[vtkusers] Draw a line ...help help :(

[leung fung man]

Dear All VT¢Ù¡@user:
I am a beginner user in VTK. I want to draw a line(construct by many points) 
on the screen when I input the XYZ coordinate.  I will update the coorindate 
by the encoder loop, and put the new coorindate into the following program 
to draw a new point to create a line on the screen.  I try the following 
program but can not work:--(
--------------------------------------
#draw the line path
vtkPoints points
	points InsertPoint 0 20 10 0 # I will call the coorindate from the encoder
vtkCellArray lines
	lines InsertCellPoint 0
vtkPolyDataNormals normalss
	normalss SetInput [lines GetOutput]
vtkLODActor linesActor
	linesActor SetMappper linesMapper
--------------------------------------
Please sent me some idea of this!
Any advise was great help on me!!
Merry X'mas for all VTK User!

Thank you very much

Best Regards,
German Leung
