the SetScalarModeToUseCellData method exists in the 4.4 release of
VTK. At the time, only point data was supported (and if I recall you could
only use the active scalars). The CVS trunk has this method and the
ability to render cell data.</FONT></SPAN></DIV>

the method is SetRayCastFunction, not SetVolumeRayCastFunction. However,
there is no reason to call this since a default
vtkUnstructuredGridBunykRayCastFunction is created for you and that is the only
concrete implementation of vtkUnstructuredGridVolumeRayCastFunction
available.</FONT></SPAN></DIV>

<DIV>No one responded to my last email. Now I cut my qestion short. Here are a
few errors I got</DIV>
<DIV>while compiling my program:</DIV>
<DIV> </DIV>
<DIV>E2316: SetScalarModeToUseCellData() is not a member of </DIV>
<DIV> vtkUnstructuredGridVolumeRayCastMapper<BR>E2316:
SetVolumeRayCastFunction() is not a member of </DIV>
<DIV> vtkUnstructuredGridVolumeRayCastMapper</DIV>
<DIV> </DIV>
<DIV>There is no example or test about how to use
vtkUnstructuredGridBunykRayCastFunction.</DIV>
<DIV>IntermixedUnstructuredGrid.tcl did not use any raycast function either.
Any comments</DIV>
<DIV>about this? I am using VTK4.4 on WinXP.</DIV>
<DIV> </DIV>
<DIV>Will someone please tell me what's wrong? Thanks a bunch.</DIV>
