Detailed Description

create hierarchies of vtkProp3Ds (transformable props)

vtkAssembly is an object that groups vtkProp3Ds, its subclasses, and other assemblies into a tree-like hierarchy. The vtkProp3Ds and assemblies can then be transformed together by transforming just the root assembly of the hierarchy.

A vtkAssembly object can be used in place of an vtkProp3D since it is a subclass of vtkProp3D. The difference is that vtkAssembly maintains a list of vtkProp3D instances (its "parts") that form the assembly. Then, any operation that transforms (i.e., scales, rotates, translates) the parent assembly will transform all its parts. Note that this process is recursive: you can create groups consisting of assemblies and/or vtkProp3Ds to arbitrary depth.

To add an assembly to the renderer's list of props, you only need to add the root of the assembly. During rendering, the parts of the assembly are rendered during a hierarchical traversal process.

Warning
Collections of assemblies are slower to render than an equivalent list of actors. This is because to support arbitrary nesting of assemblies, the state of the assemblies (i.e., transformation matrices) must be propagated through the assembly hierarchy.
Assemblies 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.
If you wish to create assemblies without any transformation (using the assembly strictly as a grouping mechanism), then you may wish to consider using vtkPropAssembly.

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.

◆ AddPart()

void vtkAssembly::AddPart ( vtkProp3D )

Add a part to the list of parts.

◆ RemovePart()

void vtkAssembly::RemovePart ( vtkProp3D )

Remove a part from the list of parts,.

◆ GetParts()

vtkProp3DCollection* vtkAssembly::GetParts ( )
inline

Return the parts (direct descendants) of this assembly.

Definition at line 90 of file vtkAssembly.h.

◆ GetActors()

void vtkAssembly::GetActors ( vtkPropCollection )
overridevirtual

For some exporters and other other operations we must be able to collect all the actors or volumes.

These methods are used in that process.

Reimplemented from vtkProp.

◆ GetVolumes()

void vtkAssembly::GetVolumes ( vtkPropCollection )
overridevirtual

Reimplemented from vtkProp.

◆ RenderOpaqueGeometry()

int vtkAssembly::RenderOpaqueGeometry ( vtkViewport ren)
overridevirtual

Render this assembly and all its parts.

The rendering process is recursive. Note that a mapper need not be defined. If not defined, then no geometry will be drawn for this assembly. This allows you to create "logical" assemblies; that is, assemblies that only serve to group and transform its parts.

Reimplemented from vtkProp.

vtkTypeBool vtkAssembly::HasTranslucentPolygonalGeometry ( )
overridevirtual

Does this prop have some translucent polygonal geometry?

Reimplemented from vtkProp.

◆ ReleaseGraphicsResources()

void vtkAssembly::ReleaseGraphicsResources ( vtkWindow )
overridevirtual

Release any graphics resources that are being consumed by this actor.

The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkProp.

◆ InitPathTraversal()

void vtkAssembly::InitPathTraversal ( )
overridevirtual

Methods to traverse the parts of an assembly.

Each part (starting from the root) will appear properly transformed and with the correct properties (depending upon the ApplyProperty and ApplyTransform ivars). Note that the part appears as an instance of vtkProp. 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 with the correct transformation or properties. To use the methods below - first invoke InitPathTraversal() followed by repeated calls to GetNextPath(). GetNextPath() returns a NULL pointer when the list is exhausted.
