TABLE OF CONTENTS The UVW Map modifier you added in the last exercise told VIZ the size, location, and orientation of the material on the object it is assigned to. At render time, the image is usually applied to the object in a repeated, or tiled, fashion. You can also set a material to apply the bitmap just once. In this section, you'll take a closer look at the UVW Map modifier.
The UVW Map gizmo you saw in the last exercise is a visual representation of the mapping coordinates. Its shape and color are aids in helping you see the bitmap's orientation more clearly. As mentioned earlier, the small line at the top of the icon represents the top of the bitmap, while the green shows the right side. These indicators can tell you at a glance whether the bitmap image of the material you are using is upside down, mirrored, or backward in relation to the object to which the coordinates are being applied, as shown in Figure 7.18.
The orientation of the bitmap in the preceding exercise is really not that important, but it can be important for texture maps that do have a specific orientation such as a brick pattern, or a single image such as a wine label or a road sign.
Figure 7.19 shows the UVW...
