Description

Technical Field

[0001] The present invention relates to the technical field of digital fashion design, and particularly to a fashion design system for rendering the material details of clothing through computer Background Art

[0002] With the rapid development of computer graphics and virtual reality technologies, the applications of digital fashion design and virtual fitting in the fashion industry and e-commerce have become increasingly widespread; the traditional fashion design process usually relies on the production and fitting of physical samples, which not only consumes a large amount of time and resources, but also limits the creative expression of designers and the personalized needs of consumers; to solve these problems, many software tools have begun to introduce digital fashion design and fitting functions, allowing designers and users to create, modify and display clothing in a virtual environment.

[0003] Currently, three-dimensional virtual clothing display still has significant limitations in several key technical fields, especially in the detailed performance of material rendering, model selection and body shape adaptation, and dynamic fitting experience, etc.; for example, in the rendering of clothing materials, most of the existing technologies rely on traditional material simulation models and cannot accurately restore complex optical properties, such as the reflection, refraction, transparency of materials and the microscopic details of surface textures; especially for some materials with high gloss, transparency or complex textures, such as silk, leather, tulle, etc., the existing systems still have obvious deficiencies in simulating their surface gloss, texture distribution, refraction effects, etc., which results in the clothing rendering effect not being realistic enough and unable to effectively enhance the user's immersion and design experience.

[0004] In addition, the model selection and body shape adjustment functions of existing systems are often limited to a few standardized body shapes and cannot meet the needs of diverse user groups; especially when considering diversified factors such as different races, genders, ages, heights, weights and special body shapes, the existing technologies lack flexible and precise body shape customization capabilities and cannot fully achieve the personalized needs of users; the existing body shape adjustment functions are mostly rough size modifications and cannot be refined to specific parts, such as chest circumference, waist circumference, hip circumference, leg circumference, etc., and cannot provide sufficient accuracy and authenticity for important details such as the adaptability and fitting sense of clothing after body shape adjustment, thus reducing the application potential of digital fashion design systems in the fields of personalized customization and virtual fitting.

[0005] Meanwhile, most of the existing dynamic fitting simulation functions rely on static models and fail to fully consider the performance and changes of clothing under different movements and postures. During the movement of clothing, due to the influence of physical properties (such as elasticity, wrinkles, stretching, etc.), its appearance and fitting effect will change significantly. There are obvious technical bottlenecks in such dynamic simulations in the existing systems, making it difficult to truly reproduce the deformation effect of clothing during movement and its interaction with the human body shape, resulting in users being unable to obtain an accurate fitting experience and thus affecting the practical use value of the system. Summary of the Invention

[0006] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a clothing design system that renders the material details of clothing through computer, so as to solve the problems that the existing systems can neither accurately reproduce the gloss, texture and transparency of different materials, nor are limited in the functions of model selection and body shape adjustment.

The model body shape adjustment sub-module includes an automatic adaptation mode, and the automatic adaptation mode is used to automatically adjust the body shape of the model according to the selected clothing style to ensure the realism of the clothing wearing effect.

[0027] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0028] Please refer to Figures 1 to 6 , the present invention provides a clothing design system for rendering clothing material details by computer, which is applied to multiple fields such as virtual reality (VR), augmented reality (AR), e-commerce, digital design, and clothing customization. Through efficient rendering and simulation algorithms, it provides users with realistic clothing detail display and fitting experience, including a clothing design module, a model selection and adjustment module, a clothing material rendering module, and a rendering result display and output module.

[0029] The clothing design module includes a clothing structure design sub-module and a clothing material application sub-module. The clothing structure design sub-module is used to construct and adjust the basic structure and style of the clothing, and the clothing material application sub-module is used to apply different material textures to the designed clothing structure; among them, the clothing structure design sub-module supports users to select the clothing structure from the preset templates of drawing software or create a customized clothing style by manual drawing and editing. The clothing material application sub-module supports multi-layer texture overlay and transparency adjustment to enhance the realism of the clothing material;

[0030] It should be noted that the steps of constructing and adjusting the basic structure and style of the clothing in the clothing structure design sub-module are as follows: combining existing clothing design software such as clo 3d, style 3d, etc. to design the clothing style required by the customer, drawing or importing a 2D clothing pattern, and using tools to draw the basic clothing fabric parts (such as the body, sleeves, trouser legs, etc.); it is also possible to modify the existing clothing template and use the measurement tools in the software to ensure that the size and proportion of the 2D pattern meet the expectations. After completing the pattern design, use the sewing tool of the software to sew the individual 2D pieces together;

[0031] The steps to apply different material textures to the designed clothing structure in the material application sub-module are as follows: In C4D, to apply materials to specific details of the clothing, it can be achieved by selecting local areas of the clothing model and setting material restrictions: First, create or import the required materials and adjust their parameters such as color and texture; then, in polygon mode, select the clothing detail areas where the materials are to be applied (such as cuffs, collars, etc.), right-click and select "Set Selection" to generate a selection tag, drag the material onto the entire clothing model, and enter the corresponding selection tag name in the "Selection" field of the material tag to ensure that the material is only applied to the selected areas; if there are problems with the material display, the display effect can be optimized by adjusting the UV mapping or other texture projection methods.

[0032] As can be seen from the above solution, the clothing design module supports users to design and adjust the basic structure and style of clothing. Users can choose from preset templates or create customized clothing styles by manual drawing and editing. This clothing design module also supports applying different materials to the designed clothing and previewing the final effect in real time.

[0033] The model selection and adjustment module includes a model selection sub-module and a model body type adjustment sub-module. The model body type sub-module is used to customize a suitable virtual model from a preset model library, and the model body type adjustment sub-module is used to adjust the body type proportion and pose of the virtual model according to the body type parameters input by the user; among them, the model selection sub-module is used to provide multiple model selection options, including gender, age, height, weight, and other body type characteristics. The model body type adjustment sub-module includes an automatic adaptation mode, which is used to automatically adjust the body type of the model according to the selected clothing style to ensure the realism of the clothing wearing effect.

[0034] It should be noted that the steps to adjust the body type proportion and pose of the virtual model according to the body type parameters input by the user in the model body type adjustment sub-module are as follows: In zbrush or daz studio, to adjust the body type proportion and pose of the 3D model according to the provided human body type parameters, it can be achieved by using the built-in adjustment tools and deformation functions; in zbrush, the deformation tools inside (such as "Size", "Rotate", and "Move") can be used to adjust the proportion and pose of the model according to the parameters input by the user, and more precise body type adjustment can be achieved by using Morph Targets and Blend Shapes; in daz studio, the parameter panel can be directly used to change the body type proportion and pose of the model by adjusting the sliders. These sliders control the preset body type transformation and pose adjustment, enabling the model to change quickly according to the input parameters.

[0035] As can be seen from the above solution, the model selection module allows users to customize a virtual model with an ideal body shape from a variety of preset models; the model selection module supports diverse model options, including gender, age, height, weight, and other body shape characteristics, to meet the needs of different users; after selecting a model, users can further adjust the body shape parameters of the model through the model body shape adjustment module, which allows users to adjust the body proportion, posture, etc. of the model according to specific needs to better simulate the wearing effect of clothing on different body shapes.

[0036] The clothing material rendering module includes a texture mapping sub-module, a normal map sub-module, a lighting simulation sub-module, and a material property adjustment sub-module; the texture mapping sub-module is used to map the two-dimensional image texture of the clothing material onto the three-dimensional clothing model, the normal map sub-module is used to generate the bumpy detail effect of the clothing material, the lighting simulation sub-module is used to simulate the light reflection effect of the clothing material according to the direction and intensity of the light source, and the material property adjustment sub-module is used to adjust the material property parameters after rendering and export the material rendering setting content according to the user's needs; among them, the texture mapping sub-module includes a mode for supporting multi-layer texture overlay to enhance the realism of the clothing material, the normal map sub-module is used to generate a highly detailed bumpy effect based on high-precision normal map data, the lighting simulation sub-module includes a real-time lighting calculation mode, and the real-time lighting calculation mode is used to dynamically update the rendering effect of the clothing material when the user adjusts the light source position. The material property adjustment sub-module can preview the material effect after adjustment in real time and adjust the previously set rendering parameters through the material sphere, which can increase the realism of the clothing material;

[0037] It should be noted that: the steps for mapping the two-dimensional image texture of the clothing material onto the three-dimensional clothing model in the texture mapping sub-module are: achieving through UV mapping or adjusting the texture projection mode; unwrapping the UV of the clothing model and applying the two-dimensional image as the material to the clothing model; selecting UV Mapping as the projection method in the material settings and adjusting the UV unwrapping to ensure that the texture fits correctly. If UV mapping is not used, a texture projection mode suitable for the clothing model (such as cube mapping, planar mapping, etc.) can be selected and the texture coordinates can be adjusted to match the model surface; the steps for generating the bumpy detail effect of the clothing material in the normal map sub-module are: using a normal map or a bump map, creating or importing the material, and adding a normal map or a bump map to the corresponding channel (such as the "bump channel" or the "normal channel") in the material editor; the normal map will simulate the bumpy feeling of the details during rendering, while the bump map directly affects the surface details of the model; adjusting the intensity and direction of the map to obtain the desired bumpy effect, which can make the clothing material present more realistic detail effects during rendering;

[0038] The steps to simulate the light reflection effect of clothing materials according to the direction and intensity of the light source in the light simulation sub-module are as follows: It is achieved by adjusting the reflection properties of the material; in the material editor, turn on and adjust the reflection channel, set the reflection intensity and reflection glossiness, and at the same time, an environment map can be used to enhance the light reflection effect, and the direction, intensity, and type of the light source (such as point light source, parallel light source, etc.) are determined through the light source settings to simulate different lighting conditions, so that the material will show a real light reflection effect according to the light source settings;

[0039] As can be seen from the above solution, the clothing material rendering module includes sub-modules such as texture mapping, normal map, and light simulation, which can accurately render the details of different materials, such as gloss, texture, and transparency. Through these technical means, the system can simulate the real appearance of various materials such as silk, cotton, and leather, making the display effect of virtual clothing more realistic.

[0040] The rendering result display and output module is used to display the final effect in multi-angle and dynamic views after rendering; it should be noted that the clothing material rendering module can perform high-resolution real-time rendering on the clothing model after material application and body shape adjustment, and display the final effect in multi-angle and dynamic views in the rendering result display and output module.

[0041] Specifically, the present invention combines multiple professional software tools to achieve the purpose of rendering the details of clothing materials, model selection and body shape adjustment, and clothing structure design; the following describes the specific implementation manners of the present invention, including the detailed steps of using CLO 3D or Style 3D to design clothing structures, using DAZ or ZBrush to adjust the 3D model of the model, and using C4D for rendering.

[0042] (1) Garment structure design: Users first use CLO 3D or Style 3D software to create the basic structure of the garment. Both CLO3D and Style 3D are highly specialized garment design software that support the construction of garment shapes and styles through 2D pattern making and 3D modeling. During the design process, users can choose from a variety of preset garment templates, or manually edit details such as cut pieces, seams, and folds to create a custom garment structure. After the design is completed, users can use the software's material application function to apply different material textures to the designed garment to simulate the visual effects of materials such as silk, cotton, and leather. At this stage, the physical properties of the garment, such as softness, thickness, and stretchability, can also be adjusted to more realistically simulate the wearing effect. It should also be explained that the process of clothing structure design is as follows: the designer draws the clothing effect style diagram (line draft / manuscript) based on the reference photo, and then passes the clothing effect style diagram and clothing structure diagram (DXF pattern file) through the virtual + AI workflow. The virtual + AI workflow is to complete the entire design process from creativity to production through virtual simulation technology and AI rendering algorithm combined with clothing design, pattern making, simulated fitting and other links; then the work is allocated, and clothing surface stitching (3D style stitching) and clothing surface printing, rivets, buttons, etc. (reference picture collection) are completed in combination with clothing design software. Finally, the above process is used to achieve a flexible combination of the two (AI-side combination). For details, please refer to Figure 7 ;

[0043] (2) Selection and adjustment of the model's 3D model: After the clothing structure design is completed, the user uses DAZ 3D or ZBrush software to select the model's 3D model and adjust its body shape. DAZ 3D provides a large number of preset model libraries, and users can choose a suitable virtual model based on gender, age, body shape and other parameters. After selecting the model, the user can further refine the model's body parameters through ZBrush software. ZBrush is a powerful 3D sculpting software that allows users to make fine adjustments on high-precision models to ensure that the model's body shape matches the designed clothing. After the model adjustment is completed, the model is exported to a compatible 3D format (such as OBJ, FBX, etc.) for use in the subsequent rendering process.

[0044] (3) Rendering of clothing material details: The user renders the clothing and the model through Cinema 4D (C4D) software; C4D is a professional 3D modeling, animation, and rendering software that supports advanced rendering techniques such as global illumination (GI), ambient occlusion (AO), and subsurface scattering (SSS), making the rendered clothing materials and model effects more realistic; Import the clothing model exported from CLO 3D or Style3D and the model exported from DAZ or ZBrush into C4D. In C4D, the user can further adjust attributes such as the glossiness, transparency, and reflectivity of the material to achieve the best visual effect. C4D's rendering engine allows the user to set complex lighting environments and camera angles to simulate the performance of clothing materials under different lighting conditions; In addition, the user can also simulate the dynamic effects of clothing through the dynamics engine in C4D, such as the folds and natural drooping of the fabric in different poses; It should also be noted that 3D style adjustment is to perform real-time adjustment and optimization of clothing design in a virtual environment by combining 3D clothing design software, specifically including: First, perform virtual pattern modification; Then, perform fabric and material simulation; Then, optimize the pattern and cutting; Then, perform style display and virtual fitting; Finally, perform quick feedback and iteration; Among them, 3D metal part production and 3D material production refer to the design, production, and simulation of metal parts and other materials using 3D modeling software in the digital design and manufacturing process; 3D metal part production is to produce 3D metal parts through computer-aided design (CAD, etc.) modeling software. This process completes the modeling of the geometric shape, structural details, and functional characteristics of the metal parts in a digital way; 3D material production is to create and simulate the appearance and physical properties of different materials (such as fabric, plastic, metal, etc.) in the 3D design and process. For specific details, please refer to Figure 8 ;

[0045] (4) Display and output of rendering results: After rendering is completed, the final effect can be displayed from multiple angles in a high-resolution display module; The user can select different perspectives to view the overall effect of the clothing on the model; The final rendering result can be exported in image or video format for e-commerce display, virtual fitting, or further design review.

[0046] In summary, the present invention combines multiple rendering techniques, including but not limited to texture mapping, normal mapping, bump mapping, and lighting simulation, to realistically reproduce the details of various clothing materials. Therefore, the present invention can accurately simulate the glossiness, roughness, transparency, and texture of clothing materials, making the visual effect more realistic in virtual fitting, e-commerce display, and digital design;

[0047] The present invention allows users to customize a virtual model with an ideal body shape from a variety of preset models to meet the needs of different users. After selecting a model, the body shape parameters of the model can be adjusted to better simulate the wearing effects of clothing on different body shapes; the present invention improves the accuracy and realism of clothing material rendering while reducing the consumption of resources in subsequent clothing design and production; it can flexibly integrate and efficiently render the details of clothing materials through computer software, and provide a rich selection of models and body shape adjustment functions to enhance the realism and user experience of virtual fitting;

[0048] The present invention can flexibly integrate and efficiently render the details of clothing materials through computer software, and provide a rich selection of models and body shape adjustment functions to enhance the realism and user experience of virtual fitting, aiming to overcome the deficiencies in material rendering, model selection, and body shape adjustment in the prior art; the present invention also supports the digital design of clothing structures, enabling designers to create and display innovative clothing styles more flexibly, while reducing the cost and time of physical sample production, with high efficiency and flexibility, and can be widely applied in fields such as virtual reality (VR), augmented reality (AR), and computer-aided design (CAD); through the present invention, users can conduct clothing design and fitting more intuitively and efficiently in a virtual environment, not only saving the time and cost of physical sample production, but also enhancing the realism of clothing display and user experience.

[0049] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
