vtkTexture not supporting 3D Texture?

Development

Hi,
I am supposed to use a 3d texture in my vtk application and use the same in shaders. Is this possible? I read somewhere that VTK do not support 3d textures. Is that true?

3D textures can be defined and used in VTK.

How do we define a 3D texture and use in VTK? Can you give some examples?
