Chapter 3: Modeling I > The Bottom Line

The Bottom Line

Understand polygon geometry. Polygon geometry consists of flat faces connected and shaped to form three-dimensional objects. You can edit the geometry by transforming the vertices, edges, and faces that make up the surface of the model.

Master It Examine the polygon primitives in the Create images Polygon Primitives menu.

Understand subdivision surfaces. Most subD models start out as polygons and are converted to subDs only toward the end of the modeling process.

Master It Convert a polygon model to a subdivision surface model. Examine how the polygon object changes in shape.

Understand NURBS surfaces. NURBS surfaces can be created by lofting a surface across a series of curves. The curve and surface degree and parameterization affect the shape of the resulting surface.
