The final result shall be a dicom series which contains the surface consisting of values from the mesh point data. </div><div><br></div><div>The approach with a TriangularMesh SpatialObject which is passed to the SpatialObjectToImageFilter is very slow. If i just tell the filter the spacing, it resutls in an empty volume with some 1.0 on the top. Setting origin slows it down by more then ten times but draws the mesh on the right place. And the resulting values are either 1.0 or 0.0 (input data between [0.5, 5.0]).</div><div><br></div><div>Why is this filter so slow? </div><div>Is it better in itk 3.16 (i'm still using 3.14)? </div><div><br></div><div>I know the TriangularMeshToBinaryImageFilter works much faster but it's just binary and I need a surface. </div><div>Is there a good workaround? </div><div><br></div><div>Greets,</div><div>Andreas</div><div><br></div><div>Basic values:</div><div><div style="margin-top: 0px;
