Figure 1.11
Polygon models can appear to be solid.
Note
There are solid-modeling programs used in professions such as industrial design, but the calculations
for solid models are more extensive and time consuming than those for wire-frame models.
Textures
are 2D images that are applied to a three-dimensional model to give the
model surface detail. In real life every surface has a texture. Sometimes the textures
are only a color, while other times they might be very complex, such as the bark of
a tree. Take a quick look around and study some of the many textures you see in
everyday life. Figure 1.12 shows the simple polygon head from Figure 1.11 with a
texture added.

A texture is added to the head model.
