Formulas to get quaternion for axonometric views:

The angles alpha and beta depend on the type of axonometry
Isometric:
\code
alpha=45
beta=degrees(asin(-sqrt(1.0/3.0)))
\endcode
Dimetric:
\code
alpha=degrees(asin(sqrt(1.0/8.0)))
beta=degrees(-asin(1.0/3.0))
\endcode
Trimetric:
\code
alpha=30.0
beta=-35.0
\endcode
Verification code that the axonomtries are correct:
\code
from pivy import coin
c=Gui.ActiveDocument.ActiveView.getCameraNode()
vo=App.Vector(c.getViewVolume().getMatrix().multVecMatrix(coin.SbVec3f(0,0,0)).getValue())
