Hi all,<br>
<br>
i'm new to VTK and am looking for a filter similar to vtkDelaunay3D which takes vertices AND normals as input.<br>
<br>
I want to get a surface reconstruction from a point cloud and associated normals. The result should be a triangular mesh. The normals origin from a mesh which is lost or not available for me, but could be reconstructed by the additional information of the normals.<br>
The acceptance of normals is required because the anatomical structure of the left atrium is not truly convex:<br>

Thanks for any suggestions or workarounds!<br>
