public class Scale
A Scale
node scales the local coordinate system
using the scaling factors scaleX
,
scaleY
and scaleZ
. In general, the
scaling factors may differ. However, there is the
constructor Scale(float)
which initializes
the three factors with the same value such that
a uniform scaling is performed.
This class declares two predicates:
Scale.Pattern
allows one to write
Scale(x,y,z)
in a pattern of an XL query.
Scale.XPattern
is useful for uniform
Scale
nodes since it allows one to write
Scale(x)
in a pattern. It uses
scaleX
to obtain the value for the
predicate argument.
