i want to make a blood vessel model with 15 groups of x y z points by making a points for every 15 dicom view ( mri )

So, I composed and expressed the points and the triangular face of each point manually with polydata, but it is not smooth.

like this

Is it possible to take 15 (z) slice points (x,y) vtkpoints and express smooth surface?

sorry my english is short  
thanks
