[vtkusers] problem with translation

[Yaqian Fang]

Hi,

My application uses vtkStructuredPointsReader to read in a vtk file
which contains Structured Points for constructing a heart.  Then I use
vtkLineSource to draw some lines on the heart.  The points' values are
from the heart vtk file, but the result showed that the lines are far
away from the heart.  So I tried to translate those lines.  Strangely,
no matter which direction (X, Y, Z) I translate, those lines seem just
go around the heart, not any closer.  
Is it because heart and lines are from two different sources? Could
anyone kindly give me a hand on that please?  Thanks in advance!
