Abstract

The invention provides a woven grid mark and direction calibration optimization method and device and relates to the field of computer graphics, The isotropic four-sided dominant mesh, that is, the mesh with the same performance value measured in different directions mainly in the quadrilateral, is optimized by two steps of edge marking and direction calibration to obtain an effective woven mesh;the obtained woven grid can be used for manufacturing the prototype of the virtual garment; modeling does not need to depend on a topological structure of an input grid; instead, the optimization operation is performed on the mark and direction calibration; An effective woven grid is generated under the condition that a correct weaving method is kept, the number and the necessity of triangles in afinal woven structure are reduced, the whole process is automatically carried out, detail modification does not need to be carried out through manual interaction, the textile modeling efficiency is improved, and the weaving direction can be rapidly determined.

Description

technical field [0001] The present disclosure relates to the field of computer graphics, in particular to a method and device for weaving grid marking and direction calibration optimization. Background technique [0002] Woven clothing is common in everyday life, from socks, pants and T-shirts to winter sweaters and accessories, besides, it is also common in movies and games. In the field of computer graphics, a large part of the work dealing with cloth is to simulate fabrics with one-sided representations. Current techniques rely on a knitting mesh modeling framework, which is an abstract yarn-level geometry, an intermediate product for creating a yarn-level model, which provides a mesh-based yarn-level knitting geometry It enables the efficient design of complex 3D weaving models with the correct yarn-level topology so that they can be used with yarn-level simulations. However, this framework relies heavily on the topological structure of the input mesh. Based on this, t...
