![]() ![]() Using F8 key, Marking menu with right mouse button, or select icon from the menu. ![]() You need two curves (profile and path) perpendicularly positioned. The quality and type of curve will affect the characteristics of the surface. As with the NURBS curve, it is desirable to define surfaces with the fewest evenly spaced isoparms or CVs. NURBS models, whether they are organic or industrial in nature, are generally made up of several adjoining four-sided patches. NURBS surfaces have CVs, hulls, and spans which define the shape of a four-sided surface. The components of the NURBS surface are very similar to those of the NURBS curve. NURBS, CV (Control Vertex), EP (Edit Point), start of curve, curve direction, Although other 3D programs might have more than one type of spline technology, you should know that even though Maya sometimes drops the word “NURBS,” we are still dealing with this technology whenever we use “curves” and “surfaces” within Maya. >Maya calls any NURBS curve simply a “curve.” In some menus, Maya will refer to a surface created from curves as a “surface” and sometimes as “NURBS,” such as in the 'Modify/Convert' menu. NURBS surface types are widely used in the fields of animation, games, scientific visualization, and industrial design. NURBS are useful for constructing many types of organic 3D forms because of the smooth and minimal nature of the curves they use to construct surfaces. NURBS (Non-Uniform Rational B-Splines) are one geometry type you can use to create 3D curves and surfaces in Maya. NURBS are commonly used in computer-aided design (CAD), manufacturing (CAM), and engineering (CAE) and are part of numerous industry-wide standards. ![]() It offers good flexibility and precision for handling both analytic (surfaces defined by common mathematical formulas) and modeled shapes. **Non-uniform rational basis spline (NURBS)** is a mathematical model commonly used in computer graphics for generating and representing **curves** and **surfaces**. Using one of several geometry types, 3D artists can build surfaces, then push and pull points to change their shape. Being able to create NURBS geometry and to modify its properties.
