在计算机图形应用中，包含实时移动和执行动作的人的虚拟环境是无处不在的。这样的人物通常穿着机织的布料。本文提出了一种在实时可视化机织服装的同时优化真实感外观的技术。该方法通过采用纺织计算机辅助设计(CAD)的织造信息文件(WIF)来表示织造的语法，从而支持复杂的织造图案的绘制。我们将从WIF获得的语法表示与程序线程纹理、合适的布料双向反射分布函数(BRDF)和地平图相结合，开发了一种逼真的渲染方案。为了满足实时性的要求，我们采用了多纹理方法。因此，我们可视化编织衣服的方法从编织语法规范开始，并将其转换为可应用于衣服的纹理。通过实例说明了该方法的通用性。
Virtual environments containing humans moving and performing actions in real time are ubiquitous in computer graphics applications. Such characters are often clothed in woven fabrics. This paper presents a technique for visualizing woven clothes in real time, while optimizing the realistic appearance. The proposed approach supports rendering of complex weave patterns by adopting Weaving Information File (WIF), a standard from textile Computer Aided Design (CAD) for representing the grammar of weaving. We develop a realistic rendering scheme by combining the grammar representation obtained from the WIF with a procedural thread texture, a suitable cloth Bi-directional Reflectance Distribution Function (BRDF) and horizon maps. We employ the multi-texturing approach to meet the real time constraint. Thus our approach to visualizing woven clothes begins from weaving grammar specifications and converts them into textures that can be applied on clothes. We demonstrate the versatility of the proposed approach with examples.
