|
* vtkSingleVTPExporter is a concrete subclass of vtkExporter that writes

|
* a .vtp file and a .png file containing the polydata and texture
|

|
|
* elements of the scene.
|
||
|
|
*
|
||
|
|
* If ActiveRenderer is specified then it exports contents of
|
||
|
|
* ActiveRenderer. Otherwise it exports contents of all renderers.
