TSplines 1.5b for maya 7.0 (MAYA建模插件)
解压码:www.cgtime.org

T-Splines是由Alias公司领导开发的一种具有革命性的崭新建模技术,它结合了Nurbs和细分表面建模技术的特点,虽然和Nurbs很相似,不过它极大地减少了模型表面上的控制点数目,可以进行局部细分和合并两个Nurbs面片等操作.使你的建模操作速度和渲染速度都得到提升.T-Splines在SIGGRAPH 2005大会上也进行了展示,其T-Splines for maya插件也将在不久后发售.

T-Splines 作为一种新的 surface 的表示方式,最初是在 2003 年和 2004 年的 Siggraph papers 会议上首次公开的。 T-Splines 是 NURBS 和 SubDs 的扩展,并且可以从它们其中的任何一个无损的转换过来,就像是 polymeshes 。 T-Splines 也可以进行 T-Junctions ,这可以让你不用创建‘ n-gons '就可以在 T 中停止 isoparms/edgeloops 。也就是说,这个新的 surface 依然可以像 quad 那样 shades 和 deforms ,而不需要额外的几何体。

T-Splines allows you to keep the control points that are essential and eliminate those that are not.
 

 
Using the T-Splines Maya Plugin

The T-Splines Maya Plugin Version 1 was designed to accommodate two basic workflows: using T-Splines to create a new model and converting existing models to T-Splines for simplification.

1. Using T-Splines when creating a new model
There are a number of ways to take advantage of T-Splines when creating a new model. Since the main advantage of T-Splines is in editing and detail work, many artists create the general shape of their model with polygons, then convert to T-Splines to add detail and make changes. It is also possible to begin modeling directly in T-Spline primitives.

2. Using T-Splines to simplify and merge existing models
As 3d models become more and more realistic, every industry is demanding more high-detailed models. Achieving this level of detail in NURBS or polygons can result in heavy models that are unwieldy to edit and expensive to render. By converting existing NURBS and polygon models to T-Splines, you can subsequently cleanse the model of unneeded data and merge multiple-patch NURBS models into a single surface. This results in a T-Spline model that is easy to animate and edit, and accommodates arbitrary areas of high detail while leaving less detailed areas of the surface uncluttered with control points.
