<DIV>I'm employing vtkImageReslice to do reslice. But vtkRenderWindow consistently hide part or the whole result image. </DIV>
<DIV>I guess it might be caused by axis rotation. </DIV>
<DIV> </DIV>
<DIV>1. How can I ask vtkRenderWindow to show the whole result to me?</DIV>
<DIV>2. How can I know the slice range. mapper->GetWholeZMax()/GetWholeZMin() just return the originial data source Z range.</DIV>
<DIV>3. How to use interaction tool to pick a point and know its originial x,y,z value.</DIV>
<DIV> </DIV>
<DIV>The screenshot and test code are attached.</DIV>
<DIV> </DIV>
<DIV>I read through VTK User's Guide and googled a lot, but did not get anything helpful.</DIV>
<DIV> </DIV>
<DIV>Any discussion/suggestion is welcome!</DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>
