Lesson 2: Sculpting a NURBS surface
Introduction
In addition to creating NURBS surfaces using curves, you can edit and sculpt
surfaces and primitive objects in Maya using the Sculpt Geometry Tool.
The Sculpt Geometry Tool allows you to interactively push or pull on the
surface regions to create areas that are embossed or in relief in relation to the
surface.
In this lesson, you learn some of the basic concepts of these tools by sculpting
a cartoon face and head from a NURBS primitive sphere using the Sculpt
Geometry Tool.
In this lesson you learn:
Basic sculpting operations (push, pull, smooth, relax and erase) with the
Sculpt Geometry Tool.
How the density of isoparametric lines affects the surface detail possible
when sculpting.
How to increase the surface subdivisions on a NURBS surface to aid with
surface sculpting.
How to change the brush radius for the Sculpt Geometry Tool.
How Opacity and Max Displacement affect the sculpting operations.
How to import geometry from a pre-existing file into your current scene.
