// .NAME vtkImporter - importer abstract class
|
|
// .SECTION Description
|
|
// vtkImporter is an abstract class that specifies the protocol for
|
|
// importing actors, cameras, lights and properties into a
|
|
// vtkRenderWindow. The following takes place:
|
|
// 1) Create a RenderWindow and Renderer if none is provided.
|
|
// 2) Call ImportBegin, if ImportBegin returns False, return
|
|
// 3) Call ReadData, which calls:
|
|
// a) Import the Actors
|
|
// b) Import the cameras
|
|
// c) Import the lights
|
|
// d) Import the Properties
|
|
// 7) Call ImportEnd
|
|
//
|
|
// Subclasses optionally implement the ImportActors, ImportCameras,
|
|
// ImportLights and ImportProperties or ReadData methods. An ImportBegin and
|
|
// ImportEnd can optionally be provided to perform Importer-specific
|
|
// initialization and termination. The Read method initiates the import
|
|
// process. If a RenderWindow is provided, its Renderer will contained
|
|
// the imported objects. If the RenderWindow has no Renderer, one is
|
|
// created. If no RenderWindow is provided, both a RenderWindow and
|
|
// Renderer will be created. Both the RenderWindow and Renderer can be
|
|
// accessed using Get methods.
