I have list of 2d images, I would like to visualize in 3d with volume rendering.

One way is to “merge” them and create a 3D volume dataset . See this filter [https://vtk.org/doc/nightly/html/classvtkImageAppend.html#details](https://vtk.org/doc/nightly/html/classvtkImageAppend.html#details) .

If your data are a DICOM image series you can also render it directly as volume [https://vtk.org/doc/nightly/html/classvtkDICOMImageReader.html#details](https://vtk.org/doc/nightly/html/classvtkDICOMImageReader.html#details)
