<div>hi, i am now using vtk to do the surface reconstructionw work with the dicom data. i found that there is a filter called vtkContourFilter which seems helpful. But when i start to do some practice, i found that the speed and memory-consuming is unacceptable. And i also found that will not work if i did not apply a vtkImageGaussianSmooth filter first. Who could tell me how can that happen? and i think the vtkMarchingCubes filter also helpful, but it is patent protected.
</div>
<div>So after all, is there anyone could give me any suggestions? thanks</div>
