<DIV><FONT size=2 face=Verdana>I write a filter class just like the
vtkAppendFilter ,and change a little on the mothod <STRONG>RequestData</STRONG>
..My class also inherited from vtkUnstructuredGridAlgorithm .I did the
job all on windows vs2008.</FONT>The vtkAppendFilter.h defines the class
with VTK_GRAPHICS_EXPORT which means __declspec( dllimport ) on my
computer,but if I used that macro to define my own filter class it would met
some link errors .If I use the macro VTK_EXPORT or did not use
macro to define my filter class ,it can complie well,but it did not
work.I tried the debug.I found it would not invoke my RequestData function at
all,and the it would not invoke
vtkUnstructuredGridAlgorithm'RequestData methord either.The program invoked
the method RequestData form vtkAlgorithm class directly.I don't know why?
what should I do if want to define my own filter? Thanks a lot!</DIV>
