Surface, or when you create an individual point
sub-object. Points that are part of a Point Curve or
Point Surface are constrained to lie on the curve
or surface.
Points behave somewhat like vertices for
spline
objects (page 1–261)
,buttheirbehaviorisnot
ident ical and they are a distinc t object type.
Helper
object points (page 2–22)
are also a distinct object
type. You can’t use spline vertices or helper points
as NURBS points (though you can convert a spline
to a NURBS curve).
Point Curv e
NURBS point curve
A curve defined by points. The points are
constrained to lie on the curve. (Or you can
think of the curve as being dependent on its point
locations.) More than one NURBS solution is
possible for a Point Curve; occasionally this can
cause unexpected results.
Poi nt Surfa ce
NURBS point sur f ace
A surface defined by points. The points are
constrained to lie on the surface. (Or you can
think of the surface as being dependent on its
point locations.) More than one NURBS solution
is possible for a Point Surface; occasionally this can
cause unexpected results.
Pos es
When you work with a biped (page 2–701) ,the
pose is the stance of the entire biped. You can copy
and paste poses. See
Copy/Paste Rollout (page
2–818)
.
Pos it i on al M a rker s
In a motion-capture s ession, positional markers
are reflective objects placed on the “actor” or
“talent.” The markers enable motion-capture
hardware to record the position of various parts of
the talent’s body while performing motions.
Pos tu r e
When you work with a biped (page 2–701) ,
the posture refers to the position of selected
