A method for manufacturing a seamless splicing pattern simulated litchi pattern leather surface

Abstract

The invention provides a method for manufacturing a seamless splicing pattern simulated litchi pattern leather surface, which comprises the following steps of extracting structural element characteristics of surface textures of the litchi rind leather through a stereo microscope, and selecting the structural element characteristics influencing the surface textures of the simulated litchi rind leather as leather textures and pores; based on the seamless splicing pattern principle and the creation principle of the seamless splicing pattern in the Adobe Illustror, creating the surface dermatoglyph of the litchi pattern leather; creating pores in the surface of the litchi rind leather; and creating a texture map of the litchi pattern leather surface. Under the condition that the programming language and a physical model complex algorithm are not used, the real texture simulation of the litchi pattern leather texture is realized based on universal vector drawing software. By implementing the method and the device, the realistic simulation of the litchi rind leather texture can be realized only by extracting two main characteristics, namely the leather texture and the pores, so that thecomputer calculation running time is objectively reduced, the texture simulation efficiency is improved, and the diversified presentation of the litchi rind leather texture seamless splicing unit is also realized.

Description

technical field [0001] The invention relates to the technical field of computer simulation, in particular to a method for making a seamless collage pattern to simulate the surface of lychee grain leather. Background technique [0002] Litchi pattern is the most widely used leather texture in the design and development of leather products. It has a relatively obvious and irregularly changing concave-convex surface, so it has a relatively strong three-dimensional effect and a relatively good feel; as time goes by, The glossiness of leather products made from lychee grain leather will get better and better, so it is favored by consumers. However, precisely because of its irregularly changing concave-convex surface, it is often difficult for leather product designers to show its true surface characteristics when designing lychee leather products. [0003] Miyata et al. propose a method for creating leather textures using particle simulation and speckle models. The method mainl...
