## Detailed Description

create hierarchies of props

vtkPropAssembly is an object that groups props and other prop assemblies into a tree-like hierarchy. The props can then be treated as a group (e.g., turning visibility on and off).

A vtkPropAssembly object can be used in place of an vtkProp since it is a subclass of vtkProp. The difference is that vtkPropAssembly maintains a list of other prop and prop assembly instances (its "parts") that form the assembly. Note that this process is recursive: you can create groups consisting of prop assemblies to arbitrary depth.

vtkPropAssembly's and vtkProp's that compose a prop assembly need not be added to a renderer's list of props, as long as the parent assembly is in the prop list. This is because they are automatically rendered during the hierarchical traversal process.

Warning
  vtkPropAssemblies can consist of hierarchies of assemblies, where one actor or assembly used in one hierarchy is also used in other hierarchies. However, make that there are no cycles (e.g., parent->child->parent), this will cause program failure.

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.

## ◆ RenderOpaqueGeometry()

int vtkPropAssembly::RenderOpaqueGeometry | ( | vtkViewport * | ren | ) |

The rendering process is recursive. The parts of each assembly are rendered only if the visibility for the prop is turned on.

Reimplemented from vtkProp.

## ◆ GetBounds()

double* vtkPropAssembly::GetBounds | ( |  | ) |
| overridevirtual

Get the bounds for this prop assembly as (Xmin,Xmax,Ymin,Ymax,Zmin,Zmax).

May return NULL in some cases (meaning the bounds is undefined).

## ◆ InitPathTraversal()

void vtkPropAssembly::InitPathTraversal | ( |  | ) |
| overridevirtual

Methods to traverse the paths (i.e., leaf nodes) of a prop assembly.

These methods should be contrasted to those that traverse the list of parts using GetParts(). GetParts() returns a list of children of this assembly, not necessarily the leaf nodes of the assembly. To use the methods below - first invoke InitPathTraversal() followed by repeated calls to GetNextPath(). GetNextPath() returns a NULL pointer when the list is exhausted. (See the superclass vtkProp for more information about paths.)

Reimplemented from vtkProp.

## ◆ GetNextPath()

vtkAssemblyPath* vtkPropAssembly::GetNextPath | ( |  | ) |

Methods to traverse the paths (i.e., leaf nodes) of a prop assembly.

These methods should be contrasted to those that traverse the list of parts using GetParts(). GetParts() returns a list of children of this assembly, not necessarily the leaf nodes of the assembly. To use the methods below - first invoke InitPathTraversal() followed by repeated calls to GetNextPath(). GetNextPath() returns a NULL pointer when the list is exhausted.

## ◆ GetNumberOfPaths()

int vtkPropAssembly::GetNumberOfPaths | ( |  | ) |
| overridevirtual

Methods to traverse the paths (i.e., leaf nodes) of a prop assembly.

These methods should be contrasted to those that traverse the list of parts using GetParts(). GetParts() returns a list of children of this assembly, not necessarily the leaf nodes of the assembly. To use the methods below - first invoke InitPathTraversal() followed by repeated calls to GetNextPath(). GetNextPath() returns a NULL pointer when the list is exhausted.
