Vector optimisation....

| 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

Yes:
Viewpoint {
position -0.001 3.053 0.053
orientation -0.999 -0.030 -0.013 0.786
fieldOfView 0.785
description "View 3"
}
If you wonder how I did, I've been lazy: instead of calculing or using
a script, I simply ran the code in Contact and used the "copy viewpoint
to clipboard" function for having the resulting coordinates.

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