// .NAME vtkRendererSource - take a renderer into the pipeline
|
|
// .SECTION Description
|
|
// vtkRendererSource is a source object that gets its input from a
|
|
// renderer and converts it to structured points. This can then be
|
|
// used in a visualization pipeline. You must explicitly send a
|
|
// Modify() to this object to get it to reload its data from the
|
|
// renderer. Consider using vtkWindowToImageFilter instead of this
|
|
// class.
|
|
//
|
|
// The data placed into the output is the renderer's image rgb values.
|
|
// Optionally, you can also grab the image depth (e.g., z-buffer) values, and
|
|
// place then into the output (point) field data.
