[vtkusers] volume texture support

[Lars Matthäus]

Hi,

Is there a way to create a texture for a 2d PolyData from the
intersection with an 3d ImageData? In detail, I'd like to implement a
curvilinear brain surface display in vtk (see e.g.
http://www.nibib.nih.gov/gallery/images/nibib_092605_082252.jpg ).
Therefore, I need to create the texture of each triangle of the PolyData
as the cut through underlying ImageData (voxels) of the brain, coming
e.g. from an MRI. Just like the vtkImagePlaneWidget, but for a curved
surface of a polydata.

Is such a feature available in VTK?

Thanks, Lars
