浅谈maya建模--三维坐标变换.docx

计算机高级图形学浅谈Maya的建模中的坐标变换浅谈Maya的建模中的坐标变换[摘要]Maya是世界上目前最为优秀的三维软件制作软件之一，所谓三维，就是3D，3D中的D就是Dimensional的缩写，三维模型中点的位置由三个坐标决定，客观存在的现实空间就是三维空间，具有长、宽、高三种度量。三维其实是相对于二维来说的，因其采用了立体空间的概念，所以显得更加真实，而且对空间操作的随意性也增强了，看起来更丰富！在动画制作过程中，模型起着至关重要的作用，一个好的模型不一定会有好的作品，但是一个好的作品一定有一个好的模型。只有开始的模型建的好，才能让后续的工作更加顺利和轻松的完成。本文涉及的内容有三种建模方式，分别是多边形建模，曲面建模和细分建模。三维模型的制作不单单是要求模型的外形要美观、合理，更要求模型的布线、结构要准确。而坐标变换让我们的建模更加精确、快捷。关键词：Maya；功能；渲染；建模；变换Brief discussion the modeling of Maya on transformation of coordinates[Abstract] Maya is currently the worlds most outstanding one of the three dimensional animation production. Three dimension is 3D, D of the 3D is the abbreviation of dimension, the position of point is determined by three coordinates in 3D modeling. Objective reality space is three-dimensional space, has the length, width, three kinds of measure. Three-dimensional is relative to two-dimensional, because its adopted the concept of stereo space, so more real, but also to the arbitrary spatial operation, looks more colorful. In the process of animation, model is participate in a critical role. A good model doesnt mean a good work, but a good work there must be a good model. Only the beginning model is created meticulous, can the follow-up work finished smoothly and easily. What this text refers to is polygon modeling, surface modeling and subdivision modeling. What the production of 3D modeling requires not only beautiful and reasonable appearance of model, more requirements of the wiring, the structure model is accurate. What’s more, transforming of coordinates make our modeling more accurately and rapidly.Key words: Maya; function; rendering; modeling; transforming目录一 关于Maya51.1Maya的简介与特征51.2Maya的应用领域61.3Maya和3dmax的区别7二 场景的三维表现92.1 场景建模92.2 模型的材质122.3 灯光的渲染15三 模型的坐标变换183.1 二维变换183.2三维变换23学习心得体会26参考文献27一 关于MayaMaya的简介与特征Maya是Alias|Wavefront(2003年7月更名为Alias)公司的产品，作为三维动画软件的后起之秀，深受业界欢迎和钟爱。Maya集成了Alias|Wavefront最先进的动画及数字效果技术，它不仅包括一般三维和视觉效果制作的功能，而且还结合了最先进的建模、数字化布料模拟、毛发渲染和运动匹配技术。MAYA因其强大的功能在3D动画界造成巨大的影响，已经渗入到电影
