[vtkusers] Obtaining XYZ Coords

[Tron Darvann]

Hello,
 
I tried this:
set points [PolyData GetPoints]

set pointnumber 12

set point [$points GetPoint $pointnumber]

set xp [lindex $point 0]

set yp [lindex $point 1]
set zp [lindex $point 2]

puts stdout "$xp $yp $zp"

This prints the xyz coordinates of point number 12.

Btw. Do you know how to do the same with the polygons in tcl (e.g. getting point numbers for polygon number i)

Im trying to get the xyz coords (individually) from points in a mesh (using tcl)

Ive got as far as:
set points [[smoother GetOutput] GetPoints]
set point *[$points GetPoint $x]

but how do i then get from the vtkPoint point to the x, y and z numbers

thanks
