<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I&#8217;m
looking for a pointer.<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>&nbsp;<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I&#8217;m
trying to display a resliced image, either axial, coronal, or sagital and then
display a contour representing the same plane cutting through a polygonal
shape.&nbsp; In my current example I have created a sphere which intersects
some of the image slices.&nbsp; As I scroll through the slices I expect to see
circles where the slice intersects the sphere.<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>&nbsp;<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Right
now I have created a SphereSource -&gt; ClipPolyData -&gt; PolyDataMapper -&gt;
Actor.&nbsp; The ClipPolyData has a plane as the clip function.<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>&nbsp;<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>For
the images I have ImageReslice -&gt; ImageMapToWindowLevelColors -&gt;
ImageActor<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>&nbsp;<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Both
of these actors are connected to a Renderer and added to a RenderWindow.<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>&nbsp;<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>What
I get is a slice and half of a sphere floating over it.&nbsp; I can&#8217;t get the
circle to be reflected on the image.&nbsp; I&#8217;ve also tried to use an
ImageViewer2 for the display to no avail.<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>&nbsp;<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>My
original plan was to sync the plane definitions in the ImageReslice and the
clipping plane, but I can&#8217;t get past this point.<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>&nbsp;<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>This
seems much more difficult than it needs to be.&nbsp; Is there a simpler way?<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>&nbsp;<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Thanks<o:p></o:p></p>
