6.7 Texture Mapping
Texture mapping can dramatically alter the surface characteristics of an object.
It adds vitality to models and can provide great visual cues for even simple
models. For example, if we map a woodgrain image to a model of a chair, the
chair will look like it is made out of fine wood grain. Texture mapping an image
of a brick wall onto a single polygon would give the impression that the polygon
had been modeled with many individual bricks, as shown in Fig.6.26.
