You could fit a spline to your trajectory.
See examplesTcl/KSpline.tcl or CSpline.tcl

However, it seems as this works fine for straight poly lines, but when the trajectory is "curved", and the points are not so close the tube thing doesn't work (it looks ugly since the tube become discontinous). Is there anything else in vtk I can use to get a smoth tube along a 3D trajectory?
