In this lesson you were
introduced to a few basic techniques related to NURBS modeling:
- Revolving a curve is the easiest way
to create surfaces with radially symmetrical forms— wheels,
vases, glasses, pillars, and so on.
- NURBS surfaces are webs of interconnected
curves. The creation curves are used to create and subsequently
modify the surfaces if required.
- Proficiency at drawing and editing curves
is an important part of NURBS modeling.
- The grid is a useful aid for constructing
and modifying curves.
Some additional points
you should know are:
- You cannot render curves, so your work
with them is always an adjunct to creating and editing surfaces.
- Besides moving a curve’s CVs to alter
its shape, you can cut, attach, extend, close, and smooth curves.
- After you create a surface from a revolved
curve, you can edit the surface at a component level by moving CVs
or scaling groups of CVs on that surface to customize the shape
of the surface. (You will need to turn off construction history
in order to do this.)
