away all the curves to help you see the underlying form and structure. One important part of
making sculptures that feel and look natural is to retain the basic structural form of each part
of the figure. This is best accomplished by understanding how to reduce objects into their basic
shapes. Figure 2.19 shows a human figure with one kind of planar analysis applied.Figure 2.19 This human figure is reduced to basic planes to help you
understand the forms.Figure 2.20 shows the basic head form sculpted with ZBrush standard sculpting tools
as well as the same form sharpened and planed with the Polish, Trim, and Clip brushes.
While we work on the head in this section, I will point out some of the kinds of basic
planes. A valuable exercise is to re-create a basic planed version of a head or even a full human
body. This helps you grasp the most fundamental form of the shapes you are trying to create.
See my book ZBrush Digital Sculpting Human Anatomy (Sybex, 2010) for a tutorial on sculpt-
ing a planed human body.Figure 2.20 Head planar analysis
