<DIV>Hi, vidyadhar:</DIV>
<DIV> </DIV>
<DIV>thanks for helping.</DIV>
<DIV> </DIV>
<DIV>The result I want is like using the the vtkSturcturedGridOutlineFilter to
extract the exact outline of data(any type of shape), when using
vtkOutlineFilter, I can only get a cuboid or cube. I can not fine any class like
"vtkStructuredPointsOutlineFilter" in VTK, is there another way to do
this?</DIV>

<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2>Structured points data set is always brick
shaped. You can use vtkOutlineFilter which will output polydata outline. This
outline can be viewed using vtkPolyDataMapper.</FONT></DIV>
<DIV><FONT face=Arial size=2>Hope this will help you.</FONT></DIV>

<DIV>Hi, everyone:</DIV>
<DIV> </DIV>
<DIV>Can anybody tell me that how I can extract the exact outline (the shape
of dataset) from sturctured points? I have try to cast the structured points
to structured grid using the vtkCastToConcrete class, but I got lots of
strange errors.</DIV>
<DIV> </DIV>
<DIV>Thanks for anyone who can help me.</DIV>
