[vtkusers] 3D volume rendering via ray casting

[Joeri Nicolaes]

Hi all,

I tried to show a 3D volume with the ray casting approach, but I am struggling with the opacityTransferfunction. I have absolutely no clue how to "tune" this in order to show the right things. Af first, I have some head data and I used the transferfunction of an example in vtk showing a head. But now, I have some abdomenal data and I am stuck... 

Can anyone give me a tip? Perhaps a site or book with some figures to explain the effect of this opacityTransferfunction?

Thanks in advance,


Joeri,
