Possible?: Building stereo pictures and depth maps using VTK

Hi. I have a friend who needs to produce both stereo images and depth
maps for a given scene. To clarify:
- the stereo images are just two views of the same scene taken from
different viewpoints (ie not red/green stereo)
- the depth maps are images where the intensity at a point is
proportional to the distance from the camera point to the first object
it hits (think: ray tracing). Black = infinity = the ray never hits any
object, while White = distance to closest object hit by a ray. I assume
that the range of distances are scaled into the range 1 .. 255 (they are
greyscale images).

Now, I'm pretty sure VTK can do the stereo rendering, but can it do the
depth map creation? It's important that the viewpoints used in the
stereo rendering and depth map creation are the same, and it'd be easier
to ensure this if the same program/toolkit was used.
