Aha, that works - thanks Ivan!
I'm sure I checked views >1, but maybe it was just doing
"nuke.OutputContex(2)", oh well,
cam = nuke.nodes.Camera2()
cam['translate'].splitView()
cam['translate'].setValue((1,1,1), 0, "left")
cam['translate'].setValue((22,22,22), 0, "right")
ctx = nuke.OutputContext()
ctx.setView(1)
print cam['transform'].value(ctx)
ctx.setView(2)
print cam['transform'].value(ctx)
..does exactly what I need \o/

Hi Ben,
Using an OutputContext to feed to ['transform'].value() should work.
To fill the OutputContext with the relevant view you'll need to use
<outputcontext>.setView(view_index) instead of the name of the view
directly.
Also, keep in mind that view 0 is always the "default" view, so if you
have "left" and "right" views, they will be indices 1 and 2, not 0 and 1.
So, to get the camera transform matrix from the right view (assuming you
have only left and right views), you should be able to do:
ctx = nuke.OutputContext()
ctx.setView(2)
camTransform = yourCameraNode['transform'].value(ctx)
Hope that helps.
Cheers,
Ivan

I'm trying to get the two transform matrix's from a stereo camera,
using the mycam['transform'].value() call, but I can't see anyway to
do this..
The value method doesn't take a view, only an OutputContext object,
which seems to have no effect:
cam = nuke.nodes.Camera2()
cam['translate'].splitView()
cam['translate'].setValue((1,__1,1), 0, "left")
cam['translate'].setValue((22,__22,22), 0, "right")
ctx_left = nuke.OutputContext("left")
print cam['transform'].value(ctx___left)
ctx_right = nuke.OutputContext("right")
print cam['transform'].value(ctx___right)
..at least in 6.2v3 and 6.3v1 that returns the matrix for whatever
the current view is. Also tried "ctx = nuke.OutputContext();
ctx.setView(0)" etc, same thing
I also tried:
for view in nuke.views():
nuke.activeViewer().setView(__view)
print "current view:", nuke.activeViewer().view()
print cam['transform'].value()
..which prints out the view, but still returns the same matrix
...and:
ct = nuke.nodes.CurveTool()
for view in nuke.views():
nuke.activeViewer().setView(__view)
nuke.execute(ct, nuke.frame(), nuke.frame())
print cam['transform'].value()
Any ideas? While I could manually create the matrix, that's a bit
tedious, especially given if there are any axis's parented.. Plus,
I'd also have to modify the nukescripts.snap3d methods I'm using
(which also don't take a view, although they use getValue etc which do)
