Hi all !<br>
<br>
Maybe the problem has already been exposed, and I'm sorry if it was.<br>
<br>
I've managed to made a basic DICOM Viewer. It has 4 views ; 3 views to axial, coronal ans sagittal orientation, and a tridimentionnal view for 3d reconstruction.<br>
<br>
I'm using igstk::View2D and igstk::View3D.<br>
<br>
I instantiate a CTImageSpatialObject in which I put the CT Image from the CTImageReader.<br>
Then I put the CTImageSpatialObject into a CTImageSpatialObjectRepresentation and I give it to the igstk::View2D.<br>
<br>
It's working properly and I can navigate into slides in the three 2D views.<br>
<br>
My problems is now how to perform a 3D reconstruction of the DICOM and display it in the 3D View.<br>
<br>
I've search on the net and on the mailing list for some help, but all this is still a little unclear to me.<br>
I just know that ITK and VTK has to be used, but I have no idea of how.<br>
<br>
If you can help me on that or at least show me the way for begin, I would be very greatfull.<br>
<br>
