Hello, <br><br> I am fairly new to VTK and am going through the
Visualizing Toolkit 4th edition text and am hitting a problem in one of
the examples. When I go to make the pipeline to connect the data with
the hedgehog function, I do not know what command to use. In the
example, they use HedgeHog->SetInputData(SGrid), where HedgeHog and
Grid are classes definded by the user, but HedgeHog does not have a
member called SetInputData...I have check the doxygen page and in my
vtkpython wrapping. Does anyone know how to connect this pipeline then?
Here is the code I have written for it...the line of interest lies one
paragraph after the end of the nested for loops. Please no laughing at my code, I am also new to C++ object oriented programming as well.<br></blockquote><div><br></div><div>Are you looking at this page:</div><div><a href="http://www.vtk.org/doc/nightly/html/classvtkHedgeHog.html">http://www.vtk.org/doc/nightly/html/classvtkHedgeHog.html</a></div>

<div><br></div><div>which has the function you're looking for. (They are functions of a parent class).</div><div><br></div>Please see this example:<div><a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/HedgeHog">http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/HedgeHog</a></div>
<div><br></div><div>The VTK6 way to do it is SetInputData, and the VTK5 way to do it is just SetInput. Both are demonstrated.</div><div><br>Also note the use of vtkSmartPointer - this will let you avoid the giant list of Delete() calls at the end of the program.</div>
