// CLASS DESCRIPTION (MFnDagNode)
|
||||
//
|
||||
// The MFnDagNode function set is used to query and set the attributes of
|
||||
// nodes in the DAG (Directed Acyclic Graph). The DAG is a graph that
|
||||
// describes the hierarchy of the objects in the model. At each level of
|
||||
// the hierarchy there is a four by four transformation matrix that
|
||||
// affects all of the objects beneath it in the DAG.
|
||||
//
|
||||
// In the DAG, geometry objects (also known as shapes) do not have
|
||||
// transformation information associated with them. Only transform
|
||||
// nodes have actual transform matrices (see MFnTransform).
|
||||
//
|
||||
// Each node that exists in the DAG is also a dependency node that
|
||||
// exists in the dependency graph. This makes it possible to control
|
||||
// the attributes of a DAG node based on calculations performed by
|
||||
// dependency nodes.
|
||||
//
|
||||
// There are two ways to specify a DAG node in Maya. The first is
|
||||
// to use an MObject handle, which acts as a pointer to a specific
|
||||
// node in the DAG. Given only an MObject, it is not possible to do
|
||||
// world space operations on a DAG node because there may be more
|
||||
// than one path through the DAG to any given node. In other words,
|
||||
// it is not possible to identify a particular instance only given
|
||||
// an MObject.
|
||||
//
|
||||
// In many cases it is preferable to use a DAG path (MDagPath) to specify
|
||||
// a DAG node. A DAG path always refers to a specific instance of an
|
||||
// object. This makes it possible to perform unambiguous world space
|
||||
// transformations.
|
||||
//
|
||||
// It is also possible to iterate over the nodes in the DAG using a
|
||||
// DAG iterator (MItDag).
