That's what I'm doing, with the code I posted at the beginning of the
thread, but it doesn't work, and I was wondering if I could get some
help from someone who would have done the same thing in the past.

Do this:
osgdistortion --dome cow.osg
Move the cow until it overlaps the junction of two slave cameras. You'll
see that the geometry matches, but the reflection mapping has a break in
it.
This is caused by the fact that the reflection mapping uses texture
coordinates generated in EYE_LINEAR mode, and each slave camera has a
different view matrix offset, and so the texture coordinates don't match.
The solution to that would be to use the master camera's view matrix to
compute the texture coordinates instead of each slave's view matrix.
That's what I'm trying to do.
I can't switch to using a world-space algorithm. The algorithm is by
definition eye-space (same with reflection mapping, it depends on the
reflected view vector, therefore on the eye position).
