在三维动画制作过程中,材质是视性属性的综合体现,是表现视觉艺术效果的关键之一.Renderman是一款在好莱坞的动画片中广泛应用,技术成熟并提供接口扩展的一流渲染器.阐述了利用Renderman的rsl语言编写shader的原理、方法和实践,并且给出了利用几何理论、分形理论、物理学等知识结合运用,在三维动画片中,用Renderman中几个材质制作应用实例,特别是完整地给出了一种丝绸材质算法.

During the implementation of three-dimensional cartoons, shaders are one of the important keys in artistic effect. Renderman is a rendering software widely used in Hollywood with its advantages of interface extension and mature technology. The principle, method and practice of shader programming by rsl of Renderman are clarified. The knowledge of fraction, algbraeet, geometry and physics is applied, and a few application examples in three-dimensional cartoon《7℃ 》are presented. An arithme...
