[vtkusers] from vtkRectilinearGridReader create planes

[psdc1978]

Hi,

I've a vtk file of type RECTILINEAR_GRID and I would like to create 3
planes, each for a type of coordinate (xx, yy and zz) but I don't know how
to do it. One plane must be parallel to the XX coordinate at the value 10,
another must be parallel to the YY coordinate at the value 25 and the third
must be in ZZ coordinate at the value 3.

Because the vtk file is a DATASET RECTILINEAR_GRID, I think that the only
way to load this file is using the vtkRectilinearGridReader object. But from
this object I don't know how to create the 3 planes. I really need to set
the origin values from each plane.

How can I do that?

I'm programming in TCL.

Here's the code:

VTK code
[code]
# vtk DataFile Version 1.0
Temperatures at mid-athmosphere
ASCII
DATASET RECTILINEAR_GRID
DIMENSIONS 90 60 5
X_COORDINATES 90 float

75 76 77 78 79
Z_COORDINATES 5 float
1 21 41 61 81

POINT_DATA 27000
SCALARS Temperature float
LOOKUP_TABLE default

[/code]

TCL code:
[code]
package require vtk

package require vtkinteraction

# Creation of the window
vtkRenderer ren1
vtkRenderWindow renWin
    renWin AddRenderer ren1

vtkRenderWindowInteractor iren
    iren SetRenderWindow renWin

vtkRectilinearGridReader reader
    reader SetFileName "dados_meteo_T_rg.vtk"
    reader Update

vtkRectilinearGridOutlineFilter plane1
    plane1 SetInput [reader GetOutput]

vtkPolyDataMapper planeMapper
    planeMapper SetInput [plane1 GetOutput]

vtkActor outlineActor
    outlineActor SetMapper planeMapper
    eval [outlineActor GetProperty] SetColor 0 0 0


ren1 AddActor outlineActor
ren1 SetBackground 1 1 1

iren Initialize

renWin SetSize 500 500
renWin Render

[/code]
