[vtk-developers] vtkWeightedTransformFilter added to contrib

[David Gobbi]

Hi Michael,

I've tried out banana.tcl, pretty neat ^-^

For the sake of similarity with othe VTK classes, you might want to
get rid of 'SetNumberOfTransforms()' and instead use
AddTransform()/RemoveTransform().  Take a look at
graphics/vtkAppendFilter.h or imaging/vtkImageMultipleInputFilter.h.

Also, you copied the 'LinearTransformVector' inline functions into
your code.  Why?  It would have been cleaner if you had just 
used transform->TransformPoint() and transform->TransformNormal()
directly for each if the input transforms.  

 - David
