Maya & mental ray全局照明(GI)和焦散效果渲染设置全面教程

The Gnomon Workshop – Global Illumination and Caustics in Maya & mental ray
在这次教程中，作者展示了多种技术，在Maya和mental ray卟使用全局照明和焦散。全局照明和焦散渲染技术利用光子来创建自然采光现象的方法。光子为基础的照明让光线反弹和创建复杂的效果，是不可能与其他渲染方法。与全局光照理论的引进培养，并开始迅速移动到如何控制基本GI渲染设置。弗雷德展示如何平衡精度，强度和光子发射创建快速，优质的产品呈现使用全局光照沿着决赛聚集。烧碱照明技术和艺术的挑战都覆盖了非常详细。材料，如玻璃，金属光泽和半透明的塑料作为案例研究。合成的地址应为任何照明工作流程的一个组成部分，因为它有助于提高工作效率，同时渲染通行证是任何成功的照明战略的关键。对于那些有兴趣在掌握的mental ray，这个标题提供了从经验丰富的行业艺术家的宝贵技术。

In this lecture, Frederic Durand demonstrates a variety of techniques for using Global Illumination and Caustics within Maya and mental ray. Global Illumination and Caustics
rendering techniques use photons as the method to create natural lighting phenomenon. Photon based lighting allows light rays to bounce and create complex effects that are not possible with other rendering methods. The training begins with an introduction on Global Illumination theory and quickly moves into how to control the basic GI render settings. Fred shows how to balance accuracy, intensity and photon emission to create fast, production quality renders using Global Illumination alongside of Final Gather. The technical and artistic challenges of caustic lighting are covered in great detail. Materials such as glass, shiny metals and translucent plastics are used as case studies. Compositing is addressed as an integral part of any lighting workflow, as it helps to work more efficiently, while rendering in passes is critical to any successful lighting strategy. For those interested in mastering mental ray, this title offers invaluable techniques from an experienced industry artist.
