture is then used as the target material texture corresponding to the material selection command.
[0070] To avoid incorrect material selection when changing the model's material, leading to accidental material changes, in one embodiment, such as... Figure 3 As shown, from each material texture map of the target model, the target material texture map corresponding to the material selection command is obtained, including:
[0071] Step 201: Determine that the color area corresponding to the target model in the object map of the design drawing is a replaceable area, and load each of the material textures of the target model;
[0072] Step 202: Obtain the target material texture corresponding to the material selection instruction from each of the material texture maps;
[0073] The object diagram records color regions that correspond one-to-one with each of the models in the design diagram.
[0074] Considering that not all models require material replacement, in one embodiment, after generating the design drawing, an object map including the color regions of each model can be generated based on pre-defined colors for each model. For example, if all finished models are pre-defined as black, the floor as light blue, the walls as red, and the bricks as green, then after generating the design drawing, all finished models in the design drawing are replaced with black, the floor with light blue, the walls with red, and the bricks with green. This results in an object map including black finished models, light blue floors, red walls, and green bricks. Simultaneously, whether the materials of different color regions can be replaced can be pre-defined. For example, the black color region can be set as non-replaceable, while the light blue color region can be set as replaceable. Thus, when the user-selected model belongs to the light blue color region in the object map, the material of that model can be replaced. The color regions corresponding to each model and whether the materials of each color region can be replaced can be set according to actual conditions.
[0075] When the target model is obtained, based on its position in the design drawing, it is matched against various color regions in the object drawing to determine its specific color region. If the target model's color region is replaceable, such as a light blue region, it indicates that the target model's material can be replaced. In this case, the material textures of the target model are loaded and displayed as shown in the image. Figure 2 The texture display area shown is then used to select any material texture in the texture display area according to the material selection command. The selected material texture in the texture display area is then determined as the target material texture of the target model.
[0076] By matching the target model with the object map of the design drawing, the color area of the target model in the object map is determined. When the color area of the target model in the object map is a replaceable area, the material textures of the target model are loaded. From each material texture, the target material texture corresponding to the material selection command is obtained. By determining that the color area of the target model in the object map is a replaceable area, the corresponding material texture is loaded for target material texture selection. This allows users to avoid accidental material changes by setting the model's color, thus improving the accuracy of material changes.
[0077] To further reduce the amount of GPU resources consumed during material replacement, in one embodiment, after determining that the color area corresponding to the target model in the object graph of the design drawing is a replaceable area, the method further includes:
[0078] Hide the model in each specified area of the design drawing;
[0079] Wherein, the designated area is a non-replaceable area in the object diagram corresponding to the color area.
[0080] For example, the target model is a floor tile, and its corresponding color area in the object graph is red, indicating that it is a replaceable area. In this case, the model whose corresponding color area in the object graph is non-replaceable is obtained from the design drawing. For example, the model located in the black area in the object graph is the finished product model. These finished product models are then hidden in the design drawing, while the area of the finished product model in the design drawing is displayed in black. For example, if the cost model is a sofa and a table, after hiding them, they can be replaced by their colors in the object graph, eliminating the need for sofa and table models.
[0081] By determining that the target model's corresponding color area in the object graph of the design drawing is a replaceable area, the model whose corresponding color area in the object graph is a non-replaceable area is hidden. This eliminates the need to load the model whose corresponding color area in the object graph is a non-replaceable area when performing subsequent material replacement operations, thereby reducing the amount of GPU resources consumed.
[0082] In one embodiment, if it is determined that the color area corresponding to the target model in the object image of the design drawing is a non-replaceable area, the current image of the target model in the design drawing is determined as the model image of the target model in the design drawing.
[0083] For example, if the color region corresponding to the target model in the object image of the design drawing is determined to be a non-replaceable region, such as a black region, then the pixels of the target model are directly collected from the design drawing, and the collected pixels are then used as the model image of the target model in the design drawing. That is, the target model in the non-replaceable region is not modified.
[0084] In one embodiment, after obtaining the target material texture map, the target material texture map can be overlaid with each layer of the design drawing, namely the lighting map, diffuse reflection map and reflection and refraction map of the design drawing, so as to obtain the model image of the target model in the design drawing.
[0085] For example, after obtaining the target material texture, it can be overlaid with a lighting map to obtain a lighting effect map, and simultaneously overlaid with a diffuse reflection map to obtain a diffuse reflection effect map, and overlaid with a reflection and refraction map to obtain a reflection and refraction effect map. Then, the lighting effect map, diffuse reflection effect map, and reflection and refraction effect map are overlaid to obtain the model image of the target model in the design drawing.
[0086] To acquire model images more effectively, in one embodiment, such as Figure 4 As shown, the target material texture is merged with the lighting map, diffuse map, and reflection and refraction map of the design drawing to obtain the model image of the target model in the design drawing, including:
[0087] Step 301: Based on the target area where the target model is located in the design drawing, obtain the light color, diffuse color, and reflective color of the target area from the light diagram, the diffuse reflection diagram, and the reflection and refraction diagram;
[0088] Step 302: Color the target model according to the light color, diffuse color, reflective color, and target material texture to obtain the model image of the target model in the design drawing.
[0089] In one embodiment, after determining the target material texture, the target area where the target model is located in the design drawing is first obtained. For example, let the vertex position of the target model in the design drawing be position, and let the position of the target model in the design drawing be modelMatrix. By converting the vertex position from the model space coordinate system to the world coordinate system, the target area where the target model is located in the design drawing can be obtained as worldPos = modelMatrix * vec4(position, 1.0).
[0090] After determining the target area of the target model, the first area corresponding to the target area in the light map, the second area corresponding to the target area in the diffuse map, and the third area corresponding to the target area in the reflection and refraction map are determined. After determining the first area, the color of the target area is obtained by color sampling of the first area using the textureCube method; the diffuse color of the target area is obtained by color sampling of the second area of the diffuse map using texture2D; and the reflection and refraction color of the target area is obtained by color sampling of the third area of the reflection and refraction map using the textureCube method.
[0091] After obtaining the light color, diffuse color, and reflective color of the target area, the target model can be colored according to the light color, diffuse color, reflective color, and target material texture, thereby obtaining the model image of the target model in the design drawing.
[0092] To further improve the display effect of the model image after material replacement, in one embodiment, the target material texture is colored according to the light color, diffuse color, and reflected refraction color to obtain the model image of the target model in the design drawing, including:
[0093] Multiply the light color by the diffuse color to obtain the first color value;
[0094] The first color value is superimposed with the reflected and refracted color to obtain the second color value;
[0095] The target material texture is colored according to the second color value to obtain the model image of the target model in the design drawing.
[0096] In one embodiment, after obtaining the light color, diffuse color, and reflected / refracted color of the target area, the light color totalLight and the diffuse color diffuse are multiplied to obtain a first color value multiply = diffuse * totalLight. Then, the first color value multiply is added to the reflected / refracted color compositeMp to obtain a second color value multiply' = multiply + compositeMp. After obtaining the second color value multiply', it is assigned to the fragment shader. The target model loaded with the target material texture is then rendered based on the second color value to obtain the model image of the target model in the design drawing.
[0097] The following describes the model material changing device for the design drawing provided in this application. The model material changing device for the design drawing described below and the model material changing method for the design drawing described above can be referred to in correspondence.
[0098] In one embodiment, such as Figure 5 As shown, a model material changing device for a design drawing is provided, including:
[0099] The target model determination module 210 is used to determine the target model from the various models in the design drawing according to the received material selection instructions;
[0100] The material texture acquisition module 220 is used to acquire the target material texture corresponding to the material selection instruction from each material texture of the target model;
[0101] The model material replacement module 230 is used to merge the target material texture with the lighting map, diffuse map and reflection and refraction map of the design drawing to obtain the model image of the target model in the design drawing;
[0102] The design drawing is an image obtained through rendering;
[0103] The light map, the diffuse reflection map, and the reflection and refraction map are the layers obtained after the design drawing is rendered.
[0104] After receiving a material selection instruction, the target model is determined from each model in the design drawing. Based on the material selection instruction, the corresponding target material texture is determined from each material texture map of the target model. The target material texture is then merged with the lighting map, diffuse map, and reflection and refraction map of the design drawing to obtain the model image of the target model in the design drawing. Thus, after generating the design drawing with only one rendering, when changing the material of any model in the design drawing, the layers of the design drawing and the material texture of the model can be directly merged to obtain the model image of the model with the changed material. There is no need to re-perform lighting, diffuse, and reflection and refraction calculations when changing the model's material, thereby reducing the amount of calculation required when changing the model's material in the design drawing and reducing the resources required when changing the model's material.
[0105] In one embodiment, the material texture acquisition module 220 is specifically used for:

[0115] Based on the target area where the target model is located in the design drawing, the light color, diffuse color, and reflective color of the target area are obtained from the light diagram, the diffuse reflection diagram, and the reflective refraction diagram.
[0116] The target model is colored based on the light color, diffuse color, reflective color, and target material texture to obtain the model image of the target model in the design drawing.
[0117] In one embodiment, the model material changing module 230 is specifically used for:
[0118] Multiply the light color by the diffuse color to obtain the first color value;
[0119] The first color value is superimposed with the reflected and refracted color to obtain the second color value;
[0120] The target model is colored according to the second color value and the target material texture to obtain the model image of the target model in the design drawing.
[0121] In one embodiment, the model includes a customized model and a finished product model;
[0122] The customized model includes walls, floors, ceilings, bricks, and cabinets;
[0123] The finished product models include sofas, tables, and decorations.

Figure 6 As shown, the electronic device may include: a processor 810, a communication interface 820, a memory 830, and a communication bus 840, wherein the processor 810, the communication interface 820, and the memory 830 communicate with each other via the communication bus 840. The processor 810 can call a computer program in the memory 830 to execute a method for changing the model material of the design drawing, such as including:
