way it was printed: unwrapped and flattened out. As with subdivision surfaces, UVs are a subject for another
chapter.
The final sets of fields (labeled Min X, Y, and Z and Max X, Y, and Z) give you another way to indicatethe
size and position of the object. If you know the starting and ending boundaries for the object, these can be
entered here. If the size and position have already been set in the Size and Position fields, the Min and Max
fields will automatically be filled.
The Sphere Tool
The Sphere too l basics are much like those of the Cube tool, as you can see in Figure 2-6 . Note that the
second field denotes radius (not diameter), so entering 500 mm in these fields will result in a sphere that
is the same size as a cube with 1 m in each dimension. Sides and Segments will divide the geometry much
like the segments on the cube, but they are in relation to the poles of the sphere (in the default Globe mode).
Sides are the radial divisions (longitude), and segments make up the concentric divisions (latitude). The
Axis defines the direction that the poles face.
Figure 2-6: Sphere tool options
Unlike the Cube tool, the Sphere tool has several modes: Globe, Quadball, and Tesselation. These sphere
types are illustrated in Figure 2-7 . The Globe mode works as previously discussed and represents a typical
