利用Vray渲染器模拟产品表面海量毛绒、镶嵌物及凹凸形态

Research for Utilization of Vray Renderer Simulate Massive Hairs and Tesseras and Concavo-Convex Forms

针对在产品建模中创建海量三维细节会占用大量内存，导致系统运行缓慢、内存卡死或被迫花费大量经济成本来升级硬件等问题，Vray引擎中的物体类型与置换修改器能够基本解决上述问题。通过实例分析了怎样设置vrayfur物体类型来模拟产品表面成千上万的毛料，同时分析了Vrayproxy物体类型对含有大量三角细分面的宝石模型的代理，最后阐释VRayDisplacementMod置换修改器对产品表面剧烈凹凸形态的创建。结果表明利用Vray引擎可以大量减少对内存资源的消耗，保证海量逼真的产品细节在被轻松表现出来。

Create product three-dimensional model with massive details in will take up a lot of memory, causing system running slow, paralyzing memory or being forced to spend a lot of economic cost to upgrade hardware configuration etc. Object type and displacement modifier of Vray engine supplies effective solutions to mentioned above, through specific examples to elaborate on how to set Vrayfur object to simulate thousands of woolen goods of surface, and analyzing Vrayproxy objects how to proxy gem model which contains a lot of subdivision triangle surfaces, finally explaining VRayDisplaeementMod modifier how to create se- vere coneavo-convex form of product face. The results show that utilization of Vray engine can efficiently conserve ememory, en- sure Massive realistic product details are easily demonstrated.
