Chapter 10. Compound Objects > Lofting Objects

Lofting Objects

Lofting is an incredibly versatile means of modeling and animating 3D forms. The term lofting comes from early methods of shipbuilding in which the hull of a ship was constructed from a series of cross-sections, or ribs, placed along its length. A structure called a loft supported the hull while the ribs were hoisted into place. The process of hoisting the ribs into the loft gave rise to the term lofting.

As in the shipbuilding days of yore, lofting creates a 3D object by placing cross-section shapes along a path. But instead of hoisting wooden ribs into a hull, lofting places shapes along a spline path. As each shape is added to the path, the loft builds a surface, or skin, to accommodate the different outlines of each (Figure 10.37).
