Orientation
Orientation is the steering system in ZBrush. Often you aren’t even aware of it, and that’s
the way it should be. We don’t think about the steering column once we are in our car.
We just put the key in and go.
Sometimes, though, we need to take full control of our steering wheel and we do this
in the Picker palette. The three buttons that we are concerned about in the Picker palette
are as follows:
Once Ori•
Cont Ori•
Select Orientation•
To understand what these features do, we should back up a bit and return to the sphere
of influence from the Depth section. When you click on the surface of the model, ZBrush
samples the polygons within its sphere of influence. It then determines the orientation of
that sphere by averaging out the surface normal within its sampled radius. However, the
job is not done there. ZBrush has a choice. It can either continually resample the orienta-
tion or lock it down and drag that through your model. Figure 1.17 illustrates the effect
of each option.
