<P>Giancarlo,</P>
<P> From your previous question - Clipping a vtkSphereSource might be a better way to get arcs out of a sphere, maybe you have figured that out already?. </P>
<P>Try vtkExtractEdges on the vtkSphereSource. I cant remember how a vtkSphereSource is structured but if you are lucky this might give parallels and meridians. Failing that you could cut (vtkCutter) the sphere with a set of planes (vtkPlaneCollection) placed and oriented to get the lines you want.</P>

<DIV></DIV>>Hello everybody,
<DIV></DIV>>
<DIV></DIV>>I have a vtkSphereSource visualized as points. I would connect that points
<DIV></DIV>>with isolines just like a geographics map with parallels and meridians
<DIV></DIV>>lines.
<DIV></DIV>>Any suggestions?
<DIV></DIV>>
<DIV></DIV>>thank a lot
