基于网格的织物虚拟场景真实感模拟及计算机实现

Simulation and Computer Realization of the Three Dimension of Fabric in Virtual Environment Based on Mesh Model

提出并实现了一种在虚拟场景中进行织物真实感模拟的方法。针对图像形式的特定场景,先确定要进行处理区域的边界,建立区域网格,对网格进行必要的拉伸、旋转等变换;然后进行纹理映射,同时保留场景原有的明暗度关系。运用这种方法建立的织物场景模拟,可使织物设计者能够迅速地检查设计效果,为织物虚拟地展示提供了工具,具有良好的实用性。

A new method of 3D simulation of fabric in virtual environment based on mesh model is brought forward and realized. According to the special scene of image form, firstly the area borderline to be deal with is made certain and the area mesh is established, as well as some eounterchanges of mesh such as necessary stretch, rotation are done. And then, cloth texture mapping is in the progress, at the same time the intrinsic relation of light and shade of scene is saved. Based on this scene simulation of fabric the design effect can be checked quickly by the fabric designer. And the simulation provides a tool for fabric show in virtual environment, so it has good practicability.
