[Insight-developers] Template metaprogramming magic coming toitk::Image?

[Lorensen, William E (Research)]

Zach,
This was our first attempt at metaprogramming magic. I expect that we will look to applying similar techniques in itkImage and maybe even some of the index calculations. As always we'll look for portable solutions.

I'm quite impressed with the efforts to make the itk::OrientedImage 
TransformPhysicalPointToIndex (etc.) methods fast through the use of 
clever template meta-programming.

Is there any plan to bring this technique to itk::Image? I've got some 
calls to these methods in some inner loops that really slows things 
down. I've resorted to partial-specialization type hacks, but it would 
be great to know if this was in the pipeline. (Or conversely, to know 
that it wasn't, so that maybe I'd give a crack at bringing them over to 
itk::Image myself.)

Zach
