This operator builds a general 4×4 transform matrix from a set of input parameters
that match the attributes and priorities used in Copy and Instancing
operations . Those inputs that can take precedence over others
will also have a corresponding
use input to signify their value should be used.
For example, create a Parameter VOP bound to the
orient attribute, plug its output into the
orient input of this VOP, and plug its
bound_orient output into the
useorient input. The VOP will use the value from the
orient parameter when it is
bound to an attribute on the geometry, but use lower precedence attributes like
v if no such attribute exists.
