vtkAssemblyNode Class Reference
#include <vtkAssemblyNode.h>
Detailed Description
represent a node in an assemblyvtkAssemblyNode 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.
Reimplemented from vtkObject.
| virtual const char* vtkAssemblyNode::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkObject.
| static int vtkAssemblyNode::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkObject.
| 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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkObject.
| static vtkAssemblyNode* vtkAssemblyNode::SafeDownCast | ( | vtkObject * | o | ) | [static] |
Reimplemented from vtkObject.
| void vtkAssemblyNode::PrintSelf | ( | ostream & | os, | |
| vtkIndent | indent | |||
| ) | [virtual] |
| 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.
| virtual void vtkAssemblyNode::SetProp | ( | vtkProp * | prop | ) | [virtual] |
