Hi,

It’s not entirely clear what you mean by that. Do you have a computed tomography volume (so a 3D dataset) that you wish to render as a 2D image from some angle on screen or to a 2D image on disk? If so, have a look at VTK’s volume mappers.

Please explain a bit more what your input data looks like, and what your objective is, and we can better help you.
