<P><FONT SIZE=2 FACE="Arial">Hi vtkusers,</FONT>

<P><FONT SIZE=2 FACE="Arial">I have a volume data set, that is, a vtkPolyData with (x, y, z, scalar). Now I have to convert this data set into vtkImageData for volume rendering. One way to go is to use vtkProbeFilter.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">In VTK/Examples/Annotation/Tcl/xyPlot.tcl, vtkLineSource is used to sample a vtkPolyData along a line.</FONT>

<P><FONT SIZE=2 FACE="Arial">In VTK/Examples/VolumeRendering/Tcl/volSimpleLOD.tcl, vtkPlaneSource is used to sample a vtkPolyData on a plane.</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">To resample a volume data for a vtkImageData, should I use vtkCubeSource instead? I found that vtkCubeSource has no method to SetResolution(x, y, z) to determine the sample intervals. The above two examples lead to the output of vtkPolyData with the help of</FONT> <FONT FACE="Times New Roman">vtkTransformPolyDataFilter. How do I get a vtkImageData by probing? Do I have to probe one plane at a time and assemble vtkImageData manually.</FONT></P>
