[vtkusers] 3D Volume of 2D JPEG slices

[Bill Lorensen]

itkImageToVTKImageFilter handles RGB Images. Look at the ITKv4's VtkGlue module:
http://itk.org/gitweb?p=ITK.git;a=tree;f=Modules/Bridge/VtkGlue;h=495846dbaf6dc9a11b9f4f8c5238d560774cd248;hb=HEAD

You can see how RGB images are handled in QuickView.cxx
