A digital design method for 3D prototype clothing

Abstract

The invention provides a digital design method for three-dimensional prototype clothing, including: establishing a PHBC model conforming to the characteristics of the human body; obtaining information on the characteristics of the human body based on the PHBC model; According to the given amount of looseness, the scaling parameters of the required horizontal sections are calculated, and all the sections are scaled according to the scaling parameters to obtain an edge frame with looseness distribution; the developable surface is modeled through the edge frame, according to the available Developable 3D prototype garments are constructed using the developed surface model. Through this method, a 3D model base sample that can be flattened is realized, and thus the garment directly obtains a 2D sample, thereby improving the efficiency of patterning and repairing; obtaining more in-depth feature data of the human body, and using curved surfaces to aggregate Based on the analysis method of class and surface geometric characteristics, the three-dimensional human body data is deeply analyzed; a clothing structure conforming to the human body is designed.

Description

technical field [0001] The invention relates to the technical field of clothing design, in particular to a digital design method for three-dimensional prototype clothing. Background technique [0002] The degree of clothing fit is an important factor for consumers to purchase clothing products, and the degree of fit largely depends on the plate-making techniques and methods of clothing samples. At present, clothing samples are generally hand-drawn by designers. Due to the differences in the experience of designers in making panels, this process often requires a lot of time or repeated procedures to meet the requirements of the correct fit of clothing. [0003] The development of computer-aided design (Computer-Aided Design, CAD) has enhanced the accuracy and easy storage of clothing samples, and improved the convenience of modification. However, compared with traditional hand-drawn boards, CAD technology has not greatly improved the model-making process, and the accuracy an...

Problems solved by technology

[0007] In the process of research, the inventor found that the templates generated by using computer 3D human body data cannot be practically applied in the industry, nor can it be connected with the traditional way of making clothes with panels. The reasons are as follows: 1. Only from the perspective of computers and geometry 3D clothing is constructed from different angles, without considering the relationship between clothing and human body characteristics, and without effective analysis and integration; 2. Most of the models generated by using 3D clothing are in irregular shapes, which are very different from traditional clothing models , cannot be combined with the traditional actual garment production; 3. The model does not meet the requirements of the basic structure of the garment; 4. There is no systematic fit verification;

[0008] The use of physical methods to design and construct three-dimensional surfaces often cannot provide high accuracy, and the parameters and initialization status of the model will also affect the quality of the final two-dimensional template generation; The error is reduced, but usually the generated templates are irregular shapes or only convex polygons, which cannot be applied to clothing samples

Therefore, using physical or geometric methods to construct developable 3D surfaces has its own limitations
