[vtkusers] vtkVolumeTextureMapper3D in VTK 7.1?

[Simon ESNEAULT]

Hello Alvaro,

That's real good news to hear (about the down-sampling in X and Y), I find
it really difficult to tweak volume rendering only with sample distance,
especially during interaction.
Has the development began already ? Is there some branche where we can test
that feature ?

Also in that case would it be possible to add a final "gaussian smoothing
pass" or equivalent only on the 2D generated image (maybe only as an
option) ? I look like it is the case with FixedPointVolumeraycastMapper,
the image looks a bit blurred but sometimes it helps to see the structures

Thanks
Simon
