<br>
I've already read through the internet but couldn't find something to solve<br>
my problem.<br>
<br>
I've got 2D contour points for every slice from my CT.<br>
>From the registration of two CTs I get a 3D deformation field. With that I<br>
want to warp my contours from one CT to the other.<br>
But in order to do that I need something like a 3D mesh build from my<br>
contours.<br>
<br>
By now, every functionality I found requires for example triangles of points<br>
to create a mesh. But I just have the independent points per slice.<br>
<br>
So I wanted to ask If someone has an idea how to deal with that.<br>
<br>
Many thanks!<br>
<br>
