Detailed Description

represent a node in an assembly

vtkAssemblyNode represents a node in an assembly. It is used by vtkAssemblyPath to create hierarchical assemblies of props. The props can be either 2D or 3D.

An assembly node refers to a vtkProp, and possibly a vtkMatrix4x4. Nodes are used by vtkAssemblyPath to build fully evaluated path (matrices are concatenated through the path) that is used by picking and other operations involving assemblies.

Warning

The assembly node is guaranteed to contain a reference to an instance of vtkMatrix4x4 if the prop referred to by the node is of type vtkProp3D (or subclass). The matrix is evaluated through the assembly path, so the assembly node's matrix is a function of its location in the vtkAssemblyPath.

vtkAssemblyNode does not reference count its association with vtkProp. Therefore, do not create an assembly node, associate a prop with it, delete the prop, and then try to dereference the prop. The program will break! (Reason: vtkAssemblyPath (which uses vtkAssemblyNode) create self-referencing loops that destroy reference counting.)

Member Function Documentation

static vtkAssemblyNode* vtkAssemblyNode::New ( )

static

Create an assembly node.

static int vtkAssemblyNode::IsTypeOf ( const char *  type )

static

virtual int vtkAssemblyNode::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObject.

static vtkAssemblyNode* vtkAssemblyNode::SafeDownCast ( vtkObjectBase *  o )

static

virtual vtkObjectBase* vtkAssemblyNode::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkObject.

vtkAssemblyNode* vtkAssemblyNode::NewInstance

(

)

const

void vtkAssemblyNode::PrintSelf ( ostream &  os, vtkIndent  indent  )

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

virtual void vtkAssemblyNode::SetViewProp ( vtkProp *  prop )

virtual

Set/Get the prop that this assembly node refers to.

virtual vtkProp* vtkAssemblyNode::GetViewProp ( )

virtual

Set/Get the prop that this assembly node refers to.

void vtkAssemblyNode::SetMatrix

(

vtkMatrix4x4 *

matrix

)

Specify a transformation matrix associated with the prop. Note: if the prop is not a type of vtkProp3D, then the transformation matrix is ignored (and expected to be NULL). Also, internal to this object the matrix is copied because the matrix is used for computation by vtkAssemblyPath.

virtual vtkMatrix4x4* vtkAssemblyNode::GetMatrix ( )

virtual

Specify a transformation matrix associated with the prop. Note: if the prop is not a type of vtkProp3D, then the transformation matrix is ignored (and expected to be NULL). Also, internal to this object the matrix is copied because the matrix is used for computation by vtkAssemblyPath.

virtual unsigned long vtkAssemblyNode::GetMTime ( )

virtual

Override the standard GetMTime() to check for the modified times of the prop and matrix.

Reimplemented from vtkObject.
