// Description : An animation channel that accepts a matrix each frame
|
|
// from some dynamic input provided by code.
|
|
//
|
|
// This object operates in two modes: in explicit mode,
|
|
// the programmer should call set_value() each frame to
|
|
// indicate the new value; in implicit mode, the
|
|
// programmer should call set_value_node() to indicate
|
|
// the node whose transform will be copied to the joint
|
|
// each frame.
