class TNode: public TNamed, public TAttLine, public TAttFill, public TAtt3D

                    T N O D E  description


    A TNode object is used to build the geometry hierarchy (see TGeometry).
    A node may contain other nodes.

    A geometry node has attributes:
      - name and title
      - pointer to the referenced shape (see TShape).
      - x,y,z offset with respect to the mother node.
      - pointer to the rotation matrix (see TRotMatrix).

    A node can be drawn.

Function documentation

TNode()
 Node default constructor.

 Node normal constructor.

    name    is the name of the node
    title   is title
    shapename is the name of the referenced shape
    x,y,z   are the offsets of the volume with respect to his mother

    title   is title
    shape   is the pointer to the shape definition
    x,y,z   are the offsets of the volume with respect to his mother

 Set the pointer to the parent, keep parents informed about who they have
void SetVisibility(Int_t vis = 1)
 Set visibility for this node and its sons.

  vis = 3  node is drawn and its sons are drawn
  vis = 2  node is not drawn but its sons are drawn
  vis = 1  (default) node is drawn
  vis = 0  node is not drawn
  vis = -1 node is not drawn. Its sons are not drawn
  vis = -2 node is drawn. Its sons are not drawn
  vis = -3 Only node leaves are drawn
  vis = -4 Node is not drawn. Its immediate sons are drawn
void Sizeof3D() const
 Return total size of this 3-D Node with its attributes.
void Streamer(TBuffer& b)
 Stream a class object.
void UpdateMatrix()
