[vtkusers] Re: how to render volumetric Data

[Valerie R Coffman]

Hi,

Which type of renderer and actor are you using?  

For volumetric data you need to use a vtkVolume instead of vtkActor and you need
to use one of the following mappers: vtkVolumeRayCastMapper,
vtkFixedPointVolumeRayCastMapper, vtkVolumeTextureMapper2D,
vtkVolumeTextureMapper3D.  Only the FixedPointVolumeRayCastMapper and
VolumeTextureMapper3D can handle images with more than one component, which your
tiffs will most likely be if they are color.  If they are grayscale, you might
have only one component and use one of the other mappers.  I've had the most
success with the FixedPointVolumeRayCastMapper.

BTW, a similar question was asked yesterday:
