<DIV dir=ltr align=left><SPAN class=433280415-30092008><FONT face=Arial
color=#0000ff size=2> It is certainly feasible to use a GPU and ITK.
There are a few options:</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=433280415-30092008><FONT face=Arial
color=#0000ff size=2></FONT></SPAN> </DIV>
<DIV dir=ltr align=left><SPAN class=433280415-30092008><FONT face=Arial
color=#0000ff size=2>1) Use GPU code inside an ITK filter. This would mean
writing GenerateData to do the processing on the GPU. An advantage is that
your code would become part of an ITK pipeline.</FONT></SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=433280415-30092008><FONT face=Arial
color=#0000ff size=2></FONT></SPAN> </DIV>
<DIV dir=ltr align=left><SPAN class=433280415-30092008><FONT face=Arial
color=#0000ff size=2>2) Use GPU code outside ITK. You would use ITK where
required, grab the output image buffer (from itkImage), and pass it to your GPU
code. This approach maintains flexibility as you can use your GPU code
outside of ITK as well as in conjunction.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=433280415-30092008><FONT face=Arial
color=#0000ff size=2>A good starting point is to look at the VTK-ITK glue code
(vtkITK in the NAMIC Sandbox). Here, ITK volumes are converted to VTK
volumes, and vice versa.</FONT></SPAN></DIV>
