Advantages And Disadvantages Of Maya Software Requirements
NURBS is an acronym that stands for Non-Uniform Rational B-Spline. As a modeler, you need to understand a few concepts when working with NURBS, but the software takes care of most of the advanced mathematics so that you can concentrate on the process of modeling.
Early in the history of 3D computer graphics, NURBS were used to create organic surfaces and even characters. However, as computers have become more powerful and the software has developed more advanced tools, most character modeling is accomplished using polygons and subdivision surfaces. NURBS are more ideally suited to hard-surface modeling; objects such as vehicles, equipment, and commercial product designs benefit from the types of smooth surfacing produced by NURBS models.
There are several advantages and disadvantages for both. Maya Software's primary advantage is speed, while mental ray has more features and can output. Review the advantages and the limitations of surface modeling and working with polygons. Advantages and Limitations of Surface Modeling. That the model can be displayed within a game or software application. In most cases, the tessellation process is hidden from the 3D artist so.
All NURBS objects are automatically converted to triangles at render time by the software. You can determine how the surfaces will be tessellated (converted into triangles) before rendering, and you can change these settings at any time to optimize rendering. This gives NURBS the advantage that their resolution can be changed when rendering. Models that appear close to the camera can have higher tessellation settings than those farther away from the camera.

One of the downsides of NURBS is that the surfaces themselves are made of four-sided patches. You cannot create a three- or five-sided NURBS patch, which can sometimes limit the kinds of shapes that you can make with NURBS. If you create a NURBS sphere and use the Move tool to pull apart the control vertices at the top of the sphere, you'll see that even the patches of the sphere that appear as triangles are actually four-sided panels .
