This parameter pulls and pushes on the procession of points making up the curve, depending on how close they are to each weighted vertex, piling up and stretching out accordingly.

One handy trick for flattening your NURBS surface: select every control point, and use the Scale tool to scale everything's Z axis down to zero while leaving everything else as-is using the Adjust Last Operation panel in the bottom left-hand corner.Īside from the placement of each control point, you can also adjust them by Weight-the W field in the vertex's Control Panel settings. NURBS curves created under the Curves dropdown will need to be simplified into a polygon mesh before you'll be able to continue. You can use either as long as you know what you're going for and how both function within the program.Īt this level, the most noticeable distinction will be the difference when you create surface geometry out of a few NURBS objects. Essentially, a NURBS curve becomes a NURBS surface by definition whenever it is extended beyond itself.ĭepending on whether you're using a NURBS curve or surface object, your results may vary.

While both subsets are generated using the same principles, they actually behave very differently within the program-NURBS curves only have one single interpolation axis per point, whereas NURBS surfaces use two, no matter which one you choose.
