Sounds like all you need is a vtkImagePlaneWidget . There is an example which does that in the Example directory .<br><br>Regards<br>Darshan<br><br><div class="gmail_quote">On Thu, Jun 24, 2010 at 2:15 AM, Nizam de Abreu Pfeilsticker <span dir="ltr"><<a href="mailto:nizam.abreu@gmail.com">nizam.abreu@gmail.com</a>></span> wrote:<br>

<div>Since I am using <a href="http://VB.NET" target="_blank">VB.NET</a>, I cannot delete the actors or use smart pointers and usually I have memory problems if I don't shrink the image. Since I already have the plane (and the matrix4x4), can I have a function that returns me an 2D image (not the 3D one). It is important to be 2D because of memory issues. It would be perfect if I could have image as bitmap streamed to memory (like byte[])</div>
<div>It would be even better if I could retrieve this image from the DICOMs directly and not from the polydata I obtained using MarchingCubes (better resolution, since the image is not shrinked)</div>
<div>Did I make me clear?<br><br></div>
