[vtkusers] How to use vtkTransform with vtkImageViewer2

[Uril Yakubov]

Hi ,

Does any now why my function getting slow and slow every time after I am
pushing pitch button(rotation around X).

proc Pitch_Command { } {

    // viewer is instance of vtkImageViewer2
    global  viewer

    set transform [vtkTransform New]
    $transform PostMultiply

    eval $transform  Identity

    eval $transform RotateX  1

    #VTK reslicer
    set reslice [vtkImageReslice New]
    eval $reslice SetResliceTransform  $transform 
    eval $reslice SetInput [$viewer GetInput]
    eval $reslice SetOutputDimensionality 3
    eval $reslice InterpolateOn
    eval $reslice SetInterpolationModeToCubic

    eval $viewer SetInput [$reslice GetOutput]
    
    eval $viewer Render

  
    $transform Delete
    $reslice Delete  
  
}

Thanks,

Uril.
