[0045] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0046] Figure 1 1 is a flow chart of a model file generation method provided by an embodiment of the present invention. The model file generation method may include the following steps S101-S104.

[0047] Before executing step S101 , a component customization library and a material library may be created first.

[0048] First, the process of making a component customization library is briefly explained using furniture as an example.

[0049] Before executing step S101, the model file generation method also includes: establishing a first type of component and a second type of component; configuring a corresponding identifier for each of the first type of component and the second type of component; and associating the identifier of each of the first type of component and the second type of component under the model to be displayed.

[0050] Specifically, first, according to the actual furniture design, each replaceable component is modeled in a synthesis tool (such as 3ds max) and exported into obj format. The replaceable components may include first-class components (such as Figure 2 Type A components shown in the figure) and Type II components (such as Figure 2 Specifically, any one of the first-type components may be configured with at least one style and at least one material (i.e., a type of component with replaceable style and replaceable material), for example, Figure 2 The style and material of the panels or shutters in the second type of components are replaceable. Any of the second type of components is configured with at least one style (i.e., a type of component that can replace the style but not the material), for example, Figure 2 The style of the sink or handle is replaceable but the material is not. Then, a unique identifier (for example, handle ID01, sink ID02, etc.) is configured for each of the first type of components and the second type of components, and the obj format components and corresponding identifiers are stored in the component customization library and associated with the identifier of the same furniture model (for example, cabinet model ID). Then, the identifiers of multiple replaceable materials configured for the same component can also be associated with the component, that is, the identifiers of different replaceable materials can be the first sub-identifier of the identifier of the component. For example, the dark walnut identifier of the handle is ID01-1-1, the hardwood identifier of the handle is ID01-1-2, and the walnut identifier of the handle is ID01-1-3, etc.; the dark walnut identifier of the sink is ID02-1-1, the hardwood identifier of the sink is ID02-1-2, and the walnut identifier of the sink is ID02-1-3, etc.

[0051] Secondly, the process of making a material library is briefly introduced.

[0052] For all components used in the material (such as Figure 2 The dark walnut, hardwood, walnut, white ash, ash and other materials shown in the figure are generated by material tool software. Then, each material is assigned a unique material identifier (such as material ID), and each material and the corresponding identifier are stored in the material library. Each material contains three maps: color (BaseColor), normal (Normal) and mixed map (AO_M_R). Among them, the mixed map contains roughness (Roughness), metal (Metallic), and ambient occlusion (Ambient Occlusion).

[0053] Step S101, selecting a first type of component and a second type of component.

[0054] The identifiers of the first type of components and the second type of components are associated with the model to be displayed, and any one of the first type of components is configured with at least one material (such as Figure 2 You can select a default material for each component. Of course, you can also select a default material for the entire model. For example, the entire cabinet model uses the dark walnut material.

[0055] Specifically, the first type of components (e.g., panels, doors) and the second type of components (e.g., sinks, handles) associated with the cabinet model in the component customization library can be selected, and the first type of components and the second type of components can be imported into a synthesis tool (e.g., 3d max).

[0056] In one embodiment, the first category of components are components of replaceable materials, for example, the default material of the panel may be dark walnut, and its replaceable materials may be walnut, white ash, ash and other materials; while the second category of components are components of non-replaceable materials (whose material may be the default material, for example, dark walnut).

[0057] In another embodiment, any one of the first type of components and any one of the second type of components are configured with at least one style. The first type of components are components with replaceable styles and replaceable materials, for example, the board can be style a or style b, and the material of the board can be walnut, white ash, ash, etc.; while the second type of components are components with replaceable styles but non-replaceable materials, for example, the style of the handle can be style A, style B, etc., but the material of the handle can only be a default material (for example, dark walnut material). Specifically, the identifiers of multiple replaceable styles configured for the same component can be associated with the component, that is, the identifiers of different replaceable styles can be the second sub-identifier of the identifier of the component. For example, the identifier of handle style A is ID01-2-1 and the identifier of handle style B is ID01-2-2, etc.; the identifier of sink style C is ID02-2-1 and the identifier of sink style D is ID02-2-2, etc.

[0058] Step S102: synthesize the first-category components and the second-category components into the model to be displayed.

[0059] For step S102, the step of combining the first type of components and the second type of components into a model to be displayed may include: combining the first type of components and the second type of components into the model to be displayed by using 3d max. Specifically, the selected components are spliced ​​by using 3d max to form a cabinet model.

[0060] Step S103, extracting feature information of each of the first-category components and each of the second-category components.

[0061] The characteristic information at least includes identification and displacement.

[0062] For step S103, the extracting of characteristic information of each of the first category components and each of the second category components may include: extracting the characteristic information of each of the first category components and each of the second category components by traversing the scene where the model to be displayed is located through the extraction plug-in in the 3d max.

[0063] Specifically, the self-made max plug-in can traverse the entire max scene to extract the ID, displacement (i.e., spatial coordinates) and other feature information of each component of the cabinet model. Of course, the feature information may also include scaling and / or rotation (i.e., rotation angle).

[0064] Step S104, recording the characteristic information of each of the first-category components and each of the second-category components, and the information of the at least one material configured for any of the first-category components, to form a model file about the model to be displayed.

[0065] The model file may be a json file.

[0066] Specifically, in one embodiment, the feature information extracted in step S104 and the material IDs of the first type of components (such as panels, shutters and other components) that can be used interchangeably may be written into a json file.

[0067] In another embodiment, when any one of the first type of components and any one of the second type of components are configured with at least one style, the model file generation method may further include: recording information of the at least one style of any one of the first type of components and any one of the second type of components in the model file. That is, the feature information extracted in step S104, the material ID of the first type of components (such as panels, shutters, etc.) that can be used interchangeably, and the ID of at least one style that can be used interchangeably for each component can be written into the json file.

[0068] After obtaining multiple model files (files recording specific feature information about multiple models) in the above manner, the multiple model files can be stored with unique identifiers to form a model library. Specifically, the multiple json files generated by the above steps can be stored in the model library.

[0069] To summarize, the present invention creatively first selects a first type of component and a second type of component, then synthesizes the first type of component and the second type of component into a model to be displayed, then extracts feature information of each of the first type of component and the second type of component, and then writes the feature information of each of the first type of component and the second type of component and information of at least one material configured by any of the first type of components into a model file. Thus, the present invention can generate a model file of components including a variety of replaceable materials, so that the materials of multiple components in the display model can be flexibly replaced by the first type of components and the model file in the generated model file, thereby realizing customized display of the model.

[0070] Figure 3 FIG. 1 is a flow chart of a virtual model display method provided by an embodiment of the present invention. Figure 3 As shown, the virtual model display method may include the following steps S301-S305.

[0071] Step S301, importing the model file generated by the model file generation method into the display tool, and reading the feature information of each of the first category components and each of the second category components of the model to be displayed in the model file, and the information of at least one material configured for any of the first category components.

[0072] The characteristic information may include at least identification and displacement.

[0073] Wherein, the display tool may be a three-dimensional display tool based on Threejs.

[0074] After the previously stored json file is imported into the three-dimensional display tool, the previous json file is read by the three-dimensional display tool, and the ID, displacement and other characteristic information of the first type of components (such as type A components) and the second type of components (such as type B components) used in the cabinet model are identified through this json file. Of course, in the above, if the previous json file also includes scaling and / or rotation, correspondingly, the ID, displacement, scaling and / or rotation and other characteristic information of the first type of components (such as type A components) and the second type of components (such as type B components) used in the cabinet model are identified through this json file (as described below).

[0075] Of course, when a model library is formed by the above-mentioned model file generation method, the corresponding model file (the model file corresponding to the model to be displayed) can be first obtained from the model library, and then the model file (such as a json file) can be imported into the three-dimensional display tool.

[0076] Step S302: Import the first-type component and the second-type component corresponding to the identifier in the feature information and the at least one material configured by the first-type component into the display tool.

[0077] Corresponding components may be imported from a component customization library according to IDs of various components used by the identified cabinet model.

[0078] Step S303: adjusting the positions of the first type of components and the second type of components in the display tool according to the displacement in the characteristic information to generate the object to be displayed.

[0079] The characteristic information may also include scaling and / or rotation. Accordingly, for step S303, adjusting the positions of the first-type components and the second-type components in the display tool may include: determining the position matrix of the first-type components and the second-type components according to the displacement, scaling and / or rotation in the characteristic information; and adjusting the positions of the first-type components and the second-type components in the display tool according to the position matrix of the first-type components and the second-type components.

[0080] The position matrix of each component can be calculated according to the information of displacement, scaling, rotation, etc. of each component, and then the position of each component in the three-dimensional display tool can be adjusted according to the position matrix.

[0081] In another embodiment, when the model file also records information of at least one style configured by any one of the first type of components and any one of the second type of components, after executing step S303, the virtual model display method may further include: selecting a specific style from the at least one style configured by a specific component in the first type of components and / or the second type of components; and replacing the style of the specific component with the specific style (for example, by selecting a different second sub-identifier) ​​to display the object to be displayed. For each component, a default style may be selected. That is, according to the user's preference, a specific style may be selected from the at least one style configured by each component, and the default style may be replaced with the selected specific style.

[0082] Step S304: Select a specific material from at least one material configured for a specific component in the first type of components.

[0083] According to the user's preference, a specific material can be selected from at least one material configured for the Class A components such as the panel and / or the shutter, for example, by selecting a different first sub-identifier.

[0084] If the model file (for example, a json file) is modified, specifically, the replaceable material ID of a component is modified and the modified material ID does not exist in the material library (that is, the material library does not contain a material corresponding to the modified material ID), the default material of the model to be displayed (for example, a cabinet model) is used.

[0085] Step S305: replacing the material of the specific component with the specific material to display the object to be displayed.

[0086] The default material can be replaced with a specific material for the selected panel and / or door type A component.

[0087] After executing step S305, the virtual model display method may further include: adjusting at least one of the displacement, scaling and rotation of the model to be displayed. Specifically, in the three-dimensional display tool, the length, width and height of each component can be adjusted through the operation bar, and the rotation and position of the component can be adjusted.

[0088] After performing the adjustment of at least one of the displacement, scaling and rotation of the model to be displayed, the virtual model display method may further include: storing the identification of the model to be displayed and at least one of the adjusted displacement, scaling and rotation. Specifically, in the three-dimensional display tool, the relevant serialized data of the adjusted cabinet model can be exported (the serialized data may include the ID of each component, feature information and the material used by the Class A component, etc.). In subsequent applications, the adjusted custom model can be restored by importing these serialized data.

[0089] To summarize, the present invention creatively reads the characteristic information of each of the first category components and the second category components of the model to be displayed in the model file and the information of at least one material of each of the first category components after importing the model file into the display tool, and then imports the components corresponding to the identifiers in the characteristic information and the at least one material configured by the first category components into the display tool, and then adjusts the positions of the components in the display tool according to the displacements in the characteristic information to generate objects to be displayed, and finally selects a specific material from the at least one material configured by a specific component in the first category components, and replaces the material of the specific component with the specific material to display the object to be displayed. Therefore, the present invention can flexibly replace the materials of multiple components in the display model, thereby realizing customized display of the model.

[0090] Figure 4 FIG. 1 is a flow chart of a virtual model group display method provided by an embodiment of the present invention. Figure 4As shown, the virtual model group display method may include: step S401, displaying at least two cabinets in the model group to be displayed according to the virtual model display method; step S402, determining the size and position of the combination components of the model group to be displayed according to the boundary boxes of the at least two cabinets; step S403, importing a preset combination component with a preset size into the display tool, and updating the size of the preset combination component according to the size of the combination component; and step S404, adjusting the position of the updated preset combination component in the display tool according to the position of the combination component. Wherein, the combination component is a skirting and / or a countertop.
