Hi All,
I am just modifying this example (
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/CurvedReformation).
At this portion of this example,
// Create a mapper and actor.
vtkSmartPointer<vtkDataSetMapper> mapper =
vtkSmartPointer<vtkDataSetMapper>::New();
mapper->SetInputConnection(sampleVolume->GetOutputPort());
and this statement in function SetInputConnection:
*sampleVolume->GetOutputPort()*, is giving me values on the surface.
My Query:
I have to use these values and using this values i have to generate a 2D image.
could you please suggest me some class or the way(method), by which i
can achieve this task. it`s really very urgent for me, please help.
Looking forward your reply.
