Is it possible to reduce the following to a single vector?

X3D code:
<Transform translation="-2.5 0 0" rotation="0 1 0 -1.570796">
<Viewpoint description="View 2" position="0 3 0" orientation="1 0
0 -0.785398"/>
</Transform>

VRML code (I think this is correct...):
Transform {
translation -2.5 0 0
rotation 0 1 0 -1.570796

children [
Viewpoint {
description "View 2"
position 0 3 0
orientation 1 0 0 -0.785398
}
]
}

Cheers,

Ben

This is not a single vector, it is a vector, another vector and a angle 8-)

Sorry for the delay, been working on a different project.

Thanks, thats what I was after.

Which version of Contact are you using?? I don't seem to have the option
available.
(I have another ~10 viewpoint to optimise).
