About Texturing Polygons

All of the techniques covered thus far work on polygon primitives. They will not, however, necessarily work on any polygon surfaces you’ve modeled. While NURBS surfaces are always four-sided, polygon surfaces are made up of many small faces—which means that applying textures to them is not as simple as it is on NURBS surfaces.

Think of a wrapped present. Imagine carefully removing the wrapping paper and flattening it out. Once the paper has been flattened, you can easily paint a new image on it (Figure 14.71).
