<P>Hi all,</P>
<P> I've successfully finished the Probing,
with unstructured grid format as the source and image data format
as the input. The unstructured grid data includes some
points, triangles quadrangles and so on. However, if I set the
unstructured grid data which has only points,with no cells like triangles
or quadrangles, it also can be done successfully,but the attribute value of
all interplated points on the image data are all zero. So I wonder about
it:</P>
<P>1) What's wrong with the data? We can only use unstructured grid format
with cells?<BR>2) Is there any other data format that can be the source
data of the vtkProbeFilter?</P>
<P>Thanks.</P>
