Fig. 10.35 The seam at the top of this pedestal can be pie-cut or cut all the way around its
circumference
Fig. 10.36 Depending on the resolution of the map used for this object, it is likely that some of the
smaller polygons will have zero map area
The amount of pixels covered in UV space is dependent on the resolution of the
texture map. If a texture map has only four pixels in a checkerboard pattern, then
any polygon that was located within any one of the four quadrants of UV space
