本教程是由cmiVFX机构出品的HOUDINI中摄像机映射技术教程，教程使用软件：Houdini，MP4视频格式，作者：Alvaro Castaneda，语言：英语。
摄像机映射技术在特效行业应用的非常普遍。不论是使用它3D图像转换为3D，还是使用多个摄像机映射来建模一个细致的点云用于分析或者是测量运算。人们已经发现使用摄像机映射技术是将复杂的真实效果在镜头中制作出来的最简单的方法了。
Houdini 是一个特效方面非常强大的软件。许多电影特效都是由它完成：指环王中“甘道夫”放的那些“魔法礼花”，还有“水马”冲垮“戒灵”的场面，后天中的龙卷风等等，a52的汽车广告，反正只要是涉及DD公司制作的好莱坞一线大片，几乎都会有Houdini参与和应用。
Houdini不光只适用于视觉特效的制作，随着HOUDINI适用于各种平台，并且出现了很多的HOUDINI培训教学，HOUDINI开始进入了动态图像设计领域。因为其自身的流程化特性，加上其强大的动力学系统，让HOUDINI在数据可视化方面占有一席重要的地位，让图形设计师能够通过它表达自己的观点。
A voice in the dark background emanates a whisper by saying softly, "They say it couldn't be done." BAMM! Another HOT one for HOUDINI by CMIVFX! Where you really expecting something else? Of course not. but enough of the chatter, let's get down to Earth and talk about what we have for you today. One of the most efficient ways to get complex looking CG is rarely CG at all. The use of projections are used in all aspects of the Visual Effects industry. Whether its taking 2D and turning it into Stereoscopic, or simply using multiple camera projections for modeling a detailed point cloud for analysis and measurement calculations in a digital set, the world has found that using photographic camera projections are the best way to get complex looking realism into a shot with the least amount of effort. The amount of detail that goes into camera projection modeling is up to the end users requirements for a shot. In some cases, highly detailed geometry can be created using several images so that simulations can be calculated on the resulting geometry's surface. In this brand new video from cmiVFX, you will learn from scratch, how to start using camera projections in Houdini to better enrich your projects today. Now with version 12 of Houdini, the ability to utilize the openGL view for super fast rendering of projection building has never been as useful as it is today. Find out how to make the best of projections today with our in-house Houdini Genius, VAROMIX. By the end of this ride, you will be building yourself a new and improved demo reel section in a jiffy!!
