Embodiment Construction

[0032] The method of the present invention will be further described below in conjunction with specific examples.

[0033] The method for opening a three-dimensional toy model based on a component template of the present invention mainly includes the following steps:

[0034] 1) Select commonly used toy part models and build a toy part template library. For each component in the template library, draw a dividing line on its surface, calculate its shape descriptor, and perform spherical parameterization on the model;

[0035] 2) Read in a 3D toy model based on the combination of components;

[0036] 3) For each part of the three-dimensional toy model, search for the most similar parts in the template library, perform spherical parameterization on the three-dimensional part model, and map the dividing line of the part template to the surface of the three-dimensional part model;

[0037] 4) Automatically generate intersection lines between three-dimensional toy parts;

[0038]...

Abstract

The invention discloses a three-dimensional toy model opening method based on a component template, which aims at a three-dimensional toy model designed by adopting a component combined type modelingmethod, and comprises the following steps of: firstly, storing a common design method of a surface parting line of the three-dimensional toy model into a component template library in a template form;when a new toy is designed, for each part of the toy, automatically searching the most similar part from the part template library, and automatically mapping the segmentation line in the part template to the new part, so that automatic edition opening is realized, the design efficiency is improved, and the difficulty of learning toy design is reduced. The method is not only suitable for designingcloth toys, but also suitable for designing toys made of all sewable soft materials such as leather, leather and the like, and can be widely applied to the field of toy design.

Description

technical field [0001] The invention relates to a pattern-making method of a toy, in particular to a pattern-making method of a three-dimensional toy model based on a component template. Background technique [0002] The design and production process of cloth toys includes steps such as pattern opening, cloth cutting, and sewing. Among them, the pattern-making is to design the two-dimensional paper pattern or cut piece of the toy, which is an essential key step in the design and production of the toy. For a long time, toy pattern making has been done by traditional handwork, that is, with the designer's spatial imagination and practical experience, the imaginary three-dimensional model of the toy is designed by hand into a flat paper pattern. Competence and practical experience are very demanding. In actual operation, often due to the lack of spatial imagination or practical experience of the designer, the designed pattern does not meet the requirements and needs to be rev...
